A composition comprising the tannate of an opioid. Suitable opioids include alfentanil, buprenorphine, butorphanol, carfentanil, cocaine, codeine, dezocine, diacetylmorphine, dihydrocodeine, dihydromorphine, diphenoxylate, diprenorphine, etorphine, fentanyl, heroin, hydrocodone, hydromorphone, &bgr;-hydroxy-3-methylfentanyl, levo-&agr;-acetylmethadol, levorphanol, lofentanil, meperidine, methadone, morphine, nalbuphine, nalmefene, o-methylnaltrexone, naloxone, naltrexone, oxycodone, oxymorphone, pentazocine, pethidine, propoxyphene, remifentanil, sufentanil, tilidine and tramadol. The opioid tannate may be readily prepared by reacting an opioid free base with tannic acid, either neat or in the presence of up to about 30 wt. % water, at a temperature of about 60 to about 150° C. and thereafter recovering the resultant opioid tannate. The opioid tannate may also be prepared by an alternative process that involves reacting the opioid free base with water at a temperature such that not more than about 10 wt. % of the opioid tannate will be decomposed and thereafter removing the water by freeze-drying.
一种包含阿片类药物丹宁酸盐的组合物。适用的阿片类药物包括阿芬太尼、布比诺夫因、布托啡诺、卡非太尼、可卡因、可待因、地佐辛、乙酰二氢吗啡、二氢可待因、二氢吗啡、地芬诺西拉特、地普诺啡、依托啡、芬太尼、海洛因、羟考酮、左旋-α-乙酰甲啡醇、左旋吗啡醇、洛芬太尼、哌替啶、美沙酮、吗啡、纳布啡林、纳尔美非那、邻甲基纳曲酮、纳洛酮、纳曲酮、羟考酮、羟吗啡、奈他唑辛、哌替啶、丙哌啶、雷米芬太尼、舒芬太尼、替利定和曲马多。阿片类药物丹宁酸盐可以通过将阿片类药物的自由碱与丹宁酸反应而轻松制备,反应可以在约60至约150°C的温度下在无水或含有约30重量%水的情况下进行,然后回收所得的阿片类药物丹宁酸盐。阿片类药物丹宁酸盐也可以通过另一种涉及将阿片类药物的自由碱与水反应的替代过程制备,反应温度使得不超过约10重量%的阿片类药物丹宁酸盐会分解,然后通过冷冻干燥去除水。
