In this study, we examined the interaction between histamine H1 receptor and μ-opioid receptor in scratching behavior in ICR mice. Both histamine and morphine caused scratching and simultaneous injection of histamine and morphine had an additive effect. Chlorpheniramine and naloxone inhibited histamine-induced scratching behavior. These two drugs also inhibited morphine-induced scratching behavior. Simultaneous injection of chlorpheniramine and naloxone caused a significant inhibition of histamine-induced scratching compared with separate injections. The same findings were also noted for morphine-induced scratching. These results strongly indicate a close relationship between histamine H1 receptor and μ-opioid receptor in scratching behavior in ICR mice.
