Raw materials for bulk drugs are called Active Pharmaceutical Ingredients (API). APIs are chemical compounds that are important for manufacturing medicines. API produces the desired results in the treatment of diseases. Chemically active APIs, which are the active ingredients in a medicine, are packaged together with chemically inactive excipients, which deliver API effects to the system. The raw materials for the production of API do not depend on only one chemical reaction; multiple chemical reactions are required. Intermediates are chemical compounds that are in the process of becoming APIs from raw materials. Our company supplies Drotaverine API, Mebeverine API and many other pharmaceutical APIs.
