JF Drug Metabolism and Disposition JO Drug Metab Dispos FD American Society for Pharmacology and Experimental Therapeutics SP 114 OP 119 VO 6 IS 2 A1 U Breyer-Pfaff A1 H Kreft A1 H Rassner A1 A Prox YR 1978 UL http://dmd.aspetjournals.org/content/6/2/114.abstract AB Didesmethylchlorpromazine sulfone [gamma-(2-chlorophenothiazinyl-10)-propylamine sulfone] has been isolated from the urine of a patient under continuous chlorpromazine therapy and identified by mass spectrometry. The same compound was present in organs of rats after injection of the corresponding sulfide. The Cl-free analogue, gamma-(phenothiazinyl-10)-propylamine sulfone, was excreted by patients receiving perazine and by a volunteer after ingestion of the primary amine sulfoxide.
