How to manage a patient with diabetes, hypertension, and cardiovascular disease on multiple medications, including insulin, anticoagulants, and pain medications?

Managing Complex Polypharmacy in a Patient with Diabetes, Hypertension, and Cardiovascular Disease

This patient requires immediate medication reconciliation with systematic deprescribing to reduce polypharmacy-related harm, prioritizing cardiovascular protection while eliminating dangerous drug combinations and redundant therapies. 1

Critical Immediate Actions

Identify and Eliminate Dangerous Medication Combinations

• Stop ibuprofen immediately – NSAIDs are contraindicated in patients on anticoagulation (Eliquis) due to dramatically increased bleeding risk, particularly hemorrhagic stroke 1. The combination of NSAID + anticoagulant + antiplatelet (aspirin) creates unacceptable bleeding risk.

• Discontinue aspirin – Dual antiplatelet therapy (aspirin + clopidogrel) combined with anticoagulation (Eliquis) constitutes triple antithrombotic therapy, which significantly increases major bleeding without proven benefit in this patient with atrial fibrillation already on therapeutic anticoagulation 1.

• Replace diclofenac gel with acetaminophen only – Topical NSAIDs still carry systemic absorption and bleeding risk when combined with anticoagulation 1. The patient already has acetaminophen prescribed; optimize this as the sole analgesic.

Address Suboptimal Cardiovascular Medication Dosing

• Increase carvedilol from 25mg (4 tablets of 6.25mg) twice daily to target dose of 50mg twice daily – Current dosing is below guideline-recommended target for heart failure with reduced ejection fraction, and beta-blockers reduce mortality in post-MI patients 1.

• Uptitrate prazosin cautiously or consider discontinuation – Prazosin 1mg three times daily provides minimal blood pressure benefit and increases fall risk in polypharmacy. If used for PTSD/nightmares, continue; otherwise eliminate 1.

• Optimize ACE inhibitor/ARB therapy – The patient is on losartan 25mg daily, which is a subtherapeutic dose. Increase to losartan 100mg daily or switch to an ACE inhibitor at target dose for superior cardiovascular and renal protection in diabetic patients 1, 2.

Rationalize Insulin Regimen

• Consolidate insulin therapy – The patient is on Novolin N 28 units daily, Novolin N 15 units evening, Novolin R sliding scale three times daily, and Novolin R 4 units twice daily. This creates four separate insulin administrations with high complexity and error risk 3.

• Simplify to basal-bolus regimen – Transition to once-daily long-acting basal insulin (glargine or degludec) plus rapid-acting insulin (aspart or lispro) with meals only, eliminating the sliding scale approach which increases hypoglycemia risk 3.

• Monitor for hypoglycemia intensively – ACE inhibitors, beta-blockers, and multiple other medications increase hypoglycemia risk; beta-blockers mask hypoglycemic symptoms 3, 4.

Systematic Medication Review Using Team Approach

Assess Each Medication for Necessity and Harm

Cardiovascular Protection (Continue/Optimize):

• Eliquis 5mg twice daily – Continue for atrial fibrillation stroke prevention 1
• Clopidogrel 75mg daily – Discontinue (redundant with anticoagulation, increases bleeding) 1
• Atorvastatin 40mg daily – Continue for ASCVD secondary prevention 1
• Carvedilol – Increase dose as above 1
• Amlodipine 10mg daily – Continue for blood pressure control 1
• Losartan – Increase dose to 100mg daily 1, 2

Diabetes Management (Simplify):

• Consolidate insulin regimen as above 3
• Consider adding SGLT2 inhibitor (empagliflozin or dapagliflozin) for cardiovascular and renal protection in diabetic patient with heart failure and CKD 1, 5

Gastroprotection:

• Omeprazole 20mg daily – Continue given anticoagulation use 1

Gout Management:

• Allopurinol 300mg daily – Continue but monitor renal function; may need dose adjustment 1

Other Medications:

• Sulfasalazine 500mg twice daily – Clarify indication; if for inflammatory arthritis, continue; if unclear indication, consider discontinuation 1
• Folic acid 1mg daily – Continue if on sulfasalazine 1
• Iron 325mg daily – Continue if documented iron deficiency 1
• Vitamin D3 800 units daily – Continue 1
• Capsaicin cream – Continue as non-systemic analgesic alternative 1

Blood Pressure and Glycemic Targets

Blood Pressure Management

• Target BP <130/80 mmHg in this diabetic patient with cardiovascular disease 1, 2
• Current regimen after optimization (losartan 100mg, carvedilol 50mg twice daily, amlodipine 10mg) should achieve target 1
• Monitor for orthostatic hypotension given multiple BP medications and autonomic neuropathy risk in diabetes 1, 5

Glycemic Control

• Target HbA1c 7.5-8% is appropriate given multiple comorbidities, cardiovascular disease, and hypoglycemia risk 5
• Avoid aggressive glycemic targets that increase hypoglycemia in patients on beta-blockers and multiple medications 1, 5

Monitoring Requirements

Laboratory Surveillance

• Check serum creatinine, eGFR, and potassium within 1-2 weeks after ACE inhibitor/ARB dose increase 1, 2
• Recheck at least every 3-6 months or with any medication changes 1, 2
• Monitor for hyperkalemia risk with combination of ACE inhibitor/ARB, beta-blocker, and potential SGLT2 inhibitor 1, 3

Clinical Monitoring

• Assess for orthostatic vital signs at every visit – measure BP supine and after 1-3 minutes standing 1, 5
• Screen for bleeding complications given anticoagulation therapy 1
• Monitor for signs of heart failure decompensation – weight, edema, dyspnea 1

Common Pitfalls to Avoid

Prescribing Cascade Prevention

• Do not add medications to treat side effects of other medications without first considering deprescribing the offending agent 1
• Example: Adding antiemetics for SGLT2 inhibitor-related nausea rather than dose adjustment 1

Drug-Drug Interaction Vigilance

• Never combine ACE inhibitor with ARB – this increases adverse events including hyperkalemia, syncope, and acute kidney injury without benefit 2
• Avoid NSAIDs entirely in patients on anticoagulation 1
• Beta-blockers mask hypoglycemia symptoms – educate patient on atypical hypoglycemia presentations 3, 4

Renal Dose Adjustments

• Adjust medications for declining kidney function – many of this patient's medications require dose modification with CKD progression 1
• Metformin should be discontinued if eGFR <30 mL/min/1.73m² to prevent lactic acidosis 5

Medication Reconciliation Errors

• Use single pharmacy when possible to enable comprehensive interaction screening 1
• Reconcile medications at every encounter – polypharmacy patients average one significant drug problem per five medications 1

Simplified Final Regimen

After systematic deprescribing, the patient should be on:

1. Eliquis 5mg twice daily
2. Atorvastatin 40mg daily
3. Carvedilol 50mg twice daily (uptitrated)
4. Amlodipine 10mg daily
5. Losartan 100mg daily (increased)
6. Simplified basal-bolus insulin regimen
7. SGLT2 inhibitor (add for CV/renal protection)
8. Omeprazole 20mg daily
9. Allopurinol 300mg daily
10. Acetaminophen 650mg three times daily as needed for pain
11. Capsaicin cream as needed
12. Sulfasalazine (if indicated), folic acid, iron, vitamin D3

This reduces medication count from 20 to approximately 12-15 medications while improving safety and maintaining therapeutic benefit. 1
