Medication Management for CKD with Hypertension
For patients with CKD and hypertension, start an ACE inhibitor or ARB immediately and titrate to the maximum approved dose, target blood pressure <130/80 mmHg, add an SGLT2 inhibitor if diabetic (regardless of glucose control), and initiate statin therapy for all patients. 1, 2
Blood Pressure Management
Target Blood Pressure
- Aim for BP <130/80 mmHg for all CKD patients with hypertension 1, 2
- For patients with severely elevated albuminuria (≥300 mg/g), consider targeting systolic BP 120-129 mmHg 2
First-Line Antihypertensive Therapy
ACE Inhibitors or ARBs are mandatory first-line agents for CKD patients with albuminuria (≥30 mg/g) and hypertension:
- Titrate to the highest approved tolerated dose (Grade 1B recommendation) 1, 2
- For losartan specifically: start 50 mg daily, increase to 100 mg daily as needed for BP control 3
- Start with 25 mg if volume depleted or on diuretics 3
Monitoring after ACE inhibitor/ARB initiation is critical:
- Check serum creatinine and potassium within 2-4 weeks of starting or dose changes 1
- Continue therapy unless creatinine rises >30% within 4 weeks 1
- If creatinine increases >30%, evaluate for acute kidney injury, volume depletion, renal artery stenosis, and review NSAIDs/diuretics before stopping 1
Managing Hyperkalemia
Do not immediately stop ACE inhibitors/ARBs for hyperkalemia - instead implement these strategies first: 1
- Review and stop concurrent potassium-raising medications
- Moderate dietary potassium intake
- Add diuretics if not contraindicated
- Consider sodium bicarbonate supplementation
- Use GI cation exchangers
- Only reduce dose or discontinue as last resort 1
Additional Antihypertensive Agents
When ACE inhibitor/ARB alone is insufficient:
- Add long-acting dihydropyridine calcium channel blockers (CCBs) as second-line 4, 5
- Add thiazide or loop diuretics as third-line 2, 4
- Most CKD patients require 3+ antihypertensive agents to reach target BP 1
For treatment-resistant hypertension:
- Add spironolactone (steroidal mineralocorticoid receptor antagonist) 5
- Alternative: chlorthalidone is effective in stage 4 CKD and can mitigate hyperkalemia risk 5
- Monitor potassium closely with these combinations 5
Important caveat: Non-dihydropyridine CCBs (verapamil, diltiazem) are contraindicated in heart failure with reduced ejection fraction 1
Glucose-Lowering Medications (Type 2 Diabetes)
SGLT2 inhibitors are now mandatory for all type 2 diabetics with CKD stage 3 or higher (eGFR <60 mL/min/1.73 m²):
- Initiate regardless of glycemic control - the benefit is for kidney and cardiovascular protection, not glucose lowering 1, 2, 6
- Start when eGFR ≥20 mL/min/1.73 m² 1
- Continue until dialysis or transplantation - benefits persist as eGFR declines 1, 2
- Combine with metformin when eGFR ≥30 mL/min/1.73 m² 1, 2
If additional glucose lowering needed beyond SGLT2 inhibitor + metformin:
- Add GLP-1 receptor agonist as preferred third agent 1, 2
- GLP-1 agonists reduce risk of end-stage kidney disease 7
For patients with persistent albuminuria >30 mg/g despite first-line therapy:
- Consider adding nonsteroidal mineralocorticoid receptor antagonist (finerenone) for additional kidney and cardiovascular protection 1
Lipid Management
Initiate statin therapy for ALL CKD patients - this is non-negotiable: 1, 2
- Cardiovascular disease is the leading cause of death in CKD 2
- Add ezetimibe, PCSK9 inhibitor, or icosapent ethyl based on residual ASCVD risk and lipid levels 1
Additional Medications and Monitoring
Sodium bicarbonate supplementation:
- Give oral bicarbonate if serum bicarbonate <22 mmol/L to maintain normal range (Grade 2B) 1
Antiplatelet therapy:
- Aspirin for lifelong secondary prevention in established cardiovascular disease 1
- May consider for primary prevention in high-risk individuals 1
Avoid nephrotoxic medications:
- NSAIDs (including COX-2 inhibitors) 1
- Aminoglycosides, amphotericin B 1
- High-osmolar contrast agents - use lowest dose, ensure hydration 1
Lifestyle Modifications
Dietary sodium restriction is critical and often overlooked:
Protein intake:
- Restrict to 0.8 g/kg/day when eGFR <30 mL/min/1.73 m² 1, 2
- Avoid high protein intake >1.3 g/kg/day 1, 2
- Do not restrict if malnourished 1
Mandatory interventions:
- Smoking cessation - tobacco accelerates CKD progression 2
- Regular exercise for BP control and cardiovascular outcomes 2
Follow-Up Monitoring Schedule
Intensive monitoring when:
- Systolic BP ≥140 or <120 mmHg: recheck within 4 weeks 1
- eGFR <60 mL/min/1.73 m²: recheck within 4 weeks 1
- On ACE inhibitor/ARB with potassium >4.5 mEq/L: recheck within 4 weeks 1
Once stable:
