Figure 6 (A, B, C):

All images are shown at 2x magnification. (A) Freshly formulated 5% drug loading dexamethasone oleogel showing presence of particles (blue arrow) (B) Gel in (A) after 4 months drug release. Particles are no longer visible, but have been replaced by small circular voids that are smaller in size and more uniformity in shape. The red arrow points to one of the many voids located throughout the gel. (C) Gel in (B) after melting and solidification. Voids are no longer visible because the oil phase filled the spaces during the melting process.
