Polarographic behaviour of Aceclofenac, Tenoxicam and Droxicam in a methanol–water mixture

Validation of a tubular bismuth film amperometric detector

“…Consistent with results obtained for DS and similar non-steroidal drugs when using mercury electrodes [33], a linear shift of the peak potential towards more negative values was observed as the pH increased from 2.0 to 4.0 (Fig. 3(B)).…”

Spectrofluorimetric Method for Determination of Some Oxicams Using Potassium Bromate

“…Several analytical methods were developed for their assay in pharmaceutical formulations and biological fluids including: non aqueous titration 1 spectrophotometric [2][3][4][5][6][7][8][9][10][11][12][13] , flow injection analysis [14][15][16] , electrophoresis 17&18 , electrochemical 6,[19][20][21][22][23][24][25] , GLC 26 , HPTLC [27][28][29][30] and liquid chromatography 4, . On the other hand, spectrofluorimetric determination of Px and Tx in HNO 3 was studied [63][64] Also effect of βcyclodextrin on the fluorescence of Px was investigated 65 .…”

<b>Indirect spectrophotometric determination of piroxicam and tenoxicam through oxidation with potassium permanganate</b>

“…The pharmacological actions of these oxicams are related to inhibition of cyclooxygenase (Cox), a key enzyme of prostaglandine biosynthesis at the site of inflammation [1]. Several methods have been reported for determination of piroxicam and tenoxicam including spectrophotometry for PX [2][3][4][5][6][7][8][9][10] and for TX [11][12][13][14], chromatography, electroanalytical and physicochemical methods for PX [15][16][17][18][19][20] and for TX [21][22][23]. Among the various methods available for the determination of drugs, spectrophotometry continues to be very popular, because of its simplicity, specificity and low cost.…”
