title: [Comparative in vitro studies of allopurinol in commercial preparations].
abstract: Controls of content uniformity, disintegration and dissolution (in three different methods) were made in 5 commercial samples of allopurinol tablets. Two of the examined "normal tablets" were not acceptable. Our tests also resulted that U.S.P. XX "basket" dissolution method gives lower values of drug release than the two other methods (paddle).
