tretinoin) and 13-cis-retinoic acid (better known as isotreti-noin) back in 1946 and 1955, respectively.6,7 Pioneering studies by Stuettgen and Kligman et al., among others in the 1960s, established topical tretinoin as a dermatological treat-ment.8–10 However, further drug development was delayed by Like vitamin A itself, retinoids—retinols are weaker, over-the-counter versions—have both good and bad effects: The oral retinoid acne medication Accutane is often the miraculously effective drug of last resort for severe-acne sufferers, but is known to cause birth defects and liver toxicity. According to RxList, tretinoin irritates the skin and causes rapid skin cell turnover, and actually reduces the number of skin layers 1. Tretinoin, also known as all-trans-retinoic acid (ATRA), is a naturally occurring derivative of vitamin A ().Retinoids such as tretinoin are important regulators of cell reproduction, proliferation, and differentiation and are used to treat acne and photodamaged skin and to manage keratinization disorders such as ichthyosis and keratosis follicularis. Side effects requiring immediate medical attention. Yet side effects, like redness, swelling, peeling, blistering and, erythema, in addition to its high lipophilicity make this challenging. RESULTS This study is based on the hypothesis that topical application of mucosal adhesive film (MAF), as a means to deliver tretinoin, is effective and safe for oral cancer chemoprevention. Topical application of chemopreventive agents is an attractive alternative that reduces toxic effects. Tretinoin 0.025 % Topical Cream Common Brand(S): Retin-A Generic Name(S): tretinoin View Free Coupon METHODS: Risk assessments were conducted on four known human developmental toxicants (valproic acid, methotrexate, thalidomide, and isotretinoin) and a potential developmental toxicant (acetylsalicylic acid). This study evaluated the use of topical 0.05% vitamin A (tretinoin) acid gel for the treatment of oral leukoplakia. Along with its needed effects, tretinoin topical (the active ingredient contained in Retin-A) may cause some unwanted effects. Last Revision: 06/2018 TRETINOIN, USP (Retinoic Acid) Page 5 of 8 Cytotoxic drugs have also been associated with negative health effects for developing fetuses, including higher incidences of spontaneous abortions, congenital malformations, low birth weight, and infertility. Applies to tretinoin topical: topical cream, topical gel/jelly, topical lotion. At doses of 2.5 mg/kg or greater, dam weight gain and food consumption were significantly less than those of control dams. For acne, it is applied to the skin as a cream, gel or ointment. Tretinoin was approved by the Food and Drug Administration as a topical treatment in 1971, but there are some dangers and side effects of using Retin-A 1. Tretinoin (TRT) is a widely used retinoid for the topical treatment of acne, photo-aged skin, psoriasis and skin cancer which makes it a good candidate for topical formulation. In rare cases, when vitamin A intake (from topical retinols and other vitamin A products including supplement pills) exceeds daily recommendations, vitamin A toxicity -- also called hypervitaminosis A -- can result. For leukemia, it is taken by mouth for up to three months. Results: Topical tretinoin: After topical treatment, dams receiving 10 mg/kg daily or greater had severe local and systemic toxicity prompting discontinuation of tretinoin. Tretinoin was applied topically 4 times a day for the management of nonmalignant oral white lesions in 26 patients. Common side effects when used as a cream are limited to the skin and include skin redness, peeling, and sun sensitivity. The clinical response was evaluated in all patients and posttreatment biopsies were performed in ten patients. Tretinoin, also known as all-trans retinoic acid (ATRA), is medication used for the treatment of acne and acute promyelocytic leukemia.
