Tigestol, also known as Tigason, is a brand name for the drug etretinate, which is a synthetic retinoid used in the treatment of severe psoriasis, a chronic skin condition characterized by red, scaly patches. Etretinate works by reducing skin cell production and inflammation, thereby alleviating the symptoms of psoriasis. It is an oral medication that belongs to the family of drugs called retinoids, which are derived from vitamin A. It is important to note that Tigestol is a potent medication and should be used under the supervision of a healthcare professional due to its potential side effects and the need for regular monitoring of liver function and blood lipid levels.
