Analytical Technique for the Determination of Diazepam in Solid Dosage Forms
نویسنده
چکیده
Several methods are available in literature for the determination of percentage purity of diazepam (pharmaceutical raw material) either by non aqueous titration or spectrophotometric methods. For the quantitative determination of diazepam from the commercial pharmaceutical preparations, the current official B.P method (nonaqueous titration and spectrophotometric assay) has been utilized and a comparison has been made between results obtained from both methods. The utilization of spectrophotometric method proved to be a better method for determination of the percentage purity of diazepam pharmaceutical raw material and in the solid dosage form. The spectrophotometric method has been found to be a more rapid, accurate and gives reproducible results.
