What this medicine is used for

The name of your medicine is Chemmart Perindopril tablets.

It contains the active ingredient perindopril erbumine.

Perindopril belongs to a group of medicines called angiotensin converting enzyme (ACE) inhibitors.

It is used to treat high blood pressure, heart failure or coronary artery disease.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.

This medicine is available only with a doctor's prescription.

High blood pressure

Everyone has blood pressure. This pressure helps to circulate blood all around the body. Your blood pressure may be different at different times of the day, depending on how busy or worried you are. You have high blood pressure (also known as hypertension) when your blood pressure stays higher than is needed, even when you are calm and relaxed.

There are usually no symptoms of high blood pressure. The only way of knowing that you have it is to have your blood pressure checked on a regular basis. If high blood pressure is not treated it can lead to serious health problems. You may feel fine and have no symptoms, but eventually it can cause stroke, heart disease and kidney failure.

Perindopril helps to lower your blood pressure.

Heart failure

Heart failure means that the heart muscle is not pumping blood strongly enough to circulate blood around the body properly. Heart failure is not the same as a heart attack and does not mean that the heart stops working. Some people may develop heart failure after having a heart attack, but there are a number of other causes of heart failure.

Heart failure may start off with no symptoms, but as the condition progresses, you may feel short of breath or get tired easily after light physical activity such as walking. Fluid may accumulate in different parts of the body, often first noticed as swollen ankles and feet. You may also wake up short of breath at night. In severe heart failure, symptoms like breathlessness may occur even at rest.

Perindopril helps to treat heart failure. If you follow your doctor's advice, your ability to perform daily activities may improve. You may breathe more easily, feel less tired and have less swelling.

Coronary Artery Disease

Coronary artery disease is narrowing of the vessels carrying blood to the heart. In patients with coronary artery disease, perindopril has been shown to reduce some of the risks, including heart attacks.

There is no evidence that this medicine is addictive.

Use in children

This medicine should not be used in children.

Before you take this medicine

When you must not take it

Do not take this medicine if:

  • You have diabetes or kidney impairment and are taking aliskiren-containing products to treat high blood pressure.
  • You are pregnant.
    Perindopril may affect your developing baby if you take it during pregnancy.
  • You are breastfeeding.
    It is not known if perindopril passes into human breast milk.
  • You are undergoing renal dialysis using polyacrylonitrile membranes.
  • You have unilateral or bilateral renal artery stenosis
    (narrowing of the blood vessels to one or both kidneys).
  • You have experienced swelling of the face, tongue, lips or throat, either suddenly or in response to another ACE inhibitor medicine
    (a rare allergic condition known as angio-oedema).
  • You are hypersensitive to, or have had an allergic reaction to, perindopril or any of the ingredients listed at the end of this leaflet.
    Symptoms of an allergic reaction may include: cough, shortness of breath, wheezing or difficulty breathing; swelling of the face, lips, tongue, throat or other parts of the body; rash, itching or hives on the skin; fainting; or hay fever-like symptoms.
    If you think you are having an allergic reaction, do not take any more of the medicine and contact your doctor immediately or go to the Accident and Emergency Department at the nearest hospital.
  • You are intolerant or allergic to lactose.
    This medicine contains lactose.
  • The expiry date (EXP) printed on the pack has passed.
  • The packaging is torn, shows signs of tampering or it does not look quite right.

Before you start to take it

Tell your doctor if:

  1. You have allergies to:

How to take this medicine

Follow carefully all directions given to you by your doctor. Their instructions may be different to the information in this leaflet.

How much to take

Your doctor will tell you how much of this medicine you should take. This will depend on your condition and whether you are taking any other medicines.

Do not stop taking your medicine or change your dosage without first checking with your doctor.

The usual starting dose for high blood pressure or coronary artery disease is 4 mg once daily, which may be increased by your doctor up to 8 mg once daily.

The usual starting dose for heart failure is 2 mg once daily, which may be increased by your doctor up to 4 mg once daily.

Elderly people can generally use perindopril safely. However, some older people have reduced kidney function, in which case the starting dose of perindopril should be 2 mg once daily. A less frequent dose may be prescribed with serious kidney failure.

How to take it

Swallow your tablet(s) with a glass of water, before a meal.

When to take it

Take it at about the same time each day, preferably in the morning before a meal.

Taking your medicine at the same time each day will have the best effect. It will also help you remember when to take it.

How long to take it for

Continue taking your medicine for as long as your doctor tells you.

Perindopril can help control your condition, but cannot cure it.

Make sure you have enough to last over weekends and holidays.

If you forget to take it

If it is almost time to take your next dose, skip the missed dose and take your next dose at the usual time. Otherwise, take it as soon as you remember and then go back to taking your medicine as you would normally.

Do not take a double dose to make up for missed doses.

This may increase the chance of you experiencing side effects.

If you have trouble remembering to take your medicine, ask your pharmacist for some hints to help you remember.

If you take too much (overdose)

If you think that you or anyone else may have taken too much of this medicine, immediately telephone your doctor or the Poisons Information Centre (Tel: 13 11 26 in Australia) for advice. Alternatively, go to the Accident and Emergency Department at your nearest hospital.

Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

If you take too much your blood pressure may fall (also known as hypotension), which can make you feel dizzy or faint.

Brand name

Chemmart Perindopril Tablets

Active ingredient

Perindopril erbumine




Name of the medicine

Perindopril erbumine.


Anhydrous lactose and magnesium stearate.


Chemical name: 2-methylpropan-2-amine (2S,3aS,7aS)-1-[(2S)-2-[[(1S)-1-(ethoxycarbonyl)butyl]amino]propanoyl] octahydro-1H-indole-2-carboxylate. Molecular formula: C19H32N2O5,C4H11N. CAS: 107133-36-8.
Perindopril is a dipeptide monoacid monoester with a perhydroindole group and no sulfhydryl radical. Perindopril erbumine is a white powder, readily soluble in purified water, 95% ethanol and chloroform. Perindopril has five asymmetric centres and is synthesised stereoselectively so that it is a single enantiomer (all S stereochemistry).
Perindopril erbumine is an angiotensin converting enzyme inhibitor.
Each tablet contains perindopril erbumine as the active ingredient. In addition each tablet contains the following inactive ingredients: lactose anhydrous and magnesium stearate.


