This paper reports the use of Near Infrared (NIR) spectroscopy as a Process
Analytical Technology (PAT) tool for monitoring the metformin hydrochloride
and polyvinilpyrolidone (PVP) mixing process, which is the first stage in the
tablet production. Blend homogeneity was tested using the noninvasive NIR
spectroscopy method and Partial Least Squares (PLS) regression model was
applied for the analysis of the obtained spectra. Simultaneously, the
critical parameter (metformin hydrochloride content) was monitored by
classical analytical technique, validated HPLC method, commonly used for this
purpose. Based on the high sensitivity of the model developed in this study,
as well as the established correlation among the results obtained by
different methods, it can be concluded that the proposed rapid and
noninvasive technique can be an effective tool for one of the critical
manufacturing step monitoring in solid dosage forms production.
