Excipient information presented when available (limited, particularly for generics); consult specific product labeling.
Soriatane: 10 mg, 17.5 mg, 25 mg [contains edetate calcium disodium]
Generic: 10 mg, 17.5 mg, 25 mg
Brand Names: U.S.
- Retinoid-Like Compound
Binds to and activates all nuclear subtypes (alpha, beta, and gamma) of retinoid X receptors (RXR) and retinoic acid receptors (RAR) to inhibit the expression of the proinflammatory cytokines interleukin-6 (IL-6), migration inhibitory factor-related protein-8 (MRP-8), and interferon-gamma (markers of hyperproliferation and abnormal keratinocyte differentiation). Resulting actions are anti-inflammatory and antiproliferative, and keratinocyte differentiation is normalized in the epithelium.
Oral: ~72% absorbed when given with food
Metabolized to cis-acitretin; both compounds are further metabolized. Concomitant ethanol use leads to the formation of etretinate (active).
Feces (34% to 54%); urine (16% to 53%)
Onset of Action
May take 2 to 3 months for full effect; improvement may be seen within 8 weeks
Time to Peak
Acitretin: 49 hours (range: 33 to 96); cis-acitretin: 63 hours (range: 28 to 157); etretinate: 120 days (range: Up to 168 days)
>99% bound, primarily to albumin

Concerns related to adverse effects:
• Capillary leak syndrome: Capillary leak syndrome, a potential manifestation of retinoic acid syndrome (differentiation syndrome) has been reported with acitretin use. Capillary leak syndrome features may include localized or generalized edema with secondary weight gain, fever, and hypotension; rhabdomyolysis and myalgias have also been reported. Laboratory tests may show neutrophilia, hypoalbuminemia, and an elevated hematocrit. Discontinue use if capillary leak syndrome develops during therapy.
• Depression: Depression, including aggressive behavior and thoughts of self-harm have been reported; use with caution in patients with a history of mental illness.
• Exfoliative dermatitis: Exfoliative dermatitis has been reported with acitretin use; discontinue use if exfoliative dermatitis occurs during therapy.
• Hepatotoxicity: [US Boxed Warnings]: Hepatitis has been reported (including fatalities); some patients received etretinate for ≤1 month before presenting with hepatic signs or symptoms. Changes in transaminases have occurred in up to 1/3 of patients, which generally returned to normal after discontinuation of treatment. Monitor for hepatotoxicity; discontinue if hepatotoxicity is suspected.
• Lipid effects: Lipid changes, including increased triglycerides, increased cholesterol, and decreased HDL, are common (up to 66%), which were reversible upon discontinuation of treatment; increased triglycerides may lead to pancreatitis. Fatal fulminant pancreatitis has been reported. Use with caution in patients at risk of hypertriglyceridemia (eg, patients with lipid metabolism disturbances, diabetes mellitus, obesity, increased alcohol intake, or a familial history of these conditions). Consider discontinuation if hypertriglyceridemia and decreased HDL persist. Use is contraindicated in patients with chronic abnormally elevated blood lipid values.
• Otic effects: Tinnitus and impaired hearing have been reported with use; consider therapy discontinuation and further evaluation if clinically indicated.
• Photosensitivity: May be photosensitizing; minimize sun or other UV exposure to treated areas. The risk of burning is increased with phototherapy; decreased doses are required.
• Pseudotumor cerebri: Retinoids, including acitretin, have been associated with pseudotumor cerebri (benign intracranial hypertension). Concurrent use of other drugs associated with this effect (eg, tetracyclines) may increase risk. Early signs and symptoms include papilledema, headache, nausea, vomiting, and visual disturbances. Discontinue use in patients experiencing papilledema.
• Skeletal abnormalities: Patients receiving long-term treatment should be periodically examined for bony abnormalities; risk vs benefit of therapy should be considered if abnormalities occur.
• Visual disturbances: May cause adverse effects to the eyes and vision, including a decrease in night vision or decreased tolerance to contact lenses. Use caution when operating vehicles at night; discontinue if visual changes occur.
• Diabetes: Impaired glucose control has been reported with retinoid use. Use with caution in patients with diabetes mellitus; new cases of diabetes have been diagnosed.
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
• Ethanol use: [US Boxed Warning]: Female patients should abstain from ethanol or ethanol-containing products during therapy and for 2 months after discontinuation.
• Females: [US Boxed Warning]: Females of childbearing potential must be able to fulfill all conditions for use prior to initiating therapy, including a Patient Agreement/Informed Consent (consult manufacturer's labeling for further detail). Prescriptions should be written for a monthly supply. The Do Your P.A.R.T. (Pregnancy Prevention Actively Required During and After Treatment) program explains teratogenic risks and requirements expected of females of childbearing potential to prevent pregnancies from occurring during use and 3 years following discontinuation; this should be used to educate patients and healthcare providers. Information for the Do Your P.A.R.T. program is available at www.soriatane.com/doyour-part-Program.html or by calling 1-888-784-3335.
• Pediatric: Growth potential may be affected. Long-term use of high-dose oral retinoids within this population has been associated with decreased bone mineral density, skeletal hyperostosis, and ossification of interosseous tendons and ligaments of the extremities (Menter, 2009).
