Drug formulation is the process of combining various chemical substances to create a medication that is safe and effective for patients. This involves selecting the right ingredients, such as active pharmaceutical ingredients (APIs) and excipients, which help in the drug's stability, absorption, and delivery. The goal is to ensure that the drug can be easily administered and absorbed by the body. The formulation process also considers factors like dosage form, which can include tablets, capsules, or liquids. Each form has its own advantages and challenges, influencing how the drug is released and how quickly it acts. Proper formulation is crucial for achieving the desired therapeutic effect while minimizing side effects.
