We have compared, in 60 adult patients, the cardiovascular effects of glycopyrronium 5 µg kg1 and 10 µg kg1 given either simultaneously or 1 min before edrophonium 1 µg kg1. Significant differences between the four groups were detected (P < 0.001). Both groups receiving 10 µg kg1 showed increases in heart rate of up to 30 beat min-1 (95% confidence limits 2832 beat min-1). Use of glycopyrronium 5 µg kg1 provided greater cardiovascular stability and, given 1 min before the edrophonium, was sufficient to minimize early, edrophonium-induced bradycardias. This low dose of glycoprronium provided good control of oropharyngeal secretions.
