Pharmaceutical 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 delivery and stability of the drug. The goal is to ensure that the medication 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. Additionally, it involves rigorous testing to ensure that the final product meets quality standards and regulatory requirements, ensuring patient safety and efficacy.
