* Presence of uncontrolled diabetes with fasting glycemia ³ 200 mg/dL (³ 11.09 mmol/L)
* Patients considered by the Investigator unsuitable candidates to receive an investigational drug (e.g., presence of any neurological symptoms that may worsen in five days, based on the judgment of the Investigator, or presence of any neurological symptoms for which the persistence of hyponatremia over several days may be deleterious)
* Administration of inducers of CYP3A4 (phenobarbital, phenytoin, rifampin, Saint John's Wort) or potent and moderate inhibitors of CYP3A4 within two weeks prior to study drug administration
* Presence or history of allergic reaction to SR121463B8
* Previous study with SR121463B
* Inadequate hematological, renal, and hepatic functions: hemoglobin (Hb) < 9 g/dL, neutrophils < 1,500/mm3, platelets < 100,000/mm3, serum creatinine > 175 mol/L (or clearance of creatinine < 30 mL/min for sites where Ethics Committees require this parameter), serum alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) > 2 x upper limit of normal (ULN)
* QTCB 500 ³ ms
* Positive pregnancy test and absence of medically approved contraceptive methods (e.g., surgical sterilization of more than one month duration, oral contraception or intrauterine device in combination with either diaphragm, condom, or spermicide) for females of childbearing potential
* Pregnancy or breast-feeding
