Editor, – Australian Prescriber Vol. 19 No. 4 1996 was accompanied by a card entitled 'Doses of selected emergency drugs'. Aminophylline was recommended for asthma not responding to nebulised salbutamol. The Canadian Medical Association Journal recently published guidelines for the emergency management of asthma.1 These guidelines were developed using an evidence-based medicine approach. The recommendation not to use aminophylline in the setting of the emergency department was grade A based on a meta-analysis of the results of 9 level I trials and 4 level II trials.2 The use of aminophylline appears to be associated with an increased risk of adverse effects. Aminophylline may have a role in the treatment of patients with severe acute asthma once the initial crisis in the emergency department has passed.
Doctor of Medicine
Dr Lexchin's letter was referred to Professor J.P. Seale who represents the Thoracic Society of Australia and New Zealand on the Advisory Editorial Panel of Australian Prescriber. Professor Seale concurs with Dr Lexchin. He also points out that the guidelines of the National Asthma Campaign3 state that the benefits of aminophylline are uncertain and so it should be reserved for adults who are unresponsive to maximal doses of beta2 agonists. The guidelines consider aminophylline to be unnecessary in the treatment of acute asthma in children.
