Drug Schedules under the Drugs & Cosmetics Act

Statutory architecture & scope

• The parent statute — the Drugs Act, 1940 controls the manufacture, sale & distribution of drugs in India; a 1962 amendment added cosmetics, renaming it the Drugs & Cosmetics (D&C) Act, and it now covers Allopathic, Ayurvedic, Unani, Siddha & Homoeopathic drugs.
• Two-tier legal structure — the D&C Act, 1940 (parent legislation, passed by Parliament) is operationalised by the D&C Rules, 1945 (delegated/subordinate legislation). Most schedules are appended to the Rules, not the Act — so they can be revised by the central government by gazette notification without re-legislating.
• What a "Schedule" is — an annexure to the Rules that groups drugs (or other items) sharing a common regulatory treatment, and prescribes the labelling, prescription, sale, storage & record-keeping obligations that attach to that group.
• Schedules to the Act vs the Rules — the Act itself carries only two — the First Schedule (authoritative ASU formulary books) and Second Schedule (standards of quality). The Rules carry the long alphabetical run A → Y (with sub-schedules C1, F1, M-I/II/III, P-I) governing every facet of the drug life-cycle.
• Topic scope — "drug schedules" here means the Indian D&C Act/Rules schedule system (labelling/prescription/storage) — not the global controlled-substance "scheduling" of the US Controlled Substances Act or the NDPS Act lists (the NDPS Act is a separate statute the D&C schedules only cross-reference).
• Regulators — the Central Drugs Standard Control Organisation (CDSCO), headed by the Drugs Controller General of India (DCGI), is the central authority (new-drug approval, trial permission, imports, Schedule C/C1 & X oversight); State Drug Control Authorities license manufacture and retail/wholesale sale.