Pharmacological actions.

Perindopril (prodrug), following hydrolysis to perindoprilat, inhibits angiotensin converting enzyme (ACE) both in vitro and in vivo. It is thought that ACE inhibitors reduce blood pressure by inhibiting the enzyme which catalyses the conversion of angiotensin I to angiotensin II. Decreased plasma angiotensin II leads to increased plasma renin activity and a decrease in aldosterone. In addition to its effects on circulating ACE, perindopril binds to and inhibits tissue converting enzyme, predominantly in the kidney and vascular wall. The contribution of this mechanism to the overall antihypertensive effect of perindopril is unknown. Animal studies have demonstrated reversal of vascular hypertrophy and an improvement in the ratio of elastin to collagen in the vessel wall. Studies in humans have demonstrated an improvement in the viscoelastic properties of large vessels and in compliance. Studies in animals and humans suggest that specific and competitive suppression of the renin angiotensin aldosterone system is the main mechanism by which blood pressure is reduced. However, antihypertensive activity has also been observed in patients with low renin activity. Perindopril may also inhibit the degradation of the potent vasodepressor peptide bradykinin and this action may contribute to its antihypertensive action. Perindopril appears to reduce peripheral resistance and may influence arterial compliance.
Studies carried out in animal models of hypertension have shown that perindopril is a specific competitive angiotensin I converting enzyme inhibitor. The administration of perindopril to patients with essential hypertension results in a reduction in supine and standing blood pressure without any significant effect on heart rate. Abrupt withdrawal of perindopril has not been associated with a rebound rise in blood pressure. Single dose studies have demonstrated that peak inhibition of ACE activity and peak reduction in blood pressure occurs four to six hours after administration. The duration of these effects are dose related and, at the recommended dose range, both effects have been shown to be maintained over a 24 hour period.
In haemodynamic studies carried out in animal models of hypertension, blood pressure reduction after perindopril administration was accompanied by a reduction in peripheral arterial resistance and improved arterial wall compliance. In studies carried out in patients with essential hypertension the reduction in blood pressure was accompanied by a reduction in peripheral resistance with no change or a small increase in renal blood flow, and no change in glomerular filtration rate. An increase in the compliance of large arteries was also observed. When perindopril is administered together with a thiazide type diuretic, the antihypertensive activity of perindopril may be potentiated in some patients and this effect is evident after four weeks of treatment. Perindopril, like other ACE inhibitors, may compensate for thiazide induced hypokalaemia.
In one study of 48 patients when low dose perindopril (2.0 mg) was compared with correspondingly low doses of enalapril (2.5 mg) or captopril (6.25 mg) in patients with congestive heart failure, significantly different blood pressure responses were noted. Blood pressure fell significantly with captopril and enalapril following the first dose. However, while perindopril inhibited plasma ACE comparably with enalapril, the blood pressure changes were insignificant and similar to placebo for up to ten hours of regular observation. Data regarding the possibility of a late hypotensive response are not available for perindopril.



Following oral administration, perindopril is rapidly absorbed with a bioavailability of 24%. Elimination is rapid, occurring predominantly via the urine. Plasma half-life is approximately one hour. Bioavailability of the active metabolite perindoprilat is approximately 27%.


Peak plasma concentrations of perindoprilat occur three to four hours after oral administration of perindopril and protein binding of perindoprilat is 20%, principally to ACE. When perindopril is administered chronically, steady state of perindoprilat concentration is reached within four days, and perindoprilat does not accumulate.


Apart from perindoprilat, the administration of perindopril leads to the formation of five other metabolites, all of which are inactive and exist in very low quantities. One of these is the glucuronoconjugate of perindoprilat which is formed by a hepatic first-pass effect. This effect does not appear to have any influence on the kinetics of perindoprilat. Food intake may reduce hepatic biotransformation to perindoprilat.


Perindoprilat binds to plasma and tissue ACE and free perindoprilat is eliminated through the urine. The terminal half-life of the unbound fraction is approximately 17 hours.
The terminal half-life, which corresponds to the disassociation of perindoprilat from ACE, is approximately 25 to 30 hours.
The elimination of perindoprilat is reduced in elderly patients and in patients with cardiac and renal failure (see Dosage and Administration).

Clinical Trials

Patients with stable coronary artery disease.

The effects of perindopril were compared to placebo in patients with stable coronary artery disease with no clinical signs of heart failure. The EUROPA (European trial on Reduction Of cardiac events with Perindopril in stable coronary Artery disease) study was a multicentre, international, randomised, double blind, placebo controlled clinical trial lasting 4 years. 12,218 patients aged over 18 were randomised: 6110 patients to high dose perindopril 8 mg and 6108 patients to placebo.
The primary endpoint was the composite of cardiovascular mortality, nonfatal myocardial infarction, and/or cardiac arrest with successful resuscitation.
The trial population had evidence of coronary artery disease documented by previous myocardial infarction at least 3 months before screening, coronary revascularisation at least 6 months before screening, angiographic evidence of stenosis (at least 70% narrowing of one or more major coronary arteries), or positive stress test in men with a history of chest pain.
Study medication was added to conventional treatment, including medication used for the management of hyperlipidaemia, hypertension and diabetes mellitus. Patients randomised to perindopril were initiated on perindopril 2 mg or perindopril 4 mg for 2 weeks, and then titrated up to perindopril 8 mg during the 2 following weeks. Perindopril 8 mg was then maintained for the whole duration of the study. If this dose was not well tolerated, it could be reduced to perindopril 4 mg once daily.
Most of the patients also received platelet inhibitors, lipid lowering agents and beta-blockers. At the end of the study, the proportions of patients treated with a combination of these medications were 91%, 69% and 63% respectively.
The results of the EUROPA study, specifically the primary endpoint and its components (cardiovascular mortality, nonfatal myocardial infarction or resuscitated cardiac arrest) for the intention to treat (ITT) population are presented in Table 1.
The reduction in the primary composite endpoint was mainly due to a reduction in the number of nonfatal myocardial infarctions. There was no significant reduction in the rate of cardiovascular mortality or total mortality in patients taking perindopril compared to those taking placebo.
After a mean follow-up of 4.2 years, treatment with perindopril erbumine 8 mg once daily resulted in a significant relative risk reduction of 20% (95% CI: 9-29) in the primary combined endpoint: 488 patients (8.0%) reported events in the perindopril group compared to 603 patients (9.9%) in the placebo group (p = 0.0003). Improvements in the primary composite endpoint achieved statistical significance after 3 years of continuous treatment on perindopril.


