[Estimation of kidney function to adjust drug dosing].

Area of Science:

• Pharmacology
• Nephrology
• Clinical Pharmacy

Background:

• Drug dosing adjustments are crucial for patients with impaired renal function to prevent adverse effects.
• Estimating renal function typically relies on creatinine clearance or equations predicting glomerular filtration rate (GFR).

Approach:

• This review critically analyzes various methods for adjusting drug dosages based on estimated GFR.
• Comparative performance of different GFR estimation techniques for optimizing drug dosing is examined.

Key Points:

• Accurate GFR estimation is essential for safe and effective drug therapy in renal impairment.
• Different GFR equations exhibit varying accuracy, impacting dose adjustment recommendations.
• Understanding the nuances of GFR estimation is key to avoiding drug toxicity.

Conclusions:

• Provides evidence-based recommendations for drug dosing in both chronic and acute renal dysfunction.
• Highlights the importance of selecting appropriate GFR estimation methods for clinical practice.
• Aims to improve patient outcomes through optimized pharmacotherapy in renal disease.
