Effect of Drug modification on properties of Ketoprofen Transdermal Gel

The aim of this study was to develop Ketoprofen (KPF) gel for tansdermal delivery that could enhance dissolution and permeability of KPFand to study the change in release and permeation of transdermal gel after formulating KPF as niosomes and solid dispersions. KPF gels were prepared using Carboxy methyl cellulose (CMC), hydroxyl propyl methyl cellulose (HPMC) and methyl cellulose (MC) with and without permeation enhancers (Tween 80 and Oleic acid). The effect of the polymers and permeation enhancers on the in vitro release and permeation was tested. The best formula was formulated as niosomal and solid dispersion gels. The effect of drug modification on the properties of KPF gel was examined. The results showed that both polymers and permeation enhancers affect release and permeation of KPF transdermal gel. The release and permeation from the niosomal gel were highly prolonged when compared to conventional gel .On the other hand, they were enhanced from the solid dispersion gel.