Treatment of hypertension.
Treatment of heart failure.
In such patients it is recommended that perindopril be given with a diuretic and/or digoxin under close medical supervision. (The safety and efficacy of perindopril have not been demonstrated for New York Heart Association category IV patients).
Patients with established coronary artery disease (see Clinical Trials), who are stable on concomitant therapy and have no heart failure, to reduce the risk of nonfatal myocardial infarction or cardiac arrest.


Perindopril is contraindicated in the following.
History of previous hypersensitivity to perindopril or to any component of the formulation.
During pregnancy and for lactating women.
Bilateral or unilateral renal artery stenosis.
Patients with a history of hereditary and/or idiopathic angioedema, or angioedema associated with previous treatment with an angiotensin converting enzyme (ACE) inhibitor (see Precautions).
Patients haemodialysed using high flux polyacrylonitrile (AN69) membranes who are highly likely to experience anaphylactoid reactions if they are treated with ACE inhibitors. This combination should therefore be avoided, either by use of alternative antihypertensive drugs or alternative membranes (e.g. cuprophane or polysulphone).
Combined use with aliskiren containing products in patients with diabetes or renal impairment (GFR < 60 mL/min/1.73 m2) (see Interactions with Other Medicines and Precautions).



Since ACE inhibitors reduce angiotensin II formation resulting in decreased production of aldosterone, increases in serum potassium have been observed in some patients treated with ACE inhibitors including perindopril. Serum electrolytes (including sodium potassium and urea) should be measured from time to time when ACE inhibitors are given, especially when diuretics are also prescribed.
Hyperkalaemia can cause serious, sometimes fatal, arrhythmias. Risk factors for the development of hyperkalaemia include those with renal insufficiency, worsening of renal function, age (> 70 years), diabetes mellitus, intercurrent events, in particular dehydration, acute cardiac decompensation, metabolic acidosis and concomitant use of potassium sparing diuretics (e.g. spironolactone, eplerenone, triamterene, or amiloride), potassium supplements or potassium containing salt substitutes; or those patients taking other drugs associated with increases in serum potassium (e.g. heparin). Concomitant use of the above mentioned agents should be used with caution. Frequent monitoring of serum potassium is needed (see Interactions with Other Medicines). In some patients hyponatraemia may coexist with hyperkalaemia.

Diabetic patients.

Glycaemic control should be closely monitored during the first month of treatment with an ACE inhibitor in patients with diabetes treated with oral medicines or insulin (see Interactions with Other Medicines).


The combination of lithium and perindopril is generally not recommended (see Interactions with Other Medicines).

Potassium sparing drugs, potassium supplements or potassium containing salt substitutes.

The combination of perindopril and potassium sparing drugs, potassium supplements or potassium containing salt substitutes is generally not recommended (see Interactions with Other Medicines).


Patients with a history of angioedema unrelated to ACE inhibitor treatment may be at increased risk of angioedema while treated with an ACE inhibitor.
Life threatening angioedema has been reported with most of the ACE inhibitors. The overall incidence is approximately 0.1 to 0.2%. The aetiology is thought to be nonimmunogenic and may be related to accentuated bradykinin activity. Usually the angioedema is nonpitting oedema of the skin, mucous membrane and subcutaneous tissue.
Angioedema of the face, extremities, lips, tongue, mucous membranes, glottis and/or larynx has been reported in patients treated with ACE inhibitors and has been reported uncommonly with perindopril (see Adverse Effects). This may occur at any time during treatment. In such cases, perindopril should be promptly discontinued and the patient carefully observed until the swelling disappears.
Where such cases have been described with other ACE inhibitors and swelling has been confined to the face and lips, the condition has generally resolved without treatment although antihistamines have been useful in relieving symptoms. Angioedema associated with laryngeal oedema may be fatal or near fatal. In most cases symptoms occurred during the first week of treatment and the incidence appears to be similar in both sexes or those with heart failure or hypertension.
Where there is involvement of the tongue, glottis or larynx likely to cause airway obstruction, appropriate treatment (e.g. adrenaline and oxygen) should be given promptly. Treatment of progressive angioedema should be aggressive and, failing a rapid response to medical treatment, mechanical methods to secure an airway should be undertaken before massive oedema complicates oral or nasal intubation.
Patients who respond to medical treatment should be observed carefully for a possible rebound phenomenon. The onset of angioedema associated with the use of ACE inhibitors may be delayed for weeks or months. Patients may have multiple episodes of angioedema with long symptom free intervals. Angioedema may occur with or without urticaria.
Intestinal angioedema has been reported rarely in patients treated with ACE inhibitors. These patients presented with abdominal pain (with or without nausea or vomiting); in some cases there was no prior facial angioedema and C-1 esterase levels were normal. The angioedema was diagnosed by procedures including abdominal CT scan, or ultrasound or at surgery and symptoms resolved after stopping the ACE inhibitor. Intestinal angioedema should be included in the differential diagnosis of patients on ACE inhibitors presenting with abdominal pain.
ACE inhibitors should not be reintroduced in patients who have a history of angioedema due to rare reports of recurrence.

