Densitometric and UV-Spectrophotometric Methods for Simultaneous Determination of Spiramycin adipate in Binary Mixture with Oxytetracycline-HCl or Tetracycline-HCl

Chromatographic analysis of bromhexine and oxytetracycline residues in milk as a drug analysis medium with greenness profile appraisal

“…According to a literature review, several analytical methods for the analysis of OTC alone and in combination with other drugs have been reported. These methods include spectrophotometric methods, [10][11][12][13] TLC, [14][15][16] HPLC [17][18][19][20] and LC-MS-MS. 21,22 Bromhexine has been determined by spectrophotometric methods, [23][24][25] TLC, 26,27 HPLC [28][29][30][31] and LC-MS-MS. 32,33 Aer a comprehensive literature review, only one published HPLC method for the analysis of the two drugs in their available veterinary dosage form was identied. 34 To date, no method has been reported for the analysis of the targeted drugs in milk samples.…”

Utility of a green fluorone-based turn-off fluorescence probe for submicromolar determination and stability testing of two macrolides. Insights into reaction thermodynamics, quenching mechanism, and identification of the oxidative degradation products by ESI+-MS

“…There are also different analytical methods for the determination of these antimicrobials in different matrices. For instance, SPM has been determined by thin layer chromatography (TLC) [5][6][7], liquid chromatography (LC) [8][9][10][11][12][13][14], spectrophotometry [7,15], and voltammetry [16]. As well, LC [11-13, 17,18], spectrophotometry [19], voltammetry [20], and fluorimetry [21] techniques have been applied for the determination of JSM.…”

“…As well, LC [11-13, 17,18], spectrophotometry [19], voltammetry [20], and fluorimetry [21] techniques have been applied for the determination of JSM. Yet, many drawbacks are associated with these methods such as the weak sensitivity of the spectrophotometric [7,15,19], fluorimetric [21], LC [9,10,17],…”

Green versatile micellar electrokinetic chromatographic method for determination of six antimicrobial and anti-inflammatory drugs in combined dosage forms

“…Determination of ORZ was carried out using spectrophotometric [32,33] and HPLC [34,35] methods. The literature for SPI determination includes spectrophotometric [36], HPLC [37,38], UHPLC [39,40] and CE [41] methods. As for TNZ, the recent methods include spectrophotometry [42,43], electrochemical determination [44], TLC [45] and HPLC [46,47].…”
