Effect of catecholaminergic drugs on epileptogenic properties of the caudate nucleus
Abstract:
Drugs stimulating catecholaminergic transmission (dopa, apomorphine, amphetamine, and their combination with disulfiram) weakened the epileptogenic properties of the caudate nucleus in freely moving rats. Under the influence of these drugs the cortical electroencephalographic response to single stimulation of the nucleus was shortened in animals receiving subconbulsant doses of leptazol and the intensity of the spike-wave rhythm bound with repeated caudate stimuli was reduced. Conversely, inhibitors of catecholaminergic transmission (chlorpromazine, haloperidol, alpha-methyltyrosine, and disulfiram) potentiated the epileptogenic effects of the caudate nucleus.

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...

Antiepileptic Drugs: Calcium Channel Blockers
Calcium channel blockers exert their antiepileptic effects by targeting T-type calcium channels, which are integral to transmitting nerve signals in the central nervous system. These channels allow the passage of calcium ions, which are vital for neuronal communication. By inhibiting T-type calcium channels, calcium channel blockers effectively reduce the release of neurotransmitters and...
