The effect of clonidine and bright light on plasma melatonin
We studied the effect of α2-adrenoceptor agonist, clonidine, and bright artificial light (> 2500 lux) on the nocturnal increase in plasma melatonin in normal subjects. Clonidine (1.5 μg/kg, intravenously) was without effect on plasma melatonin concentration. In contrast, bright light treatmen...

Summary: | We studied the effect of α2-adrenoceptor agonist, clonidine, and bright artificial light (> 2500 lux) on the nocturnal increase in plasma melatonin in normal subjects. Clonidine (1.5 μg/kg, intravenously) was without effect on plasma melatonin concentration. In contrast, bright light treatment abolished the increase in night-time melatonin. Bright light is a simple and effective means of altering melatonin secretion in humans. |
