Application

Mibefradil has been used as a T-type calcium channel blocker in various cells. It has also been used to reduce apoptosis of retinal ganglion cells (RGC) in EphB2-Fc.

Biochem/physiol Actions

Mibefradil is a tetralol derivative and nondihydropyridine calcium channel blocker. It blocks long-type (L-type) calcium channels. It blocks mildly the Purkinje-type (P-type) calcium channels in Purkinje neurons.
Ro 40-5967 is a T-type Ca2+ channel blocker; antihypertensive.
