Compendia
Compendia
Compendia are official reference books or collections that provide detailed information about drugs, medicines, and pharmaceutical substances. They include descriptions, standards, formulations, testing methods, and quality specifications. While pharmacopoeias are legally recognized standards for drug quality, compendia may also include additional scientific, clinical, or technical information about drugs and dosage forms. They serve as essential resources for pharmacists, manufacturers, and healthcare professionals to ensure safe, effective, and standardized use of medicines. Compendia often complement pharmacopoeias by providing extended guidance on newer drugs, excipients, and formulations.
Types of Compendia
Pharmacopoeial Compendia
- Official compendia recognized by law.
- Provide standards for identity, purity, strength, and quality of drugs.

Non-Pharmacopoeial or Private Compendia
- Published by scientific organizations, associations, or authors.
- Include additional information on drugs, formulations, clinical uses, and dosage forms.
- Example: Martindale: The Complete Drug Reference.
Formulary Compendia
- Focus on formulations and preparations of drugs rather than individual drug standards.
- Useful for pharmacists in hospital or community pharmacy settings.
- Example: Indian National Formulary (INF), British National Formulary (BNF).
Analytical Compendia
- Focus on methods of analysis and testing of drugs and excipients.
