Emtricitabine, rilpivirine and tenofovir disoproxil fumarate tablets are fixed-dose combination tablets containing FTC, rilpivirine hydrochloride, and TDF. Emtricitabine (FTC) is a synthetic nucleoside analog of cytidine. Rilpivirine (RPV) is a non-nucleoside reverse transcriptase inhibitor. Tenofovir disoproxil fumarate (TDF) is converted in vivo to tenofovir, an acyclic nucleoside phosphonate (nucleotide) analog of adenosine 5′-monophosphate. Emtricitabine, rilpivirine and tenofovir disoproxil fumarate tablets are for oral administration. Each tablet contains 200 mg of FTC, 27.5 mg of rilpivirine hydrochloride (equivalent to 25 mg of RPV), and 300 mg of TDF (equivalent to 245 mg of tenofovir disoproxil) as active ingredients. The tablets include the following inactive ingredients: corn starch, croscarmellose sodium, hypromellose, lactose monohydrate, magnesium stearate, microcrystalline cellulose, povidone, red iron oxide, talc, titanium dioxide, triacetin and yellow iron oxide. Emtricitabine: The chemical name of FTC is 4-Amino-5-fluoro-1-[(2R,5S)-2-(hydroxymethyl)-1,3-oxathiolan-5-yl]-2(1H)-pyrimidinone. Emtricitabine is the (-) enantiomer of a thio analog of cytidine, which differs from other cytidine analogs in that it has a fluorine in the 5-position. It has a molecular formula of C 8 H 10 FN 3 O 3 S and a molecular weight of 247.25. It has the following structural formula: FTC is a white to off-white powder with a solubility of approximately 112 mg per mL in water at 25°C. Rilpivirine : RPV is available as the hydrochloride salt. The chemical name for rilpivirine hydrochloride is 4-{[4-({4-[(E)-2-Cyanoethenyl]-2, 6-dimethylphenyl} amino) pyrimidin-2-yl] amino}benzonitrile. Hydrochloride. Its molecular formula is C 22 H 18 N 6 • HCl and its molecular weight is 402.9. Rilpivirine hydrochloride has the following structural formula: Rilpivirine hydrochloride is an off-white to yellow colored powder. Rilpivirine hydrochloride is practically insoluble in water over a wide pH range. Tenofovir DF: TDF is a fumaric acid salt of the bis-isopropoxycarbonyloxymethyl ester derivative of tenofovir. The chemical name of TDF is 9-[2-(R)-[[bis[[(isopropoxy carbonyl) oxy] methoxy]phosphinoyl]methoxy]propyl]-adenine fumaric acid (1:1). It has a molecular formula of C 19 H 3 0N 5 O 10 P • C 4 H 4 O 4 and a molecular weight of 635.51. It has the following structural formula: TDF is a white to off-white powder with a solubility of 13.4 mg per mL in water at 25°C. All dosages are expressed in terms of TDF except where otherwise noted. Emtricitabine Structural Formula Rilpivirine hydrochloride structural formula TDF structural formula
