755 Reindel et al. Figure 1. Particle size analysis of the powder obtained after crushing the tablets using (a) Pillcrusher syringe, (b) silent knight pill crusher, and (c) standard mortar/pestle. Table 2. Mean Particle Size of Powders Obtained From Different Tablet Crushing Methods. Sample Pillcrusher Syringe Silent Knight pill crusher Standard mortar/pestle Mean size, μm SD, μm 389.6 412.5 68.2 149.5 81.6 2.4 with increasing ratio of water. Based on these observations, eslicarbazepine acetate suspension (40 mg/mL) prepared using ORA-Plus:water ratio of 50:50 v/v was found to be optimal for delivery through the enteric tubes. The physical stability of the prepared suspensions was assessed by storing the suspensions in glass vials and visually observing the settling behavior (particle sedimentation)
