In Vivo Repeated dosing of olmesartan (1 mg/kg, 2 mg/kg, p.o.) dose-dependently decreases mean arterial blood pressure (MAP) in SHR without significant influence on body weight and food intake during 10 weeks[1]. Olmesartan (5 mg/kg/d, p.o.) and Hyd treatments lower systolic blood pressure to the same degree in mice. Olmesartan treatment inhibits cardiac hypertrophy, evaluated by echocardiography, heart weight, cross-sectional area of cardiomyocytes, and gene expression. Olmesartan treatment reverses decreased gene expressions of ACE2 and Mas receptor of Ren-Tg mice and inhibits enhanced NADPH oxidase (Nox)4 expression and reactive oxygen species[2].
Animal Admin Seven week-old male spontaneously hypertensive rats (SHR) are divided into five groups and fed a high fat diet (HFD) (60% kcal as fat) ad libitum. SHR are treated with vehicle (1% tragacanth gum solution), telmisartan (1 mg/kg), telmisartan (2 mg/kg), olmesartan (1 mg/kg) or olmesartan (2 mg/kg) once daily by gastric gavage. After more than 4 weeks-treatment, mean arterial blood pressure is measured for 24 h under a conscious state.
