Disclosed in certain embodiments is an oral dosage form comprising: a therapeutically effective amount of an opioid analgesic; an opioid antagonist; and an irritant in an effective amount to impart an irritating sensation to an abuser upon administration of the dosage form after tampering.

Disclosed in certain embodiments is an oral dosage form comprising a therapeutically effective amount of an opioid analgesic; an opioid antagonist; and a bittering agent in an effective amount to impart a bitter taste to an abuser upon administration of the dosage form after tampering.

Sustained release dosage forms for twice daily oral dosing to a human patient for providing relief from pain are provided. The sustained release dosage form comprises an immediate release component and a sustained release component, wherein the immediate release component and the sustained release component collectively contain a therapeutically effective amount of an opioid analgesic and a therapeutically effective amount of nonopioid analgesic. In a preferred embodiment, the nonopioid analgesic is acetaminophen and the opioid analgesic is hydrocodone and pharmaceutically acceptable salts thereof, and in preferred embodiments, the pharmaceutically acceptable salt is bitartrate. The dosage forms produce plasma profiles in a patient characterized by a Cmax for hydrocodone of between about 0.6 ng / mL / mg to about 1.4 ng / mL / mg and an AUC for hydrocodone of between about 9.1 ng*hr / mL / mg to about 19.9 ng*hr / mL / mg (per mg hydrocodone bitartrate administered) and a Cmax for acetaminophen of between about 2.8 ng / mL / mg and 7.9 ng / mL / mg and an AUC for acetaminophen of between about 28.6 ng*hr / mL / mg and about 59.1 ng*hr / mL / mg (per mg acetaminophen administered) after a single dose.

The present invention relates to methods and compositions for reducing Distress Dysfunction by restoring and maintaining homeostatic balance in the neurotransmitter systems underlying the Stress Response and the experience of distress and hedonic tone. Distress Dysfunction refers to the experience of dysfunctional emotional and physical distress that interferes with the individual's quality of life and functioning. A novel understanding of the bimodal opioid modulation of pain, and its impact, through serotonergic, dopaminergic, epinephrinergic, and norepinephrinergic processes, on hedonic tone, leads directly to new generation pharmaceutical formulations that are remarkably safe and effective for the treatment of a wide variety of Distress Dysfunctions, including anxiety, depression, anger, insomnia, mood disorders, eating disorders, sexual problems, pain, substance and behavioral addictions, gastrointestinal disorders, autistic spectrum disorders, attention-deficit and hyperactivity disorders, and other emotional and physical distress disorders. The foundation of this discovery is the power of Receptor Switchers, such as ultra-low-dose and very-low-dose opioid antagonists and GM1 ganglioside attenuators, in blocking acute and protracted excitatory opioid receptor signaling. Co-administration of Receptor Switchers with Endorphin Enhancers, such as specific cAMP PDE inhibitors and excitatory amino acids, is an excellent formulation for restoring healthy homeostatic balance to the endogenous opioid system, using the body's endorphins to reduce emotional and physical distress, and through synergistic and homeostatic processes, restoring positive hedonic tone. The addition of Synergistic Enhancers, such as amino acids, SSRI and SNRI agents, and non-opioid analgesics, as well as Exogenous Opioids, enhances and prolongs these therapeutic benefits. The novel principles discovered by this invention also teach a new generation of safe and effective formulations for the treatment of respiratory conditions, neuropathy, and nociceptive pain.

The invention combines two different subunits with different release profiles in novel sustained-release oral dosage forms. In particular, the oral dosage forms include a subunit that comprises an opioid analgesic and a sustained-release material, wherein the dissolution rate in-vitro of the subunit, when measured by the standard USP Drug Release test of U.S. Pharmacopeia XXVI (2003) <724>, is less than about 10% within about 6 hours and at least about 60% within about 24 hours; less than about 10% within about 8 hours and at least about 60% within about 24 hours; or less than about 10% within about 12 hours and at least about 60% within about 24 hours; the dosage form providing a duration of therapeutic effect of about 24 hours.

A sustained release formulation by using dimeticone as the dispersion medium, which includes active ingredient (e.g., drugs against parasites, insecticides, NSAIDs, antibiotics, sex hormone like agents or oily soluble vitamins) and dimeticone as the medium. Suitable stabilizer, antioxidant, local analgesics and material for sustained release may be added. The formulation is bio-compatible, stable and injectable.

A transdermal analgesic system having reduced potential for abuse, wherein the system provides for the controlled release of the antagonist at a rate sufficient to provide an abuse limiting release rate ratio of the antagonist to the analgesic when the dosage form is subject to abuse is disclosed.
