What alternative medications can be used for a patient experiencing adverse effects from Glipizide and Amlodipine?

Alternative Medications for a Patient with Adverse Effects from Glipizide and Amlodipine

For this patient experiencing whole body swelling and pain from glipizide and amlodipine, switch to a DPP-4 inhibitor for diabetes management and an angiotensin receptor blocker (ARB) for hypertension control.

Diabetes Management Alternatives

Current Issues

• Patient is experiencing adverse effects from glipizide (a sulfonylurea) 1
• Patient is already on metformin 1000 mg twice daily (not taking) and has glimepiride 1 mg listed (not taking) 1

Recommended Alternatives for Glipizide

• DPP-4 inhibitors (sitagliptin, linagliptin) are recommended alternatives:

  • Do not cause hypoglycemia when used alone 1
  • Have neutral effect on weight (unlike sulfonylureas which cause weight gain) 1
  • Can be used in patients with renal impairment with appropriate dose adjustments (except linagliptin which requires no adjustment) 1

• GLP-1 receptor agonists are another option:

  • Promote weight loss rather than weight gain 1
  • Have low risk of hypoglycemia 1
  • Some can be used in renal impairment with dose adjustment 1

• SGLT2 inhibitors (empagliflozin, dapagliflozin):

  • Reduce HbA1c by 0.5-1.0% 1
  • Promote weight loss and lower blood pressure 1
  • Reduce risk of cardiovascular events and heart failure hospitalization 1

Medication to Avoid

• Glyburide should be avoided in patients with renal impairment 1
• Thiazolidinediones (glitazones) should be avoided in patients with heart failure 1

Hypertension Management Alternatives

Current Issues

• Patient is experiencing whole body swelling from amlodipine 1
• Peripheral edema is a common side effect of dihydropyridine calcium channel blockers like amlodipine 1

Recommended Alternatives for Amlodipine

• Continue losartan (patient is already taking losartan 50 mg):

  • ARBs are effective antihypertensives 1
  • Do not cause edema like calcium channel blockers 1
  • May need dose optimization - can be increased to 100 mg daily if needed 1

• ACE inhibitors (if ARB not sufficient):

  • Similar efficacy to ARBs 1
  • Do not cause edema 1
  • Patient has lisinopril 10 mg listed as "not taking" - could be restarted if appropriate 1
  • Note: Do not combine ACE inhibitors with ARBs due to increased risk of renal dysfunction and hyperkalemia 1

• Beta blockers (patient is already on carvedilol 6.25 mg):

  • Consider optimizing dose if blood pressure remains uncontrolled 1
  • Carvedilol has both alpha and beta blocking properties 1

Implementation Plan

1. For diabetes management:

   • Discontinue glipizide 1
   • Start a DPP-4 inhibitor (e.g., linagliptin 5 mg daily) 1
   • Restart metformin if not contraindicated (patient has it listed but is "not taking") 1

2. For hypertension management:

   • Discontinue amlodipine 1
   • Continue losartan and optimize dose if needed (up to 100 mg daily) 1
   • Continue carvedilol and optimize dose if needed 1
   • Consider adding a thiazide diuretic if additional BP control is needed 1

Monitoring Recommendations

• Monitor blood pressure regularly to ensure adequate control 1
• Check renal function and electrolytes, particularly if increasing losartan dose 1
• Monitor blood glucose levels to ensure adequate glycemic control with the new regimen 1
• Watch for resolution of edema symptoms after discontinuing amlodipine 1

Precautions

• Avoid combination of ACE inhibitors and ARBs due to increased risk of renal dysfunction 1
• Be aware that DPP-4 inhibitors may cause joint pain in some patients 1
• If using SGLT2 inhibitors, monitor for urinary tract infections and genital mycotic infections 1
• When switching antihypertensive medications, ensure blood pressure remains controlled during the transition 1