Anaphylactoid reactions during low density lipoproteins (LD) apheresis.

Rarely, patients receiving ACE inhibitors during low density lipoprotein (LDL) apheresis with dextran sulphate have experienced life threatening anaphylactoid reactions. These reactions were avoided by temporarily withholding ACE inhibitor therapy prior to each apheresis.
Anaphylactoid reactions have been reported in patients dialysed with high flux membranes, who are treated with an ACE inhibitor. In these patients consider using a different type of dialysis membrane or a different class of antihypertensive medicines (see Contraindications).

Anaphylactic reactions during desensitisation.

Patients treated with ACE inhibitors during desensitisation treatment (e.g. hymenoptera venom) have experienced anaphylactoid reactions. In the same patients, these reactions have been avoided when the ACE inhibitors were temporarily withheld, but they reappeared upon inadvertent rechallenge.


Hypotension has been reported in patients commencing treatment with ACE inhibitors. Symptomatic hypotension is rarely seen in uncomplicated hypertension but is a potential consequence of perindopril use in salt/ volume depletion, for example, in patients vigorously treated with diuretics, in patients on dialysis, with impaired renal function, following severe diarrhoea or vomiting, in patients on dietary restrictions or those with severe renin dependent hypertension (see Precautions, Interactions with Other Medicines and Adverse Effects).
Administration of perindopril 2 mg to patients with mild to moderate heart failure was not associated with any significant reduction in blood pressure.
In patients with symptomatic heart failure, with or without associated renal insufficiency, symptomatic hypotension has been observed. This is more likely to occur in those patients with severe heart failure, as reflected by the use of high doses of loop diuretics, hyponatraemia or functional renal impairment. This may be associated with syncope, neurological deficits, oliguria and/or progressive increase in blood nitrogen, and rarely with acute renal failure and/or death. Because of the potential fall in blood pressure in these patients, treatment should be started at low doses under very close supervision. Such patients should be followed closely for the first two weeks of treatment and whenever the dose is increased, or diuretic treatment is commenced or increased.
Patients with ischaemic heart or cerebrovascular disease in whom an excessive fall in blood pressure could result in myocardial infarction or cerebrovascular accident should be closely followed for the first two weeks of treatment and whenever the dose of perindopril and/or diuretic is increased. In all high risk patients it is advisable to initiate treatment with perindopril 2 mg.
In some patients with congestive heart failure who have normal or low blood pressure, additional lowering of systemic blood pressure may occur with perindopril. This effect is anticipated and is usually not a reason to discontinue treatment. If hypotension becomes symptomatic, a reduction of dose or discontinuation of perindopril may be necessary.
If hypotension occurs, the patient should be placed in a supine position and if necessary infused with normal saline. A transient hypotensive response is not a contraindication to further doses, which can usually be given without difficulty when blood pressure has increased following volume expansion.

Renal impairment.

As a consequence of inhibiting the renin angiotensin aldosterone system (RAAS), changes in renal function may be anticipated in susceptible individuals. In patients with severe congestive heart failure whose renal function may depend on the activity of the RAAS, treatment with ACE inhibitors may be associated with oliguria and/or progressive increase in blood nitrogen, and rarely with acute renal failure and/or death.
In patients with symptomatic heart failure, hypotension following the initiation of treatment with ACE inhibitors may lead to further impairment in renal function. Acute renal failure, usually reversible, has been reported in this situation.
ACE inhibitors should be avoided in patients with known or suspected renal artery stenosis (see Contraindications).
In clinical studies in patients with hypertension and unilateral or bilateral renal artery stenosis, increases in blood urea nitrogen and serum creatinine were observed in 20% of patients. These increases are usually reversible upon discontinuation. When an ACE inhibitor is given to a patient with stenosis of the renal artery supplying a solitary kidney or bilateral renal artery stenosis, acute renal insufficiency may occur. ACE inhibition may also cause a decrease in renal function. Renal function may also be reduced in patients with stenosis of the artery supplying a transplanted kidney. It is believed that renal artery stenosis reduces the pressure in the afferent glomerular arteriole, and transglomerular hydrostatic pressure is then maintained by angiotensin II induced constriction of the efferent arteriole. When an ACE inhibitor is given, the efferent arteriole relaxes, glomerular filtration pressure falls, and renal failure may result. ACE inhibitors can lead to the thrombotic occlusion of a stenosed renal artery.
If renovascular hypertension is also present, treatment should be started under close medical supervision with low doses and careful dose titration. There is an increased risk of severe hypotension and renal insufficiency. Since treatment with diuretics may be a contributory factor to the above, they should be discontinued and renal function should be monitored during the first weeks of perindopril treatment.
Some patients with hypertension and no apparent pre-existing renovascular disease have developed increases in blood urea, nitrogen and serum creatinine, which are usually minor and transient, particularly when perindopril has been given in combination with a diuretic. However, increases in blood urea, nitrogen and serum creatinine are more likely to occur in patients with pre-existing renal impairment or those on diuretics. Dosage reduction of the ACE inhibitor and/or discontinuation of the diuretic may be required.
Renal function should always be assessed (see Dosage and Administration). In the case of renal impairment, the initial perindopril dose should be adjusted according to the patient's creatinine clearance (see Dosage and Administration). Routine monitoring of potassium and creatinine are part of normal medical practice for these patients (see Adverse Effects). If deterioration in renal function has occurred after treatment with one ACE inhibitor, then it is likely to be precipitated by another, and in these patients use of another class of antihypertensive agent would be preferable. Patients with unilateral renal artery disease present a special problem as deterioration of function may not be apparent from measurement of blood urea and serum creatinine.
Some ACE inhibitors have been associated with the occurrence of proteinuria (up to 0.7%) and/or decline in renal function in patients with one or more of the following characteristics: old age, pre-existing renal disease, concomitant treatment with potassium sparing diuretics or high doses of other diuretics, limited cardiac reserve or treatment with a nonsteroidal anti-inflammatory drug (NSAID).
Perindopril is dialysable with a clearance of 70 mL/minute.

