title: Effects of minoxidil on blood pressure and cardiac hypertrophy in two-kidney, one-clip hypertensive rats.
abstract: Rats made severely hypertensive by renal arterial clipping were treated for 24 days with the arterial vasodilator minoxidil (40, 80, and 120 mg/L drinking water). In all three treated groups of animals, blood pressure initially decreased markedly and to a similar extent. Subsequently partial tolerance developed to the antihypertensive effects of minoxidil. All three doses induced hypertrophy of the right ventricle to a similar degree. In contrast, the hypertension-induced hypertrophy of the left ventricle was further increased in a dose-dependent fashion by minoxidil.
