Drug formulation refers to the process of creating a dosage form that is suitable for administering a particular drug to patients. This involves selecting and combining an appropriate drug with other substances, such as excipients or diluents, to create a final product that can be easily and effectively used by patients. The goal of drug formulation is to ensure the drug's efficacy, safety, and stability while also considering factors like patient compliance, dosing accuracy, and ease of administration. Drug formulations are essential for delivering medications in the correct manner and ensuring that they work as intended when taken by patients.
