摘要：
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 the particles to be incorporated into abuse-deterrent medicaments.
