1. Introduction/Overview Erythropoietin (EPO) represents a critical glycoprotein hormone that serves as the principal regulator of red blood cell production, a process termed erythropoiesis. Endogenously synthesized primarily by peritubular interstitial fibroblasts in the renal cortex in response to tissue hypoxia, erythropoietin orchestrates the proliferation, differentiation, and survival of erythroid progenitor cells within the bone marrow. … Read more
Introduction/Overview Cyanocobalamin represents a synthetic, stable form of vitamin B12, a water-soluble micronutrient essential for human physiology. Its pharmacological significance extends beyond nutritional supplementation to the definitive treatment of specific hematological and neurological disorders resulting from cobalamin deficiency. The clinical relevance of cyanocobalamin is underscored by its role in managing pernicious anemia, a condition historically … Read more
Introduction/Overview Ferrous sulfate represents the prototypical and most widely utilized oral iron preparation for the treatment of iron deficiency. As an essential mineral, iron is a critical component of hemoglobin, myoglobin, and numerous enzymes involved in cellular respiration and energy metabolism. The pharmacology of ferrous sulfate encompasses its unique absorption, distribution, and utilization pathways, which … Read more
Introduction/Overview Streptokinase represents a cornerstone agent in the pharmacological management of acute thrombotic occlusions. Derived from ฮฒ-hemolytic streptococci, this protein functions as an indirect activator of the fibrinolytic system, converting plasminogen to plasmin. Its introduction revolutionized the treatment of acute myocardial infarction, establishing the principle that timely coronary reperfusion could salvage ischemic myocardium and reduce … Read more
1. Introduction/Overview Clopidogrel represents a cornerstone in the pharmacological management of atherothrombotic disease. As a thienopyridine antiplatelet agent, it is prescribed globally to reduce the risk of ischemic events in patients with acute coronary syndromes, recent myocardial infarction, stroke, or established peripheral arterial disease. The drug’s clinical importance stems from its ability to irreversibly inhibit … Read more
Introduction/Overview Heparin represents a cornerstone of anticoagulant therapy, belonging to the class of glycosaminoglycans. Its discovery in 1916 by Jay McLean and subsequent clinical introduction revolutionized the management of thrombotic disorders. As a naturally occurring substance, heparin’s primary pharmacological role is to accelerate the inhibition of coagulation proteases, thereby preventing the formation and extension of … Read more
Introduction/Overview Warfarin represents a cornerstone of oral anticoagulant therapy, with a clinical history spanning over seven decades. As a vitamin K antagonist, it exerts its therapeutic effect by interfering with the synthesis of biologically active clotting factors. The drug’s introduction followed the investigation of a hemorrhagic disease in cattle, leading to the isolation of the … Read more
Introduction/Overview Atorvastatin calcium represents a cornerstone agent in the management of dyslipidemia and the prevention of atherosclerotic cardiovascular disease. As a synthetic, potent inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase, it belongs to the statin class of medications, which have demonstrated significant mortality and morbidity benefits in large-scale clinical trials.
