Where Antihypertensives Act

Every drug that lowers blood pressure does it by pulling on one of two levers: how much blood the heart pumps, or how tight the small arteries are. Tap a group to see which lever it pulls.

The slider is an illustration of the design idea, not measured data. Sarazine exists only on paper: it would need synthesis, enzyme assays, isolated vessel work, animal studies and clinical trials before any of this could be claimed.
