FDC

FDC is an acronym that can refer to several terms across different fields, depending on context. Common uses include medicine, computing, and political organizations. Because the same initials may stand for multiple concepts, disambiguation is often necessary.

In pharmacology, fixed-dose combination (FDC) denotes a medicinal product that contains two or more active ingredients combined in a single dosage form. This design aims to improve patient adherence, simplify treatment regimens, and manage coexisting conditions. Examples include fixed-dose antiretroviral therapies for HIV, combination therapies for tuberculosis, and certain multi-drug cardiovascular regimens.

In computing, FDC stands for floppy disk controller, a hardware component that manages data transfer between a computer and a floppy disk drive. The FDC handles encoding, decoding, error checking, and timing, acting as an interface to the computer bus. With the decline of floppy drives, modern systems rarely include an FDC, though legacy machines and embedded systems may still use one.

In Ugandan politics, the Forum for Democratic Change (FDC) is a major opposition political party founded in 2004, advocating democratic reforms, governance, and civil liberties. The party participates in elections and public discourse, and is part of broader debates about constitutional reform and political participation in the country.

Beyond these, FDC may appear as an acronym for organizations, agencies, or project names in various regions. The intended meaning is typically inferred from the surrounding text or clarified by explicit definition.
