Prophylaxis of transplant rejection in cardiac allograft recipients

Active Ingredient: Tacrolimus

Indication for Tacrolimus

Population group: only children (1 year - 12 years old) , adolescents (12 years - 18 years old)
Therapeutic intent: Preventive action

For this indication, competent medicine agencies globally authorize below treatments:

0.03-0.05 mg/kg/day as a continuous 24-hour infusion

Route of admnistration

Intravenous

Defined daily dose

0.03 - 0.05 mg per kg of body weight

Dosage regimen

From 0.03 To 0.05 mg per kg of body weight once every day

Detailed description

Tacrolimus has been used with or without antibody induction in paediatric heart transplantation.

In patients without antibody induction, if tacrolimus therapy is initiated intravenously, the recommended starting dose is 0.03-0.05 mg/kg/day as a continuous 24-hour infusion targeted to achieve tacrolimus whole blood concentrations of 15-25 ng/ml. Patients should be converted to oral therapy as soon as clinically practicable. The first dose of oral therapy should be 0.30 mg/kg/day starting 8 to 12 hours after discontinuing intravenous therapy.

Following antibody induction, if tacrolimus therapy is initiated orally, the recommended starting dose is 0.10-0.30 mg/kg/day administered as two divided doses (e.g. morning and evening).

Dosage considerations

The concentration of a solution for infusion should be within the range 0.004-0.100 mg/ml. The total volume of infusion during a 24-hour period should be in the range 20–500 ml.

The diluted solution should not be given as a bolus.

0.1-0.3 mg/kg/day in 2 divided doses daily

Route of admnistration

Oral

Defined daily dose

0.1 - 0.3 mg per kg of body weight

Dosage regimen

From 0.05 To 0.15 mg per kg of body weight 2 time(s) per day every day

Following antibody induction, if tacrolimus therapy is initiated orally, the recommended starting dose is 0.10-0.30 mg/kg/day administered as two divided doses (e.g. morning and evening).

Tacrolimus doses are usually reduced in the post-transplant period. Post-transplant improvement in the condition of the patient may alter the pharmacokinetics of tacrolimus and may necessitate further dose adjustments.

Dosage considerations

The capsules should be swallowed with fluid (preferably water).

Capsules should generally be administered on an empty stomach or at least 1 hour before or 2 to 3 hours after a meal, to achieve maximal absorption.

Active ingredient

Tacrolimus

Tacrolimus is a highly potent immunosuppressive agent. In particular, tacrolimus inhibits the formation of cytotoxic lymphocytes, which are mainly responsible for graft rejection. Tacrolimus suppresses T-cell activation and T-helper-cell dependent B-cell proliferation, as well as the formation of lymphokines (such as interleukins-2, -3, and γ-interferon) and the expression of the interleukin-2 receptor.
