Dosage ADVAGRAF 3 mg Prolonged-release capsule Box of 30
Advagraf is a once-a-day oral formulation of tacrolimus. Treatment with Advagraf requires close supervision by medical staff with the necessary skills and equipment. Only physicians familiar with immunosuppressive drugs and experienced in the management of transplant patients are able to prescribe this drug and initiate changes in immunosuppressive therapy.
Inadvertent, unintentional or unadvised substitution between tacrolimus-containing immediate-release and sustained-release formulations is risky. This may result in graft rejection or an increase in the incidence of adverse effects, including under-immunosuppression or over-immunosuppression, due to clinically significant differences in systemic exposure to tacrolimus. Patients should be maintained under the same formulation containing tacrolimus with the corresponding daily dosing regimen; the formulation or dosing schedule should only be changed under the close supervision of a transplant specialist (see sections Warnings and precautions for use and Adverse reactions ). Following conversion to any other formulation, therapeutic drug monitoring should be performed and dose adjustments initiated to maintain systemic tacrolimus exposure.
The initial dosing recommendations presented below are for illustrative purposes only. Advagraf is generally given in combination with other immunosuppressive agents in the initial postoperative period. The dose may vary depending on the chosen immunosuppressive protocol. The dosage of Advagraf should be based primarily on the clinical evaluation of the signs of rejection and tolerance for each patient, aided by the monitoring of blood levels (see below "Drug Therapy Monitoring"). In the event of clinical signs of rejection, a modification of the immunosuppressive protocol should be considered.
In de novo renal and hepatic transplant patients, tacrolimus AUC 0- 24 for Advagraf on day 1 was, respectively, 30% and 50% lower than that obtained for immediate release capsule (Prograf) at equivalent doses. On the 4th day, the systemic exposure measured by the residual concentrations is similar in kidney transplant patients and in liver transplant patients with both formulations. Frequent and careful monitoring of residual concentrations of tacrolimus is recommended during the first two weeks after transplantation with A dvagraf to ensure adequate exposure to the drug in the immediate post-transplant period. Given the low clearance of tacrolimus, in case of dose adjustment, Advagraf's steady state may not appear until after several days.
Immunosuppression must be maintained to avoid rejection of the graft; therefore, no limitation of the duration of the oral treatment can be given.
Prevention of renal transplant rejection
Treatment with Advagraf will start at 0.20-0.30 mg / kg / day, once daily in the morning. Treatment should begin no later than 24 hours after transplantation.
In general, the dosage of Advagraf is reduced during the post-transplant period. It is possible in some cases to discontinue other concomitant immunosuppressive therapy and to use Advagraf as monotherapy. Changes in the patient's condition after transplantation may alter the pharmacokinetics of tacrolimus and may require subsequent dose adjustments.
Prevention of hepatic graft rejection
Treatment with Advagraf will start at 0.10-0.20 mg / kg / day, once daily in the morning. Treatment should begin approximately 12 to 18 hours after transplantation.
In general, the dosage of Advagraf is reduced during the post-transplant period. It is possible in some cases to discontinue other concomitant immunosuppressive therapy and to use Advagraf as monotherapy. Improving the patient's condition after transplantation may alter the pharmacokinetics of tacrolimus and may require subsequent dose adjustments.
Advagraf substitution of patients under Prograf
Advagraf substitution once daily in transplant patients maintained at the dosage of Prograf capsules twice daily should be based on a total daily dosage of 1: 1 (mg: mg). Advagraf should be given in the morning.
In stable patients converted from Prograf capsules (twice daily) to Advagraf (once daily) based on a total daily dosage of 1: 1 (mg: mg), systemic exposure to tacrolimus (AUC 0 -24 ) for Advagraf was about 10% lower than that of Prograf. The ratio of residual concentrations of tacrolimus (C 24 ) to systemic exposure (AUC 0-24 ) for Advagraf is similar to that of Prograf. When replacing Prograf capsules with Advagraf, the residual concentrations of tacrolimus must be measured before substitution and within two weeks of substitution. After substitution, residual concentrations of tacrolimus should be monitored and if necessary, dose adjustments should be made to maintain similar systemic exposure. Dose adjustments must be made to ensure that similar systemic exposure is maintained.
Replacement of ciclosporin with tacrolimus
Increased surveillance is recommended when replacing a ciclosporin-based protocol with a tacrolimus-based protocol (see sections Warnings and precautions for use and Interactions with other medicinal products and other forms of interaction ) . Concomitant administration of ciclosporin and tacrolimus is not recommended. Treatment with Advagraf should be initiated taking into account ciclosporin blood levels and the clinical status of the patient. Administration should be delayed in case of high blood concentrations of ciclosporin. In practice, tacrolimus therapy should be initiated 12-24 hours after discontinuation of ciclosporin. The monitoring of ciclosporin blood concentrations should continue after the substitution as the clearance of ciclosporin may be modified.
Treatment of allogeneic graft rejection
Increasing the dosage of tacrolimus, administering additional doses of corticosteroids, and introducing short courses of monoclonal or polyclonal antibodies have been used to treat rejection episodes. In case of signs of toxicity such as serious side effects (see section 4.8 ), it may be necessary to reduce the dose of Advagraf.
