Background:

• Etomidate is a widely used anesthetic agent.
• Accurate quantification of etomidate in biological matrices is crucial for pharmacokinetic and pharmacodynamic studies.
• Existing analytical methods may be complex or time-consuming.

Purpose of the Study:

• To develop and validate a simplified and effective LC assay for etomidate quantitation in beagle plasma.
• To establish a reliable method for preclinical etomidate analysis.
• To improve the efficiency of etomidate level determination.

Main Methods:

• Development of a rapid protein precipitation technique.
• Utilized previously established chromatographic conditions for separation.
• Quantification using Liquid Chromatography (LC) in beagle plasma samples.

Main Results:

• The assay demonstrated linearity over a concentration range of 50 to 5000 ng/ml.
• Extraction efficiency was consistently high, ranging from 97% to 104%.
• Accuracy of the assay was confirmed to be between 98% and 105%.

Conclusions:

• A simplified and effective LC assay for etomidate in beagle plasma has been successfully developed and validated.
• The assay is suitable for accurate and efficient quantitation of etomidate in preclinical research.
• This method provides a robust tool for etomidate analysis in pharmacokinetic studies.
