Abstract:
The disclosure is directed to improvement of the stability of oxygen sensitive compounds. Phenothiazines may be stabilized by the use of small amounts of monothioglycerol in the marketable composition. Especially good results are obtained in the stabilization of promethazine formulations with monothioglycerol.
