Patent number: 10668060Abstract: 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.Type: GrantFiled: May 15, 2019Date of Patent: June 2, 2020Assignee: Collegium Pharmaceutical, Inc.Inventors: Roman V. Rariy, Alison Fleming, Jane C. Hirsh, Said Saim, Ravi K. Varanasi

Publication number: 20200093820Abstract: 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: ApplicationFiled: November 27, 2019Publication date: March 26, 2020Applicant: Collegium Pharmaceutical, Inc.Inventors: Roman V.

Patent number: 8758813Abstract: 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.Type: GrantFiled: April 25, 2013Date of Patent: June 24, 2014Assignee: Collegium Pharmaceutical, Inc.Inventors: Jane Hirsh, Alison Fleming, Roman Rariy, Alexander M.
