Lithium absorption, distribution and clearance and body temperature in rats given lithium plus haloperidol

Renal lithium clearance, tissue lithium levels, serum lithium concentration, and body temperature were determined in rats given lithium alone or combined with haloperidol (0.5-1 mg/kg). A slight increase in serum lithium concentration occurred in one of the three groups given lithium plus haloperidol. Haloperidol failed to affect renal lithium clearance, tissue lithium levels and body temperature. The data do not support the hypothesis that haloperidol exerts an action on lithium pharmacokinetics.
