Medicinal formulations are combinations of active ingredients and excipients designed to deliver therapeutic effects. These formulations can take various forms, such as tablets, capsules, liquids, or topical creams, and are created to ensure the proper dosage, stability, and absorption of the medication. The process of developing medicinal formulations involves rigorous testing and quality control to ensure safety and efficacy. Regulatory bodies, like the Food and Drug Administration (FDA), oversee these formulations to ensure they meet specific standards before they can be prescribed or sold to the public.
