Abstract:
The aim of this study was to investigate the effects of the 5-HT1A receptor agonists buspirone and ipsapirone (1-10 mg/kg) on plasma adrenaline (A) levels and on glycemia in the conscious rat. The results indicate that buspirone was able, within 5 min, to increase plasma A and glucose levels in a dose-dependent manner. Ipsapirone administration triggered similar patterns, except that the highest dose used (10 mg/kg) promoted a time-dependent increase in plasma A and glucose levels that was maximal at the end of analysis.

Adrenergic Receptors: β Subtype
Isoprenaline > Adrenaline > Noradrenaline
Neurotransmitter binding to these receptors causes activation of adenylyl cyclase resulting in increased concentrations of cAMP and modulation of calcium ion channels within the cell. They are further classified into β1, β2, and β3 subtypes.

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.
