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.
