Oral agents for acute severe hypertension in children with minimal or no symptoms

Acute hypertension is common among children admitted to hospital, and large or rapid increases in blood pressure place children at risk of complications such as posterior reversible encephalopathy syndrome. Guidelines in the United States and Europe now include definitions guiding the identification of acute severe hypertension (otherwise known as hypertensive crisis) and its management. This review discusses these recommendations and the appropriate use of oral antihypertensive agents for children with minimal or no symptoms. We focus on the role of oral calcium channel blockers, including isradipine (a second‐generation dihydropyridine), given recent changes to regulatory approvals in Australia. The differing pharmacokinetic and pharmacodynamic properties of agents are compared, with the aim of facilitating directed drug selection and dosing.
