SOVALDI (sofosbuvir) is a nucleotide analog inhibitor of HCV NS5B polymerase. The IUPAC name for sofosbuvir is ( S )-isopropyl 2-(( S )-(((2 R ,3 R ,4 R ,5 R )-5-(2,4-dioxo-3,4-dihydropyrimidin-1(2 H )-yl)-4-fluoro-3-hydroxy-4-methyltetrahydrofuran-2-yl)methoxy)-(phenoxy)phosphorylamino)propanoate. It has a molecular formula of C 22 H 29 FN 3 O 9 P and a molecular weight of 529.45. It has the following structural formula: Sofosbuvir is a white to off-white crystalline solid with a solubility of ≥ 2 mg/mL across the pH range of 2–7.7 at 37 °C and is slightly soluble in water. SOVALDI tablets, 200 mg or 400 mg, are for oral administration. Each tablet contains 200 mg or 400 mg of sofosbuvir. The tablets include the following inactive ingredients: colloidal silicon dioxide, croscarmellose sodium, magnesium stearate, mannitol, and microcrystalline cellulose. The tablets are film-coated with a coating material containing the following inactive ingredients: polyethylene glycol, polyvinyl alcohol, talc, titanium dioxide, and yellow iron oxide. SOVALDI pellets, 150 mg or 200 mg, are for oral administration, supplied as white to off-white pellets in unit-dose packets. Each unit-dose packet contains 150 mg or 200 mg of sofosbuvir. The pellets include the following inactive ingredients: amino methacrylate copolymer, colloidal silicon dioxide, croscarmellose sodium, hydroxypropyl cellulose, hypromellose, lactose monohydrate, microcrystalline cellulose, polyethylene glycol, silicon dioxide, sodium lauryl sulfate, sodium stearyl fumarate, stearic acid, and talc.
