Decitabine

Nonionic surfactant vesicles (niosomes) were formulated with an aim of enhancing the oral bioavailability of Decitabine, an anti-cancer drug. Niosomes were formulated by conventional thin film hydration technique with different molar ratios of surfactant, cholesterol and dicetyl phosphate. The formulated niosomes were found spherical in shape, ranging from 2.95 𝜇m to 10.91 𝜇m in size. Vesicles with 1 : 1 : 0.1 ratios of surfactant : cholesterol : dicetyl phosphate with each grade of span were found to have higher entrapment efficiencies, which were further selected for in vitro studies. Vesicles formulated with sorbitan monostearate were found to have maximum drug release (99.091%) at the end of 24 hours and followed zero order release kinetics. In conclusion, noisome could be a promising delivery for Decitabine with improved oral bioavailability and prolonged release profiles.
