Abstract We aim in this work to develop new chromatographic and spectrophotometric methods for rapid simultaneous separation and determination of selected drugs in bulk and dosage forms. This point of research is concerned with different techniques such as spectrophotometric and HPLC methods for quantitative determination of some pharmaceutical compounds containing amine as cephalosporins and thiol groups as captopril in bulk and dosage forms. Trials are carried out to develop new methods for determination of these drugs. The different parameters are studied in details to optimize the proposed methods and statistical analysis has been done to compare the proposed methods with the reported refrence methods. |
