Introduction to pharmacopoeias – IP, BP, USP, and Extra Pharmacopoeia MCQs With Answer

Introduction: Pharmacopoeias are authoritative reference books that set standards for drug identity, purity, strength, and quality, essential for B. Pharm students and future pharmacists. Key compendia include the Indian Pharmacopoeia (IP), British Pharmacopoeia (BP), and United States Pharmacopeia (USP), each providing official monographs, general chapters, and reference standards. Understanding monograph structure, tests (identification, assay, impurities), harmonization efforts, and the concept of Extra Pharmacopoeia resources is vital for quality control, regulatory compliance, and formulation development. This concise guide emphasizes practical principles, terminology, and differences among IP, BP, USP to prepare you for exams and lab practice. Now let’s test your knowledge with 30 MCQs on this topic.
