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. 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.
已经开发了一种滥用抑制药物组合物,旨在降低药物的不当使用的可能性,特别是像阿片类药物这样的药物。在优选实施例中,药物被改性以增加其亲脂性。在优选实施例中,改性药物均匀分散在由缓慢溶解或不溶于水的材料组成的微粒中。在某些实施例中,含药微粒或药物颗粒被涂覆上一层或多层涂层,其中至少一层涂层是不溶于水且最好是有机溶剂不溶性的,但可被人类胃肠道中存在的酶降解。即使该组合物的物理完整性被破坏(例如通过切割或压碎), resulting material仍然被放入水中、吸入或吞咽,该滥用抑制组合物也会延缓药物的释放。然而,当按照指示使用时,药物会缓慢地从组合物中释放出来,因为组合物会逐渐被酶降解、胆汁酸的表面活性作用和机械侵蚀逐渐破坏或溶解在胃肠道内。
