Varenicline tablets contain varenicline (as the tartrate salt), which is a partial nicotinic agonist selective for α 4 β 2 nicotinic acetylcholine receptor subtypes. Varenicline, as the tartrate salt of maltodextrin premix (1:1:10), is a powder which is a off-white to pinkish brown color with the following chemical name: 7,8,9,10-tetrahydro-6,10-methano-6 H -pyrazino[2,3- h][3]benzazepine, (2 R ,3 R )-2,3-dihydroxybutanedioate with maltodextrin (1:1:10). It is soluble in water, practically insoluble in acetone and methylene dichloride. Varenicline tartrate has a molecular weight of 361.35 Daltons and maltodextrin, and a molecular formula of C 13 H 13 N 3 • C 4 H 6 O 6 and maltodextrin. The chemical structure is: Varenicline tablets are supplied for oral administration in two strengths: a 0.5 mg circular, biconvex, white to off-white film-coated tablets, debossed with “P” on one side and “155” on other side and a 1 mg circular, biconvex, light blue film-coated tablets, debossed with “P” on one side and “156” on other side. Each 0.5 mg varenicline tablet contains 0.85 mg of varenicline tartrate equivalent to 0.5 mg of varenicline free base; each 1 mg varenicline tablet contains 1.71 mg of varenicline tartrate equivalent to 1 mg of varenicline free base. The following inactive ingredients are included in the tablets: croscarmellose sodium, maltodextrin, microcrystalline cellulose, stearic acid. The tablets are film-coated with a coating material containing hydroxypropyl cellulose, hypromellose, talc, and titanium dioxide.
