英文摘要 | Two microemulsion systems were developed for percutaneous delivery of PGE1 and its alkyl esters through hairless mouse skin. Microemulsion I was based on Labrasol (HLB 14) as a nonionic surfactant and Plurol oleique (HLB 10) as a cosurfactant, whereas microemulsion Ⅱ employed Labrafac CM 10 (HLB 10) as a nonionic surfactant and Lauroglycol (HLB 4) as a cosurfactant. The addition of a variety of cosolvents into both microemulsion systems was found to cause insignificant effects on the formation of the microemulsions. The effect of a variety of cosolvents on the percutaneous penetration of PGE�� and its alkyl esters through hairless mouse skin was further examined. The penetration of all the prostaglandins examined from microemulsion Ⅱ was insignificant compared to microemulsion Ⅰ. The penetration rate of PGE�硬as higher than its alkyl esters from microemulsion Ⅰ with the same cosolvent. The enhancement of PGE1 percutaneous penetration from microemulsion Ⅰ was positively correlated with the hydroxyl number of polyhydric alcohols. For a given number of hydroxyl groups, an alcohol with an optimal carbon number enhanced the penetration rate to the greatest degree. However, the penetration rate of PGE�� from all formulations appeared inadequate for practical use. |
