In pharmaceutics, a dosage form (DF) refers to the physical form of a dose of a chemical compound used as a drug or medication intended for administration or consumption. Dosage forms are pharmaceutical drug products that are marketed for use with a specific mixture of active ingredients and inactive components (excipients), in a particular configuration (such as a capsule shell, for example), and apportioned into a particular dose. Examples of dosage forms include tablets, capsules, powders, oral and injectable solutions, nasal sprays, creams, and ointments, among many others. The route of administration for drug delivery is dependent on the dosage form of the substance. Dosage forms can be designed to provide a particular release profile or sustained drug delivery. Depending on the context, multi(ple) unit dose can refer to distinct drug products packaged together, or to a single drug product containing multiple drugs and/or doses.
