Used as a selective inhibitor of calcium channels, particularly targeting T-type calcium channels, making it valuable in research related to neuronal excitability and pain signaling. Commonly applied in studies exploring epilepsy, neuropathic pain, and cardiovascular function due to its ability to modulate ion channel activity without affecting other major channel types. Frequently utilized in in vitro and in vivo models to dissect the role of specific calcium channel subtypes in cellular physiology.
