What does pills have inside?

Pills typically contain active pharmaceutical ingredients (APIs) that provide the therapeutic effects, as well as inactive ingredients known as excipients. Excipients can include fillers, binders, preservatives, and colorants that help stabilize the formulation, aid in absorption, or improve the pill's appearance. The specific composition varies depending on the medication and its intended use. Always consult a healthcare professional or the medication's packaging for detailed information about a specific pill.
