Absorption is the process by which a drug enters the bloodstream, and bioavailability refers to the proportion of the drug that reaches the systemic circulation in an active form after administration. The bioavailability of a drug depends on various factors such as the route of administration, drug formulation, and the first-pass effect, where drugs absorbed from the gastrointestinal tract are partially metabolized by the liver before entering the systemic circulation. Oral drugs generally have lower bioavailability compared to intravenous drugs because they undergo partial breakdown in the liver. The lipid solubility of a drug, its molecular size, and the blood flow to the absorption site also play key roles in its bioavailability. Understanding absorption and bioavailability is critical in determining appropriate dosing, effectiveness, and therapeutic monitoring. 💊🔬💉 #pharmacokinetics #Absorption #Bioavailability #DrugMetabolism #GeneralPharmacology #DrugDelivery #FirstPassEffect #MedicalEducation #PharmacologyBasics
