Phase I and Phase II metabolism MCQs With Answer Phase I and Phase II metabolism are central topics in drug biotransformation for B.Pharm students. Phase I reactions (oxidation, reduction, hydrolysis) introduce or expose functional groups primarily via cytochrome P450 enzymes, altering drug polarity and activity. Phase II reactions (conjugation) couple metabolites with endogenous donors—glucuronidation, sulfation, … Read more

Drug metabolism – principles and pathways MCQs With Answer This concise, student-focused introduction outlines core concepts of drug metabolism and biotransformation for B.Pharm candidates. You will review phase I (oxidation, reduction, hydrolysis) and phase II (conjugation) pathways, major enzyme systems such as CYP450, UGTs and transferases, and clinically important ideas like first-pass metabolism, prodrugs, enzyme … Read more

Physicochemical properties and drug activity explores how molecular characteristics such as solubility, lipophilicity (log P/log D), pKa, permeability, crystal form, and stability influence drug absorption, distribution, metabolism, excretion, and pharmacodynamics. For B.Pharm students, mastering these concepts links chemistry to therapeutic effect—predicting bioavailability, optimizing salt forms, designing prodrugs, and selecting assays (e.g., Caco-2, PAMPA, shake-flask). Key … Read more
