Tretinoin is a valuable medication in treating mild, moderate, and severe acne that can be used topically or systemically. Tretinoin is also used systemically in the management of acute promyelocytic leukemia APL. Tretinoin is a vitamin A derivate in the retinoids class of medications. This activity outlines and reviews the indications, actions, and contraindications of tretinoin as a valuable agent in treating acne vulgaris and APL management and therapy.
This activity will highlight the mechanism of action, adverse event profile, and other key factors such as off-label uses, including some indications of APL, pre-malignant and malignant skin conditions, and other common skin conditions such as psoriasis, dosing of both oral and topical treatment options, monitoring of both topical and oral tretinoin use i. Objectives: Explain the importance of monitoring for patients on tretinoin therapy, including target triglyceride and liver function concentrations.
Summarize the risks associated with initiating tretinoin treatment along with key patient counseling points. Identify the most common adverse events associated with tretinoin treatment.
Outline the importance of how collaboration and coordination among the interprofessional team can enhance patient care when dosing and monitoring tretinoin to improve patient outcomes for patients receiving topical anti-acne and palliative for photoaging and oral antineoplastic tretinoin.
Access free multiple choice questions on this topic. Tretinoin is a generic name for a medication derivative of vitamin A retinol , also commonly known as all-trans retinoic acid ATRA.
Tretinoin can be given systemically or topically for various indications. The exact mechanism by which topical tretinoin functions are not completely understood, but current evidence suggests mediation through binding of retinoic acid receptors RARs alpha, beta, and gamma along with retinoid X receptors RXRs by blocking inflammatory mediators.
By doing this, the production of procollagen increases to augment collagen type I and III formations. RAR-gamma effects are associated with mucocutaneous tissues and bone.
Tretinoin's effectiveness as an acne medication is because of its ability to modify the abnormal follicular formation that comes from excessive keratinization of epithelial cells. Tretinoin promotes cornified cell detachment and enhances shedding. Tretinoin increases mitotic activity, thereby increasing loosely-adherent corneocytes turnover. By doing so, the comedo contents can be expelled, with a reduction of microcomedo precursor lesion of acne vulgaris.
RAR-alpha and -beta has presented in associated with APL and squamous cell malignancies, respectively. Retinoic acid binds to retinoic acid receptor alpha, a member of the steroid-thyroid hormone receptor superfamily.
Again, like topical tretinoin, the exact mechanism of systemic tretinoin is unclear but is hypothesized to include the following:. Systemic tretinoin produces complete remission by inducing an initial primitive promyelocyte maturation followed by bone marrow and peripheral blood repopulation occurring by normal, polyclonal hematopoietic cells. For the treatment of APL, the administration is typical with a meal; capsules are not to be opened or crushed.
According to the FDA drug labeled guidelines of orally administered tretinoin, most patients will experience drug-related toxicity, such as headaches, weakness, fever, and fatigue.
Interruption of therapy is rarely required as these adverse effects are rarely permanent or irreversible. According to FDA labeled drug guidelines, contraindications include patients with evidence of hypersensitivity to tretinoin or any of its components.
If administered during pregnancy, there is a significantly high risk of fetal loss and malformations, including the musculoskeletal system, thymus, central nervous system, external ear, eye, great vessel abnormalities, a cleft palate, facial dysmorphia, and parathyroid hormone deficiency.
In all females undergoing tretinoin therapy, effective contraception must be used throughout treatment then continued for one month following discontinuation. Even if the patient has a history of infertility or menopause, contraception must be used, the patient has undergone a hysterectomy. Two 2 reliable forms of contraception are the recommendation to be used simultaneously, even in patients who have a history of infertility or menopause.
Abstinence may also be a chosen method of contraception. Patients who have undergone hysterectomy do not need a form of contraception.
Discussion of continuing or terminating the pregnancy should occur between patient and physician if there is contraception during treatment. In patients who lack genetic markers t 15;17 translocation, alternative treatment options should be considered.
