Objective To develop near-infrared spectroscopy (NIRS) uniformity models for sampling of Pravastatin Sodium Tablets from overall manufactures in Chinese market, to evaluate the uniformity of Pravastatin Sodium Tablets and their active pharmaceutical ingredients, and provide robust, accurate, and representative uniformity models. Methods NIRS models for 65 batches of tablets were built for four individual manufactures from five manufactures. The active pharmaceutical ingredients form the four manufactures and an amorphous powder were investigated by comparing NIR spectrum. Results Uniformity Models for the four different manufactures were built with prediction rate 100%, respectively. The spectra of four active pharmaceutical ingredients and an amorphous powder showed differences in various crystallographic forms of NIRS. Conclusion It demonstrates the potential of NIRS being a rapid and highly effective method for the identification of Pravastatin Sodium Tablats, the investigation of their preparation process, and the discrimination of the active pharmaceutical ingredients from their various crystallographic forms.
