Oxotremorine (10.5 micron) produced a paralytic effect on twitch responses of rat diaphragm in vitro to direct and indirect stimulation[1].

Rats with signs of neuropathy were subjected to SCS applied in awake, freely moving condition. Oxotremorine was administered intrathecally. Tactile, cold and heat sensitivities were assessed by using von Frey filaments, cold spray and focused radiant heat, respectively. Oxotremorine i.t. dose-dependently suppressed the tactile hypersensitivity. SCS markedly increased withdrawal thresholds (WTs), withdrawal latencies and cold scores[2].