Renal transplantation.

There is no experience regarding the administration of perindopril in patients with a recent kidney transplantation.

Hepatic failure.

Rarely, ACE inhibitors have been associated with a syndrome that starts with cholestatic jaundice and progresses to fulminant hepatic necrosis and (sometimes) death. The mechanism of this syndrome is not understood. Patients treated with ACE inhibitors who develop jaundice or marked elevations of hepatic enzymes should discontinue the ACE inhibitor and receive appropriate medical follow-up (see Adverse Effects).

Hepatic impairment.

Biotransformation of perindopril to perindoprilat occurs mainly in the liver. Studies in patients with hepatic impairment have shown that kinetic parameters of perindopril were not modified by hepatic failure. With the exception of bioavailability, which was increased, kinetic parameters of perindoprilat (including Tmax) were also unchanged. The increase in bioavailability could be due to inhibition of the formation of perindopril metabolites other than perindoprilat (see Pharmacology, Pharmacokinetics). The administration of perindopril leads to the formation of a glucuronoconjugate derivative of perindoprilat by a hepatic first-pass effect. The kinetic parameters of perindoprilat glucuronide are not modified by hepatic failure. The small changes in the kinetics of perindoprilat do not justify the need to change the usual dose in most patients with hepatic failure.


ACE inhibitors cause a higher rate of angioedema in patients of indigenous African origin than in patients of other racial origin. As with other ACE inhibitors, perindopril may be less effective in lowering blood pressure in people of indigenous African origin than in people of other racial origin, possibly because of a higher prevalence of low renin states in this population. It is unknown if the same observations have been made in patients of indigenous Australian origin.


A persistent dry (nonproductive) irritating cough has been reported with most of the ACE inhibitors. The frequency of reports has been increasing since cough was first recognised as a class effect of ACE inhibitor treatment with the incidence of cough varies between 2% and 15% depending upon the drug, dosage and duration of use.
The cough is often worse when lying down or at night and has been reported more frequently in women (who account for two-thirds of reported cases). Patients who cough may have increased bronchial reactivity compared with those who do not. The observed higher frequency of this side effect in nonsmokers may be due to a higher level of tolerance of smokers to cough.
The cough is most likely due to stimulation of the pulmonary cough reflex by kinins (bradykinin) and/or prostaglandins which accumulate because of ACE inhibition. Once a patient has developed intolerable cough, an attempt may be made to switch the patient to another ACE inhibitor; the reaction may recur but this is not invariably the case. A change to another class of drugs may be required in severe cases.


Perindopril treatment has occasionally been associated with mild or transient proteinuria (< 1 g per 24 hours). However in the majority of patients with pre-existing proteinuria treated with perindopril, proteinuria disappeared or remained stable. ACE inhibitors have potential to delay the progression of nephropathy in patients with diabetes, or hypertension.

Neutropaenia/ agranulocytosis/ thrombocytopenia/ anaemia.

Neutropenia/ agranulocytosis, thrombocytopenia and anaemia have been reported in patients treated with an ACE inhibitor. In patients with normal renal function and no other complicating factors, neutropaenia occurs rarely.
Perindopril should be used with extreme caution in patients with collagen vascular disease, immunosuppressant therapy, treatment with allopurinol or procainamide, or a combination of these complicating factors, especially if there is pre-existing impaired renal function. Some of these patients developed serious infections, which in a few instances did not respond to intensive antibiotic treatment. If perindopril is used in such patients, periodic monitoring of white blood cell counts is advised and patients should be instructed to report any sign of infection (e.g. sore throat, fever).

Dermatological reactions.

Dermatological reactions characterised by maculopapular pruritic rashes and sometimes photosensitivity have been reported with another ACE inhibitor. Rare and sometimes severe skin reactions (lichenoid eruptions, psoriasis, pemphigus-like rash, rosacea, Stevens-Johnson syndrome, etc). A causal relationship is difficult to assess.
Patients who develop a cutaneous reaction with one ACE inhibitor might not when switched to another drug of the same class, but there are reports of cross reactivity.

Taste disturbances (dysgeusia).

Taste disturbances were reported to be common (prevalence up to 12.5%) with high doses of one ACE inhibitor. The actual incidence of taste disturbance is probably low (< 0.5%) but data are scarce and difficult to interpret.
Taste disturbances with ACE inhibitors have been described as suppression of taste or a metallic sensation in the mouth. Dysgeusia usually occurs in the first weeks of treatment and may disappear in most cases within one to three months.

Agents causing renin release.

The effect of perindopril may be enhanced by concomitant administration of antihypertensive agents which cause renin release.

Dual blockade of the renin angiotensin aldosterone system (RAAS).

As a consequence of inhibiting the RAAS, hypotension, syncope, stroke, hyperkalaemia, and changes in renal function (including acute renal failure) have been reported in susceptible individuals, especially if combining medicines that affect this system. Dual blockade of the RAAS through the combined use of ACE inhibitors, angiotensin II receptor antagonist or aliskiren is therefore not recommended (see Contraindications and Interactions with Other Medicines). If dual blockade therapy is considered absolutely necessary, this should be limited to individually defined cases under specialist supervision with frequent, close monitoring of renal function, electrolytes and blood pressure.
The combination of Coversyl with aliskiren is contraindicated in patients with diabetes or renal impairment (GFR < 60 mL/min/1.73 m2) (see Contraindications and Interactions with Other Medicines).
ACE inhibitors and angiotensin receptor blockers should not be used in combination in patients with diabetic nephropathy.

Surgery and anaesthesia.

Perindopril may block angiotensin II formation secondary to compensatory renin release in patients undergoing major surgery during anaesthesia, with agents that produce hypotension, and cause further reduction in blood pressure. Treatment should be discontinued one day prior to the surgery. Perioperative hypotension can be corrected with volume expansion.

Aortic or mitral valve stenosis/ hypertrophic cardiomyopathy.

