1 INDICATIONS AND USAGE Voriconazole tablets are an azole antifungal indicated for the treatment of adults and pediatric patients 2 years of age and older with: Invasive aspergillosis ( 1.1 ) Candidemia in non-neutropenics and other deep tissue Candida infections ( 1.2 ) Esophageal candidiasis ( 1.3 ) Serious fungal infections caused by Scedosporium apiospermum and Fusarium species including Fusarium solani , in patients intolerant of, or refractory to, other therapy ( 1.4 )
1.1Invasive Aspergillosis Voriconazole tablets are indicated in adults and pediatric patients (2 years of age and older) for the treatment of invasive aspergillosis (IA). In clinical trials, the majority of isolates recovered were Aspergillus fumigatus . There was a small number of cases of culture-proven disease due to species of Aspergillus other than A. fumigatus [see Clinical Studies (14.1 , 14.5) and Microbiology (12.4) ] .
1.2Candidemia in Non-neutropenic Patients and Other Deep Tissue Candida Infections Voriconazole tablets are indicated in adults and pediatric patients (2 years of age and older) for the treatment of candidemia in non-neutropenic patients and the following Candida infections: disseminated infections in skin and infections in abdomen, kidney, bladder wall, and wounds [see Clinical Studies (14.2 , 14.5) and Microbiology (12.4) ] .
1.3Esophageal Candidiasis Voriconazole tablets are indicated in adults and pediatric patients (2 years of age and older) for the treatment of esophageal candidiasis (EC) in adults and pediatric patients 2 years of age and older [see Clinical Studies (14.3 , 14.5) and Microbiology (12.4) ] .
1.4Scedosporiosis and Fusariosis Voriconazole tablets are indicated for the treatment of serious fungal infections caused by Scedosporium apiospermum (asexual form of Pseudallescheria boydii ) and Fusarium spp. including Fusarium solani , in adults and pediatric patients (2 years of age and older) intolerant of, or refractory to, other therapy [see Clinical Studies (14.4) and Microbiology (12.4) ] .
1.5Usage Specimens for fungal culture and other relevant laboratory studies (including histopathology) should be obtained prior to therapy to isolate and identify causative organism(s). Therapy may be instituted before the results of the cultures and other laboratory studies are known. However, once these results become available, antifungal therapy should be adjusted accordingly.

2.1Important Administration Instructions for Use in All Patients Administer voriconazole tablets at least one hour before or after a meal.
2.3Recommended Dosing Regimen in Adults Invasive aspergillosis and serious fungal infections due to Fusarium spp. and Scedosporium apiospermum See Table 1. Therapy must be initiated with the specified loading dose regimen of intravenous voriconazole on Day 1 followed by the recommended maintenance dose (RMD) regimen. Intravenous treatment should be continued for at least 7 days.
Once the patient has clinically improved and can tolerate medication given by mouth, the oral tablet form or oral suspension form of voriconazole may be utilized. The recommended oral maintenance dose of 200 mg achieves a voriconazole exposure similar to 3 mg/kg intravenously; a 300 mg oral dose achieves an exposure similar to 4 mg/kg intravenously [see Clinical Pharmacology (12.3) ] . Candidemia in non-neutropenic patients and other deep tissue Candida infections See Table 1.
Patients should be treated for at least 14 days following resolution of symptoms or following last positive culture, whichever is longer. Esophageal Candidiasis See Table 1. Patients should be treated for a minimum of 14 days and for at least 7 days following resolution of symptoms.

⛔ Contraindications ▾
4 CONTRAINDICATIONS Voriconazole tablets are contraindicated in patients with known hypersensitivity to voriconazole or its excipients. There is no information regarding cross-sensitivity between voriconazole and other azole antifungal agents. Caution should be used when prescribing voriconazole tablets to patients with hypersensitivity to other azoles.
Coadministration of pimozide, quinidine or ivabradine with voriconazole tablets is contraindicated because increased plasma concentrations of these drugs can lead to QT prolongation and rare occurrences of torsade de pointes [see Drug Interactions (7) ] . Coadministration of voriconazole tablets with sirolimus is contraindicated because voriconazole tablets significantly increases sirolimus concentrations [see Drug Interactions (7) and Clinical Pharmacology (12.3) ] . Coadministration of voriconazole tablets with rifampin, carbamazepine, long-acting barbiturates, and St John’s Wort is contraindicated because these drugs are likely to decrease plasma voriconazole concentrations significantly [see Drug Interactions (7) and Clinical Pharmacology (12.3) ] .
