“The alpha 1-receptor-induced hyperpolarization caused by adrenaline (3 X 10(-6) M) in the presence of mebeverine declined after reaching an initial maximum.”
“The hyperpolarization induced by a second addition of adrenaline to the preparation was decreased and sustained in the presence of mebeverine , while the decrease of the electrotonic potential evoked during the alpha 1 response was less pronounced.”
