The letters after a medicine's name show which pharmacopoeia (an official book of quality standards) the maker says the medicine is made to meet. IP means the Indian Pharmacopoeia, BP the British Pharmacopoeia and USP the United States Pharmacopeia. They name a rulebook, not a brand, a dose or a ranking.
This page is general information about medicine labels, not medical advice. If you manufacture or buy chemicals for pharmaceutical use, read the IP, BP and USP grade guide for manufacturers instead.
What are the full forms of IP, BP and USP?
Each set of letters is the short name of a pharmacopoeia. A pharmacopoeia is an official book of quality standards: for each substance or medicine it lists, it describes the tests to run and the limits to stay within. Different countries and regions publish their own; these are the main ones.
| Letters | Full form | Country or region | Published by |
|---|---|---|---|
| IP | Indian Pharmacopoeia | India | Indian Pharmacopoeia Commission (IPC), Ghaziabad |
| BP | British Pharmacopoeia | United Kingdom | British Pharmacopoeia Commission, whose secretariat is part of the Medicines and Healthcare products Regulatory Agency (MHRA) |
| USP | United States Pharmacopeia | United States | United States Pharmacopeial Convention |
| NF | National Formulary | United States | Published together with USP, as USP–NF |
| Ph. Eur. | European Pharmacopoeia | Europe | European Directorate for the Quality of Medicines (EDQM) |
| JP | Japanese Pharmacopoeia | Japan | Ministry of Health, Labour and Welfare |
Labels sometimes print the letters with full stops, as I.P. or B.P. The meaning is the same. BP can also stand for blood pressure, but after a medicine's name it means the British Pharmacopoeia.
Why does it say IP on medicines sold in India?
IP is India's own pharmacopoeia. Under the Second Schedule of the Drugs and Cosmetics Act, 1940, the Indian Pharmacopoeia is the official book of standards for drugs in India, and its standards are legally enforceable. That describes its legal status in India; it is not a ranking of IP against BP or USP. The Indian Pharmacopoeia Commission in Ghaziabad publishes it.
So when the label of a medicine made for the Indian market carries IP after the name, it points to that national book. The maker is stating the standard the medicine is made to meet. The suffix is shorthand for that one statement. It does not describe the brand, the strength or the company.
You may also see BP or USP on a medicine sold in India. That means the maker named a different book. The letters tell you which book was named, not why.
What does the year after BP or IP mean?
Pharmacopoeias are revised, so each book comes in editions, and the year names the edition, much as a textbook does. The current position:
- IP 2026 is the 10th edition of the Indian Pharmacopoeia, released on 2 January 2026. It has 3,340 monographs, 121 of them new. It supersedes IP 2022, although an IP 2022 monograph that IP 2026 does not carry remains official.
- BP 2026 has been legally in force since 1 January 2026. BP 2027 has been available since 1 August 2026 and takes legal effect on 1 January 2027.
- USP–NF no longer has one yearly edition. Since July 2025 it is published online as six issues a year, and each document carries its own official date. There is no single "USP 2026", so USP is cited by the date of the individual monograph.
A year on a label names an edition. It does not say whether the medicine is good or poor, and editions are replaced over time.
Is IP, BP or USP better?
No. The three are separate rulebooks from separate places, not grades on one scale, and the letters are not a quality ranking. Each says "made to meet this book". A pharmacopoeia sets the tests and the limits. Whether a particular batch meets them depends on the maker, not on which book was named.
Some texts are shared between pharmacopoeias. The Pharmacopoeial Discussion Group (PDG) brings together the European, Japanese and United States pharmacopoeias and the Indian Pharmacopoeia Commission, whose full membership was announced on 5 October 2023. Through it, selected texts are harmonised. IP 2026 has 18 general chapters and 22 excipient monographs (excipients are the non-active ingredients in a medicine) that are harmonised with PDG texts. Harmonised means the same results and the same accept-or-reject decision. It does not mean identical legal status or timing in every country, and it covers selected texts, not whole books.
