An abuse-deterrent pharmaceutical composition has been developed to reduce the likelihood of improper administration of drugs, especially drugs such as opiods. In the preferred embodiment, a drug is modified to increase its lipophilicity. In preferred embodiments the modified drug is homogeneously dispersed within microparticles composed of a material that is either slowly soluble or not soluble in water. In some embodiments the drug containing microparticles or drug particles are coated with one or more coating layers, where at least one coating is water insoluble and preferably organic solvent insoluble, but enzymatically degradable by enzymes present in the human gastrointestinal tract. The abuse-deterrent composition retards the release of drug, even if the physical integrity of the formulation is compromised (for example, by chopping with a blade or crushing) and the resulting material is placed in water, snorted, or swallowed. However, when administered as directed, the drug is slowly released from the composition as the composition is broken down or dissolved gradually within the GI tract by a combination of enzymatic degradation, surfactant action of bile acids, and mechanical erosion.

Pharmaceutical compositions are provided containing a combination of benzonatate and guaifenesin, or pharmaceutically acceptable salts thereof.

A method for detecting the need for providing assistance to an individual suspected of overdosing on an opiate is provided. The method includes using a wearable device for continuous or intermittent monitoring of one or more physiological parameters of the individual. If the level of one of the one or more physiological parameters exceeds a threshold level specific to that parameter, an alarm is triggered. If the alarm is not aborted, an alert is transmitted to one or more emergency contacts conveying that the individual has overdosed. The method optionally provides for injection of an opioid receptor antagonist into the individual to reverse the effects of the overdose. Also provided is a device for implementing these methods.

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 present invention pertains to a non-invasive method and apparatus for predicting or monitoring analgesia and blood levels of opioid drugs in a patient receiving pain treatment, e.g., during palliative treatment. The inventive method comprises the measurement of one or more, preferably two or more, surrogate markers of a patient. According to the present invention surrogate markers correlate with the level of analgesia in the opioid receiving subject and thus provide a non-invasive method to predict and monitor analgesia during a treatment.
