Abstract
Regarding the preparation of a local drug delivery system, the possibility of incorporating an active substance in a matrix system was investigated to prolong the drug release. A complex between sodium alginate and a triple copolymer of dimethyl aminoethyl methacrylate was prepared in the presence of a cross-linking agent- malic acid. The formation of a polyelectrolyte complex was proven by turbidimetry, determining the specific viscosity of the diluted solutions of sodium alginate, EE 100, malic acid with IR spectroscopy.
