The potential antidepressant effect of flerobuterol (dl-(fluoro-2 phenyl)-1 t-butylamino-2 ethanol), a new drug related to beta-adrenoceptor agonists, was evaluated and compared with imipramine and salbutamol using classical psychopharmacological tests in mice. Like imipramine and salbutamol, flerobuterol (0.5-32 mg kg-1, ip) fully prevented apomorphine (16 mg kg-1, sc)- and partly reversed reserpine- and oxotremorine-induced hypothermia. At higher doses (16-32 mg kg-1), flerobuterol enhanced the toxic effects of yohimbine. Unlike imipramine, flerobuterol and salbutamol did not reduce immobility duration in the behavioural despair test. Salbutamol and flerobuterol decreased locomotor activity. Flerobuterol did not induce mydriasis, did not prevent oxotremorine-induced tremors or salivary and lacrimal gland secretion and did not reduce reserpine-induced palpebral ptosis. Propranolol (8 mg kg-1, ip) but not alpha-methyl-paratyrosine (75 mg kg-1, ip) prevented the flerobuterol-induced antagonism of apomorphine-induced hypothermia. Our results suggest that flerobuterol demonstrates potential antidepressant activity, which could be related to beta-adrenoceptor activation in mice.

The pharmacological profile of salbutamol, an agonist of beta-adrenergic receptors and a potential antidepressant drug, and its effect on the central serotonin system were studied. It was found that salbutamol either had no effect, or, at higher doses, inhibited the spontaneous activity of mice and rats; it did not influence significantly either the produced by amphetamine locomotor stimulation (in mice and rats) or amphetamine stereotype (in rats). Salbutamol while not affecting body temperature of normal mice reversed hypothermia but not ptosis induced by reserpine, and counteracted the hypothermic action of apomorphine in mice. It neither affected the spiperone-induced catalepsy nor was active in the behavioural despair test in rats. Salbutamol had no effect either, on the fenfluramine-induced hyperthermia in rabbits, on the 5-hydroxytryptophan-induced head twitch reaction in mice, on the tryptamine-induced clonic convulsions of forepaw in rats on the flexor reflex in spinal rats, or on the quipazine- or fenfluramine-induced stimulation of this reflex. The above findings indicate that the pharmacological profile of salbutamol resembles that of classical imipramine-like antidepressant drugs to a very small extent and it does not affect the central serotonergic transmission.