Is a USP medicine different from an IP one?
The idea is the same; the book is different. A medicine marked IP is made to meet the Indian Pharmacopoeia. A medicine marked USP is made to meet the United States Pharmacopeia. The same applies to a tablet marked BP or a syrup marked USP or BP: the letters name the book, not the form of the medicine.
Each book has its own entry, called a monograph, for a substance or product. Where a text is harmonised, two books agree on the results and the accept-or-reject decision. Where it is not, the two entries are separate documents and may differ in detail, such as test methods or limits.
So a USP medicine is not a stronger, weaker, newer or older version of an IP one. It is a medicine whose maker has named a different book.
What the letters do not tell you
IP, BP and USP are short, which makes them easy to over-read. The letters do not tell you:
- whether the medicine is right for you, or what it is for;
- the dose or strength, or how the medicine should be taken;
- whether it suits a child, pregnancy or other medicines you take;
- whether one brand is better than another;
- where the medicine was made;
- which edition of the book applies, unless a year is shown.
Read the letters as one line of information: this is the book the maker names. Everything else on the pack, and everything about your own health, sits outside it. The letters point to a book, which is useful to a pharmacist or a student, but they are not a verdict.
If you have a question about a specific medicine, ask your pharmacist or doctor.
For manufacturers and buyers
If you are buying chemicals for pharmaceutical, food or other regulated use rather than reading a medicine label, the questions change: which standard goes on the specification, which edition, and what the certificate of analysis must state. Start here:
- IP vs BP vs USP grade chemicals: which pharmacopoeial grade to specify.
- What "USP grade" means for a chemical, and how USP, NF, FCC and ACS differ.
- DEG and EG testing of glycerine, propylene glycol, sorbitol and PEG: excipient safety testing.
Supreme Petro Chemicals is a chemical trader in Chennai supplying raw materials to manufacturers, including chemicals in pharmacopoeial grades such as IP, BP and USP. We are not a pharmacy and we do not sell medicines to the public.
FAQ
What is the full form of IP in pharmacy?
IP stands for Indian Pharmacopoeia. It is India's official book of standards for drugs, published by the Indian Pharmacopoeia Commission in Ghaziabad, and under the Second Schedule of the Drugs and Cosmetics Act, 1940 its standards are legally enforceable. After a medicine's name, IP shows the book the medicine is made to meet.
What does IP mean on a tablet strip?
It means the maker states that the tablet is made to meet the Indian Pharmacopoeia. The letters name a standard. They do not state the strength, the brand, the place of manufacture or whether the tablet suits you. A year after the letters, such as IP 2026, names the edition of the book.
What is the difference between IP and BP in medicine?
IP is the Indian Pharmacopoeia, published by the Indian Pharmacopoeia Commission. BP is the British Pharmacopoeia, produced by the British Pharmacopoeia Commission, whose secretariat is part of the UK's Medicines and Healthcare products Regulatory Agency (MHRA). They are separate books for different countries, and neither is a quality ranking. The editions to know are IP 2026, released on 2 January 2026, and BP 2026, in force from 1 January 2026 (BP 2027 follows on 1 January 2027).
What does USP mean on a syrup or tablet?
USP stands for United States Pharmacopeia, published by the United States Pharmacopeial Convention. On a syrup or a tablet it shows the book the medicine is made to meet, in the same way IP or BP do. It is a different book from IP and BP, not a higher or lower grade.
What does BP mean on a medicine label?
BP means the British Pharmacopoeia, produced in the United Kingdom by the British Pharmacopoeia Commission, whose secretariat is part of the MHRA. After a medicine's name it does not mean blood pressure. BP 2026 has been in force since 1 January 2026, and BP 2027 takes effect on 1 January 2027.
Does IP mean the medicine is made in India?
No. IP shows the standard, not where the medicine was made. It is India's own pharmacopoeia, but the letters are not a country-of-origin mark, and a label that names BP or USP is naming a different book, not saying where the medicine was made.