Coadministration of standard doses of voriconazole with efavirenz doses of 400 mg every 24 hours or higher is contraindicated, because efavirenz significantly decreases plasma voriconazole concentrations in healthy subjects at these doses. Voriconazole also significantly increases efavirenz plasma concentrations [see Drug Interactions (7) and Clinical Pharmacology (12.3) ] . Coadministration of voriconazole tablets with high-dose ritonavir (400 mg every 12 hours) is contraindicated because ritonavir (400 mg every 12 hours) significantly decreases plasma voriconazole concentrations.
Coadministration of voriconazole and low-dose ritonavir (100 mg every 12 hours) should be avoided, unless an assessment of the benefit/risk to the patient justifies the use of voriconazole [see Drug Interactions (7) and Clinical Pharmacology (12.3) ] . Coadministration of voriconazole tablets with rifabutin is contraindicated since voriconazole tablets significantly increases rifabutin plasma concentrations and rifabutin also significantly decreases voriconazole plasma concentrations [see Drug Interactions (7) and Clinical Pharmacology (12.3) ] .
Coadministration of voriconazole tablets with ergot alkaloids (ergotamine and dihydroergotamine) is contraindicated because voriconazole tablets may increase the plasma concentration of ergot alkaloids, which may lead to ergotism [see Drug Interactions (7) ] . Coadministration of voriconazole tablets with naloxegol is contraindicated because voriconazole tablets may increase plasma concentrations of naloxegol which may precipitate opioid withdrawal symptoms [see Drug Interactions (7) ]. Coadministration of voriconazole tablets with tolvaptan is contraindicated because voriconazole tablets may increase tolvaptan plasma concentrations and increase risk of adverse reactions [see Drug Interactions (7) ].
Coadministration of voriconazole tablets with venetoclax at initiation and during the ramp-up phase is contraindicated in patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) due to the potential for increased risk of tumor lysis syndrome [see Drug Interactions (7) ]. Coadministration of voriconazole tablets with lurasidone is contraindicated since it may result in significant increases in lurasidone exposure and the potential for serious adverse reactions [see Drug Interactions (7) ].
Hypersensitivity to voriconazole or its excipients ( 4 ) Coadministration with pimozide, quinidine, sirolimus or ivabradine due to risk of serious adverse reactions ( 4 , 7 ) Coadministration with rifampin, carbamazepine, long-acting barbiturates, efavirenz, ritonavir, rifabutin, ergot alkaloids, and St. John’s Wort due to risk of loss of efficacy ( 4 , 7 ) Coadministration with naloxegol, tolvaptan, and lurasidone due to risk of adverse reactions ( 4 , 7 ) Coadministration of voriconazole with venet…
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Hepatic Toxicity : Serious hepatic reactions reported. Evaluate liver function tests at start of and during voriconazole therapy (5.1) Arrhythmias and QT Prolongation : Correct potassium, magnesium and calcium prior to use; caution patients with proarrhythmic conditions (5.2) Infusion Related Reactions (including anaphylaxis) : Stop the infusion (5.3) Visual Disturbances (including optic neuritis and papilledema): Monitor visual function if treatment continues beyond 28 days (5.4) Severe Cutaneous Adverse Reactions : Discontinue for exfoliative cutaneous reactions (5.5) Photosensitivity: Avoid sunlight due to risk of photosensitivity (5.6) Adrenal Dysfunction: Carefully monitor patients receiving voriconazole and corticosteroids (via all routes of administration) for adrenal dysfunction both during and after voriconazole treatment.
Instruct patients to seek immediate medical care if they develop signs and symptoms of Cushing’s syndrome or adrenal insufficiency ( 5.8 ) Embryo-Fetal Toxicity : Voriconazole can cause fetal harm when administered to a pregnant woman. Inform pregnant patients of the potential hazard to the fetus. Advise females of reproductive potential to use effective contraception during treatment with voriconazole tablets ( 5.9 , 8.1 , 8.3) Skeletal Adverse Reactions : Fluorosis and periostitis with long-term voriconazole therapy.
