A multiattribute-utility-function approach to weighing the risks and benefits of pharmaceutical agents
1Graduate School of Management, University of California, Irvine.
Summary
This study introduces a novel method for drug dosage selection by quantifying the risk-benefit ratio. It combines human efficacy and toxicity data with animal toxicity information to optimize pharmaceutical development.
Area of Science:
- Pharmacology
- Biostatistics
- Ophthalmology
Background:
- Traditional drug dosage selection relies on a non-quantified risk-benefit ratio.
- Comparing drug toxicity and efficacy is challenging due to data heterogeneity.
Purpose of the Study:
- To develop a quantitative approach for weighing risks and benefits in pharmaceutical development.
- To create a multiattribute utility function for ophthalmic drug dosage selection.
Main Methods:
- Combined utility functions for human efficacy and toxicity.
- Integrated animal and laboratory toxicity data.
- Developed a multiattribute utility function for I-bunolol.
Main Results:
- Demonstrated a method for comparing expected utilities across different drug doses.
- Successfully applied the multiattribute utility function to I-bunolol for glaucoma treatment.
- Showcased the value of the approach in drug-dosage selection.
Conclusions:
- The proposed multiattribute utility function provides a quantifiable method for risk-benefit assessment.
- This approach enhances the precision of drug-dosage selection in pharmaceutical research.
- The methodology is applicable to other pharmaceutical agents and therapeutic areas.
