Olvanil is one capsaicin analog, which acts as an agonist at the vanilloid receptor. Olvanil may have causes an anxiogenic-like effect. Doses of 0, 0.2, 1.0 and 5.0 mg/kg Olvanil, respectively, yielded percent open arm entries at 5 min of 25±10.1, 19.3±7.1, 14.9±5.9 and 0±0[3]. Animal Model: Sprague-Dawley rats weighing approximately 200 g[3] Dosage: 0, 0.2, 1.0 and 5.0 mg/kg Administration: Injected intraperitoneally 30 min before the behavioral tests Result: The percent open arm times at 5 min were 12.9±8.1 for the 0 mg/kg dose, 8.9±4.2 for the 0.2 mg/kg dose, 15.2±7.9 for the 1 mg/kg dose and 0±0 for the 5 mg/kg dose. The mean number of entries into the closed arm at 5 min were 1.7±0.3, 3.3±0.8, 2.7±0.3 and 0.25±0.1 for doses of 0, 0.2, 1 and 5 mg/kg, respectively.
