What is formulation in pharma?

Formulation in pharmaceuticals refers to the process of combining various chemical substances, including active pharmaceutical ingredients (APIs) and excipients, to create a final medicinal product that is safe, effective, and stable. This process involves optimizing the delivery method, dosage form (such as tablets, injections, or creams), and release characteristics to ensure the drug's therapeutic effects while minimizing side effects. Proper formulation is crucial for ensuring that the drug can be manufactured consistently and meets regulatory standards for quality and efficacy.
