4 Drug and Medication Information

4.1 Drug Indication

For the treatment of hypertension.

5 Pharmacology and Biochemistry

5.1 Pharmacology

Used to treat hypertension. Rescinnamine inhibits angiotensin-converting enzyme. ACE is a peptidyl dipeptidase that catalyzes the conversion of angiotensin I to the vasoconstrictor substance, angiotensin II. Angiotensin II also stimulates aldosterone secretion by the adrenal cortex and general vasoconstriction, both of which lead to increases vascular resistance. By inhibiting angiotensin II, aldosterone reabsorption is decreased as well as vasoconstriction. This combined effect serves to decrease blood pressure.

5.2 Mechanism of Action

Rescinnamine Binds to and inhibits the angiotensin converting enzyme. Rescinnamine competes with angiotensin I for binding at the angiotensin-converting enzyme, blocking the conversion of angiotensin I to angiotensin II. Inhibition of ACE results in decreased plasma angiotensin II. As angiotensin II is a vasoconstrictor and a negative-feedback mediator for renin activity, lower concentrations result in a decrease in blood pressure and stimulation of baroreceptor reflex mechanisms, which leads to decreased vasopressor activity and to decreased aldosterone secretion.
