RESULTS AND DISCUSSION
The microcapsules loading of naproxen was theoretically calcu-
lated and the intended value was 22.2%. The naproxen content of the
microcapsules varied from 14.8% to 15.3 % for microcapsules containing
polymer. However, when the microcapsules included plasticizers the
naproxen content was between 15.9% and 16.8%, as it can be seen in
Table 2.
