En outre, la suspension buvable de posaconazole (200 mg ou 400 mg) a prolongé la valeur moyenne de la demi-vie terminale du midazolam passant de 3-4 heures à 8-10 heures approximativement pendant la co-administration. Am J Vet Res. GMR=Geometric least-squares mean ratio; CI=Confidence interval. Glipizide (10 mg single dose) had no clinically significant effect on posaconazole C max and AUC. 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. What are the possible side effects of posaconazole delayed-release tablets? The mean duration of therapy was comparable between the 2 treatment groups (80 days, posaconazole; 77 days, fluconazole). Posaconazole (Noxafil) is a broad-spectrum triazole antifungal for the treatment and prevention of fungal infections. have ever had an allergic reaction to other antifungal medicines such as ketoconazole, fluconazole, itraconazole, or voriconazole. Therefore, reserve azole antifungals, including posaconazole, for patients receiving a vinca alkaloid, including vincristine, who have no alternative antifungal treatment options. Pharmacokinetic modeling suggests that patients weighing greater than 120 kg may have lower posaconazole plasma drug exposure. Clipboard, Search History, and several other advanced features are temporarily unavailable. Following single-dose administration of 400 mg of the oral suspension, there was no significant effect of mild (eGFR: 50-80 mL/min/1.73 m2, n=6) or moderate (eGFR: 20-49 mL/min/1.73 m2, n=6) renal impairment on posaconazole pharmacokinetics; therefore, no dose adjustment is required in patients with mild to moderate renal impairment. Posaconazole is an azole antifungal agent available as concentrated solution to be diluted before intravenous administration, delayed-release tablet, or suspension for oral administration. No invasive fungal infections were observed over a median follow-up of 108 days post-transplantation. Increased plasma concentrations of digoxin have been reported in patients receiving digoxin and posaconazole. Would you like email updates of new search results? Increased plasma midazolam concentrations could potentiate and prolong hypnotic and sedative effects. Frequent monitoring of tacrolimus or cyclosporine whole blood trough concentrations should be performed during and at discontinuation of posaconazole treatment and the tacrolimus or cyclosporine dose adjusted accordingly. Download MS PowerPoint Slide. No related adverse reactions were noted by the investigator. The pharmacokinetics of this new solid oral tablet of posaconazole supports the clinical evaluation of once-daily dosing regimens for fungal infections. C(avg) values exceeded 1300 ng/mL. The following information was derived from data with posaconazole oral suspension or early tablet formulation. Privacy, Help It is, therefore, suggested to closely monitor for breakthrough fungal infections. A decrease in the QTc(F) interval (–3 msec) was also observed in a small number of subjects (n=16) administered placebo. Posaconazole as salvage treatment of invasive fusariosis in patients with underlying hematologic malignancy and other conditions. No healthy subject administered posaconazole had a QTc(F) interval ≥500 msec or an increase ≥60 msec in their QTc(F) interval from baseline. -, Raad II, Hachem RY, Herbrecht R, et al. Intravenous and delayed-release tablet posaconazole were 20 fold (p < 0.01) and sevenfold (p = 0.002) more likely than the oral suspension to achieve a therapeutic level. In this pooled analysis, the mean QTc (Fridericia) interval change from baseline was –5 msec following administration of the recommended clinical dose. The aim of this study was to evaluate rising single- and multiple-dose pharmacokinetics, safety and tolerability of the new tablet. High Resolution Image. increased amounts of midazolam in your blood. Bethesda, MD 20894, Copyright Phenytoin is also metabolized by CYP3A4. The following serious and otherwise important adverse reactions are discussed in detail in another section of the labeling: Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of posaconazole cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. 2021 Apr;87(4):465-474. doi: 10.1007/s00280-020-04179-w. Epub 2021 Jan 4. Of the circulating metabolites, the majority are glucuronide conjugates formed via UDP glucuronidation (phase 2 enzymes). Br J Clin Pharmacol. Available for Android and iOS devices. We comply with the HONcode standard for trustworthy health information. Posaconazole has been shown to be active against most isolates of the following microorganisms, both in vitro and in clinical infections [see Indications and Usage (1)]. During the clinical trials, some patients received posaconazole oral suspension up to 1600 mg/day with no adverse reactions noted that were different from the lower doses. This was a single-centre, randomized, placebo-controlled, Phase I, rising single- and multiple-dose study of healthy subjects aged 18-65 years who received a posaconazole tablet as 200 mg once daily, 200 mg twice daily or 