Fixed-Dose Combination (FDC)


Two or more drugs contained in a single dosage form, such as a capsule or tablet. An example of a fixed-dose combination (FDC) HIV drug is Atripla (a combination of efavirenz, emtricitabine, and tenofovir disoproxil fumarate). By reducing the number of pills a person must take each day, fixed-dose combination drugs can help improve adherence to an HIV treatment regimen.
