Summary for Patent: 9,044,398
Title:Abuse-deterrent pharmaceutical compositions of opiods and other drugs
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, 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.

For Orange Book-listed patents (shown in the main table above) generic applications must certify that the listed patents are expired, invalid, or will not be infringed by generic entry.

The non-Orange Book patents listed below do not require formal certifications, so they do not automatically impede generic entry. Instead, they represent potential opportunities for branded firms to block generic entry through patent infringment challenges.
