The chemical designation for lisdexamfetamine dimesylate is (2S)-2,6-diamino- N -[(1 S )-1-methyl-2-phenylethyl] hexanamide dimethanesulfonate. The molecular formula is C 15 H 25 N 3 O∙(CH 4 O 3 S) 2 , which corresponds to a molecular weight of 455.60. The chemical structure is: Lisdexamfetamine dimesylate is a white to off-white powder that is soluble in water (792 mg/mL). Lisdexamfetamine dimesylate capsules contain 10 mg, 20 mg, 30 mg, 40 mg, 50 mg, 60 mg, and 70 mg of lisdexamfetamine dimesylate (equivalent to 5.8 mg, 11.6 mg, 17.3 mg, 23.1 mg, 28.9 mg, 34.7 mg, and 40.5 mg of lisdexamfetamine). Inactive ingredients: colloidal silicon dioxide, croscarmellose sodium, magnesium stearate, and microcrystalline cellulose. The capsule shells (imprinted with RP##) contain gelatin, titanium dioxide, and one or more of the following: D&C Red #28, FD&C Blue #1, FD&C Red #3, FD&C Red #40, FD&C Yellow #6, Iron Oxide Black, Iron Oxide Red, and Iron Oxide Yellow. Additionally, the imprint ink contains the following non-volatile ingredients: shellac, black iron oxide, and potassium hydroxide. Chemical Structure

Methylphenidate hydrochloride extended-release capsules contain methylphenidate hydrochloride, a central nervous system (CNS) stimulant. Methylphenidate hydrochloride extended-release capsules contain multi layered beads, which are composed of an immediate-release layer which contains approximately 40% of the methylphenidate dose, and a controlled release layer which contains approximately 60% of the methylphenidate dose. Methylphenidate hydrochloride extended-release capsules are available in seven capsule strengths. Each extended-release capsule for once-a-day oral administration contains 10 mg, 15 mg, 20 mg, 30 mg, 40 mg, 50 mg, or 60 mg of methylphenidate HCl USP, which is equivalent to 8.6 mg, 13.0 mg, 17.3 mg, 25.9 mg, 34.6 mg, 43.2 mg, or 51.9 mg of methylphenidate free base, respectively. Chemically, methylphenidate HCl is d,l (racemic) methyl α-phenyl-2-piperidineacetate hydrochloride. Its molecular formula is C 14 H 19 NO 2 ∙HCl. Its structural formula is: Methylphenidate hydrochloride USP is a white to off-white, odorless, fine crystalline powder. Its solutions are acid to litmus. It is freely soluble in water and in methanol, soluble in alcohol, and slightly soluble in chloroform and in acetone. Its molecular weight is 269.77. Inactive Ingredients: ammonio methacrylate copolymer, type B; colloidal silicon dioxide (added if necessary); gelatin; hypromelloses; methacrylic acid copolymer, type C; polyethylene glycol; sugar spheres; talc; titanium oxide; and triethyl citrate.
