Active pharmaceutical ingredients (APIs) represent the vital constituents within a pharmaceutical drug, exerting the necessary effects on the body to address specific conditions. These ingredients are derived through the processing of chemical compounds. In the context of biologic drugs, the active component is referred to as a bulk process intermediate (BPI).

Classification of Active Pharmaceutical Ingredients: 

APIs can be broadly categorized into two types – synthetic and natural. Synthetic APIs are further distinguished as innovative or generic, depending on the synthesis method employed.


Synthetic chemical APIs, also known as small molecules, constitute a significant portion of the pharmaceutical market, with numerous small molecule drugs commercially accessible.


Natural APIs find application in the production of biologics, which are increasingly emerging as top-selling drugs. Despite the growing demand, biologics currently lag behind small molecule drugs in terms of quantity.

APIs are further categorized based on their solubility into insoluble and soluble drugs.
