In Vitro	Polythiazide (500 μM, 1 min) induces significant phototoxic NHIK 3025 cell death under Bluelight 2000 apparatus (Ex: 325 nM)[2].
In Vivo	Polythiazide (oral gavage, 10 mg/kg, daily for 5 days) Increased plasma cholesterol levels in Cholesterol-fed C57BL/cdJ mouse[3]. Polythiazide (Oral administration, 0.4 mg/k g) shows diuretic and saluretic effects in hypertensive dogs and rats[1]. Animal Model: Cholesterol-fed C57BL/cdJ mice[3] Dosage: 10 mg/kg Administration: Oral gavage, daily for 5 days Result: Caused approximately 13% rise in total plasma cholesterol levels, and increased non-HDL lipoprotein fraction. Animal Model: Hypertensive dogs[1] Dosage: 0.4 mg/kg Administration: Oral administration, daily for 5 days Result: Increased in excretion of sodium and chloride. Animal Model: Hypertensive rats[1] Dosage: 0.05, 0.1, 0.2, 0.4 mg/k g Administration: Oral administration, twice a day for 3 days. Result: Displayed natriuretic and chloruretic effects.
