Publication number: 20180028528Abstract: 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.Type: ApplicationFiled: October 5, 2017Publication date: February 1, 2018Inventors: Jane Hirsh, Alexander M. Klibanov, Timothy M. Swager, Stephen L. Buchwald, Whe Yong Lo, Alison B. Fleming, Roman V. Rariy

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: GrantFiled: July 17, 2012Date of Patent: June 2, 2015Assignee: Collegium Pharmaceutical, Inc.Inventors: Jane Hirsh, Alexander M.

Patent number: 7585520Abstract: Compositions containing both a sedative compound and a non-sedative antihistamine are provided. More particularly, compositions for administration at bedtime containing a sedating antihistamine or other sedating compound in immediate release form and a non-sedating antihistamine in delayed-release form are described. Alternatively, a composition, for administrating upon awakening, containing a non-sedating antihistamine in immediate release form, and a sedating antihistamine or other sedative in delayed-release form is described. Methods of inhibiting the release of histamines by administration of the compositions to a mammalian subject are also provided. The dosage forms may comprise other medications, such as leukotriene receptor antagonists, to enhance the suppression of histamine symptoms.Type: GrantFiled: September 17, 2004Date of Patent: September 8, 2009Assignee: Collegium Pharmaceutical, Inc.Inventors: Mark Hirsh, Jane Hirsh, Whe-Yong Lo

Publication number: 20080317830Abstract: Compositions for the treatment of wounds and/or scars are described herein. The compositions contain between 1 and up to 30% by weight, more preferably between 1 and 20%, most preferably between about 5 and 10% by weight particles, such as titanium dioxide or a similar material in a pharmaceutically acceptable base or carrier, such as petrolatum. The compositions are less greasy than petrolatum alone, and thus are more aesthetically pleasing. The compositions exhibit occlusive properties comparable to petrolatum. The compositions are absorbed into the skin, unlike petrolatum, and exhibit significant wound healing characteristics not observed with petrolatum alone. In one embodiment, the pharmaceutically acceptable base is petrolatum and the particles are titanium dioxide. The compositions can be used to treat complex, hard to heal wounds, such as diabetic ulcers; pressure sores, such as bed sores; lacerations; bite wounds; burns; penetrating wounds; surgical wounds, etc.Type: ApplicationFiled: June 25, 2007Publication date: December 25, 2008Applicant: LioLabs LLCInventors: Jay A.
