Pharmacopoeial Monographs

Pharmacopoeias are authoritative treatises on drugs and preparations presenting information on their description, formulation, analytic composition, physical constants, main chemical properties used in identification, standards for strength, purity, and dosage, chemical tests for determining identity and purity, etc.

The four major pharmacopoeias in use world-wide today are:

  1. The International Pharmacopoeia (IP) – “official” and primarily used in the developing nations
  2. The British Pharmacopoeia (BP) – “official” and primarily used in the 54 member countries of the British Commonwealth
  3. The United States Pharmacopoeia (USP) – “official” and primarily used in North America and in 27 other countries
  4. The European Pharmacopoeia (Ph. Eur.) – “official” and primarily used in the 26 countries which are member states of the Council of Europe

Tepnel offers testing from the four major pharmacopoeias listed above, BP, USP and Ph.Eur.  We also offer testing from the Japanese Pharmacopeia for testing specific to the Japanese marketplace.

With the implementation of the ICH Q6A document, guidance was given on the harmonisation of specifications such that there was a confluence of specifications across different regions. A consequence of the ICH6A document has been the subsequent harmonisation of several compendial test chapters among the USP, JP and EP.

Tepnel undertakes harmonised testing as per the ICH guidance for:
