Abstract
The present invention provides provide a dosage form that prevents misuse of the medicament contained within. The dosage form contains an inactivating substance in combination with the medicament, wherein the two substances are separated by a permeable or semi-permeable partition. The partition becomes impermeable upon activation by a medical professional, thereby effectively sequestering the inactivating substance from the medicament and allowing for the intended administration of the medicament to the patient. Unless activated, however, the inactivating substance and medicament remain commingled in the dosage form, and any attempt to dispense the medicament before activation will result in the release of inactivated medicament.
