[Drug kinetics in soft contact lenses. I. In vitro studies].

The in vitro kinetics (specifically, absorption and desorption) of drugs belonging to various pharmacological groups (atropine sulfate, gentamicin sulfate, dexamethasone, lecozyme, and poludan) in soft contact lenses (low-hydrophilic with 40% aqueous content and highly hydrophilic with 74% aqueous content. 0.2 and 0.7 mm thick) was studied by radiometry, as were the effects of chemical structure of a drug, hydrophilic properties and thickness of soft contact lenses, and temperature of solution on these processes.
