Objective To research the drug effects on laboratory animals' central nervous system, respiratory system, cardiovascular system and digestive system of recombinant human interferon β-1a injection under the certain dosages thereby observing the potential adverse effects on physiological functions and providing basis and reference for clinical experiment.Methods The mice received a single dose of 5.5, 22.0, and 88.0 μg/kg of recombinant human interferon β-1a injection by sc injection and the effects on central nervous system were studied by observing the autonomic activity of mice, carrying out balance and coordination ability test and coordinating sleep experiments. The cynomolgus monkeys received a single dose of 1, 4 and 16 μg/kg of recombinant human interferon β-1a injection by sc injection and the effects on respiratory system and cardiovascular system were observed. The mice received a single dose of 5.5, 22.0, and 88.0 μg/kg of recombinant human interferon β-1a injection by sc injection and the effects on digestive system were observed through gastrointestinal propulsion experiment.Results No significant changes in spontaneous activities of mice after a single dose of 5.5, 22.0 and 88.0 μg/kg of recombinant human interferon β-1a injection administration were found. The balance and exercise abilities of mice showed no impacts. No function together with subthreshold dose of sodium pentobarbital to cause mice sleep were found. No significant changes in respiratory and cardiovascular system of cynomolgus monkeys after a single dose of 1, 4 and 16 μg/kg of recombinant human interferon β-1a injection by hypodermic injection were found. No significant changes in gastrointestinal propulsive effect of mice after a single dose of 5.5、22、88 μg/kg of recombinant human interferon β-1a injection by hypodermic injection were found.Conclusions Recombinant human interferon β-1a injection showed no significant influences on laboratory animals' central nervous system, respiratory system, cardiovascular system and digestive system.
