Dosage form refers to the physical form in which a medication is administered, such as tablets, capsules, injections, creams, or syrups. The choice of dosage form depends on factors such as the intended use of the medication, its chemical properties, and patient preference.

Tablets and capsules are the most common forms of medication as they are easy to use, transport, and store. Tablets are solid, compressed forms of medication that disintegrate in the stomach to release the active ingredient. Capsules are made up of a gelatin shell that contains the medication. They can be filled with a liquid, powder, or granules.

Creams, lotions, and ointments are applied topically to the skin for local effects. They are used for conditions such as skin rashes, itching, or inflammation. Transdermal patches are also used to deliver medication through the skin, which slowly releases the active ingredient into the bloodstream.

Injections are administered through various routes, including intravenous, intramuscular, and subcutaneous. They are usually used for medications that cannot be taken orally.

Syrups and suspensions are liquid forms of medication that can be swallowed. They are commonly used for children and adults who have difficulty swallowing tablets or capsules.

The dosage form can affect the absorption, distribution, and elimination of the medication in the body. Therefore, it is important to choose the appropriate dosage form for each individual patient to ensure safe and effective treatment.
