Chlorhexidine kinetics of hydrophilic contact lenses

open access: yesJournal of Pharmacy and Pharmacology, 1978
Abstract An average chlorhexidine concentration of 4·5 μg mg−1 lens (wet weight) was measured in HEMA-based contact lenses after 16 days of the following treatment. The lenses were maintained 16 h daily in 1·5 ml of a solution containing Chlorhexidine digluconate 0·005%, and then worn by adult albino rabbits 8 h daily.
