tacrolimus(redirected from Advagraf)
Pharmacologic class: Macrolide
Therapeutic class: Immunosuppressant
Pregnancy risk category C
FDA Box Warning
Immunosuppression may increase patient's susceptibility to infection and lymphoma development. Give under supervision of physician experienced in immunosuppressive therapy and management of organ transplant patients, in facility with adequate diagnostic and treatment resources. Physician responsible for maintenance therapy should have complete information needed for patient follow-up.
Be aware that long-term safety of topical calcineurin inhibitors hasn't been established.
Although a causal relationship hasn't been established, rare cases of malignancy (such as skin cancers and lymphoma) have been reported in patients treated with topical calcineurin inhibitors, including tacrolimus ointment. Therefore, continuous long-term use of tacrolimus ointment in any age-group should be avoided and application limited to areas of atopic dermatitis involvement. Tacrolimus ointment isn't indicated for use in children younger than age 2. Only 0.03% tacrolimus ointment is indicated for use in children ages 2 to 15.

• concurrent use of cyclosporine, nelfinavir, or live vaccines (avoid use)
• concurrent use of strong CYP3A4 inhibitors (such as boceprevir, clarithromycin, itraconazole, ketoconazole, ritonavir, telaprevir, voriconazole,) and strong inducers (such as rifampin, rifabutin) (not recommended)
• concurrent use of other substrates or CYP3A4 inhibitors that also have potential to prolong QT interval
• concurrent use of sirolimus (not recommended in liver and heart transplant; use with sirolimus in kidney transplant not established)
• concurrent use of other nephrotoxic drugs or drugs that cause hyperkalemia
• prolonged exposure to ultraviolet (UV) light and sunlight (avoid)
• pregnant or breastfeeding patients
• children younger than age 12 (age 2 for ointment use).
• Give oral form consistently with or without food but not with grapefruit juice.
• Give I.V. doses by infusion only. Be aware that I.V. use is reserved for patients who can't tolerate capsules orally.
• Start therapy within 24 hours of kidney transplantation and no earlier than 6 hours after liver or heart transplantation. Switch to oral dosing as soon as tolerable, starting 8 to 12 hours after I.V. dosing ends.
Before giving I.V., ensure that epinephrine 1:1,000 and oxygen are at hand in case of emergency.
• For I.V. use, dilute in normal saline solution or dextrose 5% in water to a concentration of 0.004 to 0.02 mg/ml. Give by infusion only.
• Be aware that ointment is used only as second-line therapy for the short-term and noncontinuous treatment of moderate to severe atopic dermatitis in nonimmunocompromised patients who have failed to respond adequately to other topical prescription treatments for atopic dermatitis.
• After applying ointment, don't place occlusive dressing or wrapping over affected area.

Once I.V. infusion starts, watch closely for signs and symptoms of anaphylaxis.

• Evaluate respiratory status regularly.
Teach patient to recognize and immediately report serious adverse reactions.
• Tell patient to take oral doses consistently with or without food, but not with grapefruit or grapefruit juice.
• Tell diabetic patient to expect increased blood glucose level, which may warrant further antidiabetic therapy. Advise him to monitor glucose level carefully.
• Instruct patient not to place occlusive dressings or wrappings over affected area after applying ointment. Tell him to use drug for 1 week after dermatitis symptoms resolve.
• Advise patient to avoid live vaccines and prolonged exposure to UV light or sunlight.
• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the drugs, tests, foods, and herbs mentioned above.

tacrolimusFK506, Prograf Immunology An immunosuppressant that inhibits IL-2 synthesis and binding; it is similar to, and synergistic with, cyclosporine, up to 50-fold more immunosuppressive than cyclosporine; it is used in BM, kidney, liver, lung, and other transplants Adverse effects Neurotoxicity–tremor, seizures, white matter disease, headache, nausea, paresthesias of hands, feet, insomnia; nephrotoxicity, hyperglycemia, hirsutism, paresthesia, ↑ lipids, ↑ K+, HUS, ↓ Mg2+. Cf Cyclosporine.
tacrolimusA potent immunosuppressant macrolide compound isolated from a bacterium. Tacrolimus is effective in reducing the risk of rejection of solid-organ transplants especially liver transplants. It has been successfully used as a monotherapy to prevent graft rejections and has virtually eliminated immunosuppression-related morbidity. It has also been found useful in ointment form for the treatment of moderate-to-severe atopic dermatitis in which it has been found as effective as strong topic steroids. Brand names are Prograf and Protopic.
drug class: immunosuppressant;
action: inhibits T-lymphocyte activation leading to immunosuppression;
use: prophylaxis of organ rejection in patients receiving allogenic liver transplants.
