| Summary: | Development and validation of a liquid chromatography - tandem mass spectrometry (LC-MS/MS) method for the determination of adapalene in
pharmaceutical forms for skin application were presented. The MS/MS analysis
of adapalene was performed by use of three mobile phases, consisted of
acetonitrile and (a) 0.1 % formic acid, (b) 0.1 % trifluoroacetic acid and
(c) 20 mM ammonium acetate. The strongest signals of parent ion and dominant
product ion were obtained in negative mode by use of the mobile phase (c).
Validation of this method was performed according to the ICH guidelines.
Small variations of selected chromatographic parameters (concentration of
ammonium acetate, mobile phase composition, column temperature and flow rate)
did not affect qualitative and quantitative system responses significantly,
which proved method’s robustness. The method is specific for the
determination of adapalene. Linearity was proved in the concentration range
6.7 - 700.0 ng mL-1 (r = 0.9990), with limits of detection and quantification
2.0 ng mL-1 and 6.7 ng mL-1, respectively. Accuracy was confirmed by
calculated recoveries (98.4 % - 101.5 %). Precision was tested at three
levels: injection repeatability, analysis repeatability and intermediate
precision. Calculated relative standard deviations were less than 1, 2 and 3
%, respectively. [Projekat Ministartsva nauke Republike Srbije, br. OI172041
