Active pharmaceutical ingredients (APIs) are biologically active components in pharmaceutical drugs, responsible for the intended therapeutic effects. APIs are prepared through chemical synthesis or biotechnology, meeting stringent quality standards and regulatory requirements. We maintain a professional attitude and ensures the effectiveness and safety of our APIs product. APIs combine with excipients to create different dosage forms. In general, APIs play a pivotal role in drug therapy, benefiting patients worldwide through enhanced therapeutic efficacy and improved treatments.

As a professional API global leader, Protheragen provides a full range of pharmaceutical active ingredients to meet the needs of different customers, including but not limited to small molecules, proteins, peptides, nucleic acids, enzymes, etc.
