      J. Planar Chromatogr. 33, 231-244 (2020). HPTLC of apremilast on silica gel with toluene - methanol - ethyl acetate 7:2:1. Quantitative determination by absorbance measurement at 241 nm. The hRF value for apremilast was 63. Linearity was between 200 and 1000 ng/zone. Inter-day and intra-day precision were below 1 % (n=3). The LOD and LOQ were 4 and 13 ng, respectively. Recovery rate was between 99.7 and 100.0 %. Apremilast was subjected to acidic, alkaline, oxidative, dry heat, neutral, and photolytic degradation conditions. The method was implemented using a quality risk management and quality by design approach for regulatory requirements.

      J. AOAC Int. 93, 1180-1191 (2010). TLC of tropisetron and its acid-induced degradation products on silica gel with methanol - glacial acetic acid 22:3 with chamber saturation for 45 min. Detection under UV light at 254 nm. Quantitative determination by scanning at 285 nm. The hRf values were 44, 84, and 92 for tropisetron and degradates I and II, respectively. Linearity was between 1 and 10 µg/zone. Mean accuracy was 100.2 %. The precision was 0.64 %.The limit of detection and quantification for tropisetron was 0.26 and 0.80 µg/zone, respectively. The intraday and interday precisions were evaluated by assaying freshly prepared samples of tropisetron in triplicate concentrations, i. e. 3, 5, and and 9 µg/zone, resulting in 99.8 %, 100.3 %, and 100.4 %, respectively, for interday precision and 99.7 %, 100.2 %, and 99.7 %, respectively, for intraday precision (with a precision of 0.9 %, 0.6 %, 0.8 % and 0.6 %, 0.4 %, 0.6 %, respectively).
