Time dependent effects of DZP at 10 mg/kg dose with or without TPPU on blood pressure (n=6 per group). Upon obtaining baseline BP, mice were administered TPPU (i.p., 3 mg/kg) 1 h before injection of DZP at varying dosages. Blood pressure was recorded at baseline, at 45 min after TPPU or PEG400 administration, at 5 min after DZP (10 mg/kg) and then at 1, 2, 3, 4, 5, 6 and 24 h. Data are mean ± SEM. n=6 /group.
