Pharmaceutical compositions having therapeutical activity based on mercaptoethansulphonic acid

摘要

Derivatives of mercapthansulphonic acid are active in the therapy of the bladder carcinoma and in the therapy and prevention of the cistinic kidney calculi. The saline derivatives with basic aminoacids and their alkyl esters are moreover devoid of side effects. The saline derivatives are prepared by reacting, in aqueous or aqueous-alcoholic medium, equimolar amounts of mercaptoethansulphonic acid, just prepared from an organic or inorganic salt thereof, and of the desired aminoacid.
