Trends in prescribing of antihypertensive drugs in Australia, 1977-1987.
Prescribing of hypotensive agents, beta-blockers and diuretics was analysed using data from the Pharmaceutical Benefits Scheme, adjusted to reflect prescribing for hypertension, over 1977-1987. Prescribing of these three drug groups combined increased by approximately 50% over the period. Notable trends were decreased prescribing of bendrofluazide, chlorothiazide and methyldopa and increased prescribing of hydrochlorothiazide with amiloride, atenolol, metoprolol and prazosin, and, most recently, captopril and enalapril. The increase in prescribing of drugs for hypertension, combined with the choice of more expensive drugs, has resulted in a substantial increase in the drug costs associated with treating hypertension.
