India and Pharmacy Education: Chapter: 11

Continued....... India and Pharmacy Education: Chapter: 10

Dear Readers, with the beginning of the first edition this year, I shall take up a new subject in pharmaceutics. This is my expertise as well.

I shall briefly mention one by one the topics which are studied under this subject in different years of under graduation. B. Pharmacy 1st year has a subject called Pharmaceutics-I.

Starting with the subject, knowledge about pharmacopeia is given. What information do they contain? How did they evolve? The Indian Pharmacopeia is an official book.

It is a collection of legal documents established by a national or regional body concerning standards and quality criteria for medications used in the country or region.

It consists of suitable tests that confirm the identity and purity of the product and determine its strength.

Dosage forms

Dosage forms: An introduction to the various dosage forms is given. Dosage forms are the carriers thru which drugs are delivered to sites of action within the body.

Students learn about the different dosage forms existing in the market such as tablets, capsules, pills, dusting powders, granules.

Liquid dosage forms: Liquid dosage form can be monophasic or biphasic.

Monophasic: It includes syrups, solutions, liniments, lotions, mouthwashes, gargles, inhalations.

Biphasic: It suspensions and emulsions. Semisolids dosage form include mostly external use preparations such as ointments, creams and pastes.

They learn their formulation, packaging and labeling as well in the practical classes.

Posology: Another important topic learnt in these basics is posology. It is defined as the branch of science that deals with the dose or quantity of drugs that can be administered to a patient to achieve the desired therapeutic effect.

The different factors affecting the dose of patient are age, sex, body weight, route and time  of administration.

Other factors which also influence drug effects are environmental factors, emotional factors, changes in metabolic disturbances, presence of other diseases.  

Drugs may have additive effects, synergism, antagonism, tolerance  and interactions between them or with food as well. 

We shall proceed with other topics in pharmaceutics—I in successive chapters.