Discontinue if these adverse reactions occur ( 5.12 ) Clinically Significant Drug Interactions : Review patient’s concomitant medications ( 5.13 , 7) Patients with Hereditary Galactose Intolerance, Lapp Lactase Deficiency or Glucose-Galactose Malabsorption : Voriconazole tablets should not be given to these patients because it contains lactose ( 5.14 )
5.1Hepatic Toxicity In clinical trials, there have been uncommon cases of serious hepatic reactions during treatment with voriconazole (including clinical hepatitis, cholestasis and fulminant hepatic failure, including fatalities). Instances of hepatic reactions were noted to occur primarily in patients with serious underlying medical conditions (predominantly hematological malignancy). Hepatic reactions, including hepatitis and jaundice, have occurred among patients with no other identifiable risk factors.
Liver dysfunction has usually been reversible on discontinuation of therapy [see Adverse Reactions (6.1) ] . A higher frequency of liver enzyme elevations was observed in the pediatric population [see Adverse Reactions (6.1) ]. Hepatic function should be monitored in both adult and pediatric patients.
Measure serum transaminase levels and bilirubin at the initiation of voriconazole therapy and monitor at least weekly for the first month of treatment. Monitoring frequency can be reduced to monthly during continued use if no clinically significant changes are noted. If liver function tests become markedly elevated compared to baseline, voriconazole should be discontinued unless the medical judgment of the benefit/risk of the treatment for the patient justifies continued use [see Dosage and Administration (2.5) and Adverse Reactions (6.1) ] .
5.2Arrhythmias and QT Prolongation Some azoles, including voriconazole, have been associated with prolongation of the QT interval on the electrocardiogram. During clinical development and postmarketing surveillance, there have been rare cases of arrhythmias, (including ventricular arrhythmias such as torsade de pointes ), cardiac arrests and sudden deaths in patients taking voriconazole. These cases usually involved seriously ill patients with multiple confounding risk factors, such as history of cardiotoxic chemotherapy, cardiomyopathy, hypokalemia and concomitant medications that may have been contributory.
Voriconazole should be administered with caution to patients with potentially proarrhythmic conditions, such as: Congenital or acquired QT prolongation Cardiomyopathy, in particular when heart failure is present Sinus bradycardia Existing symptomatic arrhythmias Co…

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Clinical Trials Experience in Adults Overview The most frequently reported adverse reactions (see Table 4) in the adult therapeutic trials were visual disturbances (18.7%), fever (5.7%), nausea (5.4%), rash (5.3%), vomiting (4.4%), chills (3.7%), headache (3%), liver function test increased (2.7%), tachycardia (2.4%), hallucinations (2.4%).
The adverse reactions which most often led to discontinuation of voriconazole therapy were elevated liver function tests, rash, and visual disturbances [see Warning and Precautions (5.1 , 5.4) and Adverse Reactions (6.1) ]. The data described in Table 4 reflect exposure to voriconazole in 1655 patients in nine therapeutic studies. This represents a heterogeneous population, including immunocompromised patients, e.g., patients with hematological malignancy or HIV and non-neutropenic patients.
This subgroup does not include healthy subjects and patients treated in the compassionate use and non-therapeutic studies. This patient population was 62% male, had a mean age of 46 years (range 11 to 90, including 51 patients aged 12 to 18 years), and was 78% White and 10% Black. Five hundred sixty one patients had a duration of voriconazole therapy of greater than 12 weeks, with 136 patients receiving voriconazole for over six months.
Table 4 includes all adverse reactions which were reported at an incidence of ≥2% during voriconazole therapy in the all therapeutic studies population, studies 307/602 and 608 combined, or study 305, as well as events of concern which occurred at an incidence of <2%. In study 307/602, 381 patients (196 on voriconazole, 185 on amphotericin B) were treated to compare voriconazole to amphotericin B followed by other licensed antifungal therapy (OLAT) in the primary treatment of patients with acute IA. The rate of discontinuation from voriconazole study medication due to adverse reactions was 21.4% (42/196 patients).
