Pharmaceutical Formulation Intermediates vs Active Pharmaceutical Ingredients – ZIM Labs

A Pharmaceutical Formulation Intermediate (or PFI) is a blend of active substances and excipients, oftentimes in a powdered form. An Active Pharmaceutical Ingredient (or API), on the other hand, is the active component of the drug that acts on the symptoms of a disease. APIs work in coordination with inactive ingredients, which have no direct effect in healing one’s health condition, but are necessary for its production.
