Abstract IPA COPYRIGHT: ASHP The effects of N-methylpyrrolidone (N-methyl-2-pyrrolidone; MP) on the permeation of zidovudine (azidothymidine; AZT) in isopropyl myristate through rat skin were studied in vitro. AZT permeation was significantly enhanced by MP. When 50 mul of solution containing 12 mg/ml zidovudine and 20% MP was applied, the plasma level of AZT was about one muM one-2 h after application, although the concentration decreased rapidly and was undetectable at 6 h. Although 34% of the applied dose remained in solution on rat skin at 10 h, MP was not detected. When ethylene-vinyl acetate copolymer (EVA) membrane was used for the controlled release of MP, a considerable plasma AZT level was maintained for 10 h. It was concluded that MP significantly enhances the permeation of AZT through rat skin, with sustained plasma levels achieved with the addition of EVA membrane.
