Abstract:
Topiramate (TPM) is a new anti-convulsant drug, prescribed in epileptic seizure. Pharmacological actions of TPM are: a) a positive modulation of GABA receptors; b) inhibition of the kainite and aminohydroxymethylisoxazole propionic acid (AMPA) glutamate receptor sub-types; c) a use-dependent Na+ channel blocker. Recent studies suggest that TPM can have anti-excitotoxic properties, because it protects against motor neuron degeneration. Moreover, TPM enhances neuroprotection and reduces hemorrhagic incidence in focal cerebral ischemia.

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...