In study 608, 403 patients with candidemia were treated to compare voriconazole (272 patients) to the regimen of amphotericin B followed by fluconazole (131 patients). The rate of discontinuation from voriconazole study medication due to adverse reactions was 19.5% out of 272 patients. Study 305 evaluated the effects of oral voriconazole (200 patients) and oral fluconazole (191 p…
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Voriconazole is metabolized by cytochrome P450 isoenzymes, CYP2C19, CYP2C9, and CYP3A4. Therefore, inhibitors or inducers of these isoenzymes may increase or decrease voriconazole plasma concentrations, respectively. Voriconazole is a strong inhibitor of CYP3A4, and also inhibits CYP2C19 and CYP2C9.
Therefore, voriconazole may increase the plasma concentrations of substances metabolized by these CYP450 isoenzymes. Tables 10 and 11 provide the clinically significant interactions between voriconazole and other medical products. Table 10: Effect of Other Drugs on Voriconazole Pharmacokinetics [see Clinical Pharmacology (12.3) ] Drug/Drug Class (Mechanism of Interaction by the Drug) Voriconazole Plasma Exposure (C max and AUC τ after 200 mg every 12 hours) Recommendations for Voriconazole Dosage Adjustment/Comments Rifampin* and Rifabutin* (CYP450 Induction) Significantly Reduced Contraindicated Efavirenz (400 mg every 24 hours)** (CYP450 Induction) Efavirenz (300 mg every 24 hours)** (CYP450 Induction) Significantly Reduced Slight Decrease in AUCτ Contraindicated When voriconazole is coadministered with efavirenz, voriconazole oral maintenance dose should be increased to 400 mg every 12 hours and efavirenz should be decreased to 300 mg every 24 hours.
High-dose Ritonavir (400 mg every 12 hours)** (CYP450 Induction) Low-dose Ritonavir (100 mg every 12 hours)** (CYP450 Induction) Significantly Reduced Reduced Contraindicated Coadministration of voriconazole and low-dose ritonavir (100 mg every 12 hours) should be avoided, unless an assessment of the benefit/risk to the patient justifies the use of voriconazole. Carbamazepine (CYP450 Induction) Not Studied In Vivo or In Vitro , but Likely to Result in Significant Reduction Contraindicated Long Acting Barbiturates (e.g., phenobarbital, mephobarbital) (CYP450 Induction) Not Studied In Vivo or In Vitro , but Likely to Result in Significant Reduction Contraindicated Phenytoin* (CYP450 Induction) Significantly Reduced Increase voriconazole maintenance dose from 4 mg/kg to 5 mg/kg IV every 12 hours or from 200 mg to 400 mg orally every 12 hours (100 mg to 200 mg orally every 12 hours in patients weighing less than 40 kg).
Letermovir (CYP2C9/2C19 Induction) Reduced If concomitant administration of voriconazole with letermovir cannot be avoided, monitor for reduced effectiveness of voriconazole. St. John’s Wort (CYP450 inducer; P-gp inducer) Significantly Reduced Contraindicated Oral Contraceptives** containing ethinyl estradiol and norethindrone (CYP2C19 Inhibition) Increased Monitoring for adverse reactions and toxicity related to voriconazole is recommended when coadministered with oral contraceptives.
Fluconazole** (CYP2C9, CYP2C19 and CYP3A4 Inhibition) Significantly Increased Avoid concomitant administration of voriconazole and fluconazole. Monitoring for adverse reactions and toxicity related to voriconazole is started within 24 hours after the last dose of fluconazole. Other HIV Protease Inhibitors (CYP3A4 Inhibition) In Vivo Studies Showed No Significant Effects of Indinavir on Voriconazole Exposure In Vitro Studies Demonstrated Potential for Inhibition of Voriconazole Metabolism (Increased Plasma Exposure) No dosage adjustment in the voriconazole dosage needed when coadministered with indinavir.

8.1Pregnancy Risk Summary Voriconazole can cause fetal harm when administered to a pregnant woman. There are no available data on the use of voriconazole in pregnant women. In animal reproduction studies, oral voriconazole was associated with fetal malformations in rats and fetal toxicity in rabbits.
Cleft palates and hydronephrosis/hydroureter were observed in rat pups exposed to voriconazole during organogenesis at and above 10 mg/kg (0.3 times the RMD of 200 mg every 12 hours based on body surface area comparisons). In rabbits, embryomortality, reduced fetal weight and increased incidence of skeletal variations, cervical ribs and extrasternal ossification sites were observed in pups when pregnant rabbits were orally dosed at 100 mg/kg (6 times the RMD based on body surface area comparisons) during organogenesis.
