  • Publication number: 20160081946
    Abstract: A 4:3 naltrexone: 5-methyl-2-furaldehyde cocrystal and its use as an opioid antagonist are disclosed. The invention also relates to a drug-in-adhesive transdermal patch containing the analgesic fentanyl, a mu opioid agonist, or an analog thereof and a 4:3 naltrexone: 5-methyl-2-furaldehyde cocrystal, as an opioid antagonist. A transdermal patch of the invention is tamper-resistant and an abuse deterrent which protects against drug misuse or abuse. The invention also provides a method of treating pain, such as acute, chronic, or intermittent pain, by applying a drug-in-adhesive transdermal patch according to the invention to the skin of a patient in need thereof. Also disclosed is an improved transdermal patch for administering fentanyl or an analog thereof, or for administering a mu opioid agonist, the improvement wherein the transdermal patch contains a 4:3 naltrexone: 5-methyl-2-furaldehyde cocrystal in an abuse limiting amount.

  • Publication number: 20060052389
    Abstract: The invention generally relates to compositions and methods with tramadol and an opioid antagonist to enhance analgesic potency and/or attenuate one or more adverse effects of tramadol, including adverse side effect(s) in humans such as nausea, vomiting, dizziness, headache, sedation (somnolence) or pruritis. This invention relates to compositions and methods for selectively enhancing the analgesic potency of tramadol and simultaneously attenuating anti-analgesia, hyperalgesia, hyperexcitability, physical dependence and/or tolerance effects associated with the administration of tramadol. The methods of the present invention comprise administering to a subject an analgesic or subanalgesic amount of tramadol and an amount of excitatory opioid receptor antagonist such as naltrexone or nalmefene effective to enhance the analgesic potency of tramadol and attenuate the anti-analgesia, hyperalgesia, hyperexcitability, physical dependence and/or tolerance effects of tramadol.
