Sodium salt of etodolic acid and process for its preparation.

摘要

The sodium salt of etodolic acid (1,8-diethyl-1,3,4,9-tetrahydropyran-[3,4-b]indol-1-acetic acid) and a process for its preparation are described. The obtained sodium salt has an appreciable solubility in water and is, therefore, suitable for preparing pharmaceutical formulations particularly fit for parenteral as well as topic and rectal administration.
