Influence of lipophilic counter ions on the transport of ionizable hydrophilic drugs.

R Neubert1, S Fischer.   

Abstract

The influence of lipophilic counter ions on the transport of the hydrophilic drugs pholedrine and bretylium across artificial lipid membranes has been studied using a permeation model system. The transport of both drugs was markedly enhanced by hexylsalicylate and by salts of fatty acids with a maximum at decanoate. The transport of pholedrine was additionally increased by bile salts such as desoxycholate.
