[2] Compared with certain other L-type calcium channel blockers (for example those of the phenylalkylamine class such as verapamil) that have significant action at the heart, the dihydropyridine calcium channel blockers lower blood pressure mainly by relaxing the smooth muscle of the blood vessel ...
Venom of the Agelenopsis spider is a specific P-type calcium channel blocker. The two known blockers which are specific to P-type calcium channels are peptides derived from the spider venom of Agelenopsis aperta. The toxins from this venom which show selectivity for P-type channels are ω-agatoxin IVA and ω-agatoxin IVB.