Rats exposed to voriconazole from implantation to weaning experienced increased gestational length and dystocia, which were associated with increased perinatal pup mortality at the 10 mg/kg dose [see Data]. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, inform the patient of the potential hazard to the fetus [see Warnings and Precautions (5.9) ]. The background risk of major birth defects and miscarriage for the indicated populations is unknown.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20% respectively. Data Animal Data Voriconazole was administered orally to pregnant rats during organogenesis (gestation days 6 to 17) at 10, 30, and 60 mg/kg/day. Voriconazole was associated with increased incidences of the malformations hydroureter and hydronephrosis at 10 mg/kg/day or greater, approximately 0.3 times the recommended human dose (RMD) based on body surface area comparisons, and cleft palate at 60 mg/kg, approximately 2 times the RMD based on body surface area comparisons.
Reduced ossification of sacral and caudal vertebrae, skull, pubic, and hyoid bone, supernumerary ribs, anomalies of the sternebrae, and dilatation of the ureter/renal pelvis were also observed at doses of 10 mg/kg or greater. There was no evidence of maternal toxicity at any dose. Voriconazole was administered orally to pregnant rabbits during the period of organogenesis (gestation days 7 to 19) at 10, 40, and 100 mg/kg/day.
Voriconazole was associated with increased post-implantation loss and decreased fetal body weight, in association with maternal toxicity (decreased body weight gain and food consumption) at 100 mg/kg/day (6 times the RMD based on body surface area comparisons). Fetal skeletal variations (increases in the incidence of cervical rib and extra sternebral ossification sites) were observed at 100 mg/kg/day. In a peri- and postnatal toxicity study in rats, voriconazole was administered orally to female rats from implantation through the end of lactation at 1, 3, and 10 mg/kg/day.
Voriconazole prolonged the duration of gestation and labor and produced dystocia with related increases in maternal mortality and decreases in perinatal survival of F1 pups at 10 mg/kg/day, approximately 0.3 times the RMD.
8.2Lactation Risk Summary No data are available regarding the presence of voriconazole in human milk, the effects of voriconazole on the breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for voriconazole and any potential adverse effects on the breastfed child from voriconazole or from the underlying maternal condition.

8.1Pregnancy Risk Summary Voriconazole can cause fetal harm when administered to a pregnant woman. There are no available data on the use of voriconazole in pregnant women. In animal reproduction studies, oral voriconazole was associated with fetal malformations in rats and fetal toxicity in rabbits.
Cleft palates and hydronephrosis/hydroureter were observed in rat pups exposed to voriconazole during organogenesis at and above 10 mg/kg (0.3 times the RMD of 200 mg every 12 hours based on body surface area comparisons). In rabbits, embryomortality, reduced fetal weight and increased incidence of skeletal variations, cervical ribs and extrasternal ossification sites were observed in pups when pregnant rabbits were orally dosed at 100 mg/kg (6 times the RMD based on body surface area comparisons) during organogenesis.
Rats exposed to voriconazole from implantation to weaning experienced increased gestational length and dystocia, which were associated with increased perinatal pup mortality at the 10 mg/kg dose [see Data]. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, inform the patient of the potential hazard to the fetus [see Warnings and Precautions (5.9) ].

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and effectiveness of voriconazole have been established in pediatric patients 2 years of age and older based on evidence from adequate and well-controlled studies in adult and pediatric patients and additional pediatric pharmacokinetic and safety data. A total of 105 pediatric patients aged 2 to less than 12 [N=26] and aged 12 to less than 18 [N=79] from two, non-comparative Phase 3 pediatric studies and eight adult therapeutic trials provided safety information for voriconazole use in the pediatric population [see Adverse Reactions (6.1) , Clinical Pharmacology (12.3) , and Clinical Studies (14) ].
Safety and effectiveness in pediatric patients below the age of 2 years has not been established. Therefore, voriconazole is not recommended for pediatric patients less than 2 years of age. A higher frequency of liver enzyme elevations was observed in the pediatric patients [see Dosage and Administration (2.5) , Warnings and Precautions (5.1) , and Adverse Reactions (6.1) ].
The frequency of phototoxicity reactions is higher in the pediatric population. Squamous cell carcinoma has been reported in patients who experience photosensitivity reactions. Stringent measures for photoprotection are warranted.
