The Editorial Executive Committee welcomes letters, which should be less than 250 words. Before a decision to publish is made, letters which refer to a published article may be sent to the author for a response. Any letter may be sent to an expert for comment. When letters are published, they are usually accompanied in the same issue by their responses or comments. The Committee screens out discourteous, inaccurate or libellous statements. The letters are sub-edited before publication. Authors are required to declare any conflicts of interest. The Committee's decision on publication is final.
Editor, – I agree entirely with the sentiments of Dr O'Dempsey (Aust Prescr 2000;23:5) that newer drugs are rarely, if ever, measured against the performance of 'active' placebos. I think very few would pass muster if they were.
In the case of any antidepressant, I would personally be very surprised if any performed better than pheniramine p-aminosalicylate. I would be amazed if any hormone replacement therapy performed better than spironolactone100 mg second daily. I would be astounded if any anti-psoriasis treatment compared favourably against miconazole and zinc nappy ointment. I would also personally be stupefied if any ear drop could compare with half strength Burow's solution.
