J. Chromatogr. Sci. 54 (1), 36-42 (2016). Description of a method for simultaneous determination of cinnarizine (CIN) and dimenhydrinate (DIM) by TLC on silica gel with ethyl acetate – methylene chloride 4:1, detection and quantification by densitometry at 254 nm. Linearity was in the range of 0.5-6 µg/band for CIN and 1-6 µg/band for DIM. The mean recovery was 100 % for both substances. The methods were applied to the simultaneous determination of CIN and DIM in bulk powder, laboratory-prepared mixtures and pharmaceutical dosage forms.
