The purpose of this communication is to review mechanisms of action and hemodynamic effects of the commonly employed antihypertensive drugs.

Orally Given Diuretics  Of the various groups of antihypertensive drugs, the diuretics for oral administration have the greatest overall clinical usefulness. Their therapeutic advantages may be summarized as follows: (1) they lower blood pressures with the patient in both the supine and erect positions, (2) the overall incidence of side reactions accompanying their usage is low, (3) their antihypertensive effects are maintained despite prolonged administration, and (4) the orally given diuretics
