A novel analytical methodology was developed for simultaneous high-performance liquid chromatographic quantitation of antipyrine and lorazepam in biological fluids using phenacetin and flunitrazepam as internal standards, respectively. A gradient solvent system was used to achieve specificity and sensitivity for each of the compounds in biological fluids… CONTINUE READING
