Abstract
|
|
|
|
The second derivative absorption spectra of acetaminophen in commercial tablet forms were measured without prior separation from other pharmaceutical adjuvants. The second derivative spectra of acetaminophen were found to have no influence on the characteristic absorbance band of it. A plot of 25 sets of the ordinate (Z) values with various acetaminophen concentrations mixed in other additives gave a straight line (correlation coefficient, 0.9999) and the slope was 2.901 X 1O-2Z value/(mcg/ml). The procedures were sufficiently sensitive, precise and economical for the assay of tablets of acetaminophen.
