摘要: 本试验旨在考察重组人干扰素α1b喷雾剂在皮肤应用的局部药代动力学特性,分别在小型猪完整皮肤、通透性增强皮肤和破损皮肤上进行透皮吸收研究。采用1、3、5及25 μg/mL重组人干扰素α1b喷涂于受试部位,在用药后0、1、2、4 h分别取用药部位皮肤组织制成匀浆,检测匀浆中干扰素活性。药物可渗透进入小型猪完整皮肤;在小型猪通透性增强和破损皮肤中,用药4 h内,药物可达到有效治疗浓度;用药剂量和用药时间与皮肤组织中药物活性相关,不同剂量组间和不同检测时间组间差异显著(P<0.05)。5 μg/mL重组人干扰素α1b喷雾剂间隔4 h用药可在用药局部起到抗病毒作用。

Abstract: To study the skin pharmacokinetics of interferon α1b spray, the pharmacokinetics of interferon α1b spray on the skin was carried out in the integral, permeable and injured skin of the minipigs. 1, 3, 5, 25 μg/mL of recombinant human interferon α1b were consperged onto animal’s skin. Skin tissues were shearing and homogenated at 0,1,2,4 h after consperge. The biological activity of interferon α1b was measured to show the drug’s antiviral effect. The interferon α1b was detected in integral skin and achieved to therapeutic concentration in permeable and injured skin of minipigs within 4 h after consperging; the concentrations of interferon α1b in tissues were correlated with dosage and time, those differences between groups were significant (P<0.05). 5 μg/mL interferon α1b spray showed antiviral effect on skin region when sprayed every 4 h.
