In a 67-year-old male nursing home resident taking amlodipine 10 mg daily and metoprolol tartrate 50 mg twice daily, whose antihypertensive medications are being held intermittently due to hypotension, what medication adjustments should be made?

Medication Adjustment Recommendations for Hypotension in an Elderly Nursing Home Resident

Reduce or discontinue amlodipine first, as calcium channel blockers are a common cause of hypotension in older adults and amlodipine 10 mg is at maximum dose, while metoprolol should generally be continued if there is a compelling indication (heart failure, post-MI, or coronary disease) but reduced if used solely for hypertension. 1

Prioritize Amlodipine Reduction

• Amlodipine is the primary medication to adjust because calcium channel blockers frequently cause hypotension, dizziness, and falls in elderly patients, particularly those in nursing homes 1
• The patient is on the maximum dose (10 mg daily), leaving no room for upward titration but significant opportunity for reduction 2
• In elderly patients (>65 years), amlodipine clearance is decreased by 40-60%, resulting in higher drug levels and increased risk of hypotension 2
• Reduce amlodipine to 5 mg daily initially, monitoring blood pressure closely over 1-2 weeks 1
• If hypotension persists after dose reduction, discontinue amlodipine entirely 1

Evaluate Metoprolol Continuation Based on Indication

If Metoprolol Has a Compelling Indication:

• Continue metoprolol if prescribed for heart failure with reduced ejection fraction, post-myocardial infarction, or coronary artery disease, as beta-blockers reduce mortality in these conditions 1
• If hypotension occurs with compelling indications present, reduce metoprolol tartrate to 25 mg twice daily rather than discontinuing 1
• Guidelines specifically state to "reduce the dose of beta-blockers if necessary, but discontinue only if clearly necessary" when hypotension occurs 1

If Metoprolol Is Used Solely for Hypertension:

• Consider discontinuing metoprolol if it was prescribed only for blood pressure control without other cardiovascular indications 1
• Beta-blockers are less effective than other antihypertensives for stroke prevention in older adults and are not first-line agents 1
• Metoprolol can cause cognitive impairment in elderly patients, which is particularly concerning in nursing home residents 1

Specific Deprescribing Strategy

Step 1: Immediate Action

• Reduce amlodipine from 10 mg to 5 mg daily 1
• Continue current metoprolol dose initially while assessing for compelling indications 1

Step 2: Monitor Over 1-2 Weeks

• Check blood pressure standing and sitting to assess for orthostatic hypotension 1
• Document frequency of hypotensive episodes requiring medication holds 1
• Assess for falls, dizziness, or syncope 1

Step 3: Further Adjustment if Needed

• If hypotension persists with amlodipine 5 mg: discontinue amlodipine completely 1, 3
• If metoprolol has no compelling indication and hypotension continues: reduce to 25 mg twice daily or discontinue 1
• If metoprolol has compelling indications: reduce to 25 mg twice daily 1

Critical Considerations for Nursing Home Residents

• 29-45% of nursing home residents are prescribed potentially inappropriate medications, with polypharmacy being a common cause of falls, cognitive impairment, and hospitalizations 1
• Antihypertensive medications are frequently held in nursing homes due to hypotension, indicating the regimen is too aggressive for the patient's current status 1
• In patients >75 years, ACE inhibitors and ARBs are considered potentially inappropriate medications when causing hypotension 1
• The OPTIMISE trial demonstrated that antihypertensive medication reduction in patients >80 years maintained blood pressure control in 86.4% of patients without significant adverse events 3

Blood Pressure Targets for This Population

• For nursing home residents with frailty, multimorbidity, or limited life expectancy, blood pressure targets should be relaxed to <150/90 mmHg rather than intensive targets 1
• Clinical judgment is reasonable for decisions regarding intensity of blood pressure lowering in older adults with high comorbidity burden 1
• Avoid intensive blood pressure targets (<130/80 mmHg) in frail elderly nursing home residents, as the risk of hypotension, falls, and functional decline outweighs cardiovascular benefits 1

Monitoring After Adjustment

• Measure blood pressure at each nursing assessment, including orthostatic measurements 1
• Document standing and recumbent blood pressure to detect orthostatic hypotension 1
• Monitor for adverse events including falls, syncope, dizziness, and cognitive changes 1
• Reassess medication regimen every 3-6 months or when clinical status changes 1, 4

Common Pitfall to Avoid

Do not continue both medications at current doses simply because blood pressure readings are occasionally elevated. Intermittent medication holds by nursing staff indicate the regimen is causing symptomatic hypotension, which increases fall risk, fractures, and acute kidney injury in elderly nursing home residents 1. The priority is preventing hypotension-related morbidity rather than achieving aggressive blood pressure targets in this frail population 1.
