Abstract: The present invention relates to novel noncardiotoxic compounds and pharmaceutical compositions useful in the treatment of a variety of disorders including the treatment of depression, allergies, psychoses, cancer and gastrointestinal disorders. In particular, the present invention describes pharmaceutical compositions that mitigate life-threatening arrhythmias such as torsade de pointes. Torsade de pointes is a particular cardiac problem associated with many therapeutic agents and has been implicated as a possible cause of sudden death, particularly in those individuals with a past history of disturbances of cardiac rhythm, myocardial infarction, congenital repolarization abnormalities and cardiac risk factors such as hyperlipidemia and age. This arrhythmia is a variant of paroxysmal ventricular tachycardia associated with a prolonged QTc interval or prominent U waves on the ECG.

Abstract: The present invention relates to pharmaceutical compositions containing sulpiride compounds having the general formula: where R1 is branched or straight chain alkyl having from 1 to about 7 carbon atoms, a substituted or unsubstituted aryl, a substituted or unsubstituted cycloalkyl, a substituted or unsubstituted aralkyl, a substituted or unsubstituted alkylcycloalkyl, or a group having the formula (CH2)n R2 where R2 is a substituted or unsubstituted aryl or a substituted or unsubstituted cycloalkyl, and n is an alkyl group having from 0 to about 6 carbon atoms and pharmaceutically acceptable salts or diluents.
