Suppresses cell-mediated immune reactions and some humoral immunity, but exact mechanism is not known. The mechanism of action in atopic dermatitis is not known.
In healthy volunteers, as well as kidney and liver transplant patients, tacrolimus C max ranged from approximately 19.2 to 68.5 ng/mL, T max ranged from 1.5 to 3 h, AUC ranged from 203 to 3,300 ng•h/mL, half-life ranged from 11.7 to 34.8 h, and bioavailability ranged from approximately 17% to 23%.Food effects
The rate and extent of absorption were greatest under fasted conditions. The presence and composition of food decreased the rate and extent of absorption. The effect was most pronounced with a high-fat meal. Mean AUC and C max were decreased 37% and 77%, respectively. T max was lengthened 5-fold. A high-carbohydrate meal decreased mean AUC and mean C max 28% and 65%, respectively.
Tacrolimus Vd is approximately 0.85 to 1.94 L/kg. Protein binding is about 99%, mainly to albumin and alpha-1 acid glycoprotein.
Tacrolimus is extensively metabolized by the mixed function oxidation system, primarily the CYP-450 system (CYP3A). The major metabolite identified is 13-demethyl tacrolimus.
Cl is about 0.04 to 0.083 L/h/kg. Less than 1% of an administered dose is excreted unchanged in the urine. The half-life is approximately 31.9 to 48.4 h (PO and IV).
Special PopulationsHepatic Function Impairment
The mean Cl was substantially lower and half-life prolonged in patients with severe hepatic impairment.Children
Children younger than 12 yr of age need higher doses than adults to achieve similar trough concentrations.Gender
No pharmacokinetic differences have been identified.Race
Kidney transplant patients who are black require a higher tacrolimus dose to attain trough concentrations similar to white patients.
Indications and UsagePO and IV
Prophylaxis of organ rejection in patients receiving allogenic liver, kidney, or heart transplants. Used in conjunction with adrenal corticosteroids. Used in conjunction with azathioprine or mycophenolate mofetil in heart and kidney transplant patients.Topical
As second-line therapy for the short-term and noncontinuous long-term treatment of moderate to severe atopic dermatitis.
Unlabeled UsesPO and IV
Prophylaxis of rejection for patients receiving bone marrow, pancreas, pancreatic island cell, and small bowel transplantation; treatment of autoimmune disease (ie, rheumatoid arthritis); prevention and treatment of acute graft-versus-host disease following hematopoietic stem cell transplantation; treatment of Crohn disease; treatment of pyoderma gangrenosum.Topical
Treatment of vitiligo; cutaneous lupus erythematosis; facial, flexural, and intertriginous psoriasis; oral or genital lichen planus; pyoderma gangrenosum.