400 mg once daily. These isolates also showed reduced susceptibility to other azoles, suggesting cross-resistance between azoles. Efficacy of prophylaxis was evaluated using a composite endpoint of proven/probable IFIs, death, or treatment with systemic antifungal therapy (patients may have met more than one of these criteria). Please enable it to take advantage of the complete set of features! Bhatnagar S, Mukherjee D, Salem AH, Miles D, Menon RM, Gibbs JP. 2020 Dec 1;75(12):3682-3687. doi: 10.1093/jac/dkaa377. Electrolyte disturbances, especially those involving potassium, magnesium or calcium levels, should be monitored and corrected as necessary before and during posaconazole therapy. Maintenance dose: 300 mg IV once a day, starting on the second day. Kersemaekers WM, Dogterom P, Xu J, Marcantonio EE, de Greef R, Waskin H, van Iersel ML. The clinical significance of this finding is not known. The following information includes only the average doses of this medicine. The easiest way to lookup drug information, identify pills, check interactions and set up your own personal medication records. The pharmacokinetics of posaconazole modified release tablets are 2007;356:348–59. Steady-state plasma concentrations are attained by Day 6 at the 300 mg dose (QD after BID loading dose at Day 1). Patients were enrolled in a non-comparative pharmacokinetic and safety trial of posaconazole delayed-release tablets when given as antifungal prophylaxis (Delayed-Release Tablet Study 1). Instruct patients that if they miss a dose, they should take it as soon as they remember. These doses are equivalent to 3.9- or 3.5-times the exposure achieved with a 400-mg BID oral suspension regimen, respectively, based on steady-state AUC in healthy volunteers administered a high-fat meal (400-mg BID oral suspension regimen). Gastro-resistant means that the tablets pass through the stomach without being broken down until they reach the intestine. [see Drug Interactions (7.1) and Clinical Pharmacology (12.3)], Posaconazole delayed-release tablet (300 mg), General Disorders and Administration Site Conditions, Respiratory, Thoracic and Mediastinal Disorders, [see Contraindications (4.3) and Warnings and Precautions (5.2)], Effect on Bioavailability of Posaconazole, Drug Interactions (7.1) including recommendations], Effect on Bioavailability of Coadministered. Following administration of posaconazole oral suspension, posaconazole is predominantly eliminated in the feces (71% of the radiolabeled dose up to 120 hours) with the major component eliminated as parent drug (66% of the radiolabeled dose). Noxafil delayed-release tablets exhibit dose proportional pharmacokinetics after single and multiple dosing up to 300 mg. Cyclosporine: Posaconazole has been shown to increase cyclosporine whole blood concentrations in heart transplant patients upon initiation of posaconazole treatment. Ritonavir and Atazanavir: Ritonavir and atazanavir are metabolized by CYP3A4 and posaconazole increases plasma concentrations of these drugs [see Clinical Pharmacology (12.3)]. The recommended dose is 300 mg twice a day on the first day followed by 300 mg once a day thereafter; … Sirolimus: Concomitant administration of posaconazole with sirolimus increases the sirolimus blood concentrations by approximately 9-fold and can result in sirolimus toxicity. Posaconazole may increase the plasma concentrations of ergot alkaloids (ergotamine and dihydroergotamine) which may lead to ergotism. Conclusions: Concomitant administration of posaconazole with midazolam increases the midazolam plasma concentrations by approximately 5-fold. When given orally in healthy volunteers, posaconazole delayed-release tablets are absorbed with a median Tmax of 4 to 5 hours. The mean apparent oral clearance (CL/F) was reduced by 18%, 36%, and 28% in subjects with mild, moderate, or severe hepatic impairment, respectively, compared to subjects with normal hepatic function. There are no studies demonstrating the appropriate dose in lung transplant recipients (LTR). Posaconazole delayed-release tablets are eliminated with a mean half-life (t½) ranging between 26 to 31 hours. Posaconazole: an extended-spectrum triazole antifungal agent. No malformations were seen in rabbits dosed during organogenesis (Gestational Days 7 through 19) at doses up to 80 mg/kg (5 times the exposure achieved with the 400 mg twice daily oral suspension regimen). Posaconazole Accord contains the active substance posaconazole and is a ... Posaconazole Accord is available as gastro-resistant tablets (100 mg). Swallow tablets whole. Phenytoin induces UDP-glucuronidase and decreases posaconazole plasma concentrations. This Patient Information has been approved by the U.S. Food and Drug Administration.

