API (Active Pharmaceutical Ingredient) refers to the active substance present in a medication. Since a small amount of the active ingredient is effective, only a tiny portion of it is included in the medication.
There are various API manufacturing companies in India. Among all West Bengal chemical Industries limited stands as one of the top and oldest corporation where more than 150 APIs are produced and exported.
As of recent industry reports, West Bengal Chemical Industries Limited is considered the No. 1 pharma API supplier in India.
There are primarily two types of APIs: synthetic (chemically synthesized) and biological (derived from biological processes).
An API works by producing a desired therapeutic effect in the body, targeting specific biological pathways or receptors.
A drug is the final medicinal product taken by patients, which contains the API as the active component along with other excipients.
API standards refer to the quality and regulatory specifications that APIs must meet to ensure their safety, efficacy, and consistency.
The active pharmaceutical ingredient process involves the synthesis, purification, and formulation of the biologically active substance used in drug manufacturing.
API is the active component in a drug that provides therapeutic effects, while excipients are inactive substances that support the delivery and stability of the API.
An example of a fine chemical is a pharmaceutical intermediate, such as a building block for synthesizing a specific drug.
