| Research Abstract |
Local anesthetics are supposed to produce anesthetic action by inhibiting a neuronal sodium channel, but this inhibition cannot explain all the effects of the local anesthetic and various kinds of adverse effect. Several kinds of Ca - and Mg-ATPase were present in rat brain, but in this study, the local anesthetic inhibited Ca - Mg-ATPase activity that work in alkaline pH. Also, local anesthetic with strong anesthetic effects strongly inhibited Na,K-ATPase activity. These ATPases may be associated with effects of the local anesthetic.
