emtricitabine - Generic Medications

Emtricitabine (FTC) is a synthetic nucleoside analog with activity against human immunodeficiency virus type 1 (HIV-1) reverse transcriptase. The chemical name of FTC is 5-fluoro-1-(2 R ,5 S )-[2-(hydroxymethyl)-1,3-oxathiolan-5-yl]cytosine. 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 247.24. 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 25°C. The partition coefficient (log P) for FTC is −0.43 and the pKa is 2.65. Emtricitabine capsules are for oral administration. Each capsule contains 200 mg of FTC and the inactive ingredients: crospovidone, gelatin, magnesium stearate, microcrystalline cellulose, povidone, sodium lauryl sulphate, titanium dioxide and yellow iron oxide. The capsules are imprinted with edible ink containing black iron oxide, potassium hydroxide, propylene glycol, shellac and strong ammonia solution. Figure1