The excreted metabolites in urine and feces account for ~17% of the administered radiolabeled dose. Li H, Wei Y, Zhang S, Xu L, Jiang J, Qiu Y, Mangin E, Zhao XM, Xie S. Clin Drug Investig. Objectives: Rifabutin induces UDP-glucuronidase and decreases posaconazole plasma concentrations. Before you take posaconazole delayed-release tablets, tell your healthcare provider if you: Tell your healthcare provider about all the medicines you take. The 24 subjects were studied in two cohorts of 12 subjects each (9 active and 3 placebo). Concomitant use of posaconazole and phenytoin should be avoided unless the benefit to the patient outweighs the risk. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency. have liver disease or develop itching, nausea or vomiting, their eyes or skin turn yellow, they feel more tired than usual or feel like they have the flu. A summary of the drugs studied clinically, for which plasma concentrations were affected by posaconazole, is provided in Table 23 [see Contraindications (4) and Drug Interactions (7.1) including recommendations]. Patients who have severe diarrhea or vomiting should be monitored closely for breakthrough fungal infections when receiving posaconazole delayed-release tablets. This study assessed patients while on treatment plus 7 days and 100 days postrandomization. Follow your doctor's orders or the directions on the label. Effect of a high-fat meal on the pharmacokinetics of 300-milligram posaconazole in a solid oral tablet formulation. Posaconazole delayed-release tablets should be used only for the prophylaxis indication. What is posaconazole delayed-release tablets? Most of the vinca alkaloids (e.g., vincristine and vinblastine) are substrates of CYP3A4. notice a change in heart rate or heart rhythm, or have a heart condition or circulatory disease. This site needs JavaScript to work properly. Coadministration with the HMG-CoA reductase inhibitors that are primarily metabolized through CYP3A4 (e.g., atorvastatin, lovastatin, and simvastatin) is contraindicated since increased plasma concentration of these drugs can lead to rhabdomyolysis [see Drug Interactions (7.3) and Clinical Pharmacology (12.3)]. DOSAGE AND ADMINISTRATION -----­ Indication Dose and Duration of Therapy Prophylaxis of Injection*: invasive Aspergillus Loading dose: 300 mg Noxafil injection Candida intravenously twice a day on the first day. Posaconazole had no effect on fertility of male rats at a dose up to 180 mg/kg (1.7 x the 400-mg BID oral suspension regimen based on steady-state plasma concentrations in healthy volunteers) or female rats at a dose up to 45 mg/kg (2.2 x the 400-mg BID oral suspension regimen). Therefore, coadministration of phenytoin with posaconazole increases phenytoin plasma concentrations [see Clinical Pharmacology (12.3)]. 2020 Dec;27(1):110-127. doi: 10.1080/10717544.2019.1704940. Some azoles, including posaconazole, have been associated with prolongation of the QT interval on the electrocardiogram. QD, once daily. No dosage adjustment of posaconazole delayed-release tablets is required when given concomitantly with metoclopramide. Posaconazole is primarily metabolized via UDP glucuronosyltransferase and is a substrate of p glycoprotein (P-gp) efflux. Do not divide, crush, or chew. Maintenance dose: 300 mg (three 100 mg … The mean duration of therapy was comparable between the 2 treatment groups (29 days, posaconazole; 25 days, fluconazole or itraconazole). Loading dose 200 mg on first day, then 100 mg once daily for 13 days, dose to be taken with food. Posaconazole delayed-release tablets may cause serious side effects, including: drug interactions with cyclosporine or tacrolimus. As anticipated, posaconazole tablets resulted in higher trough concentrations at all assessment points. This needs to be considered when switching a patient from one oral formulation to another, for example, switching from tablets or capsules to a liquid to aid administration in a patient with dysphagia or swallowing difficulties. Additional clinical studies demonstrated that no clinically significant effects on zidovudine, lamivudine, indinavir, or caffeine were observed when administered with posaconazole 200 mg QD; therefore, no dose adjustments are required for these coadministered drugs when coadministered with posaconazole 200 mg QD. Concomitant administration of posaconazole delayed-release tablets with drugs affecting gastric pH or gastric motility did not demonstrate any significant effects on posaconazole pharmacokinetic exposure (see Table 18). Clin Infect Dis. There is no experience with overdosage of posaconazole delayed-release tablets. As in Oral Suspension Study 1, efficacy of prophylaxis was evaluated using a composite endpoint of proven/probable IFIs, death, or treatment with systemic antifungal therapy (Patients might have met more than one of these criteria). are currently taking drugs that are known to prolong the QTc interval and are metabolized through CYP3A4. Cornely OA, Maertens J, Winston DJ, et al. Posaconazole tablets are absorbed with a median T max of 4 to 5 hours and exhibits dose proportional pharmacokinetics after single and multiple dosing up to 300 mg. Concomitant administration of posaconazole with the CYP3A4 substrates, pimozide and quinidine may result in increased plasma concentrations of these