Liquid chromatographic determination of identity, content, and content uniformity of desipramine, fluphenazine, and promazine.
A liquid chromatographic procedure has been developed for the assay, content uniformity, and identification of single active ingredient formulations of desipramine, fluphenazine, and promazine. The drugs are extracted from formulations with methanol or dilute hydrochloric acid and quantitated against an internal standard (norephedrine). The drugs are identified by comparison of retention times with those of the reference standards.
