1.2. Pediatrics

Candesartan is FDA-approved to manage hypertension in children 1 to less than 17 years of age [1,2,4]. In 2021, the FDA expanded approval of valsartan to include patients 1 to 5 years of age for treatment of hypertension [1,2,9]. Losartan, olmesartan, and valsartan oral solution are FDA-approved to manage hypertension in pediatric patients 6 years of age and older [1,2,6,7,10]. Irbesartan is not FDA-approved for use in pediatric patients and has not demonstrated sustained efficacy in managing elevated blood pressure in patients 6 years of age and older [1,2,5]. The safety and efficacy of azilsartan and telmisartan in pediatric patients have not been established [1-3,8]. The safety and efficacy of ARBs in combination with hydrochlorothiazide, aliskiren, or amlodipine in pediatric patients have not been established.  Sacubitril/valsartan is FDA-approved to treat symptomatic heart failure with left ventricular systolic dysfunction in children 1 year and older [1,2,12]. Recommended dosages are summarized in Table 3. Dosages exceeding these recommendations will be reviewed.
