Pharmacological characteristics of zolmitriptan-sensitive I
. Bar graph shows that inhibition of IBa was significantly reduced with ω-Aga, compared to those with ω-CgTx and nicardipine, Aand with SNX-482, compared to that with nicardipine (*p < 0.05). IBa (control) after pretreatment with Ca2+ blockers and IBa (test) 2 min after adding zolmitriptan were recorded as indicated in the inset. IBa ratio was obtained by IBa (test)/IBa (control).
