For this indication, competent medicine agencies globally authorize below treatments:
Intravenous
0.05 - 0.1 mg per kg of body weight
From 0.05 To 0.1 mg per kg of body weight once every day
Oral tacrolimus therapy should commence at 0.20-0.30 mg/kg/day administered as two divided doses (e.g. morning and evening). Administration should commence within 24 hours after the completion of surgery.
If the dose cannot be administered orally as a result of the clinical condition of the patient, intravenous therapy of 0.05-0.10 mg/kg/day should be initiated as a continuous 24-hour infusion.
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.
Oral
0.2 - 0.3 mg per kg of body weight
From 0.1 To 0.15 mg per kg of body weight 2 time(s) per day every day
Oral tacrolimus therapy should commence at 0.20-0.30 mg/kg/day administered as two divided doses (e.g. morning and evening). Administration should commence within 24 hours after the completion of surgery.
If the dose cannot be administered orally as a result of the clinical condition of the patient, intravenous therapy of 0.05-0.10 mg/kg/day should be initiated as a continuous 24-hour infusion.
Tacrolimus doses are usually reduced in the post-transplant period. It is possible in some cases to withdraw concomitant immunosuppressive therapy, leading to tacrolimus-based dual-therapy. Post-transplant improvement in the condition of the patient may alter the pharmacokinetics of tacrolimus and may necessitate further dose adjustments.
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.
