摘要:
A topical liquid aerosol formulation for accurate metered dose delivery has been developed which includes a concentrate comprising a local anesthetic in a non-alcohol solvent and a hydrofluorocarbon (HFC) propellant. In the preferred embodiment, the concentration of the non-alcohol solvent in the concentrate is between about 75% and 85% by weight of the formulation. In the most preferred embodiment, the non-alcohol solvent is a water-soluble polyol such as ethylene glycol, propylene glycol, glycerol, diethylene glycol, dipropylene glycol, oligoalkylene glycols, liquid polyalkylene glycols, or combinations thereof. In one embodiment, the concentration of the local anesthetic in the concentrate is between about 15% and 25% by weight. In the preferred embodiment, the hydrofluorocarbon propellant is 1,1,1,2-tetrafluoroethane 1,1,1,2,3,3,3-heptafluoropropane or combinations thereof, in a concentration between about 35% and 65% by weight of the final formulation, more preferably between about 45% and 55% by weight of the final formulation. A particularly preferred formulation includes benzocaine, tetracaine, and butylaminobenzoate, wherein the concentration of benzocaine in the concentrate is 14% by weight, the concentration of tetracaine in the concentrate is 2% by weight, and the concentration of butylaminobenzoate in the concentrate is 2% by weight. It has been found that the formulation is more stable in the substantial absence of oxygen. The formulation is preferably administered using a metered dose device for release of a controlled amount of the local anesthetic.

摘要:
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.

Tamper-resistant pharmaceutical compositions have been developed to reduce the likelihood of improper administration of drugs, especially drugs such as opioids. The tamper-resistant compositions retard 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.

摘要:
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. The abuse-deterrent composition prevents the immediate release of a substantial portion 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.
摘要:
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. Finally, the present invention relates to methods of treating mammals suffering from various afflictions, e.g., depression, chronic pain, or fibromyalgia, comprising administering to a mammal in need thereof a therapeutically effective amount of a compound of the present invention.
摘要:
Formulations are described for the treatment by enzymatic debridement of wounds and ulcers. The formulations have a clear, transparent composition that allows for easy visualization of the wound, and are non-staining for easy clean up. These formulations can also exhibit increased enzymatic debridement activity, improved post-treatment lubricity and coating occlusivity, and stability. The formulations, optionally containing non-animal source biologics, may be in the form of lotions, aerosols to provide a spray, or a foam. A non-reactive substrate may be used as a composition carrier. A non-aqueous lotion formulation having improved enzymatic activity is provided. The non-aqueous lotion viscosity is adjusted to achieve high enzymatic activity while maintaining the application benefits of high viscosity non-aqueous lotions. The lotion formulation may be delivered in a patch.
