A method for reducing the abuse potential of an oral dosage form of an opioid extractable by commonly available household solvents said method comprising combining a therapeutically effective amount of the opioid compound, or a salt thereof, a matrix-forming polymer and an ionic exchange resin.

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. Once or twice daily administration is possible. The matrix typically comprises PEO and the active substance is typically an opioid such as morphine or a glucuronide thereof.

The present invention relates to compositions for oral administration. The invention preferably comprises at least one abuse-resistant drug delivery composition for delivering a drug having potential for dose dumping in alcohol, related methods of preparing these dosage forms, and methods of treating a patient in need thereof comprising administering the inventive compositions to the patient. Most preferably, the dosage form includes verapamil. These formulations have reduced potential for abuse. In another formulation, preferably the abuse relevant drug is an opioid and the non-abuse relevant drug is acetaminophen or ibuprofen. More preferably, the opioid is hydrocodone, and the non-abuse relevant analgesic is acetaminophen. In certain preferred embodiments, the dosage forms are characterized by resistance to solvent extraction; tampering, crushing or grinding. Certain embodiments of the inventions provide dosage forms that provide an initial burst of release of drug followed by a prolonged period of controllable drug release.

The invention provides formulations that resist dose dumping in the presence of ethanol and methods of use thereof. The formulations can be used to prevent dose dumping, to increase safety of drugs, and to reduce abuse of drugs prone to such abuse. The formulations comprise at least one drug and a sustained release delivery system. In one embodiment, the drug is an opioid.

The invention relates to a dosing regimen for sedation with the fast-acting benzodiazepine CNS 7056 in combination with an opioid, in particular fentanyl, whereas CNS 7056 is given in a dose of 2 to 10 mg, preferably between 4 and 9 mg and most preferably between 5 and 8 mg.

The present invention relates to compounds of Formula I or II, or pharmaceutically acceptable salts, esters, or prodrugs thereof:

which relates to morphinan compounds useful as μ, δ, and/or κ receptor opioid compounds and pharmaceuticals containing same that may be useful for mediating analgesia, combating drug addiction, alcohol addiction, drug overdose, mental illness, bladder dysfunctions, neurogenic bladder, interstitial cystitis, urinary incontinence, premature ejaculation, inflammatory pain, peripherally mediated and neuropathic pain, cough, lung edema, diarrhea, cardiac disorders, cardioprotection, depression, and cognitive, respiratory, diarrhea, irritable bowel syndrome and gastro-intestinal disorders, immunomodulation, and anti-tumor agents.

The invention discloses a method which can carry out qualitative screening to 242 compounds (drugs or toxicants) simultaneously. A mode of liquid chromatogram-mass spectrometry (LC-MS/MS) multi-reaction monitoring (MRM) is adopted to carry out determinedness to objects by two pairs of parent ion-daughter ion pair and retention time. The 242 drugs or toxicants comprise toxic products such as opioids, amphetamine and cocaines and the like, bromazepam such as benzodiazepines and barbiturates, and common drugs, alkaloid, pesticide (including organophosphates, carbamates, pyrethroid pesticide residues and organochlorine pesticide), weed killer, raticide and the like.

A method for the treatment of Restless Leg Syndrome (RLS), which comprises administering an alpha2-agonist and a second agent selected from the group consisting of the dopamine agonists, opioids, benzodiazepines and the combination of L-DOPA plus a decarboxylase inhibitor.

Patients are treated with 24-hour oral sustained release opioid formulations which, upon administration, provide an initially rapid opioid absorption such that the minimum effective analgesic concentration of the opioid is more quickly achieved. These sustained release opioid formulations include an effective amount of at least one retardant material to cause said opioid analgesic to be released at a such a rate as to provide an analgesic effect after oral administration to a human patient for at least about 24 hours, and are characterized by providing an absorption half-life from 1 to about 8 hours. A method of titrating a human patient utilizing these sustained release opioid formulations is also disclosed.

The present invention relates to novel compounds that are A_2A adenosine receptor antagonists, and to their use in treating mammals for various disease states, such as obesity, CNS disorders, including the “movement disorders” (Parkinson's disease, Huntington's Chorea, and catelepsy), and cerebral ischemia, excitotoxicity, cognitive and physiological disorders, depression, ADHD, and drug addiction (alcohol, amphetamine, cannabinoids, cocaine, nicotine, and opioids) and to their use in the enhancement of immune response. The invention also relates to methods for the preparation of such compounds, and to pharmaceutical compositions containing them.

The topical medicament gel formulation of the present invention includes an anesthetic, an anti-microbial, an oxidant, a nutrient, a diuretic, an opioid, an anti-emetic, an anti-seizure drug, and a non-steroidal anti-inflammatory drug (NSAID), USP in a molecular, as opposed to a salt form, as the active ingredient. Additional constituents illustratively include a skin penetration enhancer and a gelling agent. This invention deals with problems commonly associated with topical application of local medicaments such as: slow onset of action; need for occlusion; and rapid loss of effect due to rapid systemic dispersion. The invention permits enhanced penetration of the medicament and thereby allows for a lesser total dosage of pharmaceutically active ingredient. The use of a lesser total dosage also decreases systemic toxicity.
