Who needs molar units for drugs?

Area of Science:

• Clinical pharmacology
• Pharmaceutical science
• Medical laboratory science

Background:

• Current drug concentration measurements in clinical medicine lack standardization.
• The need for a unified system to ensure patient safety and treatment efficacy is critical.

Purpose of the Study:

• To evaluate the necessity and feasibility of standardizing drug concentration units in clinical medicine.
• To assess the implications of adopting molar units versus retaining mass units for drug measurements.

Main Methods:

• Literature review and critical analysis of current practices in drug concentration measurement.
• Evaluation of the potential impact of unit standardization on clinical workflows, patient safety, and economic factors.

Main Results:

• Mass units (e.g., mg/L) are deemed the most practical and safe choice for drug concentration measurement.
• Transitioning to molar units would introduce significant disruption, inconvenience, and potential patient danger.
• There is no clear benefit for clinicians or patients in adopting molar units for drugs.

Conclusions:

• Mass units should be retained for drug concentration measurements in clinical medicine.
• Proposals for adopting molar units should be abandoned due to lack of benefit and potential risks.
• Standardization using mass units is essential for safe and effective clinical practice.