There has been some concern on theoretical grounds that patients with mitral valve stenosis and obstruction in the outflow of the left ventricle such as aortic stenosis or with hypertrophic cardiomyopathy might be at particular risk of decreased coronary perfusion when treated with vasodilators, including ACE inhibitors. Vasodilators may tend to drop diastolic pressure, and hence coronary perfusion pressure, without producing the concomitant reduction in myocardial oxygen demand that normally accompanies vasodilatation. The true clinical importance of this concern is uncertain.

Stable coronary artery disease.

If an episode of unstable angina pectoris, regardless of severity, occurs during the first month of perindopril treatment, a careful appraisal of the benefits/ risks of continuing treatment should be performed.

Lactose intolerance.

This medicine contains lactose. Patients with an intolerance to lactose, rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.

Effects on fertility.

Studies in rats showed no impairment of male or female fertility at oral perindopril erbumine doses up to 10 mg/kg/day.

Use in pregnancy.

(Category D)
The use of ACE inhibitors is contraindicated during pregnancy (see Contraindications).
As with all ACE inhibitors, perindopril should not be taken during pregnancy. Pregnancy should be excluded before starting treatment and avoided during treatment. Unless continued treatment with an ACE inhibitor is considered essential, patients planning pregnancy should be changed to alternative antihypertensive treatments which have an established safety profile for use in pregnancy. If a patient intends to become pregnant, treatment with ACE inhibitors must be discontinued and replaced by another form of treatment.
If a patient becomes pregnant while on ACE inhibitors, she must immediately inform her doctor to discuss a change in medication and further management.
Perindopril or its metabolites have been shown to cross the placenta and distribute to the foetus in pregnant animals.
There are no adequate and well controlled studies of ACE inhibitors in pregnant women, but foetotoxicity is well documented in animal models. Data, however, show that ACE inhibitors cross the human placenta. Postmarketing experience with all ACE inhibitors suggests that exposure in utero may be associated with hypotension and decreased renal perfusion in the foetus. ACE inhibitors have also been associated with foetal death in utero.
Epidemiological evidence regarding the risk of teratogenicity following exposure to ACE inhibitors during the first trimester of pregnancy has not been conclusive; however a small increase in risk cannot be excluded.
A historical cohort study in over 29,000 infants born to nondiabetic mothers has shown 2.7 times higher risk for congenital malformations in infants exposed to any ACE inhibitor during first trimester compared to no exposure. The risk ratios for cardiovascular and central nervous system malformations were 3.7 times (95% confidence interval 1.89 to 7.3) and 4.4 times (95% confidence interval 1.37 to 14.02) respectively, compared to no exposure.
When ACE inhibitors have been used during the second and third trimesters of pregnancy, there have been reports of foetal and neonatal toxicity: hypotension, hyperkalaemia, renal failure, skull hypoplasia, oligohydramnios and death.
Oligohydramnios has been reported, presumably resulting from decreased foetal renal function; oligohydramnios has been associated with foetal limb contractures, craniofacial deformities, hypoplastic lung development and intrauterine growth retardation. Prematurity and patent ductus arteriosus have been reported, however it is not clear whether these events were due to ACE inhibitor exposure or to the mother's underlying disease.
Infants exposed in utero to ACE inhibitors should be closely observed for hypotension, oliguria and hyperkalaemia. Should exposure to ACE inhibitors occur from the second trimester of pregnancy, ultrasound check of renal function and skull is recommended. If such complications arise, appropriate medical treatment should be initiated to support blood pressure and renal perfusion.

Use in lactation.

Animal studies have shown that perindopril and its metabolites are excreted in milk during lactation, but there are no human data. It is therefore recommended that perindopril should not be given to lactating women as the possible effect on the newborn is unknown. Alternative treatments with better established safety profiles during breastfeeding are preferable, especially while nursing a newborn or preterm infant.

Paediatric use.

Use of perindopril in children is not recommended as no data establishing safety and effectiveness in children are available.

Use in the elderly.

Renal insufficiency is commonly observed in elderly people. Care should therefore be taken when prescribing perindopril to elderly patients. The initial dose should always be 2 mg daily and patients should be monitored closely during the initial stages of treatment (see Dosage and Administration).
In a study of 91 elderly patients with a mean age of 71.9 years, a 6% increase in serum potassium occurred in the first month of treatment and subsequently remained stable. There was no change in the group in blood urea, creatinine or creatinine clearance.
Particular care should be taken in elderly patients with congestive heart failure who have renal and/or hepatic insufficiency.


Results from a broad set of assays for gene mutation and chromosomal damage with perindopril suggest no genotoxic potential at clinical doses.


No evidence of carcinogenic activity was observed in mice and rats when perindopril erbumine was administered via drinking water at levels up to 7.5 mg/kg/day for 2 years. At least one ACE inhibitor has caused an increase in the incidence of oxyphilic renal tubular cells and oncocytomas in rats. The potential of ACE inhibitors to cause this effect in humans is unknown. Moreover, the progression of oxyphilic cells to oncocytomas is rare in humans and when this occurs, it is considered benign.

Effect on laboratory tests.

Increases in blood urea and plasma creatinine, hyperkalaemia reversible on discontinuation may occur, especially in the presence of renal insufficiency, severe heart failure and renovascular hypertension. Elevation of liver enzymes and serum bilirubin have been reported rarely.

Effects on ability to drive or operate machinery.

The antihypertensive effect in individual cases may be symptomatic. Treatment with any blood pressure lowering agent may, therefore, affect the ability to drive, cross the road safely or operate machinery, especially at the start of treatment or when changing over from other preparations, or during concomitant use of alcohol.


Clinical trial data has shown that dual blockade of the renin angiotensin aldosterone system (RAAS) through the combined use of ACE inhibitors, angiotensin II receptor blockers or aliskiren is associated with higher frequency of adverse events such as hypotension, hyperkalaemia and decreased renal function (including acute heart failure) compared to the use of a single RAAS acting agent (see Contraindications, Precautions and Clinical Trials).

