Perform Homogeneity Checks on Semisolids Before Stability Storage
Understanding the Tip: Why homogeneity matters in semisolid stability testing: Semisolid dosage forms like creams, ointments, gels, and pastes are inherently heterogeneous due to their semi-fluid matrices. Active pharmaceutical ingredients (APIs) or excipients may settle, migrate, or distribute unevenly during manufacturing, filling, or early storage. Placing a non-homogeneous sample into stability studies can lead to…
