In Vitro	Tazanolast, an orally active mast-cell-stabilizing drug, which has been shown to suppress passive cutaneous anaphylaxis, Schultz-Dale reaction in isolated tracheal muscle, and experimental asthma without antagonistic actions upon histamine- and leukotriene-D4-induced contraction, IgE-mediated or compound 48/80-induced histamine release from mast cells and lung fragments, compound 48/80-induced Ca2+ uptake into mast cells from extracellular medium, compound 48/80-induced translocation of protein kinase C from the cytosol to the membrane fraction of mast cells, and inositol trisphosphate production without directly inhibiting phospholipase C in mast cells[1].
In Vivo	Tazanolast administered before ozone exposure at doses of 30, 100, or 300 mg/kg inhibits ozone-induced airway hyperresponsiveness in a dose-dependent manner. Tazanolast administered after ozone exposure does not inhibit the airway hyperresponsiveness. Tazanolast does not significantly change the cell distribution of bronchoalveolar lavage (BAL) cells at 2 h after the exposure. Tazanolast significantly inhibits ozone-induced airway hyperresponsiveness in guinea pigs[1].
Animal Admin	Pigs[1] The 10 guinea pigs are also exposed to 2 ppm ozone for 2 h and then are orally administered 300 mg/kg of Tazanolast (T-300 post group). At 2 h after exposure PC200-MCh of each animal is determined. Thereafter, BAL is performed for each animal. On Day 1, preexposure PC200-MCh is determined for 50 guinea pigs. On Day 2, guinea pigs in groups of 10 are orally administered Tazanolast at a dose of 30 mg/kg (T-30 group), 100 mg/kg (T-100 group), or 300 mg/kg (T-300 group), or vehicle alone (vehicle group). After 30 min, the animals are exposed to 2 ppm ozone for 2 h. In addition, the other 10 guinea pigs are also exposed to 2 ppm ozone for 2 h and then are orally administered 300 mg/kg of Tazanolast (T-300 post group). At 2 h after exposure PC200-MCh of each animal is determined. Thereafter, BAL is performed for each animal.
