    Abstract:
    The effects of various inhibitors of 5-HT uptake on plasma glucose have been studied in normal and monoamine oxidase inhibitor pretreated mice. Additionally their interaction with 5-hydroxytryptophan (5-HTP) in producing hypoglycaemia was studied. Clomipramine, fenfluramine, fluoxetine, ORG 6582 (dl-8-chloro-11-anti-amino-benzo-(b)-bicyclo[3.3.1]nona-3, 6 alpha(10 alpha)-diene hydrochloride), ORG 6997 (dl-4-exo-amino-8-chloro-benzo-(b)-bicyclo[3.3.1]nona-2-6 alpha(10 alpha)-diene hydrochloride), MK 212 and mazindol did not modify the plasma glucose in normal mice but produced hypoglycaemia in mice pretreated with either nialamide or pargyline. Dexamphetamine did not influence plasma glucose in either normal or monoamine oxidase inhibitor pretreated mice. Each of the above drugs except ORG 6997 but including dexamphetamine augmented the hypoglycaemic effect of 5-HTP in normal mice. These responses did not appear to be mediated by insulin since none of the drugs increased the plasma immunoreactive insulin concentration or augmented the hyperinsulinaemic effect of 5-HTP. Moreover, fenfluramine, fluoxetine and ORG 6582 did not augment the hypoglycaemic action of injected insulin although such an augmentation was produced by mazindol.
