Abstrakt: A new, simple hight performance thin layer chromatography (HPTLC)-Spectrodensitometric strategy was created and approved for the synchronous estimation of four antibacterial specialists: ceftazidime (CEF), tazobactam (TAZ), tobramycin (TOB) and sulbactam (SUL). The four compounds were separated on TLC aluminum plates covered with silica gel 60 F254, using chloroform–acetonitrile–methanol–ammonia (4:1:0.5:0.15, v/v/v/v) as a mobile phase at 254 nm. Linear correlation was obeyed over the concentration ranges of 12.0–72.0, 2.0–12.0, 3.0–18.0 and 10.0–50.0 μg mL−1 for CEF, TAZ, TOB and SUL, respectively. The proposed approach is efficient, repeatable and convenient as a flexible method for the quality control of diverse combinations of these pharmaceuticals in various pharmaceutical preparations, with high percent recoveries that are highly consistent with labeled data. When the findings of the proposed technique were compared to those of the comparison methods, there were no critical contrasts in terms of precision and accuracy. [ABSTRACT FROM AUTHOR]
