High tacrolimus blood concentrations early after lung transplantation and the risk of kidney injury. We aimed to identify the tacrolimus level associated with better outcomes in lung transplant patients. This has a major impact on tacrolimus bioavailability, since intraluminal transport to the duodenum is limited, being its predominant site of intestinal absorption. RESULTS: The mean tacrolimus dose during itraconazole treatment was 3.26 ± 2.1 mg/d compared with 5.74 ± 2.9 mg/d after itraconazole was stopped, p < 0.0001.

Tacrolimus levels and dosage requirements were compared during and after azole therapy.
Evolution to twice daily bolus intravenous tacrolimus: optimizing efficacy and safety of calcineurin inhibitor delivery early post lung transplant. Two underlying mechanisms are suggested. This review provides initial guidance to clinicians in adjusting tacrolimus dosing regimens on the basis of these bio‐variables.We would like to thank the following people for providing the figures. , High tacrolimus blood concentrations early after lung transplantation and the risk of kidney injury, Protective effects of green tea and its main constituents against natural and chemical toxins: A comprehensive review, An Elastomeric Polymer Matrix, PEUU-Tac, Delivers Bioactive Tacrolimus Transdurally to the CNS in Rat, Pharmacokinetic considerations related to therapeutic drug monitoring of tacrolimus in kidney transplant patients, Development of a Simple and Rapid Method to Measure the Free Fraction of Tacrolimus in Plasma Using Ultrafiltration and LC-MS/MS, A Worldwide Yearly Survey of New Data in Adverse Drug Reactions, Prograf Concentrations in Liver Transplantation: Correlation With Headache and Other Neurotoxic Complications?, Letter to the editor: “Immunosuppressive drug therapy – biopharmaceutical challenges and remedies”, The Evaluation and Therapeutic Management of Hypertension in the Transplant Patient, However, morbidity and mortality still pose a major concern. 1, 144 . 2019;41:261–307.Zahir H, McCaughan G, Gleeson M, Nand RA, McLachlan AJ.

Moreover, whole blood trough levels are difficult to predict and are poorly related to the area under the concentration‐time curve. Transpl Proc. 2010 Apr;49(4):207-21. doi: 10.2165/11317550-000000000-00000.Clin Pharmacokinet. We categorized ABCB1, CYP3A4, and CYP3A5 SNPs for 321 lung allograft recipients. J Heart Lung Transplant 2002 ; 21 : Suppl. At this time of clinical instability, the kidneys are exposed to numerous nephrotoxic stimuli. Although the unbound concentration is known to be related to hematocrit, studies investigating the unbound tacrolimus plasma concentrations are scarce because quantification of unbound tacrolimus concentrations is bioanalytically challenging, costly, and time-consuming [Because of the large influence of hematocrit on whole-blood concentrations, hematocrit-corrected whole-blood concentrations may be suitable as a substitute for the prediction of clinical outcomes.
Published by John Wiley & Sons Ltd. The SNP in the SLCO1B1 gene 521T>C significantly increases tacrolimus blood concentrations and the SNP 388A>G significantly decreases tacrolimus blood concentrations The bioavailability of tacrolimus has been found to be approximately 15%, though it may widely vary in healthy persons due to the aforementioned phenomena The binding of tacrolimus to blood components is an important factor in its pharmacokinetics In more detail, tacrolimus is strongly bound to the cytosolic proteins cyclophilin and FK506 binding protein within the red blood cells Tacrolimus is mainly metabolized in the liver, but also in the gut and kidney. This is my second transplant.
