Description

Curator's Comment: description was created based on several sources, including http://www.kiessig.com/drugs/druginfo.aspx?id=1218 | http://www.kiessig.com/drugs/druginfo.aspx?id=1218 | https://www.ncbi.nlm.nih.gov/pubmed/8799190 | https://www.ncbi.nlm.nih.gov/pubmed/8085162

Etidocaine, marketed under the trade name Duranest, is a local anesthetic given by injection during surgical procedures and labor and delivery. Etidocaine has a long duration of activity, and the main disadvantage of using during dentistry is increased bleeding during surgery. Etidocaine stabilizes the neuronal membrane by inhibiting the ionic fluxes required for the initiation and conduction of impulses, thereby effecting local anesthetic action.

Sample Use Guides

In Vivo Use Guide

The maximum dose to be employed as a single injection should be determined on the basis of the status of the patient and the type of regional anesthetic technique to be performed. Although single injections of 450 mg have been employed for regional anesthesia without adverse effects, at present it is strongly recommended that the maximal dose as a single injection should not exceed 400 mg (approximately 8.0 mg/kg or 3.6 mg/lb based on a 50 kg person) with epinephrine 1:200,000 and 300 mg (approximately 6 mg/kg or 2.7 mg/lb based on a 50 kg person) without epinephrine.

Route of Administration: Intramuscular

In Vitro Use Guide

Rat brain type IIA Na+ channels expressed in Xenopus oocytes were stimulated infrequently (1 pulse per 20 s, all currents were elicited by 15-ms pulses to 0 mV.) This tonic block mainly reflects drug binding to resting channels, the channel state that predominated at the holding potential of -90 mV. Etidocaine (200 mkM) decrease activities of WT Type IIA Na+ channels on ~40%.
