Description and Uses

Acitretin is the free acid form of etretinate useful in the treatment of severe psoriasis and other disorders of keratinization. Although the two compounds have virtually the same efficacy and teratogenic side-effects, acitretin is advantageous for child-bearing women, as its shorter half-life reduces the necessary contraception period from two years to only one month after treatment ceases.
