Pharma APIs can be categorized into two primary types chemical APIs and biological APIs. Chemical APIs are typically synthesized through chemical processes in laboratories. These include small-molecule drugs, which are often small organic compounds designed for specific therapeutic effects. On the other hand, biological APIs, commonly referred to as biotech drugs, are derived from living organisms. They encompass a range of products such as monoclonal antibodies, peptides, and vaccines, which generally offer targeted therapies for complex diseases.