drugs, leading to QTc prolongation and cases of torsades de pointes [see Warnings and Precautions (5.2) and Drug Interactions (7.2)]. Due to the variability in exposure with Posaconazole delayed-release tablets, patients with severe renal impairment should be monitored closely for breakthrough fungal infections [see Dosage and Administration (2.6) and Use in Specific Populations (8.6)]. Posaconazole delayed-release tablets are indicated for prophylaxis of invasive Aspergillus and Candida infections in patients who are at high risk of developing these infections due to being severely immunocompromised, such as hematopoietic stem cell transplant (HSCT) recipients with graft-versus-host disease (GVHD) or those with hematologic malignancies with prolonged neutropenia from chemotherapy. Last updated on Feb 1, 2021. During the clinical trials, some patients received posaconazole oral suspension up to Diarrhoea and proton pump inhibitors were also associated with reduced suspension bioavailability. Due to the variability in exposure, patients with severe renal impairment should be monitored closely for breakthrough fungal infections [see Dosage and Administration (2)]. Results: Patients who develop abnormal liver function tests during posaconazole therapy should be monitored for the development of more severe hepatic injury. Posaconazole is primarily metabolized via UDP glucuronidation (phase 2 enzymes) and is a substrate for p-glycoprotein (P-gp) efflux. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for posaconazole and any potential adverse effects on the breastfed child from posaconazole or from the underlying maternal condition. Oral suspension: 200 mg orally three times a day. Posaconazole is an azole antifungal agent [see Clinical Pharmacology (12.4)]. Therefore, plasma concentrations of drugs predominantly metabolized by CYP3A4 may be increased by posaconazole [see Clinical Pharmacology (12.3)]. No difference in the incidence of brain ventricle enlargement between control and treated animals was observed following the subsequent 5 month treatment-free period. Keep posaconazole delayed-release tablets and all medicines out of the reach of children. 2015 May;76(5):454-9.doi: 10.2460/ajvr.76.5.454. Liver function tests should be evaluated at the start of and during the course of posaconazole therapy. * Patients may have met more than one criterion defining failure. 150 mg (morning dose of 150 mg Ranitidine BID), 15 mg four times daily during 2 days (Day -1 and 1), 400 mg (oral suspension) BID × 10 and 20 days, 200 mg QD on the 1st day, 200 mg BID on the 2nd day, then 400 mg BID x 8 Days, Stable maintenance dose in heart transplant recipients, ↑ cyclosporine whole blood trough concentrations. Mycoses. Posaconazole tablets are the preferred formulation to optimize plasma concentrations and generally provide higher plasma drug exposures than posaconazole oral suspension. Males were more likely to achieve a therapeutic level. Posaconazole delayed-release tablets, posaconazole injection, and posaconazole oral suspension are prescription medicines used to help prevent and treat fungal infections that can spread throughout your body (invasive fungal infections). Recommended dose is shown in Table 1. Therefore, no adjustment is necessary for oral dosing in patients with mild to severe renal impairment. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. Posaconazole (POS) trough concentrations (mean ± SD) following once-daily multiple oral administration of posaconazole tablets (200 or 400 mg). Frequent monitoring of tacrolimus whole blood trough concentrations should be performed during and at discontinuation of posaconazole treatment and the tacrolimus dose adjusted accordingly [see Warnings and Precautions (5.1) and Clinical Pharmacology (12.3)]. Unable to load your collection due to an error, Unable to load your delegates due to an error. Twenty patients received 200 mg daily dose and 210 patients received 300 mg daily dose (following twice daily dosing on Day 1 in each cohort). Tablet: 300 mg PO BID on Day 1, then 300 mg PO qDay. A summary of drugs studied clinically with the oral suspension or an early tablet formulation, which affect posaconazole concentrations, is provided in Table 22. The safety of posaconazole delayed-release tablets has been assessed in 230 patients in clinical trials. No clinically relevant effects on the pharmacokinetics of posaconazole were observed when posaconazole delayed-release tablets are concomitantly used with antacids, H2-receptor antagonists and proton pump inhibitors [see Clinical Pharmacology (12.3)]. Clin Infect Dis. Concomitant use of posaconazole and rifabutin should be avoided unless the benefit to the patient outweighs the risk. Advise patients that posaconazole delayed-release tablets must be swallowed whole and not divided, crushed, or chewed. The oral liquid and tablet forms of posaconazole are not equivalent and may not have the same dose or schedule. 