Introduction Nitrous oxide is an inhalational anesthetic gas with analgesic and sedative properties. It is widely used in anesthesia practice and procedural sedation, especially for short procedures. It has a rapid onset and recovery due to low blood solubility. Nitrous oxide provides good analgesia but relatively weak anesthetic potency, so it is often used in … Read more
Introduction Nitroglycerin is an organic nitrate widely used in the management of angina pectoris and acute coronary syndromes. It acts as a potent vasodilator, primarily affecting venous capacitance vessels, thereby reducing cardiac workload. It also improves coronary blood flow and relieves ischemic chest pain. Nitroglycerin is considered a cornerstone drug for rapid relief of angina. … Read more
Introduction Loperamide is a peripherally acting opioid agonist widely used as an antidiarrheal agent. It effectively reduces intestinal motility and secretion without producing significant central nervous system effects at therapeutic doses. Unlike other opioids, loperamide has minimal abuse potential because it does not readily cross the blood-brain barrier due to active efflux mechanisms. It is … Read more
Introduction Lisinopril is a long-acting angiotensin-converting enzyme (ACE) inhibitor used mainly in hypertension, heart failure, and selected patients after acute myocardial infarction. It acts primarily by suppressing the renin-angiotensin-aldosterone system (RAAS), thereby reducing vasoconstriction, aldosterone release, and maladaptive cardiovascular remodeling. Because ACE is also involved in bradykinin breakdown, lisinopril may increase bradykinin levels, which contributes … Read more

Introduction H2 antagonists, also called H2 receptor blockers, are drugs used to reduce gastric acid secretion in conditions such as peptic ulcer disease, gastroesophageal reflux disease (GERD), and Zollinger–Ellison syndrome. These drugs block histamine H2 receptors located on gastric parietal cells, thereby inhibiting acid production. Common H2 antagonists include cimetidine, ranitidine, famotidine, and nizatidine. By … Read more

Introduction Glyceryl Trinitrate (GTN), commonly known as nitroglycerin, is an organic nitrate widely used in the treatment of angina pectoris and acute coronary syndromes. It acts primarily as a vasodilator by releasing nitric oxide (NO), which relaxes vascular smooth muscle. GTN reduces myocardial oxygen demand by decreasing preload and also improves coronary blood flow through … Read more
Introduction Folate, also known as vitamin B9, is a water soluble vitamin essential for DNA synthesis, cell division, and hematopoiesis. The biologically active form of folate is tetrahydrofolate, which functions as a carrier of one carbon units in multiple metabolic reactions. Folate plays a central role in nucleotide biosynthesis and methylation reactions, making it critical … Read more
