Usual Adult Dose for Organ Transplant- Rejection Prophylaxis

KIDNEY TRANSPLANT:

• In combination with azathioprine: Initial dose: 0.1 mg/kg orally every 12 hours. Initiate within 24 hours of surgery, but delay until renal function has recovered.
• In combination with mycophenolate mofetil (MMF)/interleukin (IL) receptor antagonist: Initial dose: 0.05 mg/kg orally every 12 hours. Initiate within 24 hours of surgery, but delay until renal function has recovered.

LIVER TRANSPLANT:

• Initial dose: 0.05 to 0.075 mg/kg orally every 12 hours. Initiate no sooner than 6 hours after surgery.

HEART TRANSPLANT:

• Initial dose: 0.0375 mg/kg orally every 12 hours. Initiate no sooner than 6 hours after surgery

Usual Pediatric Dose for Organ Transplant- Rejection Reversal

LIVER TRANSPLANT:

• Initial dose: 0.075 to 0.1 mg/kg orally every 12 hours

Pediatric Use: The safety and efficacy of Tacrolimus in pediatric kidney and heart transplant patients have not been established. Successful liver transplants have been performed in pediatric patients (ages up to 16 years) using Tacrolimus. Two randomized active-controlled trials of Tacrolimus in primary liver transplantation included 56 pediatric patients. Thirty-one patients were randomized to Tacrolimus-based and 25 to cyclosporine-based therapies. Additionally, a minimum of 122 pediatric patients were studied in an uncontrolled trial of Tacrolimus in living related donor liver transplantation. Pediatric patients generally required higher doses of Tacrolimus to maintain blood trough concentrations of Tacrolimus similar to adult patients.

Geriatric Use: Clinical trials of Tacrolimus did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

Use in Renal Impairment: The pharmacokinetics of Tacrolimus in patients with renal impairment was similar to that in healthy volunteers with normal renal function. However, consideration should be given to dosing Tacrolimus at the lower end of the therapeutic dosing range in patients who have received a liver or heart transplant and have pre-existing renal impairment. Further reductions in dose below the targeted range may be required

Use in Hepatic Impairment: The mean clearance of Tacrolimus was substantially lower in patients with severe hepatic impairment (mean Child-Pugh score: >10) compared to healthy volunteers with normal hepatic function. Close monitoring of Tacrolimus trough concentrations is warranted in patients with hepatic impairment.

The use of Tacrolimus in liver transplant recipients experiencing post-transplant hepatic impairment may be associated with increased risk of developing renal insufficiency related to high whole-blood trough concentrations of Tacrolimus. These patients should be monitored closely and dosage adjustments should be considered. Some evidence suggests that lower doses should be used in these patients
