It has been shown that relaxation of carbachol-precontracted rat anococcygeous muscle occurs through the binding of<unk>  to sodium channels, suggesting that<unk>  has a muscle relaxation effect.<unk>  produces the effects by mediating the activation of nitrergic nerve fibers, most likely via an effect on presynaptic sodium channels. Muscle relaxation effects also arise in rabbit corpus cavernosum, but the mechanisms are not sodium channel-mediated and not completely elucidated yet.
