This pharmaceutical drug is used to treat congestive heart failure, high blood pressure and many other medical conditions. Research and clinical studies prove it to be a very effective drug class for many, as it works by causing the blood vessels to become enlarged or dilated, and thus causing a reduction in the blood pressure. This lowering of the blood pressure makes it easier for the heart to pump blood and it can improve the function of a failing heart. In the United States, 10 ACE inhibitors are in use: Ramipril (Altace) Enalapril (Vasotec, Epaned) Quinapril (Accupril) Captopril (Capoten) Benazepril (Lotensin) Lisinopril (Prinivil, Zestril) Fosinopril (Monopril) Moexipril (Univasc) Trandolapril (Mavik) Perindopril (Aceon) NOTE...that the brand names of all of these above end with the suffix “pril”. NOW.. let’s take a closer look at this drug class, angiotensin-converting enzyme (ACE) inhibitors, these drugs are helpful in treating heart, blood vessel, and kidney problems... Mechanism of Action: The human body is an amazing organism…In order to regulate water and blood pressure, our body follows special mechanisms. For example when the blood pressure drops too low, the kidneys release renin into the bloodstream. Renin then reacts with a protein called angiotensinogen that is produced by the liver. As a result, they form angiotensin I. Then another reaction converts angiotensin I to angiotensin II, with the help of angiotensin-converting enzyme found in the respiratory system. This whole mechanism is known as Renin-angiotensin system (RAS). Angiotensin II is a powerful substance. It circulates around the body in the bloodstream and induces several changes on the cardiovascular system. Such as stimulating adrenal cortex to release adolsterone and Constricting or narrowing down the blood vessels around the body. Aldosterone increases the reabsorption of water and sodium in the tubules of the kidneys. As a result, The volume of the blood and the concentration of salt in the blood increase leading to high blood pressure. The constriction of blood vessels results in high pressure inside the vessels, which also means an increase in blood pressure. Both of these events cause the heart to exert more pressure while pumping blood into the main arteries. Hence, it reverses the low blood pressure but it can also lead to other cardiovascular disorders if it persists for a long time. ACE inhibitors reduce the impact of renin-angiotensin-aldosterone system (RAAS) on the blood pressure by inhibiting the angiotensin converting enzyme. As a result, The conversion of angiotensin I to angiotensin II is slowed down which brings about several changes in the cardiovascular system. The rate of water reabsorption in the kidneys drops and so volume of blood decreases. And the blood vessels relax and become dilated. Both of these factors “reduce the work load on the heart,” (this phrase is a simple explanation that the nurse might give to her patient to explain how the ACE inhibitor Tags: nursing videos, youtube nursing videos, youtube nursing channel, videos for nurses, nursing videos, nursing pathophysiology videos, patho videos for nurses, med surg videos, medical surgical nurses, medical surgical videos, pharmacology videos, nursing pharmacology, nursing pharmacology videos, pharmacology, ace inhibitors, ace drugs, classes of drugs, review of drugs,
