Formulation and Development of Non-Aqueous Emulsion

The delivery of poorly water-soluble drugs has been the subject of much research, as approximately40% of new chemical entities are hydrophobic in nature. One area in which published literature islacking is the field of non-aqueous emulsions and some researchers have used polyethylene glycol(PEG) as a continuous phase for such emulsions (1-6). The nature of this emulsion will allow capsulefilling at a later stage. In the present study, an attempt has been made to develop non-aqueous emulsionsof the type oil-in-PEG suitable for drug loading.
