Abstract:
1. The role of ATP sensitive potassium channels in the analgesic activity of prolactin (PRL) was studied in mice using glibenclamide and minoxidil, a blocker and an opener of these channel, respectively. 2. Pre-treatment with glibenclamide attenuated the analgesic activity of PRL while treatment with minoxidil potentiated the activity. 3. It is concluded that PRL, similar to morphine, utilizes ATP sensitive potassium channels in eliciting the analgesic response.
