Figure Lengend Snippet: Figure 6. Release curves of naproxen (NAP), free NAP or loaded NAP into the Si1 and Si2 particles, in pH 2.0. Si1- and Si2-5% gave a significantly faster release than Si1- and Si2-20%, respectively, up to 4h. Significantly faster release was seen from the Si1- and Si2-5% 385 formulations, except for Si2-5% at 24h. The 20% formulations did not give significantly different release at most time-points.