Medicines inducing hyperkalaemia.

ACE inhibitors can attenuate potassium loss caused by thiazide diuretics and increase serum potassium when used alone. Although serum potassium usually remains within normal limits, hyperkalaemia may occur in some patients treated with an ACE inhibitor. The combined use of an ACE inhibitor with a potassium sparing diuretic (e.g. spironolactone, triamterene, or amiloride), immunosuppressant (e.g. cyclosporin), angiotensin receptor blocker, NSAID, heparin, potassium supplement, or potassium containing salt substitute can increase the risk of hyperkalaemia. The combination of perindopril with the above mentioned medicines is not recommended (see Precautions). If combined use is indicated they should be used with caution and the patient's serum potassium monitored frequently.

Combined use which is contraindicated (see Contraindications and Precautions).


Patients with diabetes or renal impairment (GFR < 60 mL/min/1.73 m2), may be at risk of hypotension, syncope, stroke, hyperkalaemia and changes in renal function (including acute renal failure).

Combined use not recommended (see Precautions).


Patients other than those with diabetes or renal impairment may be at risk of hyperkalaemia, worsening of renal function and cardiovascular morbidity, and an increase in mortality (see Contraindications).

Combined use with ACE inhibitor and angiotensin receptor blocker.

It is reported in the literature that in patients with established atherosclerosis, heart failure, or diabetes with end organ damage, combined use with an ACE inhibitor and an angiotensin receptor blocker is associated with a higher frequency of hypotension, syncope, hyperkalaemia, and worsening renal function (including acute renal failure) as compared to use of a single RAAS agent. Dual blockade (e.g. by combining an ACE inhibitor with an angiotensin receptor blocker) should be limited to individually defined cases with close monitoring of renal function, serum potassium, and blood pressure.


Reversible increases in serum lithium concentrations and toxicity have been reported during concomitant administration of lithium with ACE inhibitors. Concomitant use of thiazide diuretics may increase the risk of lithium toxicity and enhance the already increased risk of lithium toxicity with ACE inhibitors. Use of perindopril with lithium is not recommended, but if the combination is necessary, careful monitoring of serum lithium levels should be performed (see Precautions).

Potassium sparing diuretics (e.g. triamterene, amiloride, potassium salts).

The combined use of perindopril and potassium sparing diuretics may result in potentially lethal hyperkalaemia especially in patients with renal impairment (additive hyperkalaemic effects). The combination of perindopril with the above mentioned medicines is not recommended (see Precautions). If the combination is required, it should be used with caution and with frequent monitoring of serum potassium. For use of spironolactone and eplerenone in heart failure, see Combined medicines which require special care.

Combined use which requires special care.

Medicines to treat diabetes (e.g. insulin, oral hypoglycaemic medicines).

ACE inhibitors may add to the glucose lowering effect, with risk of hypoglycaemia, in patients with diabetes who are treated with insulin or with oral hypoglycaemic medicines. Hypoglycaemia is very rare and appears to be more likely to occur during the first weeks of combined treatment, and in patients with renal impairment.


Baclofen may increase the antihypertensive effect of perindopril. Monitor blood pressure and adjust the dose of perindopril if necessary.

Nonpotassium sparing diuretics.

Patients treated with diuretics, especially those who are volume and/or salt depleted, may experience excessive reduction in blood pressure after initiation of treatment with an ACE inhibitor. The possibility of hypotensive effects can be reduced by discontinuation of the diuretic or by increasing volume or salt intake prior to commencing treatment with low and progressive doses of perindopril. If it is not possible to discontinue the diuretic, the starting dose of the ACE inhibitor should be reduced. The patient should be closely observed for several hours following the initial dose of the ACE inhibitor and until the blood pressure has stabilised. In arterial hypertension, when prior diuretic treatment has caused salt/ volume depletion, the diuretic must be discontinued before commencing treatment with the ACE inhibitor. A nonpotassium sparing diuretic can then be reintroduced, or the ACE inhibitor be commenced at a low dose and progressively increased. In diuretic treated congestive heart failure, the ACE inhibitor should be initiated at a very low dose, possibly after reducing the dose of the associated nonpotassium sparing diuretic.
In all cases, renal function (creatinine levels) must be monitored during the first few weeks of ACE inhibitor treatment.

Potassium sparing diuretics (eplerenone, spironolactone).

As the combination of perindopril and potassium sparing medicines (e.g eplerenone and spironolactone), potassium supplements or potassium containing salt substitutes is general not recommended.
Ensure patients do not have hyperkalaemia or renal impairment before commencing treatment with this combination.
There is a risk of potentially lethal hyperkalaemia with this combination in patients treated for NYHA class II-IV heart failure with a reduced ejection fraction, who have been previously treated with ACE inhibitors and loop diuretics. This risk is particularly high when recommendations for use of this combination have not been followed.
Weekly monitoring of serum potassium and creatinine levels is recommended in the first month of the treatment and, monthly thereafter.

Nonsteroidal anti-inflammatory medicinal products (NSAIDs) including aspirin > 3 g/day.

Medicines with prostaglandin synthetase inhibitor properties (e.g. indomethacin) or an NSAID (i.e. acetylsalicylic acid at anti-inflammatory dose regimens, nonselective NSAIDs or COX-2 inhibitors) may diminish the antihypertensive efficacy of concomitantly administered ACE inhibitors. However, clinical studies have not demonstrated any interaction between perindopril and indomethacin or other NSAIDs. Combination use of ACE inhibitors and NSAIDs may lead to an increased risk of worsening of renal function, including possible acute renal failure, and an increase in serum potassium, especially in patients with poor pre-existing renal function. The combination should be administered with caution, especially in the elderly. Patients should be adequately hydrated and consideration should be given to monitoring renal function after initiation of concomitant therapy, and periodically thereafter.

Combination use of ACE inhibitors, anti-inflammatory drugs and thiazide diuretics.

