Abstract
The effects of oxymetazoline and noradrenaline (in the presence of desipramine) on the release of 3H-noradrenaline from rat brain cortex synaptosomes were studied using a superfusion technique. Both drugs (at 1 micrometer concentrations) were found to reduce the depolarization-induced (15 mM K+) release of 3H-noradrenaline. The release-modulating effect of noradrenaline was antagonized by phentolamine and yohimbine. The data provide direct evidence for the hypothesis that alpha-receptors modulating the release of noradrenaline are localized on varicosities of central noradrenergic neurones.Entities:
