Central noradrenaline depletion attenuates amphetamine-induced locomotor behavior
Abstract:
Male rats were given 6-hydroxydopamine-induced lesions of the locus coeruleus (LC) or the dorsal noradrenergic bundle (DNAB), prior to the measurement of locomotor and rearing activity induced by D-amphetamine. The increased locomotor activity induced by D-amphetamine (1.8 mg/kg) was significantly attenuated by both the LC and the DNAB lesions. The stimulatory effect of the 7.2 mg/kg dose of amphetamine was attenuated by the LC lesion, whereas the DNAB lesion potentiated this effect. The LC lesion also attenuated rearing induced by the 7.2 mg/kg dose of amphetamine. These results suggest some involvement of central noradrenergic neurons in the activity induced by amphetamine in the rat.

Adrenergic Agonists: Indirect-Acting Agents
One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral bioavailability, and...
Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
