How Diabetic Nephropathies Medications Work

Diabetic nephropathies, a complication of diabetes mellitus, is characterized by kidney damage and progressive loss of renal function. The primary goal of treatment is to slow the progression of kidney damage.

Gold Standard Treatment: Angiotensin-Converting Enzyme Inhibitors (ACE inhibitors)

The gold standard for treating diabetic nephropathies is ACE inhibitors, which work by:

• Inhibiting the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor

• Reducing blood pressure and decreasing glomerular filtration rate (GFR) decline

• Slowing kidney damage progression and reducing proteinuria

Alternatives and Adjuncts

For patients who cannot tolerate ACE inhibitors, alternatives include:

• Calcineurin inhibitors, which can be used as a second-line treatment for resistant hypertension or severe kidney disease

• Direct Renin Inhibitors, an alternative for patients with resistant hypertension who cannot tolerate ACE inhibitors

Monitoring and Diagnostic Tests

Regular monitoring of kidney function is essential, including:

• Urine Albumin-to-Creatinine Ratio (ACR) test to assess proteinuria

• Serum Creatinine level measurement to monitor GFR decline

• Estimated Glomerular Filtration Rate (eGFR) calculation to track kidney function over time