The combined use of an ACE inhibiting drug (ACE inhibitor or angiotensin receptor antagonist), an anti-inflammatory drug (NSAID or COX-2 inhibitor) and a thiazide diuretic at the same time increases the risk of renal impairment. This includes use in fixed combination products containing more than one class of drug. The combination of drugs from these three classes should be used with caution particularly in elderly patients or those with pre-existing renal impairment. Combined use of these medications should be accompanied by increased monitoring of serum creatinine, particularly at initiation.

Combined use which requires some care.


Nitritoid reactions (symptoms include facial flushing, nausea, vomiting and hypotension) have been reported rarely in patients treated with injectable gold (sodium aurothiomalate) and concomitant ACE inhibitor therapy including perindopril.

Antihypertensive agents and vasodilators.

Concomitant use of these agents may increase the hypotensive effects of perindopril. Concomitant use with nitroglycerin and other nitrates, or other vasodilators, may further reduce blood pressure.

Gliptins (e.g. linagliptin, saxagliptin, sitagliptin, vildagliptin).

When an ACE inhibitor and a gliptin are used in combination, there is an increased risk of angioedema due to the decreased activity of the dipeptidyl peptidase IV (DPP-IV).

Tetracycline and other drugs that interact with magnesium.

The simultaneous administration of tetracycline with an ACE inhibitor may significantly reduce the absorption of tetracycline, possibly due to the magnesium content in the ACE inhibitor tablets. This interaction should be considered if coprescribing an ACE inhibitor and tetracycline or other drugs that interact with magnesium.

Agents affecting sympathetic activity.

As the sympathetic nervous system plays an important part in physiological blood pressure regulation, caution should be exercised with concomitant administration of a drug with sympathetic activity and perindopril. Sympathomimetics may reduce the antihypertensive effects of ACE inhibitors.

Tricyclic antidepressants/ antipsychotics/ anaesthetics.

Concomitant use of certain anaesthetic medicinal products, tricyclic antidepressants and antipsychotics with ACE inhibitors may result in further reduction of blood pressure (see Precautions).

Adverse Effects

The safety profile of perindopril is consistent with the safety profile of ACE inhibitors. The most frequent adverse events reported in clinical trials and observed with perindopril are: dizziness, headache, paraesthesia, vertigo, visual disturbances, tinnitus, hypotension, cough, dyspnoea, abdominal pain, constipation, diarrhoea, dysgeusia, dyspepsia, nausea, vomiting, pruritus, rash, muscle cramps, and asthenia.

In total, 56 of 1,275 patients studied (4.4%) stopped treatment because of adverse reactions. In a specific study of 632 patients in which 36 patients (5.7%) withdrew because of adverse events. A plausible or probable relationship with perindopril treatment was considered to exist in 19 cases (3%).

Dosage and Administration

Food intake may reduce hepatic biotransformation of perindopril to perindoprilat. While this effect has not been shown to be clinically significant, it is recommended that perindopril should be taken before meals.

Renal impairment.

In patients with renal failure, treatment should begin with 2 mg daily. Dosage should be adjusted as indicated below according to creatinine clearance. Creatinine and potassium levels should be closely monitored.

ClCr between 30 and 60 mL/minute.

One 2 mg tablet daily.

ClCr between 15 and 30 mL/minute.

One 2 mg tablet every 2 days.

ClCr below 15 mL/minute.

One 2 mg tablet on day of dialysis (perindopril is dialysable (70 mL/minute)).


The usual starting dose of perindopril is 4 mg once daily, taken in the morning. Optimum control of blood pressure is achieved by increasing the dose, titrating it against the blood pressure to a maximum of 8 mg once daily.
A starting dose of perindopril 2 mg/day is recommended in the following patients who may be at risk of ACE inhibitor induced hypotension.

Combination with a diuretic.

The administration of perindopril to patients under current treatment with a diuretic may induce hypotension and sometimes, but more rarely, acute renal failure, at the beginning of the treatment. Monitoring of plasma creatinine is recommended during the first month of treatment.

Elderly patients.

Elderly patients with hypertension should start treatment with 2 mg daily, with titration to 4 mg if necessary. It is recommended that renal function be assessed before starting treatment.

Other patients who may be at risk of ACE inhibitor induced hypotension.

Patients with renovascular hypertension, salt and/or volume depletion, or cardiac decompensation may have a strongly activated RAAS. These patients may experience an excessive drop in blood pressure following the first dose of an ACE inhibitor.

Congestive heart failure.


Treatment of congestive heart failure with perindopril should be initiated under close medical supervision.
The usual starting dose of perindopril is 2 mg once daily, which should be given with a diuretic and/or digitalis. This is increased to 4 mg daily for maintenance.
Patients with severe hepatic or renal impairment and/or severe salt/ volume depletion are particularly sensitive to ACE inhibitors. Doses in these patients should be carefully titrated, as no pharmacokinetic and dose titration studies have been conducted.

Reduction of risk of cardiovascular events.

In patients with stable coronary artery disease, perindopril should be introduced at a dose of one 4 mg tablet once daily for two weeks, and then increased to one 8 mg tablet once daily, depending on tolerance and renal function.
Elderly patients should receive one 2 mg tablet once daily for one week, then one 4 mg tablet once daily the next week, before increasing the dose up to one 8 mg tablet once daily depending on tolerance and renal function (see Dosage and Administration, Renal impairment).


Limited data are available for overdose in humans.


Symptoms associated with overdose of ACE inhibitors may include hypotension, circulatory shock, electrolyte disturbances, renal failure, hyperventilation, tachycardia, palpitations, bradycardia, dizziness, anxiety and cough.


The recommended treatment of overdose is intravenous infusion of normal saline solution. If hypotension occurs, the patient should be placed in the shock position. If available, treatment with intravenous catecholamines may also be considered. Perindopril may be removed from the general circulation by haemodialysis (see Precautions). Vital signs, serum electrolytes and creatinine concentrations should be monitored continuously.
