Bumetanide reduces GDP event frequency and hyperpolarizes neurons to decrease the depolarizing driving force for GABA.
It is able to shorten the action potential duration in both PV and LA cells but significantly hyperpolarizes the resting membrane potential and increases dV/[dt.

This action hyperpolarizes the neurons and muscle fibers, leading to flaccid paralysis and insect death (Cully et al.
Hypokalemia hyperpolarizes the skeletal muscle cells impairing their ability to develop the depolarization, which is necessary for muscle contraction.
EDHF is thought to be a cytochrome P450-derived arachidonic acid metabolite that hyperpolarizes vascular smooth muscle cells by opening [Ca.
