Recent Development and Validation of Bisacodyl Analysis Method in Tablet with Absorbance Method and Area under Curves Method in Ultraviolet Spectrophotometry | Chapter 7 | Technological Innovation in Pharmaceutical Research Vol. 3

A precise, reliable, rapid, and inexpensive simple approach for the analysis of bisacodyl tablets has been devised and validated using UV spectrophotometry with absorbance technique and area under the curve. This process is carried out in a 0.1 N hydrochloric acid solvent at a maximal absorption wavelength of 263.60 nm and a region under the curve of 244.40 - 297.60 nm. The analytic procedure is validated using linearity, identification limits, quantification limits, precision, and accuracy. The regression equation y=0.02156x + 0.09258 (r=0.99963) shows the linearity of the absorbance method under the curve, while the regression equation y=0.30618x + 1.17400 (r=0.99787) shows the linearity of the broad area method. The detection and quantification limits for the absorbance method are 1.411099 and 4.276059, respectively, while the detection and quantification limits for the region under the curve method are 1.968774 and 5.9659197, respectively. The absorbance approach's region under the curve and accuracy also meet the validation standards of 80-120 percent. The absorbance method's region under the curve and precision satisfied the established criteria. criteria with an RSD of less than 2%. To conduct statistical analysis, the paired sample t test was utilized, and the findings revealed that the two The approaches were not that dissimilar. Bisacodyl can be measured using both the absorbance method and the small area method. The curves indicate the results of the analysis.

Recent Study on Development and Validation of Loperamide Hydrochloride Tablet Analysis Method with Absorbance and Area under Curve Methods Spectrophotometrically | Chapter 6 | Technological Innovation in Pharmaceutical Research Vol. 3

 The absorbance method and the area under the curve method were used to develop and validate the loperamide hydrochloride tablet method of analysis. The optimum solvent in this study was 0.1 N methanol and hydrochloric acid (9:1), with maximum absorption at wavelength 259.00 nm.

The linearity of loperamide hydrochloride was determined in the concentration range 200-600 ppm using the absorbance method and the areas under the curve method, with correlation coefficient values of 0.9998 and 0.9865, respectively. The findings revealed that loperamide hydrochloride levels in The absorbance method and the area under the curve method yielded 105.71 percent and 96.20 percent generic pills, respectively. The findings of the absorbance method and the area under the curve method for determining loperamide levels in trademark pills were 102.85 percent and 98.57 percent, respectively. Both samples met the requirements of Pharmacopoeia Indonesia edition V, which are 90% to 110 percent. The absorbance method for the analysis of loperamide hydrochloride in tablets is legitimate, however the area under the curve technique is unsuitable for the analysis of loperamide hydrochloride in tablets.
