Panrexin is chemically related to Vitamin A and is a yellowish powder with a molecular formula of C20H28O2 and a molecular weight of 300.44.

Panretin, the gel version, should be applied two times a day to cutaneous KS lesions during the initial stages of treatment. Apply the gel liberally to cover the lesion with a generous coating, and then allow it to dry for three to five minutes before covering it with clothing. Avoid applying the gel on or near mucosal surfaces (nose, mouth, and eyes) of your body.
