Abstract:
Objective To develop an oxybutynin nanotransdermal formulation with high skin permeability based on cubsomes carrier.Methods The oxybutynin loaded cubsomes(OXY-CS)was prepared by ultrasonic method.Using particle size,polydispersity index and encapsulation efficiency as evaluation indexes,stirring temperature,stirring time,stirring speed,ultrasound time,ultrasound power,glycerol monooleate/poloxamer 407 ratio(GMO/F127),carrier(GMO+F127)/drug ratio and drug concentration were optimized.The effects of drug concentration,permeation promoter and gel matrix type on skin permeability were investigated using cumulative permeation and skin retention as evaluation indicators.Results The prepared OXY-CS had small particle size and high encapsulation efficiency at stirring temperature of 50℃,stirring time of 30 min,stirring speed of 1 000 r/min,ultrasound time of 10 min,ultrasound power of 100 W,GMO/F127 ratio of 2∶1,carrier/drug ratio of 3∶1 and drug concentration of 1％,respectively.OXY-CS had high cumulative penetration and skin retention at concentration ≥ 3％.The addition of a permeation promoter to OXY-CS did not increase the cumulative penetration of the drug.The skin permeability of oxybutynin cubsomes gel made with carbomer was significantly better than those of other gel matrices.Conclusion In this study,oxybutynin is made into a topical cubsomes gel,which is expected to reduce the incidence of adverse effects associated with oral administration.
