Parethoxycaine hydrochloride is an anesthetic with nerve conduction blocking activity. Parethoxycaine hydrochloride exhibits non-selective inhibitory effects on responses to various stimulants in rat vas deferens and guinea pig ileum muscles. Parethoxycaine hydrochloride has an enhanced effect on the action of norepinephrine, and its methyl bromide derivative also exhibits the same properties on the action of norepinephrine and potassium ions. Derivatives of parethoxycaine hydrochloride have significant effects on calcium dose-response curves, displaying different tissue and stimulant selectivities. The mechanism of action of Parethoxycaine hydrochloride involves the regulation of calcium transport processes[1].
