bictegravir 30 MG / emtricitabine 120 MG / tenofovir alafenamide 15 MG Oral Tablet [Biktarvy]
What it is used for
BIKTARVY is indicated as a complete regimen for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in adults and pediatric patients weighing at least 14 kg: with no antiretroviral treatment history, or with an antiretroviral treatment history and not virologically suppressed, with no known or suspected substitutions associated with resistance to the integrase strand inhibitor class, emtricitabine, or tenofovir, or to replace the current antiretroviral regimen in those who are virologically-suppressed (HIV-1 RNA less than 50 copies per mL) on a stable antiretroviral regimen with no known or suspected substitutions associated with resistance to bictegravir or tenofovir. BIKTARVY is a three-drug combination of bictegravir (BIC), a human immunodeficiency virus type 1 (HIV-1) integrase strand transfer inhibitor (INSTI), and emtricitabine (FTC) and tenofovir alafenamide (TAF), both HIV-1 nucleoside analog reverse transcriptase inhibitors (NRTIs), and is indicated as a complete regimen for the treatment of HIV-1 infection in adults and pediatric patients weighing at least 14 kg: with no antiretroviral treatment history or with an antiretroviral treatment history and not virologically suppressed, with no known or suspected substitutions associated with resistance to the integrase strand inhibitor class, emtricitabine, or tenofovir, or to replace the current antiretroviral regimen in those who are virologically suppressed (HIV-1 RNA less than 50 copies per mL) on a stable antiretroviral regimen with no known or suspected substitutions associated with resistance to bictegravir or tenofovir.

Description
BIKTARVY (bictegravir, emtricitabine, and tenofovir alafenamide) is a fixed dose combination tablet containing bictegravir (BIC), emtricitabine (FTC), and tenofovir alafenamide (TAF) for oral administration. BIC is an integrase strand transfer inhibitor (INSTI). FTC, a synthetic nucleoside analog of cytidine, is an HIV nucleoside analog reverse transcriptase inhibitor (HIV NRTI). TAF, an HIV NRTI, is converted in vivo to tenofovir, an acyclic nucleoside phosphonate (nucleotide) analog of adenosine 5′-monophosphate. BIKTARVY tablets are available in two dose strengths: 50 mg/200 mg/25 mg tablet containing 50 mg of BIC (equivalent to 52.5 mg of bictegravir sodium), 200 mg of FTC, and 25 mg of TAF (equivalent to 28 mg of tenofovir alafenamide fumarate). 30 mg/120 mg/15 mg tablet containing 30 mg of BIC (equivalent to 31.5 mg of bictegravir sodium), 120 mg of FTC, and 15 mg of TAF (equivalent to 16.8 mg of tenofovir alafenamide fumarate). Both dose strengths of BIKTARVY tablets include the following inactive ingredients: croscarmellose sodium, magnesium stearate, and microcrystalline cellulose. The tablets for both dose strengths are film-coated with a coating material containing iron oxide black, iron oxide red, polyethylene glycol, polyvinyl alcohol, talc, and titanium dioxide. Bictegravir: The chemical name of bictegravir sodium is 2,5-Methanopyrido[1’,2’:4,5]pyrazino[2,1- b ][1,3]oxazepine-10-carboxamide, 2,3,4,5,7,9,13,13a-octahydro-8-hydroxy-7,9-dioxo- N -[(2,4,6-trifluorophenyl)methyl]-, sodium salt (1:1), (2 R,5 S,13a R )-. Bictegravir sodium has a molecular formula of C 21 H 17 F 3 N 3 NaO 5 and a molecular weight of 471.4 and has the following structural formula: Bictegravir sodium is an off-white to yellow solid with a solubility of 0.1 mg per mL in water at 20 °C. Chemical Structure Emtricitabine: The chemical name of FTC is 4-amino-5-fluoro-1-(2 R -hydroxymethyl-1,3-oxathiolan-5 S -yl)-(1H)-pyrimidin-2-one. 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. FTC has a molecular formula of C 8 H 10 FN 3 O 3 S and a molecular weight of 247.2 and 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. Chemical Structure Tenofovir alafenamide: The chemical name of tenofovir alafenamide fumarate drug substance is L-alanine, N -[( S )-[[(1 R )-2-(6-amino-9 H -purin-9-yl)-1-methylethoxy]methyl]phenoxyphosphinyl]-, 1-methylethyl ester, (2 E )-2-butenedioate (2:1). Tenofovir alafenamide fumarate has an empirical formula of C 21 H 29 O 5 N 6 P
½(C 4 H 4 O 4 ) and a formula weight of 534.5 and has the following structural formula: Tenofovir alafenamide fumarate is a white to off-white or tan powder with a solubility of 4.7 mg per mL in water at 20 °C. Chemical Structure
