What is the optimal medication management plan for a 78-year-old patient with hypertension (controlled), type 2 diabetes (A1c 7.8%), mild knee osteoarthritis, early cataracts, and frailty, currently taking amlodipine, metformin, simvastatin, paracetamol (as needed), vitamin B12 supplement (without documented deficiency), and trimetazidine (without history of angina), presenting with unintentional weight loss, postural hypotension, and reduced mobility?

Medication Review Using Beers Criteria for 78-Year-Old Patient with Frailty

Immediate Medication Discontinuations

Trimetazidine must be discontinued immediately as there is no documented history of angina or other indication for antianginal therapy, making this medication entirely inappropriate and potentially harmful. 1

Vitamin B12 supplement should be discontinued as there is no documented deficiency, and studies show that vitamin and mineral supplements without specific indications add complexity and cost without evidence of preventive benefits including mortality, cardiovascular disease, cancer, or cognitive function. 1

Critical Blood Pressure Management Issue

Amlodipine requires immediate dose reduction or discontinuation given the documented postural hypotension (BP drop from 135/80 sitting to 120/75 standing) in this frail patient with two falls in the past year. 1, 2

• The European Society of Cardiology explicitly states that for patients with pre-treatment symptomatic orthostatic hypotension, BP-lowering treatment should only be considered from ≥140/90 mmHg, and this patient's sitting BP of 135/80 is below this threshold. 1
• Reduce amlodipine from current dose to 2.5-5 mg daily or consider discontinuation entirely given the orthostatic hypotension and fall risk. 2, 3
• Long-acting dihydropyridine CCBs like amlodipine are preferred agents when antihypertensive therapy is necessary in patients with orthostatic hypotension, but the dose must be carefully titrated. 1, 3
• Recheck blood pressure within 2-4 weeks after dose adjustment, specifically monitoring for orthostatic changes (measure after 5 minutes sitting/lying, then at 1 and 3 minutes after standing). 2, 3

Diabetes Management Concerns

Metformin requires careful monitoring but can be continued with the following caveats:

• The A1c of 7.8% is acceptable for this frail 78-year-old patient; guidelines suggest relaxing glycemic goals in frail elderly patients. 1
• Target A1c should be 7.5-8.5% for this patient given her frailty status (FRAIL score 3/5), fall risk, and limited life expectancy. 1
• Monitor renal function closely as metformin requires dose adjustment or discontinuation if eGFR falls below certain thresholds. 1
• The unintentional 3 kg weight loss over 4 months is concerning and may be related to diabetes control or other factors requiring investigation. 4

Statin Therapy Assessment

Simvastatin should be continued as cardiovascular benefit continues to be conferred in patients older than 80 years compared with those who do not take statin therapy. 1

• Discontinuing statins in adults older than 75 years with no previous cardiovascular disease increases risk by 1.33 (95% CI, 1.18 to 1.50) for any cardiovascular event. 1
• However, monitor for muscle-related adverse effects given the mild muscle wasting in calves noted on exam. 1

Paracetamol (Acetaminophen) PRN

Paracetamol can be continued as needed for osteoarthritis pain management, as it is not listed in the Beers Criteria as potentially inappropriate. 5

• Ensure the patient is not using NSAIDs concurrently, as these are potentially inappropriate in older adults and increase fall risk. 6, 5
• Maximum daily dose should not exceed 3000 mg in elderly patients to minimize hepatotoxicity risk. 1

Blood Pressure Target Adjustment

Target BP should be 140/90 mmHg or "as low as reasonably achievable" (ALARA principle) given this patient's age ≥85 years equivalent risk profile (frailty, orthostatic hypotension, fall history). 1, 2

• The European Society of Cardiology recommends that for patients with pre-treatment symptomatic orthostatic hypotension, clinically significant moderate-to-severe frailty, BP-lowering treatment should only be considered from ≥140/90 mmHg. 1
• Current sitting BP of 135/80 with orthostatic drop suggests the patient is over-treated. 2, 3

Monitoring and Follow-Up Protocol

Implement the following monitoring schedule:

• Orthostatic vital signs at every visit (measure after 5 minutes sitting, then at 1 and 3 minutes standing). 1, 3
• Renal function and electrolytes every 3-6 months given metformin use. 1
• A1c every 3-6 months, targeting 7.5-8.5%. 1
• Fall risk assessment at each visit using validated tools. 1, 6
• Medication reconciliation every 3-6 months to reassess need for each medication. 1

Deprescribing Strategy Summary

Total medications reduced from 7 to 4:

1. DISCONTINUE: Trimetazidine (no indication)
2. DISCONTINUE: Vitamin B12 (no documented deficiency)
3. REDUCE DOSE: Amlodipine (orthostatic hypotension, fall risk)
4. CONTINUE: Metformin (with relaxed A1c target)
5. CONTINUE: Simvastatin (proven benefit in elderly)
6. CONTINUE: Paracetamol PRN (appropriate for OA)

Critical Pitfalls to Avoid

• Do not target BP <130/80 mmHg in this frail elderly patient with orthostatic hypotension and fall risk. 1, 2
• Do not add additional antihypertensive agents at this time, as the issue is over-treatment, not under-treatment. 2, 3
• Do not intensify diabetes therapy to achieve A1c <7.5% in this frail patient, as this increases hypoglycemia risk without mortality benefit. 1
• Do not simply de-intensify BP therapy without switching to alternative agents if BP control is still needed; instead, optimize the dose of the preferred agent (amlodipine). 1, 3
• Do not prescribe anticholinergic medications (diphenhydramine, oxybutynin, cyclobenzaprine) if symptoms arise, as these are strongly associated with falls, cognitive decline, and functional impairment in frail elderly patients. 1, 6
