title: Modified NF method for quantitative determination of pentaerythritol tetranitrate.
abstract: A modified NF method for the quantitative determination of pentaerythritol tetranitrate is reported. A solution of powder is made directly from the dosage form in glacial acetic acid and is then reacted with phenoldisulfonic acid TS. The proposed method saves approximately 75% of the time required with the NF method. The results on six differnet commercial dosage forms with four different colors and three other active ingredients are reported.
