COMPARISON OF EFFECT OF PENETRATION ENHANCER ON DIFFERENT POLYMERS FOR DRUG DELIVERY
Objective: Aliskiren hemifumarate is used for the treatment of hypertension. The aim of this research to study the effect on the delivery of drug using natural and synthetic permeation enhancers like limonene, cineol, Î²-cyclodextrin, and oleic acid by using different polymers. As different penetration acts differently with polymers.
Methods: Transdermal patches were prepared by the solvent evaporation technique. The controlled release polymers were used for the preparation of patches. The patches were prepared with different polymers and different plasticizer. The drug and polymer interaction study was performed by Fourier transform infrared spectra. In vitro permeation studies were conducted using pretreated cellophane membrane using franz diffusion cell.
Results: The prepared patches were evaluated for in vitro drug release, and the release profile was varied from 52.32% PGH (oleic acid) to 87.63% B (cineol). The permeability coefficient was found in the range of 5.82 to 8.32 cm/h, and corresponding flux was found between 281.61 to 729.08 Âµg/cm2/h on the prepared patches and statistical analysis performed using t-test (p<0.005).
Conclusion: On the basis of the obtained results, it was concluded that patch prepared using methocel k 15 m as a polymer, glycerin as plasticizer and cineol as a permeation enhancer shows the maximum release. The increase in the release due to increase in the flux.
