title: Spectrophotometric determination of ketotifen in pharmaceutical preparations after isolation on ion-exchanger.
abstract: Spectrophotometric method have been proposed for the determination of ketotifen in complex "Position" (Polfa-Poznań) samples after preliminary separation of excipients. For the determinations of the ketotifen in Pozitan a relative standard deviation of +/-2.0% was found.
