To assess the quality of various pharmaceutical formulations and dosage forms, PharmP-FM uses both qualitative and quantitative fingerprinting techniques. The system expands on the SeDeM expert system, which was initially created to evaluate the suitability of powder for direct compression. PharmP-FM creates a graphical representation of the product's pharmaceutical quality using a set of input parameters. The Performance Index (PI), Normalized Parameter Index (NPI), and Formulation Index (FI) are among the system's output parameters. Methods To evaluate PharmP-FM's performance, the paper examines its application in assessing batch-to-batch variability of weight loss supplement capsules and the quality of multisource brand products of levothyroxine tablets. The findings demonstrate PharmP-FM's capability to identify variations in pharmaceutical quality across these products. Results & Conclusion This paper concludes that PharmP-FM exhibits potential promise as a pharmaceutical quality assessment tool. Its user-friendly nature and adaptability to different formulations and dosage forms make it a versatile discriminatory system.
