    This study introduces a new method for analyzing competitive antagonists using the odds ratio (OR) instead of the equi-effective dose ratio (DR). This approach offers a more cost-effective and time-efficient alternative to existing procedures.

    Area of Science:

    • Pharmacology
    • Biostatistics

    Context:

    • Analyzing competitive antagonist activity is crucial in drug development.
    • Existing methods like the Arunlakshana and Schild equation can be resource-intensive.

    Purpose:

    • To propose a novel, more economical procedure for analyzing competitive antagonists.
    • To establish the validity of using the odds ratio (OR) as a substitute for the equi-effective dose ratio (DR).

    Summary:

    • A new procedure is presented that utilizes the odds ratio (OR) under fixed agonist concentrations to analyze competitive antagonists.
    • The odds ratio (OR) is demonstrated to be equivalent to the equi-effective dose ratio (DR) under fixed effects, allowing for its substitution in the Ainsworth-Schild (A-S) equation.
    • This method simplifies antagonist analysis by replacing the more complex DR calculation with the more accessible OR.
