Should an elderly patient with hypertension, currently taking a calcium channel blocker and losartan (angiotensin II receptor antagonist) 50 milligrams, with a blood pressure of 137/82 mmHg, have their medication increased or remain unchanged?

Blood Pressure Management Decision for Elderly Patient on Dual Therapy

Leave the medications unchanged—this patient's blood pressure of 137/82 mmHg is already at target for an elderly individual on a calcium channel blocker and losartan 50 mg, and intensifying therapy would provide no additional benefit while increasing the risk of adverse effects. 1

Current Blood Pressure Assessment

• The patient's blood pressure of 137/82 mmHg meets the recommended target of <140/90 mmHg for elderly patients, which is the minimum acceptable goal according to current guidelines 1
• For elderly patients, particularly those over 65 years, the primary target is <140/90 mmHg, with more aggressive targets (<130/80 mmHg) reserved only for high-risk patients who tolerate lower pressures well 1
• The systolic pressure of 137 mmHg is well-controlled and does not warrant treatment intensification 1

Why Not to Intensify Treatment

• The patient is already on appropriate dual therapy with complementary mechanisms of action—a calcium channel blocker providing vasodilation and losartan (an ARB) providing renin-angiotensin system blockade 2
• Losartan 50 mg is the standard starting dose for hypertension, with the option to increase to 100 mg daily if blood pressure remains uncontrolled (≥140/90 mmHg) 3
• Since this patient's blood pressure is already below 140/90 mmHg, dose escalation is not indicated 3

Treatment Algorithm for Elderly Patients

• If BP is <140/90 mmHg: Continue current regimen and monitor 1
• If BP is 140-159/90-99 mmHg: Consider optimizing current medications before adding a third agent 1
• If BP is ≥160/100 mmHg: Add a thiazide-like diuretic as the third agent to achieve guideline-recommended triple therapy 2, 1

Critical Considerations for Elderly Patients

• Elderly patients require careful monitoring for orthostatic hypotension, which becomes more likely with aggressive blood pressure lowering 1
• The combination of a calcium channel blocker and ARB is well-tolerated in elderly patients and provides effective blood pressure control without the metabolic complications associated with diuretics 4
• Overtreatment in elderly patients can lead to falls, syncope, and acute kidney injury without providing additional cardiovascular benefit when BP is already at target 1

Monitoring Recommendations

• Recheck blood pressure within 3-6 months to confirm sustained control 1
• Check blood pressure in both sitting and standing positions to screen for orthostatic hypotension 1
• Confirm readings with home blood pressure monitoring if not already done, as clinic readings may overestimate true blood pressure 2

When to Consider Adding a Third Agent

• Only if blood pressure rises to ≥140/90 mmHg on repeated measurements should you consider adding a thiazide-like diuretic (chlorthalidone 12.5 mg or indapamide 1.25 mg daily) as the third agent 2, 1
• Before adding medications, always verify adherence to current therapy and reinforce lifestyle modifications including sodium restriction to <2g/day 2
