Antihypertensive drugs are used commonly in anaesthesia and intensive care medicine. Patients might require antihypertensive drugs before surgery for the treatment of essential hypertension, pre-eclampsia or, occasionally for conditions such as phaeochromocytoma; during surgery as part of a deliberate hypotensive anaesthetic technique; or to reduce postoperative cardiovascular complications.
