Ointment dosage forms incorporation

There are two primary methods of manufacturing ointment dosage forms incorporation and fusion. Each may be used on a small scale (laboratory) or large scale (industry) for the manufacture of semisolid dosage forms. 

Topical formulations. Drug nanoparticles can be incorporated into creams and water-free ointments. The nanociystalline form leads to an increased saturation solubility of the drug in the topical dosage forms, thus enhancing the diffusion pressure into the skin.
