How Amlodipine and Benazepril works (mode of action)?

Amlodipine is used to reduce blood pressure and to prevent chest pain. Amlodipine is  calcium antagonist that  acts by inhibiting the calcium ion influx thus inhibits formation of  calcium- calmodulin complex.  Inhibition of calcium-calmodulin complex results inactivation of myosin light chain kinase (MLCK)  an important enzyme which catalyses muscle contraction. Overall, Amlodipine inhibits calcium ion influx which results in decreased contraction of arterial smooth muscle cells and vasodilation. Once Vasodilation occurs it causes significant reduction in the blood pressure.

Benazepril belongs to the class of angiotensin-converting enzyme (ACE) inhibitors in human subjects and animals. Angiotensin-converting enzyme is a peptidyl dipeptidase class of enzyme that catalyzes the conversion of angiotensin I to the vasoconstrictor substance, angiotensin II. This Angiotensin II is subsequently activated and stimulates adrenal cortex to secrete aldosterone. Inhibition of ACE by ACE inhibitors results in decreased plasma angiotensin II level. This reduction in ATII level leads to decreased vasopressor activity and aldosterone secretion. Besides this, studies also revealed a direct impact of Benazeprilat on kininase II, an enzyme identical to ACE that degrades the vasodilator bradykinin.
