Fixed Dose Combination

What is FDO?

A Fixed Dose Combination (FDO) is a pharmaceutical formulation that combines two or more active drug ingredients in a fixed ratio within a single dosage form, such as a tablet or capsule. In India, FDOs are widely used to simplify treatment regimens, improve patient compliance, and enhance therapeutic efficacy, especially in managing chronic conditions like diabetes, hypertension, and tuberculosis. The Drug Controller General of India (DCGI) strictly regulates FDOs, requiring manufacturers to justify the rationale behind combining drugs, as many irrational combinations have been banned due to safety concerns. FDOs are commonly prescribed in both public health programs and private practice, and they feature prominently in discussions on rational drug use. For students preparing for NEET PG, GPAT, or pharmacy exams, understanding FDOs is essential because questions often test knowledge of approved combinations, their indications, and regulatory guidelines from the Indian Pharmacopoeia and DCGI circulars. The use of FDOs also raises issues in pharmacovigilance, as adverse drug reactions can be difficult to attribute to a single component. Overall, FDOs represent a balance between convenience and safety in Indian healthcare.
