Abstract

The influences of emotional changes induced by being exposed to a new environment on the pharmacokinetics of plasma drug concentration were studied in male Wistar rats. Transfer from a familiar home cage to a new home cage was considered to induce psychological (non-physical) emotional changes. First, nicorandil and zonisamide, drugs that act on the peripheral system and central nervous systems, were used, respectively. Immediately after oral administration of nicorandil (10 mg/kg) or zonisamide (50 mg/kg), the animals were transferred to new home cages. Plasma nicorandil and zonisamide concentrations were determined by high-performance liquid chromatography at 1 and 4 h after administration. Plasma nicorandil concentration in the group transferred to new home cages was significantly decreased relative to levels in the non-transferred control group. However, zonisamide concentrations were unchanged. These findings suggest that the pharmacokinetics of nicorandil, but not those of zonisamide, tend to be influenced by non-physically induced emotional changes.
