    Study Notes

    Cardiovascular Pharmacology: Focus on ACE Inhibitors

    The term 'cardiovascular pharmacology' refers to the branch of medicine that deals with the study of drugs that affect the cardiovascular system. One of the critical aspects within this field is understanding the mechanisms of angiotensin-converting enzyme (ACE) inhibitors. These agents play a crucial role in managing various cardiovascular diseases, particularly hypertension, heart failure, and myocardial infarction.

    ACE inhibitors are a group of medications that inhibit the formation of angiotensin II, a powerful vasoconstrictor hormone produced by the renin-angiotensin-aldosterone system (RAAS). By reducing the level of angiotensin II, these inhibitors promote vasodilation and decrease preload and afterload, leading to improved blood flow and cardiac performance.

    Some notable examples of ACE inhibitors include captopril, enalapril, lisinopril, and ramipril. These drugs can be categorized into different types based on their chemical structures: sulfonylureas, benzothiazapes, and phosphonates. Each type has distinct characteristics such as bioavailability, duration of action, and metabolism.

    Although ACE inhibitors have a relatively low incidence of side effects, some patients may experience unwanted effects such as dry cough, hypotension, angioedema, and hyperkalemia. Moreover, these medications are contraindicated in certain situations, like severe aortic stenosis, severe hyperkalaemia, symptomatic hypotension, renovascular hypertension, pregnancy, and moderate renal insufficiency.

    In conclusion, ACE inhibitors represent a vital component in cardiovascular pharmacotherapy, with their unique ability to modulate the RAAS pathway and contribute to improved outcomes in various cardiovascular diseases.
