Disposition of enantiomers of sultopride in a human, rats and rabbits.

Pharmacokinetics of sultopride enantiomers was examined following a single dose in a human, rabbits and rats. Pharmacokinetic profiles were similar between (+)- and (-)-enantiomers of sultopride in human, whereas the serum concentrations of (-)-sultopride were slightly higher than those of (+)-sultopride after i.v. administration of 50 mg/kg of racemic sultopride to rats and rabbits.
