Use of accelerating solvent extraction for detecting non-steroidal anti-inflammatory drugs in horse feces.

The study examines the technique of Accelerating Solvent Extraction (ASE) to detect the presence of non-steroidal anti-inflammatory drugs (NSAIDs) in horse feces as part of anti-doping measures. The extraction method was tested, optimized, and found to be efficient and time-saving for this purpose.

Introduction to the Research

• The research focused on the application of Accelerating Solvent Extraction (ASE), a method for extracting compounds from solid materials, to detect non-steroidal anti-inflammatory drugs (NSAIDs) in horse feces.
• ASE was used to replace the traditional diethyl ether liquid-liquid extraction method, proving more efficient and time-sensitive.
• The focus of the research was on the detection of substances that may be used for horse doping, hence the need for a reliable method for detecting these drugs in horse feces emerged.

Testing and Optimizing ASE Method

• The ASE technique was optimized to identify several NSAIDs, including meclofenamic acid, flunixin, vedaprofen, celecoxib, carprofen, diclofenac, and ketoprofen.
• The extraction recovery and limit of detection were determined for these drugs using the ASE method.

Application of ASE

• The ASE method was successfully applied to samples of feces collected post drugs administration of meclofenamic acid, flunixin, and phenylbutazone.
• The major metabolites identified in the urine samples of the administered drugs were also detected in the feces, further validating the effectiveness of the ASE method.

Advantages of ASE for Horse Doping Control

• Through the use of ASE, the time required for sample preparation can be significantly reduced. This is important in situations where large-scale analysis is needed, such as in the context of horse doping control.
• The findings suggest that the ASE method can be effectively used on a larger scale for horse doping control.

Application of the Results

• The study’s results could lead to the adoption of the ASE method as a standard procedure in horse doping control.
• The findings also confirm that feces can be used as an effective medium for detecting drugs in horse doping cases, in conjunction with standard urine tests.
