We read with interest the article about the determination of bromoureides in biological fluids by High-Pressure-Liquid-Chromatography by Eichelbaum et al. (1978) in this journal. We agree with the authors that measurement of bromide is not relevant for judgion the clinical state of a patient, who is

✦ Synopsis
A sensitive and specific method for the simultaneous determination of bromisoval, carbromal, and methaqualone is described. The drugs are adsorbed from serum onto charcoal at pH 11 and eluted from it with organic solvent. The eluate is separated by high-pressure liquid-chromatography on reverse phase (RP 18) column using acetonitrile: water (26 : 74 by volume) as mobile phase. The eluted drugs are detected by uv-absorption at 210 nm. The method is sensitive, specific, precise, and accurate.

Allantoin is quantitatively determined in biological fluids by reversed-phase high-pressure liquid chromatography. The proteins of blood plasma are precipitated by perchloric acid. Urine can be analyzed directly. The reproducibility was over 99%. The average recovery of added allantoin in blood was
