Artificially nalbuphine hydrochloride is 17-(cyclobutylmethyl)-4,5α-epoxymorphinan-3,6α,14-triol hydrochloride. Nalbuphine hydrochloride atomic weight is 393.91 and is dissolvable in H2o (35.5 mg/ml @ 25ºc) and ethanol (0.8%); insoluble in Chcl3 and ether. Nalbuphine hydrochloride has pka estimations of 8.71 and 9.96. The sub-atomic recipe is C21h27no4·hcl. NUBAIN is a sterile arrangement suitable for subcutaneous, intramuscular, or intravenous infusion. NUBAIN is accessible in two focuses, 10 mg and 20 mg of nalbuphine hydrochloride for every ml. Both qualities in 10 ml vials contain 0.94% sodium citrate hydrous, 1.26% citrus extract anhydrous, and 0.2% of a 9:1 mixture of methylparaben and propylparaben as additives; ph is balanced, if vital, to 3.5 to 3.7 with hydrochloric corrosive. The 10 mg/ml quality contains 0.2% sodium chloride. NUBAIN is likewise accessible in ampules in a sterile, without paraben definition in two fixations, 10 mg and 20 mg of nalbuphine hydrochloride for every ml. One ml of every quality contains 0.94% sodium citrate hydrous, and 1.26% citrus extract anhydrous; ph is balanced, if vital, to 3.5 to 3.7 with hydrochloric corrosive. The 10 mg/ml quality contains 0.2% sodium chloride.
