AUSTEDO XR extended-release tablets and AUSTEDO tablets are formulated with deutetrabenazine, a vesicular monoamine transporter 2 (VMAT2) inhibitor for oral administration. The molecular weight of deutetrabenazine is 323.46; the pKa is 6.31. Deutetrabenazine is a hexahydro-dimethoxybenzoquinolizine derivative and has the following chemical name: ( RR, SS )-1, 3, 4, 6, 7, 11b-hexahydro-9, 10-di(methoxy-d 3 )-3-(2-methylpropyl)-2H-benzo[a]quinolizin-2-one. The molecular formula for deutetrabenazine is C 19 H 21 D 6 NO 3 . Deutetrabenazine is a racemic mixture containing the following structures: Deutetrabenazine is a white to slightly yellow crystalline powder that is sparingly soluble in water and soluble in ethanol. AUSTEDO XR AUSTEDO XR extended-release tablets contain 6 mg, 12 mg, 18 mg, 24 mg, 30 mg, 36 mg, 42 mg, or 48 mg deutetrabenazine, and the following inactive ingredients: ammonium hydroxide, black iron oxide, butyl alcohol, butylated hydroxyanisole, butylated hydroxytoluene, cellulose acetate, hydroxypropyl cellulose, hypromellose, isopropyl alcohol, magnesium stearate, polyethylene glycol, polyethylene glycol 3350, polyethylene oxide, polyvinyl alcohol, propylene glycol, shellac, sodium chloride, talc, titanium dioxide, and FD&C red #40 lake. The 6 mg, 12 mg, 18 mg, 30 mg, 36 mg, and 42 mg extended-release tablets also contain FD&C yellow #6 lake. The 6 mg, 12 mg, 24 mg, and 36 mg extended-release tablets also contain FD&C blue #2 lake. The 18 mg extended-release tablets also contain carmine. AUSTEDO XR Delivery System Components and Performance AUSTEDO XR uses osmotic pressure to deliver deutetrabenazine at a controlled rate. The delivery system, which resembles a round tablet in appearance, consists of a bilayer core tablet that contains deutetrabenazine along with other excipients. The biologically inert components of the tablet remain intact during gastrointestinal transit and are eliminated in the stool. AUSTEDO AUSTEDO tablets contain 6 mg, 9 mg, or 12 mg deutetrabenazine, and the following inactive ingredients: ammonium hydroxide, black iron oxide, butyl alcohol, butylated hydroxyanisole, butylated hydroxytoluene, magnesium stearate, mannitol, microcrystalline cellulose, polyethylene glycol, polyethylene oxide, polysorbate 80, polyvinyl alcohol, povidone, propylene glycol, shellac, talc, titanium dioxide, and FD&C blue #2 lake. The 6 mg tablets also contain FD&C red #40 lake. The 12 mg tablets also contain FD&C yellow #6 lake. chemical-structure.jpg

AZILECT ® tablets contain rasagiline (as the mesylate), a propargylamine-based drug indicated for the treatment of idiopathic Parkinson’s disease. Rasagiline mesylate is designated chemically as: 1H-Inden-1-amine, 2, 3-dihydro-N-2-propynyl-, (1R)-, methanesulfonate. The empirical formula of rasagiline mesylate is C 12 H 13 N•CH 4 SO 3 and its molecular weight is 267.34. Its structural formula is: Rasagiline mesylate is a white to off-white powder, freely soluble in water or ethanol and sparingly soluble in isopropanol. Each AZILECT tablet for oral administration contains 0.5 mg or 1 mg of rasagiline (equivalent to 0.78 mg or 1.56 mg of rasagiline mesylate). Each AZILECT tablet also contains the following inactive ingredients: mannitol, starch, pregelatinized starch, colloidal silicon dioxide, stearic acid, and talc. chemical structure

Glatiramer acetate, the active ingredient of COPAXONE, consists of the acetate salts of synthetic polypeptides, containing four naturally occurring amino acids: L-glutamic acid, L-alanine, L-tyrosine, and L-lysine with an average molar fraction of 0.141, 0.427, 0.095, and 0.338, respectively. The average molecular weight of glatiramer acetate is 5,000 – 9,000 daltons. Glatiramer acetate is identified by specific antibodies. Chemically, glatiramer acetate is designated L-glutamic acid polymer with L-alanine, L-lysine and L-tyrosine, acetate (salt). Its structural formula is: (Glu, Ala, Lys, Tyr) x ● x CH 3 COOH (C 5 H 9 NO 4 ●C 3 H 7 NO 2 ●C 6 H 14 N 2 O 2 ●C 9 H 11 NO 3 ) x ● x C 2 H 4 O 2 CAS - 147245-92-9 COPAXONE is a clear, colorless to slightly yellow, sterile, nonpyrogenic solution for subcutaneous injection. Each 1 mL of COPAXONE solution contains 20 mg or 40 mg of glatiramer acetate and the following inactive ingredient: 40 mg of mannitol. The pH of the solutions is approximately 5.5 to 7.0. The biological activity of glatiramer acetate is determined by its ability to block the induction of experimental autoimmune encephalomyelitis (EAE) in mice.
