Lack of effect of amisulpride on the pharmacokinetics and safety of lithium.

Lithium may be used as adjuvant therapy in schizophrenic patients and antipsychotics can be employed during the early phases of lithium therapy in patients with bipolar disorder. The issue of interactions between lithium and antipsychotics is therefore important. This study investigates the potential influence of repeated administration of amisulpride, an atypical antipsychotic, on the pharmacokinetics of lithium at steady state.
