Pharmacokinetics (ADME): an overview

Introduction Pharmacokinetics is the branch of pharmacology devoted to understanding what the body does to a drug once it has been administered. This entails a detailed look at four main processes collectively known by the acronym ADME: Absorption, Distribution, Metabolism, and Excretion.

Over-the-Counter (OTC) Drugs in India: A Comprehensive Overview

Main Takeaway: India lacks a unified regulatory framework for OTC drugs, creating a complex landscape where medications not listed as prescription-only are sold over-the-counter. With 62.3% of urban populations practicing self-medication and an estimated market value of ₹188.6 billion, the CDSCO's upcoming 2025 OTC Drug Regulation represents a significant step toward establishing proper oversight and consumer safety. 1. Current Regulatory Status in India Absence of Unified OTC Framework Unlike Western countries, India currently lacks specific unifying regulations for OTC drugs. The term "OTC" has no legal recognition in Indian law. Instead, the regulatory approach follows a negative definition: drugs are considered OTC unless specifically listed as prescription-only medicines. Existing Drug Classification System Under the Drugs and Cosmetics Act, 1940 and Drugs and Cosmetics Rules, 1945, medications are categorized into different schedules: ScheduleDescriptionRequirementsSchedule HPrescription drugs"To be sold by retail only on prescription of a registered medical practitioner"Schedule H1Restricted prescription drugsStricter prescription requirementsSchedule XNarcotics and controlled substancesPrescription mandatorySchedule GCaution drugs (antihistamines)"Caution: it is dangerous to take this preparation except under medical supervision"Schedule KHousehold remediesCan be sold in villages with population below 1,000 Central Drugs Standard Control Organization (CDSCO) The Central Drugs Standard Control Organization (CDSCO), headed by the Drug Controller General of India (DCGI), serves as India's primary drug regulatory authority. CDSCO is responsible for: 2. The Upcoming 2025 OTC Drug Regulation Key Regulatory Changes The Over-the-Counter Drug Regulation India 2025 introduces several landmark changes: Schedule O Classification: Official categorization of OTC drugs into a new Schedule O Mandatory Labeling Requirements: Clear dosage instructions, warnings, and QR codes for consumer verification Advertising Restrictions: Ban on TV/radio advertisements for certain categories like antibiotics Online Sale Regulation: Only licensed platforms can sell OTC drugs with proper segregation from prescription medicines Approved OTC Medications Under 2025 Framework Drug CategoryApproved OTC MedicinesPain ReliefParacetamol, IbuprofenCold & FluCetirizine, ChlorpheniramineAntacids & DigestiveRanitidine, Antacid Gel, DigeneSkin CareCalamine lotion, Antifungal creamsVitamins & SupplementsVitamin C, B-complex, Iron tabletsOral RehydrationORS sachets, Electrolyte powders Important Exclusions: Antibiotics, steroids, and habit-forming drugs remain strictly excluded from OTC classification. 3.
