Classification & Mechanisms of Action Class & Examples Mechanism Key Indications COX-1 InhibitorsAspirin Irreversibly inhibits cyclooxygenase-1 (COX-1), blocking thromboxane A2 (TXA2) synthesis and platelet … Read more

Understanding Alteplase: The Tissue Plasminogen Activator You Need to Know

by
alteplase a tissue plasminogen activator

Introduction Alteplase (also referred to as recombinant tissue plasminogen activator or rt-PA) is a cornerstone of thrombolytic therapy, widely used to treat acute ischemic stroke, acute myocardial infarction, and other thromboembolic conditions. As a bioengineered form of tissue plasminogen activator (tPA), alteplase exerts its therapeutic effect by converting plasminogen to plasmin, thereby dissolving clots that obstruct blood flow … Read more

Hematinics and iron chelators

by
Hematinics

Hematinics are agents that supply essential substrates for erythropoiesis—principally iron, vitamin B12, and folate—while iron chelators remove excess iron from overload states; together, these drugs correct deficiency anemias and mitigate transfusional siderosis when used with appropriate monitoring and route selection. This chapter details classification, mechanisms, pharmacokinetics, indications, dosing, adverse effects, interactions, and evidence-based cautions for … Read more
