Deposition Dosages of Three Cromolyn Forms by Cascade Impactor

Figure 3

Results of analysis using a cascade impactor. Particle size distribution and cumulative values in 4 dosage forms: (a) Intal capsule (DP), (b) Intal MDI, (c) one solution inhalant (a mesh-type nebulizer NE-U22), and (d) the other solution inhalant (a jet-type nebulizer NE-C28) are shown in blue and pink, respectively. The data points represent the means of three independent experiments.
