Reversal of clonidine induced miosis by the alpha 2-adrenoreceptor antagonist RX 781094.

Clonidine given i.v. at a dose of 0.1 mg and 0.2 mg was found to cause miosis in a placebo controlled double-blind study in six healthy volunteers. In a further single-blind placebo controlled study in three of these volunteers, the alpha 2-adrenoreceptor antagonist RX 781094 at a dose of 0.1 mg/kg i.v. reversed the miosis induced by i.v. clonidine 0.2 mg. At a dose of 0.05 mg/kg the miosis was partially reversed.
