Abstract

The invention is directed to an immediate release capsule which mitigates the abuse of Tapentadol or physiologically acceptable salt thereof by direct intravenous injection. The capsule comprises a tamper resistant formulation which when mixed with water and heated, results in a turbid, bubbling mixture that is not injectable with a standard insulin syringe.
