Simultaneous determination of rifampicin, isoniazid and pyrazinamid by high performance thin layer chromatography

Validation of a rapid micellar electrokinetic capillary chromatographic method for the simultaneous determination of isoniazid and pyridoxine hydrochloride in pharmaceutical formulation

“…There are various analytical procedures for the assay of either ISO or PYR in pharmaceutical preparations and biological fluids, only three methods have been reported to be able to analyze both drugs in combination [3][4][5]. These methods used high-pressure liquid chromatography (HPLC) [3], high performance thin layer chromatography [4] and spectrophotometry [5].…”

“…These methods used high-pressure liquid chromatography (HPLC) [3], high performance thin layer chromatography [4] and spectrophotometry [5]. Several capillary electrophoresis methods for quantitation of ISO [6][7][8][9][10] and PYR [11] have been reported.…”

Determination of isoniazid in human urine using screen-printed carbon electrode modified with poly-l-histidine

“…The importance of INZ has prompted the development of some methods for its determination including chemiluminescence [3], fluorimetry [4], spectrophotometry [5,6], capillary electrophoresis [7] as well as several chromatographic methods [8][9][10]. The electroanalytical methods described in literature for INZ determination in pharmaceutical formulations and human serum have demonstrated success [11][12][13][14][15][16][17][18].…”

Assay of dipyridamole in human serum using cathodic adsorptive square-wave stripping voltammetry

“…Several analytical methods have been used for the determination of dipyridamole in different samples include chromatography [12,13,14,15,16,17,18], spectrophotometry [19,20,21], fluorimetry [22] phosphorimetry [23,24], fluorescence spectrometry [25,26], and voltammetry [27,28,29]. The polarographic method [27] achieved a detection limit sufficient only for tablets assay.…”
