Action/Kinetics: Retinoid binds to and activates all known intracellular retinoid receptor subtypes. Upon activation, the receptors regulate the expression of genes that control cellular differentiation and proliferation in both healthy and cancerous cells. Inhibits growth of Kaposi's sarcoma cells in vitro. Little is absorbed through the skin.
Uses: Treat cutaneous lesions in AIDS-related Kaposi's sarcoma.
Contraindications: Hypersensitivity to retinoids. Use when systemic treatment of Kaposi's sarcoma is needed (i.e., 10 new sarcoma lesions in the prior month, symptomatic lymphedema, symptomatic pulmonary Kaposi's sarcoma, symptomatic visceral involvement). Lactation.
