Abuse resistant drug formulation
A pharmaceutical composition may include a coated particulate which may include at least one active pharmaceutical ingredient, particularly one susceptible to abuse by an individual. The coated particles may include a fat/wax and have improved controlled release and/or crush resistance. Method of making these coated particulate and dosage forms therewith are also described.
