Abstract
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.

30. A method of administering an abuse-deterrent pharmaceutical composition comprising orally administering to a patient in need thereof an abuse-deterrent oral dosage form comprising a plurality of microparticles, where each microparticle comprises:
-
a fatty acid salt of one or more drugs prone to abuse; and one or more carrier material(s) comprising fats, fatty substances, waxes, wax-like substances or mixtures thereof wherein the oral dosage form retards the release of the one or more drugs prone to abuse, even if the physical integrity of the dosage form is compromised and the compromised dosage form is placed in water. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)
