Classification of pharmaceutical products MCQs With Answer

by

Classification of pharmaceutical products MCQs With Answer is an essential study resource for B. Pharm students aiming to master drug categorization by chemical class, pharmacological classification, therapeutic class, origin, dosage form, and regulatory status. This introduction explains key classification systems — ATC coding, Biopharmaceutics Classification System (BCS), legal schedules, biologics versus small molecules, and OTC versus prescription distinctions — to build conceptual depth for rational prescribing, pharmacy practice, and regulatory exams. Emphasis is on mechanisms of action, target organs, physicochemical properties (solubility, permeability, lipophilicity), and clinical implications such as narrow therapeutic index and controlled substances. Now let’s test your knowledge with 30 MCQs on this topic.
