Abstract: Porous particles comprising an active ingredient and a coating exhibiting greater dissolution rate in aqueous media than in alcoholic media are disclosed. A process for the manufacture of the particles is also disclosed, as well as tamper-proof particles and solid dosage forms comprising the coated particles. The differential solubility characteristics of the particle coating allow low the particles to be incorporated into abuse-deterrent medicaments.

Abstract: Processes for preparing porous particles are disclosed, in which the resulting particles release an encapsulated active ingredient more readily in aqueous media than they do in alcoholic media. Also described are the particles themselves, as well as tamperproof, abuse-deterrent, dosage forms comprising the porous particles. The release characteristics of the porous particles make them useful for overcoming drug-abuse techniques, such as dose-dumping in alcoholic media.
