title: Glycyrrhizin gel as a vehicle for idoxuridine--I. Clinical investigations.
abstract: The therapeutic efficacy of a new formulation that incorporates 0.2% IDU in glycyrrhizin gel has been tested on patients who suffer from herpes of the lips and nose. The preparation was significantly more effective than a commercial 0.5% IDU ointment. It reduced the healing time and produced an almost instantaneous relief from pain. The higher efficacy of the new preparation may be ascribed to the reported anti-inflammatory and antiviral activities of glycyrrhizin together with an enhanced permeation of the IDU through the skin.
