Figure 6

Time-lapse of wetting induced piroxicam (PRX) crystallization on the fixed surface of the tablet consisting of PRX-loaded hydroxypropyl methylcellulose (HPMC) nanofibers. The PRX release is visualized by scanning white light interferometry (SWLI). Key: (A-I) Initial state of the tablet; (A-II) After wetting with 2 µL of water and evaporating for 1 min; (B) After wetting a second time with 2 µL of water and evaporating for 10 min; (C) After wetting a third time with 2 µL water and evaporating for 10 min. The scale for height differences is changed according to changes in surface altitude (A—0 to 8 μm; C—0 to 90 μm). The diameter and thickness of tablet (disc) are 12.7 mm and 0.8–1.0 mm, respectively. Magnification 30×.
