What are tablets made up of?

Tablets are mainly composed of active pharmaceutical ingredients (APIs) and excipients. The APIs are the therapeutic components that provide the desired medicinal effect, while excipients are inactive substances that aid in the manufacturing process, stability, and bioavailability of the tablet. Common excipients include binders, fillers, disintegrants, and lubricants, which help ensure the tablet's integrity and performance. They are typically compressed into a solid form, which can be coated for protection or to control the release of the medication.
