The use of dihydropyridines (DHPs) as a tool for calcium channel blockade led to the identification of a subtype as “long-lasting” or L-type as they show slow voltage-dependent .
As mentioned previously, calcium can be passively released from the ER into the cytosol through ER-resident IP3Rs and RyRs termed calcium-induced calcium release (CICR) channels [23,43]. Seizures disrupt ion concentrations in the brain, including potassium and calcium, leading to the depolarization of neighboring neurons and the increased release of neuromodulators like zinc, which contribute to abnormal brain activity.
Three major classes of mechanism are recognised: modulation of voltage-gated ion channels; enhancement of gamma-aminobutyric acid (GABA)-mediated inhibitory neurotransmission; and attenuation of glutamate-mediated excitatory neurotransmission.

Drugs that affect calcium currents – There are three types of calcium channels in neurons, each of which is distinguished by its rate of reactivation and voltage dependency. Low-threshold T-type calcium currents inactivate quickly and have been described in experimental preparations of thalamic relay neurons. Here, we investigate the contribution of L-type voltage-gated calcium channels (VGCC) to epileptiform activity induced in cultured hippocampal neurons by GABA (A)R antagonist, bicuculline. Using KCl-induced depolarization, we determined the optimal effective doses of the blockers.
Calcium channel blockers are anti-epileptic drugs that change how abnormal electrical activity affects the brain. This helps stop or reduce epilepsy seizures.
