10th Edition of The International Pharmacopoeia

The International Pharmacopoeia (Ph. Int.) contains recommended procedures for analysis and specifications for pharmaceutical substances (active pharmaceutical ingredients, APIs) and dosage forms. According to the WHO (World Health Organization) it is intended to serve as source for reference or adaptation by any WHO Member State. The Ph. Int. has legal status, whenever a national or regional authority refers to it in appropriate legislation.

Compared to other pharmacopoeias (e.g. Ph. Eur., USP, JP), "priority is given to medicines included in the WHO Model List of Essential Medicines and to medicines which are important for WHO health programmes and for which other pharmacopoeias do not offer any test specifications". Moreover, the needs of developing countries are taken into account.
