Definition

A dosage form that contains one or more active and/or inactive ingredients. Drug products come in many dosage forms, including tablets, capsules, liquids, creams, and patches. They can also be given in different ways, such as by mouth, by infusion into a vein, or by drops that are put into the ear or eye. The form with the active ingredient is used to prevent, diagnose, treat, or relieve symptoms of a disease or abnormal condition. A drug product that does not contain an active ingredient and is used in research studies is called a placebo. Also called medication.