Treatment of allogeneic graft rejection after renal or hepatic transplantation If another immunosuppressant is switched from Advagraf once daily, treatment should begin at the recommended initial oral dose for the prevention of graft rejection, respectively in renal and hepatic transplantation. .
Treatment of allogeneic transplant rejection after cardiac transplantation
In adult patients converted to Advagraf, an initial oral dose of 0.15 mg / kg / day should be administered once daily in the morning.
Treatment of allogeneic graft rejection after transplantation of other grafts
Although there is no clinical experience with Advagraf in lung, pancreatic or intestinal transplantation, Prograf was used at initial oral doses of 0.10 - 0.15 mg / kg / day in lung transplantation, from 0, 2 mg / kg / day in pancreatic transplantation, and 0.3 mg / kg / day in intestinal transplantation.
Drug therapy monitoring
The dosage should be based primarily on clinical evaluation of the signs of rejection and tolerance for each patient using monitoring of residual concentrations of tacrolimus on whole blood.
To help optimize dosing, several immunoassay techniques are available to determine tacrolimus concentrations in whole blood. The comparison of the concentrations described in the literature with the individual values observed in clinical practice should be evaluated with caution and taking into account the dosing method used. Currently, in clinical practice, monitoring of whole blood concentrations is performed by immunoassay methods. The ratio between residual concentrations of tacrolimus (C 24 ) and systemic exposure (AUC 0-24) is similar between the two Advagraf and Prograf formulations.
Residual whole blood concentrations of tacrolimus should be monitored posttransplantation. Blood levels of tacrolimus should therefore be determined approximately 24 hours after the last dose of Advagraf and just before the next dose. Frequent monitoring of residual levels during the first two weeks after transplantation is recommended, followed by regular monitoring during maintenance treatment. Residual concentrations of tacrolimus should also be closely monitored following Advagraf's substitution of Prograf for all dose adjustments, following changes in the immunosuppressive protocol, or after concomitant administration of substances that may affect whole blood concentrations of tacrolimus. tacrolimus (see section Interactions with other medicinal products and other forms of interaction ). The periodicity of concentration monitoring should be based on clinical status. Due to the low clearance of tacrolimus, in the case of Advagraf dosage adjustment, the target steady state may occur only after several days.
Data from clinical studies suggest that when residual blood concentrations of tacrolimus are kept below 20 ng / ml, the majority of patients can be treated effectively. It is necessary to consider the clinical condition of the patient when interpreting product concentrations in whole blood. In clinical practice, residual whole blood concentrations generally range between 5-20 ng / ml in liver transplant recipients and 10-20 ng / ml in renal and cardiac transplant patients in the immediate post-transplant period. During maintenance therapy, blood levels generally range from 5-15 ng / ml in liver, kidney and heart transplant recipients.
Special populations of patients Hepatic insufficiency
A dose reduction may be required in patients with severe hepatic impairment to maintain tacrolimus residual blood levels within the recommended range.
As the pharmacokinetics of tacrolimus are not affected by renal function (see section 5.2 ), no dose adjustment is required. However, due to the nephrotoxic potential of tacrolimus, it is recommended that renal function be closely monitored (including serum creatinine, creatinine clearance, and urinary flow monitoring).
Compared to Caucasian patients, black patients may require higher doses of tacrolimus to achieve similar residual concentrations.
Currently available data do not show that men and women require different doses to achieve similar residual levels.
Currently available data do not show the need for dose adjustment in older populations.
The safety and effectiveness of Advagraf in children under 18 years of age have not been established. Limited data are available but no dosage recommendations can be given.
Advagraf is an oral formulation of tacrolimus taken once daily. It is recommended to administer the daily oral dose of Advagraf once daily in the morning. Advagraf Prolonged-Release Capsules should be taken immediately after removal from the blister pack. Patients should be warned not to swallow the desiccant. The capsules should be swallowed whole with a liquid (preferably water). In general, Advagraf should be taken on an empty stomach or at least 1 hour before or 2 to 3 hours after a meal to allow maximum absorption (see section Pharmacokinetic properties ). A missed dose in the morning should be taken as soon as possible on the same day. A double dose should not be taken the next morning.
For patients who can not take oral medications during the immediate posttransplantation period, tacrolimus therapy may be initiated intravenously (see Summary of Product Characteristics of Prograf 5 mg / ml concentrate for solution for infusion). the dose of approximately 1/5 th of the recommended oral dose for the corresponding indication.

Hypersensitivity to other macrolides
Advagraf side effects
The profile of adverse events associated with immunosuppressive therapy is often difficult to establish because of the underlying pathology and the concomitant use of many other drugs.
The most commonly reported adverse reactions (occurring in> 10% of patients) are tremor, renal function abnormalities, hyperglycemia, diabetes mellitus, hyperkalemia, infections, hypertension and insomnia.
The frequency of adverse events is defined as follows: very common (≥1 / 10); frequent (≥ 1/100, <1/10); uncommon (≥ 1/1000, <1/100); rare (≥ 1/10 000, <1/1000); very rare (<1 / 10, 000), not known (can not be estimated based on available data). Within each frequency group, adverse effects should be presented in order of decreasing severity.
