Hard shell capsules filled with a pharmaceutical medicament and at least one modifier, selected to prevent abuse of the medicament are described. The modifier may have a high melting point, and therefore melt at a temperature too high to inject or be insoluble in liquid, having a density less than 1, to prevent "spiking" of drinks. The modifier may also be a waxy substance which cannot be crushed, a viscosity modifier, a dye or a taste modifier.
