A gas chromatographic method to measure urinary levels of the central nervous system stimulant fencamfamine and some of its metabolites is described. When 100 mg fencamfamine was given orally to four horses the parent drug could not be detected in the urine. After enzymatic hydrolysis of the urine the major human metabolite, N-desethylated fencamfamine, only accounted for 1% of the dose in 12 h. The major equine metabolites were conjugated parahydroxylated compounds representing 18% of the dose. With regard to horse doping control and analysis, the injudicious use of human doping routine methods for the detection of fencamfamine in equine urine could lead to false negative results.

UI	MeSH Term	Description	Entries
D007202	Indicators and Reagents	Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents.

D002849	Chromatography, Gas	Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.

D000697	Central Nervous System Stimulants	A loosely defined group of drugs that tend to increase behavioral alertness, agitation, or excitation. They work by a variety of mechanisms, but usually not by direct excitation of neurons. The many drugs that have such actions as side effects to their main therapeutic use are not included here.
