The raw material is acknowledged to be a source of variability, however, the conventional, empirical development approach does not offer much information regarding its critical attributes and how processes can be modulated to remain in the constant quality region of the product. The study aimed to develop extended release hydrophilic matrix tablets with indapamide based on the Quality by Design (QbD) concept, evaluating the impact of interchanging different types and suppliers of raw material on the finished product quality profile. Results showed significant in vitro release test variability, with 16 - 71% failure rates when compared to four different EMA and FDA dissolution specification recommendations. Design of experiments based impact assessment concluded that the active pharmaceutical ingredient, hydroxypropyl methylcellulose and compression force was accountable for the variation, while orthogonal partial least squares (O2PLS) based root cause analysis extension redefined results in term of critical material attributes. Findings suggest that a risk-based, multivariate analysis assisted control strategy for the incoming raw materials could prevent quality concerns within routine manufacturing.
