Publication number: 20130337061Abstract: Pharmaceutical compositions are provided for the pharmacological treatment of breathing disorders and, more specifically, to compositions containing agents having serotonin receptor modulating activity for the alleviation of sleep apnea (central and obstructive) and other sleep-related breathing disorders wherein the active ingredients are released such as to extend effective blood plasma concentrations across the period of sleep.Type: ApplicationFiled: August 19, 2013Publication date: December 19, 2013Applicant: Collegium Pharmaceutical, Inc.Inventors: Roman V.

Patent number: 8557291Abstract: 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.Type: GrantFiled: May 27, 2009Date of Patent: October 15, 2013Assignee: Collegium Pharmaceutical, Inc.Inventors: Roman V. Rariy, Alison B. Fleming, Jane Hirsh, Alexander M. Klibanov

Publication number: 20130045960Abstract: 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. 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.Type: ApplicationFiled: July 17, 2012Publication date: February 21, 2013Applicant: Collegium Pharmaceuticals, Inc.Inventors: Jane Hirsh, Alexander M. Klibanov, Timothy M. Swager, Stephen L. Buchwald, Whe Yong Lo, Alison Fleming, Roman V. Rariy

Publication number: 20100260834Abstract: 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.Type: ApplicationFiled: June 25, 2010Publication date: October 14, 2010Inventors: Jane C.

Publication number: 20080044462Abstract: Pharmaceutical compositions for transdermal administration containing a fatty acid salt, a dicarboxylic acid salt, an alkyl sulfonic acid salt, an aryl sulfonic acid salt, or an alkyl aryl sulfonic acid salt of an unstable active agent, such as bupropion free base or a derivative of burpropion free base, such as bupropion free base or derivative of bupropion free base, paroxetine, fluvoxamine, fluoxetine, sertraline, venlafaxine, duloxetine, and metabolites and derivatives thereof are described herein. The composition may also contain one or more antioxidants. The compositions can be prepared by forming the bupropion salt followed by addition of the antioxidant. Alternatively, bupropion can be combined first with the antioxidant followed by addition of the acid to form the salt. The compositions can be administered as a gel, cream, lotion, ointment, or patch and typically contain a pharmaceutically acceptable carrier and optionally one or more pharmaceutically acceptable excipients.Type: ApplicationFiled: April 6, 2007Publication date: February 21, 2008Inventors: Mark W.