Sun avoidance and dermatologic follow-up are recommended in pediatric patients experiencing photoaging injuries, such as lentigines or ephelides, even after treatment discontinuation [see Warnings and Precautions (5.6) ]. Voriconazole has not been studied in pediatric patients with hepatic or renal impairment [see Dosage and Administration (2.5 , 2.6) ]. Hepatic function and serum creatinine levels should be closely monitored in pediatric patients [see Dosage and Administration (2.6) and Warnings and Precautions (5.1 , 5.10) ].
🧓 Geriatric Use ▾
8.5Geriatric Use In multiple dose therapeutic trials of voriconazole, 9.2% of patients were ≥65 years of age and 1.8% of patients were ≥75 years of age. In a study in healthy subjects, the systemic exposure (AUC) and peak plasma concentrations (C max ) were increased in elderly males compared to young males. Pharmacokinetic data obtained from 552 patients from 10 voriconazole therapeutic trials showed that voriconazole plasma concentrations in the elderly patients were approximately 80% to 90% higher than those in younger patients after either IV or oral administration.
However, the overall safety profile of the elderly patients was similar to that of the young so no dosage adjustment is recommended [see Clinical Pharmacology (12.3) ] .
🆘 Overdosage ▾
10 OVERDOSAGE In clinical trials, there were three cases of accidental overdose. All occurred in pediatric patients who received up to five times the recommended intravenous dose of voriconazole. A single adverse reaction of photophobia of 10 minutes duration was reported.
There is no known antidote to voriconazole. Voriconazole is hemodialyzed with clearance of 121 mL/min. The intravenous vehicle, SBECD, is hemodialyzed with clearance of 55 mL/min.
In an overdose, hemodialysis may assist in the removal of voriconazole and SBECD from the body.

12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Voriconazole is an antifungal drug [see Microbiology (12.4) ].
12.2Pharmacodynamics Exposure-Response Relationship For Efficacy and Safety In 10 clinical trials (N=1121), the median values for the average and maximum voriconazole plasma concentrations in individual patients across these studies was 2.51 mcg/mL (inter-quartile range 1.21 to 4.44 mcg/mL) and 3.79 mcg/mL (inter-quartile range 2.06 to 6.31 mcg/mL), respectively. A pharmacokinetic-pharmacodynamic analysis of patient data from 6 of these 10 clinical trials (N=280) could not detect a positive association between mean, maximum or minimum plasma voriconazole concentration and efficacy.
However, pharmacokinetic/pharmacodynamic analyses of the data from all 10 clinical trials identified positive associations between plasma voriconazole concentrations and rate of both liver function test abnormalities and visual disturbances [see Adverse Reactions (6) ] . Cardiac Electrophysiology A placebo-controlled, randomized, crossover study to evaluate the effect on the QT interval of healthy male and female subjects was conducted with three single oral doses of voriconazole and ketoconazole. Serial ECGs and plasma samples were obtained at specified intervals over a 24-hour post dose observation period.
The placebo-adjusted mean maximum increases in QTc from baseline after 800, 1200, and 1600 mg of voriconazole and after ketoconazole 800 mg were all <10 msec. Females exhibited a greater increase in QTc than males, although all mean changes were <10 msec. Age was not found to affect the magnitude of increase in QTc.
No subject in any group had an increase in QTc of ≥60 msec from baseline. No subject experienced an interval exceeding the potentially clinically relevant threshold of 500 msec. However, the QT effect of voriconazole combined with drugs known to prolong the QT interval is unknown [see Contraindications (4) and Drug Interactions (7) ] .
12.3Pharmacokinetics The pharmacokinetics of voriconazole have been characterized in healthy subjects, special populations and patients. The pharmacokinetics of voriconazole are non-linear due to saturation of its metabolism. The interindividual variability of voriconazole pharmacokinetics is high.
Greater than proportional increase in exposure is observed with increasing dose. It is estimated that, on average, increasing the oral dose from 200 mg every 12 hours to 300 mg every 12 hours leads to an approximately 2.5-fold increase in exposure (AUC τ ); similarly, increasing the intravenous dose from 3 mg/kg every 12 hours to 4 mg/kg every 12 hours produces an approximately 2.5-fold increase in exposure (Table 12).
