Adrenergic drugs stimulate adrenergic receptors, thereby activating the sympathetic nervous system and inducing symptoms characteristic of the fight-or-flight response (sympathetic stimulation)..

Classify & describe adrenergic β-agonists including actions, therapeutic uses & adverse. .. Adrenomimetics. - it is drugs that imitate the action of . noradrenaline. (NA) in the adrenergic synapses and cause the sympathetic effects on internal organs.. Thus, the main "target" action agonists is adrenergic synapse, which has certain structural and functional features..
