Buprenorphine and naloxone sublingual film, 2 mg/0.5 mg, 4 mg/1 mg, 8 mg/2 mg and 12 mg/3 mg are rectangular orange film, which contains whitish particulates dispersed throughout the film and areas of lighter color, when observed against the aluminized side of the pouchstock material. The film is imprinted with “2”, “4”, “8” or “12” in blue ink as a strength identifier 2”, “4”, “8” or “12” may appear to be green in color). It contains buprenorphine HCl, a mu-opioid receptor partial agonist, and a kappa‐opioid receptor antagonist, and naloxone HCl dihydrate, an opioid antagonist, at a ratio of 4:1 (ratio of free bases). It is intended for sublingual or buccal administration and is available in four dosage strengths, 2 mg buprenorphine with 0.5 mg naloxone, 4 mg buprenorphine with 1 mg naloxone, 8 mg buprenorphine with 2 mg naloxone and 12 mg buprenorphine with 3 mg naloxone. Each film also contains acesulfame potassium, butylated hydroxyanisole, citric acid, FD&C yellow #6, lemon-lime flavor, maltitol, polyethylene oxide, povidone, sodium citrate and sodium metabisulfite. In addition, imprinting ink also contains ammonium hydroxide, FD&C Blue #1 and shellac. Chemically, buprenorphine HCl is (2S)-2-[17-Cyclopropylmethyl-4,5α-epoxy-3-hydroxy-6-methoxy-6α,14- ethano-14α-morphinan-7α-yl]-3,3-dimethylbutan-2-ol hydrochloride. It has the following chemical structure: Buprenorphine hydrochloride, USP has the molecular formula C 29 H 41 NO 4 •HCl and the molecular weight is 504.10 g/mol. It is a white or almost white crystalline powder, sparingly soluble in water, freely soluble in methanol, soluble in ethanol (96 percent), and practically insoluble in cyclohexane. Chemically, naloxone hydrochloride, USP dihydrate is 17-Allyl-4,5 α -epoxy-3, 14-dihydroxymorphinan-6-one hydrochloride dihydrate. It has the following chemical structure: Naloxone hydrochloride, USP dihydrate has the molecular formula C 19 H 21 NO 4 HCl•2H 2 O and the molecular weight is 399.87 g/mol. It is a white to off-white powder and is soluble in water, in dilute acids, and in strong alkali, soluble in alcohol, and practically insoluble in ether and chloroform. structurebuprenorpine.jpg structurenaloxone.jpg
