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.
