  • Publication number: 20150080422
    Abstract: Methods and compositions are provided for preventing or reversing loss of the therapeutic effect of a drug, where the loss is associated with the repeated administration of the drug to a patient. The method includes administering to the patient a dopamine receptor agonist or partial agonist or a drug that increases the extracellular level of dopamine by enhancing release of dopamine, decreasing the removal of dopamine from the extracellular space, enhancing the synthesis of dopamine within the brain, or decreasing metabolic degradation of dopamine; and also administering to the patient an opioid receptor antagonist in an ultra-low dose amount, wherein the ultra-low dose amount is effective to prevent or reverse loss of therapeutic effects associated with the repeated administration of the drug to the patient. The methods are useful for various treatments, including treating Parkinson's Disease, Restless Leg Syndrome, depression, schizophrenia, psychostimulant drug abuse, or attention deficit disorder.

  • Publication number: 20150079150
    Abstract: A composition for controlled release of an opioid from a pharmaceutical composition, the method comprises controlling the release of at least one opioid into an aqueous medium by erosion of at least one surface of a pharmaceutical composition comprising I) a matrix composition comprising a) polymer or a mixture of polymers, b) an opioid and, optionally, c) one or more pharmaceutically acceptable excipients, and (i) a coating. The matrix composition has a conus-like shape so the surface area exposed to the aqueous medium increases at least during initial erosion of the matrix composition, and the dissolution of the opioid-when tested in a Dissolution Test as described herein with or without application of sinkers-results in a zero order release of at least 80% of the opioid contained in the composition. Such compositions are especially suitable for controlled release of an opioid to obtain a delayed pead concentration and a prolonged therapeutically effective plasma concentration upon oral administration.

  • Publication number: 20150045383
    Abstract: An extended release composition for an analgesic active pharmaceutical ingredient which may be an opioid, preferably hydrocodone as the only active ingredient. The extended release composition preferably comprises a extended release composition which may be in the form of beads contained in an oral dosage form such as gelatin capsules. The composition is designed to release hydrocodone in a way such that the increase in hydrocodone exposure in hepatically impaired patients is not clinically significant. The oral dosage units are supplied as part of a kit, which also includes a primary package and a package insert all sold as a commercially marketed product.
