The 5-Second Trick For sustained release and controlled release formulation slideshare
At pH 2, the amplified permeability in the polyelectrolytes film facilitates the incorporation of DOX Within the PSS/PAH multilayers. Then the adjustment of pH at eight brings about the contraction of the polyelectrolytes as well as the drug molecule results in being trapped inside the polyelectrolyte film. The next washing will clear away any nont
