Benazepril, brand name Lotensin, belongs to the class of drugs known as angiotensin-converting enzyme (ACE) inhibitors and is used primarily to lower high blood pressure (hypertension). This drug can also be used in the treatment of congestive heart failure and type II diabetes. Benazepril is a prodrug which, following oral administration, undergoes biotransformation in vivo into its active form benazeprilat via cleavage of its ester group by the liver. Angiotensin-converting enzyme (ACE) is a component of the body's renin–angiotensin–aldosterone system (RAAS) and cleaves inactive angiotensin I into the active vasoconstrictor angiotensin II. ACE (or kininase II) also degrades the potent vasodilator bradykinin. Consequently, ACE inhibitors decrease angiotensin II concentrations and increase bradykinin concentrations resulting in blood vessel dilation and thereby lowering blood pressure.

Spirapril (trade name: Renormax) belongs to the class of drugs known as angiotensin-converting enzyme (ACE) inhibitors and is used primarily to lower high blood pressure (hypertension). This drug can also be used in the treatment of congestive heart failure and type II diabetes. Spirapril is a prodrug which, following oral administration, undergoes biotransformation in vivo into its active form spiraprilat via cleavage of its ester group by the liver. Angiotensin-converting enzyme (ACE) is a component of the body's renin–angiotensin–aldosterone system (RAAS) and cleaves inactive angiotensin I into the active vasoconstrictor angiotensin II. ACE (or kininase II) also degrades the potent vasodilator bradykinin. Consequently, ACE inhibitors decrease angiotensin II concentrations and increase bradykinin concentrations resulting in blood vessel dilation and thereby lowering blood pressure.

Trandolapril (trade name: Mavik) belongs to the class of drugs known as angiotensin-converting enzyme (ACE) inhibitors and is used primarily to lower high blood pressure (hypertension). This drug can also be used in the treatment of congestive heart failure and type II diabetes. Trandolapril is a prodrug which, following oral administration, undergoes biotransformation in vivo into its active form trandolaprilat via cleavage of its ester group by the liver. Angiotensin-converting enzyme (ACE) is a component of the body's renin–angiotensin–aldosterone system (RAAS) and cleaves inactive angiotensin I into the active vasoconstrictor angiotensin II. ACE (or kininase II) also degrades the potent vasodilator bradykinin. Consequently, ACE inhibitors decrease angiotensin II concentrations and increase bradykinin concentrations resulting in blood vessel dilation and thereby lowering blood pressure.

Candesartan (also named Blopress or Atacand) is an active metabolite of angiotensin II receptor blockers (ARBs) pro drug, candesartan cilexetil. Candesartan cilexetil converts to candesartan rapidly in gastrointestinal tract during absorption. Candesartan competes with angiotensin II to bind type-1 angiotensin II receptor (AT1) in many tissues (e.g. vascular smooth muscle, the adrenal glands, etc.) to prevent increasing sodium, water reabsorption and peripheral resistance (that will lead to increasing blood pressure) via aldosterone secretion that is caused by angiotensin II. Therefore, action of candesartan binding to AT1 will result in decreasing blood pressure. For more information on the effects of aldosterone on electrolyte and water excretion, refer to the description of the spironolactone or triamterene pathways, which describes the mechanism of direct aldosterone antagonists. Candesartan is an effective agent for reducing blood pressure and may be used to treat essential hypertension and heart failure.

Eprosartan (also named Teveten) is an antagonist of angiotensin II receptor blockers (ARBs). Eprosartan competes with angiotensin II to bind type-1 angiotensin II receptor (AT1) in many tissues (e.g. vascular smooth muscle, the adrenal glands, etc.) to prevent increasing sodium, water reabsorption and peripheral resistance (that will lead to increasing blood pressure) via aldosterone secretion that is caused by angiotensin II.
