Management of Hypertension in Patients with Orthostatic Hypotension

Introduction to Orthostatic Hypotension Management

The European Society of Cardiology recommends addressing orthostatic hypotension before intensifying blood pressure therapy, as orthostatic hypotension is a contraindication to intensifying BP therapy without first addressing the postural BP drops 1, 2
Dihydropyridine calcium channel blockers like amlodipine can worsen orthostatic hypotension through peripheral vasodilation, particularly in elderly patients 3

The European Society of Cardiology guidelines recommend confirming orthostatic hypotension by measuring BP after 5 minutes sitting/lying, then at 1 and 3 minutes after standing 1, 2
Verify medication adherence as non-adherence is the most common cause of apparent treatment failure 5

Pursue non-pharmacological approaches as first-line treatment for orthostatic hypotension in patients with supine/seated hypertension, including increasing fluid intake, compression stockings, and elevating the head of bed 30 degrees 1, 2
The European Society of Cardiology recommends switching amlodipine to an alternative BP-lowering agent that is less likely to worsen orthostatic hypotension, such as RAS inhibitors (ACE-I/ARB), rather than simply de-intensifying or increasing the dose 1, 2
Avoid beta-blockers unless compelling indications exist, as they can worsen orthostatic hypotension and are not preferred in elderly frail patients 1, 2

Elderly patients have a higher risk of adverse effects and require more gradual initial doses and titration 6
Patients with CKD3B have an increased risk of electrolyte disturbances if diuretics are added 3
Fall risk is significantly elevated in patients with Alzheimer's disease, making orthostatic hypotension particularly dangerous 4

Measure orthostatic BP at every visit (sitting/lying for 5 minutes, then standing at 1 and 3 minutes) 1, 2
Monitor for peripheral edema, the most common side effect of amlodipine 6
Assess fall risk at each visit given Alzheimer's disease and orthostatic hypotension 4
Check renal function and electrolytes given CKD3B 3
Schedule follow-up within 2-4 weeks after any medication change in this high-risk patient 5
