Table 2. Potency Ratios for Effects on Airway Smooth Muscle and Anesthetic Effects
Values for airway smooth muscle effects are calculated as the ratio of EC50values for a given condition (from table 1). Values for anesthetic effects were calculated from published values for minimum alveolar concentration (MAC) in rats 12or EC50values for the righting reflex in tadpoles. 11
KCl = potassium chloride; MAC = minimum alveolar concentration.
