pubmed:abstractText |
Twenty-nine healthy volunteers participated in an experiment lasting for 8 weeks: Phase I (2 weeks)--pre-treatment control period; Phase II (4 weeks)--medication with either ciclazindol hydrochloride (50 mg twice daily), or desipramine hydrochloride (50 mg twice daily) or lactose placebo (twice daily) administered in a single-blind fashion; Phase II (2 weeks)--recovery. Experimental sessions took place twice weekly for the photographic assessment of resting pupil diameter, and for the assessment of one of the following pupillary responses: mydriatic response to methoxamine, mydriatic response to tyramine, miotic response to pilocarpine. Resting pupil diameter increased during medication with either ciclazindol or desipramine. Methoxamine-evoked mydriasis and tyramine-evoked mydriasis were antagonized by both ciclazindol and desipramine. Pilocarpine-evoked miosis was potentiated by both ciclazindol and desipramine. The steady-state plasma levels (mean +/- s.e. mean) of the antidepressants were: ciclazindol: 5.90 +/- 0.74 microM; desipramine: 0.60 +/- 0.17 microM. The antagonism of methoxamine-evoked mydriasis is likely to reflect the blockade of postsynaptic alpha 1-adrenoceptors in the iris by the antidepressants, whereas the antagonism of tyramine-evoked mydriasis may reflect both the blockade of uptake of tyramine into presynaptic adrenergic terminals and the blockade of postsynaptic alpha-adrenoceptors. There is no immediate explanation for the potentiation of pilocarpine-evoked miosis by the two antidepressants.
