Emulsions are applied orally, topically, and parenterally in pharmaceutical merchandise. Steadiness is obtained as a result of emulsifying agents which reduce interfacial tension amongst phases. The kind of emulsion is dependent upon the solubility on the emulsifying agent made use of.
This doc delivers an summary with the evaluation of read more semisolid dosage kinds for example ointments, creams, and suppositories. It discusses great Qualities of semisolids and categories of semisolids.
