Abstract
Clenbuterol, isoproterenol and salbutamol increased the latency in the licking response of mice on the hot plate at 56.5° C. This effect was dose-related and obtained after IP administration. Clenbuterol was active at lower doses than isoproterenol and salbutamol, a result which is consistent with its better penetration in the central nervous system. Moreover, the effect of clenbuterol was stereospecific, the (−)-isomer being the active form. Our results suggest the implication of central beta-adrenoceptors in the modulation of the response to a painful stimulation.