• Pregnancy: [US Boxed Warning]: Acitretin is a known teratogen and contraindicated in females who are or may become pregnant. Birth defects (including facial, ear, central nervous system, cardiovascular, limb, bone, and joint) have been noted following acitretin exposure during pregnancy. Use only in women with severe psoriasis that is unresponsive to other therapies or with contraindications to the use of alternative treatments. Pregnancy must be avoided for at least 3 years after treatment discontinuation. Two reliable forms of contraception must be used simultaneously for 1 month prior to initiating therapy, during therapy, and for 3 years after discontinuation. Two negative pregnancy tests (sensitivity at least 25 milliunits/mL) are required prior to initiating therapy; pregnancy tests must be repeated every month during treatment. In addition, because ethanol forms a teratogenic metabolite and would increase the duration of teratogenic potential, ethanol should not be consumed during treatment or for 2 months after discontinuation. Any pregnancy which occurs during treatment, or within 3 years after treatment is discontinued, should be reported to the manufacturer at 1-888-784-3335 or to the FDA at 1-800-FDA-1088.
• Hazardous agent: Use appropriate precautions for handling and disposal (NIOSH 2014 [group 3]).
• Blood donation: [US Boxed Warning]: All patients should be advised not to donate blood during therapy or for 3 years following completion of therapy.
• Experienced physician: [US Boxed Warning]: Only physicians experienced with the diagnosis and treatment of severe psoriasis, including the use of retinoid treatment, and physicians who understand the risk of teratogenicity should prescribe acitretin.
• Medication guide: [US Boxed Warning]: All patients must be provided with a medication guide each time acitretin is dispensed. Female patients must also sign an informed consent prior to therapy.
• Subsequent use: Most patients experience relapse of psoriasis after discontinuing therapy. Subsequent courses, when clinically indicated, have produced results similar to the initial course of therapy.
• Worsening of disease: Transient worsening of psoriasis may initially occur; patients should be advised that it may take 2-3 months to achieve the full benefits of treatment.
Lipid profile (baseline and at 1- to 2-week intervals for 4 to 8 weeks, then as clinically indicated); liver function tests (baseline, and at 1- to 2-week intervals until stable, then as clinically indicated); blood glucose in patients with diabetes; evaluate for bone abnormalities (with long-term use); pregnancy tests (2 negative tests prior to therapy initiation, monthly during treatment, and every 3 months for ≥3 years after discontinuation of therapy)
The American Academy of Dermatology recommends: CBC and renal function tests (baseline and then every 12 weeks); liver function tests (every 2 weeks for the first 8 weeks, then every 6 to 12 weeks thereafter) (Menter, 2009)
Pregnancy Risk Factor
[US Boxed Warning]: Acitretin is a known teratogen and use is contraindicated in females who are or may become pregnant. Birth defects (including facial, ear, central nervous system, cardiovascular, limb, bone, and joint) have been noted following acitretin exposure during pregnancy. Use only in women with severe psoriasis that is unresponsive to other therapies or with contraindications to the use of alternative treatments. Pregnancy must be avoided for at least 3 years after treatment discontinuation. Two reliable forms of contraception must be used simultaneously for 1 month prior to initiating therapy, during therapy, and for 3 years after discontinuation. Two negative pregnancy tests (sensitivity at least 25 milliunits/mL) are required prior to initiating therapy; pregnancy tests must be repeated every month during treatment. In addition, because ethanol forms a teratogenic metabolite and would increase the duration of teratogenic potential, ethanol should not be consumed during treatment or for 2 months after discontinuation.
Only physicians experienced with the diagnosis and treatment of severe psoriasis, including the use of retinoid treatment, and physicians who understand the risk of teratogenicity should prescribe acitretin. Females of childbearing potential must be able to fulfill all conditions for use prior to initiating therapy, including a Patient Agreement/Informed Consent (consult manufacturer's labeling for further detail).

Limited amounts of acitretin are found in seminal fluid; although it appears this poses little risk to a fetus, the actual risk of teratogenicity is not known.
Any pregnancy which occurs during treatment, or within 3 years after treatment is discontinued, should be reported to the manufacturer at 1-888-784-3335 or to the FDA at 1-800-FDA-1088.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience rhinorrhea, change in nails, xerostomia, dry mouth, dry lips, dry eyes, itching, or alopecia. Have patient report immediately to prescriber signs of liver problems (dark urine, feeling tired, lack of appetite, nausea, abdominal pain, light-colored stools, vomiting, or yellow skin or eyes), signs of depression (suicidal ideation, anxiety, emotional instability, illogical thinking), signs of high blood sugar (confusion, feeling sleepy, more thirst, hunger, passing urine more often, flushing, fast breathing, or breath that smells like fruit), anger, behavioral changes, angina, severe dizziness, passing out, strength differences from one side to another, difficulty speaking or thinking, change in balance, blurred vision, burning or numbness feeling, swelling of arm or leg, severe headache, severe nausea, vomiting, muscle pain, bone pain, arthralgia, vision changes, eye pain, severe eye irritation, contact lens discomfort, edema, weight gain, signs of a pancreas problem (pancreatitis) (severe abdominal pain, severe back pain, severe nausea, vomiting), poor night vision, or signs of severe skin problems (red, blistered, or swollen skin; peeling skin; itchy or painful skin) (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
