  • Publication number: 20130310413
    Abstract: An abuse-deterrent pharmaceutical composition has been developed to reduce the likelihood of improper administration of drugs, especially drugs such as opioids. In one embodiment, the drug is modified to increase its lipophilicity by forming a salt between the drug and one or more fatty acids wherein the concentration of the one or more fatty acids is one to 15 times the molar amount of the active agent. The abuse-deterrent composition prevents the immediate release of a substantial portion of drug, even if the physical integrity of the formulation is compromised 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.

  • Patent number: 8557291
    Abstract: An abuse-deterrent pharmaceutical composition has been developed to reduce the likelihood of improper administration of drugs, especially drugs such as opioids. In a preferred embodiment, a drug is modified to increase its lipophilicity. In some embodiments the modified drug is homogeneously dispersed within spherical 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/or organic solvent insoluble. 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 passes through the GI tract.

  • Patent number: 8449909
    Abstract: 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, the drug is modified to increase its lipophilicity by forming a salt between the drug and one or more fatty acids wherein the concentration of the one or more fatty acids is one to 15 times the molar amount of the active agent, preferably two to ten times the molar amount of the active agent. In one embodiment 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.

  • Patent number: 7038085
    Abstract: The present invention relates generally to the enantiomers of para-hydroxy-milnacipran or congeners thereof. Biological assays revealed that racemic para-hydroxy-milnacipran is approximately equipotent in inhibiting serotonin and norepinephrine uptake (IC50=28.6 nM for norepinephrine, IC50=21.7 nM for serotonin). Interestingly, (+)-para-hydroxy-milnacipran is a more potent inhibitor of norepinephrine uptake than serotonin uptake (IC50=10.3 nM for norepinephrine, IC50=22 nM for serotonin). In contrast, (?)-para-hydroxy-milnacipran is a more potent inhibitor of serotonin uptake compared to norepinephrin uptake (IC50=88.5 nM for norepinephrine, IC50=40.3 nM for serotonin). The invention also relates to salts and prodrug forms of the aforementioned compounds. In certain embodiments, the compounds of the present invention and a pharmaceutically acceptable excipient are combined to prepare a formulation for administration to a patient.
