Combination drugs are medications that contain two or more active ingredients in a single dosage form. They are often used to treat conditions that require multiple therapeutic effects, such as hypertension or diabetes. By combining different drugs, healthcare providers can simplify treatment regimens, improve patient adherence, and enhance overall effectiveness. These drugs can work in various ways, such as targeting different pathways in the body or reducing side effects associated with higher doses of a single medication. Common examples include antibiotics that combine multiple agents to combat infections and pain relievers that blend ingredients for better pain management.
