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, beta-hydroxy-3-methylfentanyl, levo-alpha-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.

A non-abusable, non-inflammatory, biocompatible, non-biodegradable, subcutaneous, polymeric implant for the prolonged, controlled release of hydromorphone with near zero-order kinetics is described. Methods of alleviating cancer pain and treating opioid drug addiction with the implant are also described.

The invention generally provides processes and intermediate compounds useful for the production of (+)-opiates. Non-limiting examples of (+) opiates that may be derived from one or more compounds of the invention include (+)-noroxymorphone, (+)-naltrexone, (+)-naloxone, (+)-N-cyclopropylmethylnorhydrocodone, (+)-N-cycloproylmethylnorhydromorphone, (+)-N-allylnorhydrocodone, (+)-N-allylnorhydromorphone, (+)-noroxycodone, (+)-naltrexol, (+)-naloxol, and (+)-3-O-methyl-naltrexone.

Disclosed herein are oral dosage forms of hydromorphone that are resistant to abuse and methods of their formulation. In particular, oral dosage forms that are resistant to dissolution in aqueous solutions of ethanol are described.

The invention provides a controlled-release composition comprising hydromorphone or a pharmaceutically acceptable form thereof in association with a gastro-resistant and ethanol-resistant compound and method of use thereof.

The present invention is direct to a method of producing analgesia in a mammalian subject. The method includes administering to the subject an omega conopeptide, preferably ziconotide, in combination with an analgesic selected from the group consisting of morphine, bupivicaine, clonidine, hydromorphone, baclofen, fentanyil, buprenorphine, and sufentanil, or its pharmaceutically acceptable salts thereof, wherein the ω-conopeptide retains its potency and is physically and chemically compatible with the analgesic compound. A preferred route of administration is intrathecal administration, particularly continuous intrathecal infusion. The present invention is also directed to a pharmaceutical formulation comprising an omega conopeptide, preferably ziconotide, in combination with an analgesic selected from the group consisting of morphine, bupivicaine, clonidine, hydromorphone, baclofen, fentanyl, buprenorphine, and sufentanil.

A pharmaceutical composition comprising an analgesic or analgesic combination and a stool softener is disclosed. The analgesic is selected from morphine, meperidine, fentanyl, hydromorphone, oxymorphone, oxycodone, hydrocodone, methadone, propoxyphene, pentazocine, levorphanol, codeine, acetaminophen and combinations of these analgesics. The composition is formulated for oral administration as a liquid or solid dosage form for immediate, slow, delayed or sustained-release characteristics.

A hydromorphone composition, a hydromorphone dosage form and a method for administering hydromorphone are disclosed, indicated for the management of pain.

The present invention relates to methods for reducing the risk associated with the administration of opioid analgesics in patients diagnosed or undiagnosed with respiratory illness by administering an analgesic composition comprising a sub-analgesic dosage of a μ-opioid agonist selected from the group consisting of morphine, fentanyl, sufentanil, alfentanil, oxymorphone and hydromorphone, or a pharmaceutically acceptable salt thereof, and a sub-analgesic dosage of oxycodone which is a κ₂-opioid agonist or a pharmaceutically acceptable salt thereof.

A method for the catalytic conversion of codeine, morphine or analogs thereof into hydrocodone, hydromorphone or analogs thereof utilizing a transition metal catalyst of the formula [M(PR³R⁴R⁵)_nX_m]_p; wherein R¹ is H, alkyl, aryl or acyl; M is a Group VIII transition metal; R³, R⁴ and R⁵ are selected from the group consisting of alkyl, aryl, alkoxyl, phenoxyl and combinations thereof; X is a halide or an anion; n is 1, 2, 3 or 4; m is 1 or 2; and p is at least 1.

One embodiment of the present invention is a method for reducing pain using a multi chamber pump to separately administer multiple drugs. For example, one chamber may contain an omega conopeptide, such as ziconotide, and the other chamber or chambers may contain one or more other drugs, which may include of morphine, hydromorphone, fentanyl, sufentanil, bupivacaine, baclofen, clonidine, and buprenorphine, or their pharmaceutically acceptable salts thereof. Other applications of the present invention include methods for treating severe chronic pain due to cancer, failed back syndrome, CRPS, neuropathic pain, mixed neuropathic and nociceptive pain.

A method for the catalytic conversion of codeine, morphine or analogs thereof into hydrocodone, hydromorphone or analogs thereof utilizing a transition metal complex of a tertiary phosphine halide as catalyst.
