title: [Interactions between macromolecular adjuvants and drugs. Part 17: On the effect of macromolecular adjuvants on the dissolution rate of chlorpromazine from dosage forms (author's transl)].
abstract: The determination of the dissolution rate of chlorpromazine from tablets and triturations containing macromolecular adjuvants by means of a modification of the flow-through type cell according to Langenbucher evidenced a decrease in the dissolution rate produced by polyvinylpyrrolidone, methyl-cellulose and hydroxyethyl-cellulose. It was found that the decrease in the dissolution rate is not due to the confirmed, relatively marked tendency of chlorpromazine to form complexes, but to gel formation.
