Abstract
The nitromethane-Hyamine method for assay of nitrofurantoin in whole blood has been improved: smaller volumes of blood (0.8 ml) are required, the sensitivity is greater (0.2 pg/mI), and the solution to be read is more stable than in the original method. The analysis detects 70 to 72% of 1 to 4 Ag of nitrofurantoin added per milliliter of whole blood. Blood concen-trations after the usual therapeutic peroral dose (100 mg) of nitrofurantoin are reported.Keywords
