Complications of hypertension are by far the greatese preventable public health problem in many of the developed countries of the world. Pharmacologic interventions which primarily involve drug interactions are the generally available and effective means of preventing or delaying these hypertensive complications. Mechanisms of beneficial antihypertensive drug interactions involve simultaneous reduction or control of blood volume (diuretic agents) and decrease of peripheral resistance. Reduction of peripheral resistance without producing intolerable side effects has recetnly been achieved by a complex drug interaction. This interaction involves simultaneous vasodilation and inhibition by beta-adrenergic blocking agents of reflex activation of the renin-angiotensin axis. Clonidine, by effects similar to propranolol, can substitute for propranolol in some patients, or add to the beneficial effects of this important drug interaction.
Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.