Oral tretinoin is also contraindicated during breastfeeding, pregnancy during the first trimester caution if pregnancy in the second or third trimester , caution in females of reproductive potential, caution in pediatric patients. Patients with acute promyelocytic leukemia APL should be under strict supervision by an APL experienced physician, facility as well as supportive services to monitor drug tolerance and toxicity properly as there can be severe adverse reactions to taking oral tretinoin.
Monitor for hypersensitivity, photosensitivity, and any other skin irritation or allergies. Monitor APL for side effects including major, life-threatening side effects such as retinoic acid RA-APL syndrome and leukocytosis and response to treatment. Monthly follow-ups visits are required. Fasting lipid checks are recommended weekly or biweekly to monitor lipid response, but this is relative to the individual's health. Asymptomatic, young patients without a personal or significant family history of dyslipidemia or diabetes mellitus require less frequent laboratory draws mentioned above.
Clinical assessment of the following areas is necessary to assess for treatment response and adverse effects:. Monthly follow-up visits are typical to fulfill the requirements of the iPLEDGE program a program to eliminate fetal exposure to isotretinoin.
Due to tretinoin teratogenicity, women of childbearing potential are recommended the use two dependable forms of contraception while on oral tretinoin therapy for APL and one month following discontinuation of treatment; monitoring for pregnancy and contraception counseling repeated monthly while on medication. Delay of treatment should occur until obtaining a negative pregnancy result.
If treatment cannot be delayed in the case of APL treatment , the patient should use two forms of contraception. Symptoms of overdose with topical tretinoin use may include excessive redness, peeling, and discomfort.
Symptoms of overdose with oral tretinoin include the following: cracked and sore lips, redness, headache, flushing, stomach pain, dizziness, loss of coordination. Case Report: year-old overdosed on mg of ingested tretinoin in a suicide attempt and developed nothing besides some non-bloody diarrhea, which received treatment with hydration and activated charcoal.
If liver enzymes increase to more than three times over baseline, the recommendation is to discontinue isotretinoin. ATRA initiation should be immediate once APL is suspected, especially if the diagnosis supports genetic or molecular data. If molecular or genetic data do not support the diagnosis, then ATRA should no longer be given. Before tretinoin prescription and eventual use, pregnancy status should be negative through a urine pregnancy test before eventual prescribing and use of tretinoin; this is due to the routine use of urine pregnancy tests, complications such as fetal malformations, and risk of fetal loss.
It is still unknown as to whether oral tretinoin appears in breast milk, but because of potentially serious adverse effects that may take place in breastfed infants, breastfeeding should be strongly discouraged. Swift identification of RA-APL syndrome, an unpredictable but frequent complication, includes symptoms such as dyspnea, fever, weight gain, pleural and pericardial effusions, acute respiratory distress, pulmonary infiltrates on chest x-ray, edema, and multi-organ failure.
After resolved, treatment may continue. Sunscreen is a requirement for all patients on tretinoins, as there is an increased risk of photosensitivity. Encourage avoidance of exposure to sunlight or tanning beds. Patients should be encouraged to wear protective clothing and use sunscreen recommended SPF 15 or higher according to the tretinoin drug label when they are outdoors, even on a cloudy day. Advise patients to avoid using skin products that may cause skin irritation and dryness, such as harsh soaps, shampoos, hair coloring chemicals, hair removers, or skin products that contain alcohol, spices, astringents, or lime.

ATRA must be used in combination with other medications i. Nursing mothers should discontinue nursing before starting oral tretinoin, as nursing infants have potentially serious adverse effects. Patients should take a missed dose as soon as possible unless it is time for the next dose, at which point it's recommended to skip the missed dose and proceed with the regular schedule of medication; patients should not take a doubled dose.

Drug information provided by: IBM Micromedex. Tretinoin is used to treat acne or other skin diseases as determined by your doctor. It works partly by keeping skin pores clear. One of the tretinoin creams is used to treat fine wrinkles, dark spots, or rough skin on the face caused by the damaging rays of the sun.
