pubmed:abstractText |
The effects of clonidine on adrenal catecholamine (adrenaline and noradrenaline) secretion were investigated in chloralose-anaesthetized dogs. Intravenous administration of clonidine (10 and 20 micrograms kg-1) induced a decrease in both adrenal catecholamine secretion rates and cardiovascular parameters (blood pressure and heart rate). In contrast, a dose of 5 micrograms kg-1 was ineffective. Intracisternal clonidine (in a lower dose of 3 micrograms kg-1) also decreased adrenaline and noradrenaline release from the adrenal gland. Clonidine failed to modify adrenal catecholamine release evoked by electrical stimulation of the splanchnic nerve. These results demonstrate that clonidine decreases adrenaline release from the adrenal gland through a central and not a peripheral mechanism in dogs. This action might contribute to its antihypertensive effects.
