LECTURE OBJECTIVES
 To study an introduction of pharmacopoeias.
 To define pharmacopoeias as official books set by government authorities that establish quality
standards for drugs, ingredients, and pharmaceutical products.
 To understand the history of pharmacopoeias.
 To familiarize with the uniform standards through pharmacopoeias that helps to control adulterated
medicines and plays an important role in manufacturing, research, and export.
 To classify pharmacopoeias as either official, recognized by government agencies, or non-official

1
History of Pharmacopoeia
 The word Pharmacopoeia is derived from 2 Greek words ‘pharmakon’ = a drug and ‘poein’ = to
make or create.
 Pharmacopoeia is book containing directions for identification of samples and the preparation of
compound medicines, and published by the authority of a management or a medical or
pharmaceutical society.
History:
 Each country has some rules on pharmaceutical preparations which sets standards and required
quantity indices for medicament, raw materials and preparations employed in the manufacture of
drugs. These regulations are presented in separate articles.
 General and specific matters relating to individual drugs are published in the form of a book called a
Pharmacopoeia.
2
 On 15th
December 1820, the first United State Pharmacopoeia
(U.S.P) was released.
 In 1864, the first British Pharmacopoeia (B.P) was published with
monograph on benzoic acid, gallic acid, tartaric acid, tannic acid,
camphor, lactose, sucrose, and seven alkaloids along with their
salts.
History of Pharmacopoeia

Indian Pharmacopoeia (I.P.):
 Govt. of India constituted a permanent Indian Pharmacopoeia Committee in 1948 under the
chairmanship of Col. R. N. Chopra for the preparation of the Indian Pharmacopoeia and
established the central Indian Pharmacopoeia Laboratory at Ghaziabad, Uttar Pradesh to
keep up to date.
 Under the Drugs and Cosmetic Act, 1940, fulfill the requirements.
 The first edition of I.P. was published in the year 1955 under the chairmanship of Dr. B. N.
Ghosh.

Official Monograph:
 The monograph in a pharmacopoeia are the treaties on drug and formulations,
which give description, assay, assay limits and other details necessary for
maintaining requisite standards.
A monograph in I.P. includes the following.
1. Title: The main title for a drug substance is the International Non-proprietary
Name (INN) approved by WHO.
2. Chemical formulae: Chemical structure, molecular formulae and International
Union of Pure and Applied Chemists (IUPAC) name.

4. Definition: The opening statement of a monograph is definition of the substance.
5. Category: It express the pharmacological, therapeutic, pharmaceutical application of
the compound.
6. Dose: The average range of quantity which is suitable for adult.
7. Usual strength: Indicates the strength (s), information of pharmacists.

C.
10. Identification Test: IR absorption spectroscopy, UV, MP or BP, chemical test.
11. Limits: Designed for identify and control small quantities of impurities, which
are likely to be present in the substance.
12. Assay: Detail the analytical method for substance in order to determine
percentage content of a particular chemical in given test sample.

History of Pharmacopoeia
What are Impurities..........?
 Impurities may defined as a foreign matter or particle present in a compound.
Impurities in pharmaceuticals are the unwanted chemicals that remain with the
Active Pharmaceutical Ingredients (APIs) or develop during formulation or upon
aging of both API and formulated APIs to medicines. The presence of these
unwanted chemicals even in small amounts may influence the efficacy and safety
of the pharmaceutical products.
 Impurities can have unwanted pharmacological or toxicological effects that
seriously impact product quality and patient safety. The International Conference
on Harmonization (ICH) has formulated a workable guideline regarding the
control of impurities.
14
 According to ICH guidelines, an impurity in a drug substance is defined as-“any
component of a new drug substance or product that is not the drug substance or an
excipient.
There is an ever increasing interest in impurities present in APIs recently, not only purity
profile but also impurity profile has become essential as per various regulatory
requirements.
 The presence of the unwanted chemicals, even in small amount, may influence the
efficacy and safety of the pharmaceutical products.
 In the pharmaceutical world, an impurity is considered as any other organic material,
besides the drug substance, or ingredients, arise out of synthesis or unwanted chemicals
that remains with API’s.
What are Impurities..........?
15
 Effects of Impurities on Pharmaceuticals:
1. Some impurities if present beyond certain tolerance limits can cause untoward side effects that can
lead to unpleasant reactions.
2. Some impurities may be able to catalyse the degradation, thereby shortening the shelf life of the drug
substance.
3. Some impurities by their chemical nature can interact with the drug substance to affect its purity and
potency.
4. Some impurities by virtue of their unstable nature like hygroscopic nature, oxidisable nature etc., can
bring about change in the physical properties like appearance, taste, odour, stability, etc., of drug
causing technical difficulties in its use as well as formulation.
Source and Types of Impurities…
16
 Impurities may enter or are formed in a drug substance
during any of the following three stages:
1. During manufacturing.
2. During purification and processing.
3. During storage.
