Abstract:
A spectrophotometric method is described for the determination of tilidine in its dosage forms (injection, drops, suppositories). The method is based on ion-pair extraction with chloroform at pH 3.5 using bromocresol green or bromophenol blue as the ion-pairing reagents. The spectrophotometric measurements are carried out at the absorption maxima at 415 and 411 nm, respectively.
