Efavirenz, emtricitabine and tenofovir disoproxil fumarate is a fixed-dose combination tablet containing EFV, FTC, and TDF. EFV is a non-nucleoside reverse transcriptase inhibitor (NNRTI). FTC is a synthetic nucleoside analog of cytidine. TDF, which is converted in vivo to tenofovir, is an acyclic nucleoside phosphonate (nucleotide) analog of adenosine 5′-monophosphate. Efavirenz, emtricitabine and tenofovir disoproxil fumarate tablets are for oral administration. Each tablet contains 600 mg of EFV, 200 mg of FTC, and 300 mg of TDF (equivalent to 245 mg of tenofovir disoproxil) as active ingredients. The tablets include the following inactive ingredients: croscarmellose sodium, hydroxypropyl cellulose, magnesium stearate, microcrystalline cellulose, and sodium lauryl sulfate. The tablets are film-coated with a coating material containing polyethylene glycol, polyvinyl alcohol, talc, and titanium dioxide. Efavirenz: EFV is chemically described as ( S )-6-chloro-4-(cyclopropylethynyl)-1,4-dihydro-4-(trifluoromethyl)-2 H -3,1-benzoxazin-2-one. Its molecular formula is C 14 H 9 ClF 3 NO 2 and its structural formula is: Efavirenz USP is a white to off-white, crystalline powder with a molecular mass of 315.68. It is practically insoluble in water (less than 10 mcg/mL). Emtricitabine: The chemical name of FTC is 5-fluoro-1-(2 R ,5 S )-[2-(hydroxymethyl)-1,3-oxathiolan-5-yl]cytosine. FTC 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 247.24. It has the following structural formula: Emtricitabine is a white to off-white powder with a solubility of approximately 112 mg/mL in water at 25ºC. Tenofovir DF: TDF is a fumaric acid salt of the bis -isopropoxycarbonyloxymethyl ester derivative of tenofovir. The chemical name of TDF is 9-[( R )-2[[bis[[(isopropoxycarbonyl)oxy]-methoxy]phosphinyl]methoxy]propyl]adenine fumarate (1:1). It has a molecular formula of C 19 H 30 N 5 O 10 P • C 4 H 4 O 4 and a molecular weight of 635.52. It has the following structural formula: TDF is a white to off-white crystalline powder with a solubility of 13.4 mg/mL in water at 25°C.
