fixed-combination drug
Definition
- Noun:
- A fixed-combination drug is a pharmaceutical preparation that contains two or more active medicinal ingredients combined together in specific, unvarying amounts within a single dosage form, such as a tablet, capsule, or liquid.
Usage
- The term fixed-combination drug is used to describe a specific type of medication. It emphasizes that the ratio of the ingredients is constant and cannot be adjusted independently by the prescriber or patient.

Examples
