Maribavir was approved by the FDA in November 2021, under the name Livtencity (Takeda), for the treatment of resistant CMV infections in post-transplant patients.[L39327] The drug was also approved by Health Canada in September 2022 [L43262] and by European Commission in November 2022.[L44411]
[L39322][L43262][L44406]
In the US, patients receiving the treatment should weigh more than 35 kg and be at least 12 years old.
[L39322]
In Canada and Europe, maribavir is only approved in adults.

As maribavir is extensively protein-bound in plasma, dialysis is unlikely to be of benefit.
[L39322]
Maribavir belongs to a class of anti-cytomegalovirus antivirals called benzimidazole ribosides.[A242512] It competitively inhibits the human CMV pUL97 viral protein kinase, which results in viable but severely defective viruses upon replication,[A242557] although the reasons for this remain poorly defined. In addition, maribavir also inhibits viral release from the nucleus to the cytoplasm by inhibiting pUL97-dependent phosphorylation of the nuclear lamina component lamin A/C, although the extent to which this activity contributes to its antiviral efficacy is unclear.[A242557]
Maribavir should not be used concomitantly with ganciclovir or valganciclovir, as these molecules both require activation via CMV pUL97 in order to exert their antiviral effect. Taking them alongside maribavir - an inhibitor of this same kinase - will therefore significantly reduce their antiviral activity.[L39322]

Involved in porphyrin homeostasis, mediating the export of protoporphyrin IX (PPIX) from both mitochondria to cytosol and cytosol to extracellular space, it also functions in the cellular export of heme .
PMID:20705604 PMID:23189181
Also mediates the efflux of sphingosine-1-P from cells .
PMID:20110355
Acts as a urate exporter functioning in both renal and extrarenal urate excretion .
PMID:19506252 PMID:20368174 PMID:22132962 PMID:31003562 PMID:36749388
In kidney, it also functions as a physiological exporter of the uremic toxin indoxyl sulfate (By similarity). Also involved in the excretion of steroids like estrone 3-sulfate/E1S, 3beta-sulfooxy-androst-5-en-17-one/DHEAS, and other sulfate conjugates .
PMID:12682043 PMID:28554189 PMID:30405239
Mediates the secretion of the riboflavin and biotin vitamins into milk (By similarity). Extrudes pheophorbide a, a phototoxic porphyrin catabolite of chlorophyll, reducing its bioavailability (By similarity).
Plays an important role in the exclusion of xenobiotics from the brain (Probable). It confers to cells a resistance to multiple drugs and other xenobiotics including mitoxantrone, pheophorbide, camptothecin, methotrexate, azidothymidine, and the anthracyclines daunorubicin and doxorubicin, through the control of their efflux .
PMID:11306452 PMID:12477054 PMID:15670731 PMID:18056989 PMID:31254042
In placenta, it limits the penetration of drugs from the maternal plasma into the fetus (By similarity). May play a role in early stem cell self-renewal by blocking differentiation (By similarity).
In inflammatory macrophages, exports itaconate from the cytosol to the extracellular compartment and limits the activation of TFEB-dependent lysosome biogenesis involved in antibacterial innate immune response
PMID:2897240 PMID:35970996 PMID:8898203 PMID:9038218 PMID:35507548
Catalyzes the flop of phospholipids from the cytoplasmic to the exoplasmic leaflet of the apical membrane. Participates mainly to the flop of phosphatidylcholine, phosphatidylethanolamine, beta-D-glucosylceramides and sphingomyelins .

Proteins that carry this drug through the body
PMID:19021548
Major calcium and magnesium transporter in plasma, binds approximately 45% of circulating calcium and magnesium in plasma (By similarity).
Potentially has more than two calcium-binding sites and might additionally bind calcium in a non-specific manner (By similarity). The shared binding site between zinc and calcium at residue Asp-273 suggests a crosstalk between zinc and calcium transport in the blood (By similarity). The rank order of affinity is zinc > calcium > magnesium (By similarity).
Binds to the bacterial siderophore enterobactin and inhibits enterobactin-mediated iron uptake of E.coli from ferric transferrin, and may thereby limit the utilization of iron and growth of enteric bacteria such as E.coli .
PMID:6234017
Does not prevent iron uptake by the bacterial siderophore aerobactin PMID:6234017
Appears to function in modulating the activity of the immune system during the acute-phase reaction
