Concomitant pathologies are frequent and may preclude the use of some of these agents, while other medicines taken by the patient interreact with them. Several complications of antihypertensive therapy particularly threaten elderly hypertensive drugs patients. The complications depend on the antihypertensive drugs used and include malaise, excessive fall in blood pressure, postural hypotension, water and electrolyte disorders, renal impairment and neuropsychological disturbances.
