Abstract The properties of complexes of richlocain, a new local anesthetic drug, with linear and weakly crosslinked poly‐N‐vinylpyrrolidone were investigated with changes in media properties of pH, temperature, and solvent thermodynamic quality. The kinetics and activation energy of drug release from the gel matrix were determined. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 89: 2977–2981, 2003
