How Alitretinoin Works:
Retinoids are drugs that are relatives of vitamin A. Retinoids control normal cell growth, cell differentiation (the normal process of making cells different from each other), and cell death during embryonic development and in certain tissues later in life. Retinoids effects on the cells are controlled by receptors on the nucleus of each cell (nuclear receptors).
There are two major classes of retinoid nuclear receptors: retinoic acid receptors (RAR) and retinoid-X-receptors (RXR). There are also subtypes within each class. Each of these types of receptors has different functions in different tissues. The different retinoid drugs work by binding to different receptors, which, in turn, affect cell growth and differentiation.
Retinoids are relatively new types of anti-cancer drugs. They have been used alone or in combination to treat a variety of cancers such as skin cancers, cutaneous T-cell lymphoma, acute promyelocytic leukemia, lung cancer, breast cancer, ovarian cancer, bladder cancer, kidney cancer, and head and neck cancers. Retinoids have also been used experimentally in an attempt to prevent certain types of cancer. There is ongoing research to determine their role in both cancer treatment and prevention.
Retinoids have been associated with side effects such as skin problems (dryness, peeling, itching, sun sensitivity), reversible elevation in liver enzymes, temporary abnormal lipid levels, low thyroid levels (hypothyroidism), and headaches. Taking supplemental doses of vitamin A may increase these side effects. Vitamin supplementation should be discussed with your physician.
