Hematinics

Hematinics

Definition of Hematinics: Hematinics are agents that improve the hemoglobin content of the blood, thereby enhancing oxygen-carrying capacity. They are primarily used to treat anemia. Some Major Hematinic Agents:  1. Iron Preparations: Ferrous Sulfate, Ferrous Gluconate: Mechanism: Supply elemental iron for hemoglobin synthesis. Use: Iron deficiency anemia. Side Effects: Gastrointestinal upset, dark stools. Iron Sucrose, … Read more

Anemia

Definition of Anemia Anemia is a condition with decreased red blood cells (RBCs) or hemoglobin (Hb), reducing oxygen-carrying capacity and causing fatigue, weakness, and dyspnea. Types of Anemia Based on RBC Size (MCV): Microcytic (MCV < 80 fL): Iron deficiency, thalassemia, sideroblastic anemia. Normocytic (MCV 80–100 fL): Acute blood loss, chronic disease, hemolysis. Macrocytic (MCV … Read more
