Increase in water permeability of negatively charged liposomal membrane by local anesthetics.

Abstract

Effect of the local anesthetics dibucaine, tetracaine, lidocaine and procaine on the water permeability of phospholipid membrane was examined using liposomes composed of bovine heart cardiolipin and egg yolk phosphatidylcholine in a molar ratio of 2/98 by monitoring the osmotic shrinkage of liposomes in hypertonic glucose solution at pH 7.3 and 30 degrees C… (More)
