antihypertensives;

Calcium-antagonists or calcium channel blockers. Used for 20 years, these drugs are against some of the mechanisms responsible for arterial vasoconstriction;

Inhibitors of angiotensin converting enzyme. ACE inhibitors inhibit the action of hormones – renin-angiotensin system and involved in the mechanisms of hypertension;

Central antihypertensives. These partially reduced the activity of the central nervous system involved in regulating blood pressure.

Alpha blockers. This class of antihypertensive drugs acting through a mechanism of expansion pressure.
