Tretinoin

Tretinoin, also known as all-trans-retinoic acid (ATRA), is a naturally occurring derivative of vitamin A (retinol). It is an oxidation product in the physiological pathway of vitamin A metabolism. In human circulation, tretinoin is normally found at very low concentrations, approximately 4 to 14 nmol/L. Tretinoin exhibits anti-inflammatory, antineoplastic, antioxidant, and free radical-scavenging activities. It has been used in dermatology for many years to treat various skin conditions ranging from acne to wrinkles and activates nuclear receptors to regulate epithelial cell growth and differentiation. Tretinoin is given orally to treat acute promyelocytic leukemia and topically to treat skin conditions such as acne.

Oral tretinoin is indicated for induction of remission in adults and pediatric patients one year of age and older with acute promyelocytic leukemia (APL), characterized by the presence of t(15;17) translocation or presence of PML/RARα gene expression and who are refractory to or who have relapsed from anthracycline chemotherapy or for whom anthracycline-based chemotherapy is contraindicated. Topical tretinoin is also indicated alone or in combination with benzoyl peroxide or clindamycin for the treatment of acne vulgaris. It is also used in prescription and over-the-counter for treating various skin conditions such as melasma, hyperpigmentation, and photoaging alone or in combination with other drugs.
