Absorption is linear and proportional with increasing doses; approximately 72% is absorbed following a 50 mg dose. C max (mean 416 ng/mL) is achieved in 2 to 5 h.


Plasma protein binding is 99.9%, primarily to albumin.


Undergoes extensive metabolism to cis-acitretin.


Excreted in the feces (34% to 54%) and urine (16% to 53%). Terminal t ½ of acitretin is 49 h; t ½ of cis-acitretin is 63 h.

Special Populations


Higher plasma concentrations are seen; however, no changes occur in the t ½ .

Renal failure

Plasma concentrations are lower in end-stage renal failure. Acitretin is not removed by dialysis.

Indications and Usage

Treatment of severe psoriasis.


Pregnancy; severe liver or kidney function impairment; chronic abnormal elevation in blood lipid values; concurrent use of methotrexate or tetracyclines; hypersensitivity to other retinoids or any component of the product.

Dosage and Administration


PO Start with 25 to 50 mg/day given as a single dose with the main meal. Maintenance doses of 25 to 50 mg/day may be given dependent upon the patient's response to initial treatment.

Store capsules at controlled room temperature (59° to 77°F). Protect from light. Avoid exposure to high temperatures and humidity after bottle is opened.

Drug Interactions


Concurrent use of alcohol and acitretin may lead to the formation of etretinate, which increases the duration of teratogenic potential in women.


The glucose-lowering effect of glyburide may be potentiated.


Because the risk of hepatitis may be increased, concurrent use is contraindicated.


Protein binding of phenytoin may be reduced.

Progestin “minipill”

Acitretin may interfere with the contraceptive effect.


Because acitretin and tetracyclines can cause increased intracranial pressure, concurrent use is contraindicated.

Vitamin A, oral retinoids

Because the risk of hypervitaminosis A is increased, concurrent use is contraindicated.
