Description
Sources: http://www.eisai.jp/medical/products/di/EPI/SR_T-G_EPI.pdf
Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/13910333 and http://home.intekom.com/pharm/akromed/mucaines.html

Oxethazaine is a potent local anesthetic. It is administered orally (usually in combination with an antacid) for the relief of pain associated with peptic ulcer disease or esophagitis. Its effectiveness at the acidity of the gastric environment is due to the fact that oxethazaine, a weak base, is relatively non-ionized at pH 1. It is also used topically in the management of hemorrhoid pain. Oral oxetacaine preparations are available in several countries, including India, South Africa and Brazil, but not the United States. It is marketed under the name Strocain in Japan.

Sample Use Guides

In Vivo Use Guide

The usual adult dosage for oral use is 3 to 8 tablets (15 to 40 mg of oxethazaine) daily divided into three to four doses.

Route of Administration: Oral

In Vitro Use Guide

100 uM Oxethazaine caused almost complete red blood cell hemolysis in the presence of 1.3 mM Ca2+ with only a minimal effect in its absence, while higher concentrations of Oxethazaine (400 uM<) produced hemolysis without Ca2+.
