Nomograms for drug use in renal disease

Area of Science:

• Pharmacology
• Nephrology
• Clinical Pharmacy

Background:

• Medical literature contains numerous dosing guidelines for patients with renal dysfunction.
• Adjusting drug dosages is critical for medications with a narrow therapeutic index, like digoxin and aminoglycoside antibiotics.

Purpose of the Study:

• To review various methods used for creating drug dosing nomograms.
• To address the predictability and unpredictability of achieving target drug plasma concentrations.

Main Methods:

• Review of existing literature on drug dosing in renal impairment.
• Analysis of different approaches to developing dosing nomograms.
• Discussion of factors influencing drug concentration predictability.

Main Results:

• Various methods exist for devising dosing nomograms for renal dysfunction.
• Predictability of achieving desired drug plasma concentrations varies among methods.
• No single nomogram is universally applicable to all patients.

Conclusions:

• Therapeutic drug regimens for patients with renal dysfunction must be individualized.
• Clinicians should understand the principles of dose adjustment for effective therapy planning.
• Relying solely on standardized nomograms may not be optimal for all patients.
