| Abstract | ||
| Content uniformity (CU) is a critical quality attribute in tablet manufacturing process. The active pharmaceutical ingredient (API) is usually determined off-line techniques such as, high performance liquid chromatography (HPLC) which is a slow, destructive technique and requires sample preparation. Therefore, Near Infrared (NIR) spectroscopy was employed as a process analytical technology (PAT) tool to determine the API and consequently the content uniformity of tablets. NIR spectroscopy is a fast, non-destructive technique and requires minimal sample preparation. The purpose of this work was to develop and validate NIR reflectance method for the determination of the ibuprofen content (mg) for the content uniformity for ibuprofen tablet. Partial least squares (PLS) model for the NIR reflectance was constructed by using calibration laboratory tablets with different ibuprofen (IBU) contentsspanning from 146.47 mg to 243.91 mg. The predictive performance of the proposed method was evaluated by traditional chemometric criteria. The corresponding values for the root mean square error of prediction (RMSEP) were equal to 0.96% for NIR reflectance method. Besides, the proposed NIR method was successfully validated and implemented for the determination of the content uniformity for three batches that represent three levels of IBU content (160 mg, 200 mg and 240 mg). | ||
