What is Pharmaceutical Drug Substance / API (Active Pharmaceutical
Ingredient) And Pharmaceutical Drug Products?
This article is for understanding what is Pharmaceutical drug substance
/ Active Pharmaceutical ingredients (API) and drug product. These are two different
terms that can be easily understood by the picture depicting above. Drug
Substance i.e. API (Active Pharmaceutical Ingredient) is the Start point for
the manufacturing of any medicine which results the manufacturing of end
product i.e. Drug Product.

What is Definition of Drug substance (API)?
“An active pharmaceutical ingredient (API) is a substance which is used in the preparation of a drug product.
API and excipients (inert materials)
together form a drug product which is used for the treatment of diseases in
human beings. The API is also called as a drug substance.”

ICH definition of an Active Pharmaceutical
Ingredient (API)
Any
substance or mixture of substances intended to be used in the manufacture of a
drug (medicinal) product and that, when used in the production of a drug,
becomes an active ingredient of the drug product. Such substances are intended
to furnish pharmacological activity or other direct effect in the diagnosis,
cure, mitigation, treatment, or prevention of disease or to affect the
structure and function of the body.

US FDA definition of an Active Pharmaceutical
Ingredient (API)
“Active
Pharmaceutical Ingredient (API) (or Drug Substance): Any substance or mixture
of substances intended to be used in the manufacture of a drug (medicinal)
product and that, when used in the production of a drug, becomes an active
ingredient of the drug product. Such substances are intended to furnish
pharmacological activity or other direct effect in the diagnosis, cure,

Active
Pharmaceutical Ingredient (API) (or Drug Substance) are the substances those
are responsible for the activity of medicines.

Types of API?
High
Potent Active Pharmaceutical Ingredients (API)
An inbuilt
capacity of a drug substance to stimulate biological activity at a given amount
is the Potency. At very low concentration, micrograms (µg) these APIs will show
very high intensity of drug action. Hence, on OELs in µg/m3 (OQL = occupational exposure limit) has been selected for the establishment of the
potency of the highly potent active pharmaceutical ingredients. Lower the
value, the higher the potency of the compound. High Potent APIs are
specifically used for the treatment of cancer. Some good examples are listed
below.

Non-Potent
Active Pharmaceutical Ingredients (API)
These
APIs do not have inherent capacity to stimulate biological activity at at a low
concentration level of micrograms (µg). These APIs have low potency and their
very low dose level does not alter the human beings DNA. Low potent APIs are
used for the treatment of various diseases in human beings and animals. Below
are some Common API lay in this category.

substance, generally but not necessarily in association with one or more other ingredients”
