What does "dosage form" refer to in pharmacology?

In pharmacology, the term "dosage form" specifically refers to the physical form of a medication, which is essential for determining how the drug is administered and how it interacts with the body. This can include tablets, capsules, liquids, powders, and other formulations. Each dosage form has distinct characteristics that influence the drug's absorption, distribution, metabolism, and excretion. The choice of dosage form is crucial in ensuring the drug is effective, safe, and convenient for patient use.

While it is true that the way a medication is formulated for patient ingestion relates to dosage forms, this aspect alone does not encompass the full definition, as many formulations are not directly tied to interviews or usage by patients. Similarly, the method of drug delivery pertains to the broader process of how medications are administered, which can include various mechanisms beyond the intent defined by physical forms. Lastly, the quantity of active ingredients is an important aspect of medication, but it does not define the dosage form itself, as dosage forms can vary in strength and composition while still being categorized as the same form.
