| Abstract: |
The ternary mixture of doxycycline hyclate (DOX), ambroxol hydrochloride (AMB), and ambroxol synthetic precursor and process impurity (IMP) as chemically identified in the British Pharmacopeia as 2-amino-3, 5-dibromobenzaldehyde was examined for the first time using an ultra-performance liquid chromatographic technique. The presented work aimed to develop and validate a green accurate sensitive modern method for determination of this mixture. The obtained UPLC was accomplished by using an UPLC C18 column with mobile phase combination of acetonitrile: water (60:40, v/v) which was flowed at the rate of 0.22 mL per minute. Elution was in an isocratic manner and temperature control set at room temperature. UV was used to identify the effluent, which was injected at a volume of 5.00 µL; 370 nm for DOX and 240 nm for AMB and IMP. In concentration ranges; of (5–150) µg mL−1, linearity of both DOX and AMB was attained and of (0.5–40) µg mL−1, linearity of IMP was attained. Accuracy of this UPLC method was found to be 100.28, 99.66, and 100.36 for DOX, AMB, and IMP, respectively. ICH standards were followed while making the method validation. The existing combined pharmaceutical dosage form was analyzed by the obtained UPLC method for determination of the evaluated drugs successfully and the obtained results expressed as (Recovery % ± SD) were 101.02 ± 1.37 for DOX and 102.22 ± 1.56 for AMB. Also, the statistically significant correlation of our created approach to the reported HPLC method revealed no appreciable differences in terms of accuracy and precision. The developed method's greenness profile was appraised using many greenness metrics, green assessment comparison between the established columnar method and the published ones was made.