2007;356:335–47. In animal reproduction studies, skeletal malformations (cranial malformations and missing ribs) and maternal toxicity (reduced food consumption and reduced body weight gain) were observed when posaconazole was dosed orally to pregnant rats during organogenesis at doses ≥1.4 times the 400 mg twice daily oral suspension regimen based on steady-state plasma concentrations of posaconazole in healthy volunteers. Subscribe to Drugs.com newsletters for the latest medication news, new drug approvals, alerts and updates. Clinical isolates of Candida albicans and Candida glabrata with decreased susceptibility to posaconazole were observed in oral swish samples taken during prophylaxis with posaconazole and fluconazole, suggesting a potential for development of resistance. Therefore, monitoring of digoxin plasma concentrations is recommended during coadministration. A lower Cavg may be associated with an increased risk of treatment failure, defined as treatment discontinuation, use of empiric systemic antifungal therapy (SAF), or occurrence of breakthrough invasive fungal infections. It is recommended to avoid concomitant use of efavirenz with posaconazole unless the benefit outweighs the risks. 2007;44:2–12. Posaconazole does not have any major circulating oxidative (CYP450 mediated) metabolites. The posaconazole delayed-release oral tablet is not significantly affected by gastric acid suppression therapy, and the intravenous dosage form provides an option for patients who are intubated or unable to tolerate oral medications. Posaconazole is not removed by hemodialysis. The posaconazole suspension is indicated to be administered as 200 mg three times daily (TID) for prophylaxis or as 400 mg twice daily (BID), or 200 mg four times daily (QID) for treatment of refractory IFDs or for treatment of patients with IFD who are intolerant to first-line therapy. If concomitant administration is required, close monitoring for breakthrough fungal infections is recommended [see Clinical Pharmacology (12.3)]. If your dose is different, do not change it unless your doctor tells you to do so. A total of 12 patients 13 to 17 years of age received 600 mg/day (200 mg three times a day) of posaconazole oral suspension for prophylaxis of invasive fungal infections. Posaconazole may increase the plasma concentrations of ergot alkaloids (ergotamine and dihydroergotamine) which may lead to ergotism [see Drug Interactions (7.4)]. The accumulation ratio upon multiple doses over 8 days was ∼3 for 200 and 400 mg once daily and ∼5 for 200 mg twice daily. The first study (Oral Suspension Study 1) was a randomized, double-blind trial that compared posaconazole oral suspension (200 mg three times a day) with fluconazole capsules (400 mg once daily) as prophylaxis against invasive fungal infections in allogeneic hematopoietic stem cell transplant (HSCT) recipients with Graft versus Host Disease (GVHD). Single-dose phase I study to evaluate the pharmacokinetics of posaconazole in new tablet and capsule formulations relative to oral suspension. In subjects with severe renal impairment (eGFR: <20 mL/min/1.73 m2), the mean plasma exposure (AUC) was similar to that in patients with normal renal function (eGFR: >80 mL/min/1.73 m2); however, the range of the AUC estimates was highly variable (CV=96%) in these subjects with severe renal impairment as compared to that in the other renal impairment groups (CV<40%). A clinical study in healthy volunteers also indicates that posaconazole is a strong CYP3A4 inhibitor as evidenced by a >5-fold increase in midazolam AUC. -Maintenance dose: 300 mg orally once a day, starting on the second day. Patients must be monitored closely for adverse effects associated with high plasma concentrations of midazolam and benzodiazepine receptor antagonists must be available to reverse these effects [see Drug Interactions (7.5) and Clinical Pharmacology (12.3)]. Dosage: Table 4: Dosage for Posaconazole Delayed-Release Tablets ; Indication: Dose and Duration of Therapy : Prophylaxis of invasive Aspergillus and Candida infections: Loading dose: 300 mg (three 100 mg delayed-release tablets) twice a day on the first day. Data sources include IBM Watson Micromedex (updated 3 May 2021), Cerner Multum™ (updated 4 May 2021), ASHP (updated 3 May 2021) and others. Dose reduction of calcium channel blockers may be needed. The safety and effectiveness of posaconazole in pediatric patients below the age of 13 years (birth to 12 years) have not been established. If such drugs are necessary, patients should be monitored closely for breakthrough fungal infections. It is recommended that no dose adjustment of posaconazole is needed in patients with mild to severe hepatic impairment (Child-Pugh Class A, B, or C) [see Dosage and Administration (2) and Warnings and Precautions (5.4)]. Patients must be monitored closely for adverse effects associated with high plasma concentrations of benzodiazepines metabolized by CYP3A4 and benzodiazepine receptor antagonists must be available to reverse these effects [see Warnings and Precautions (5.6) and Clinical Pharmacology (12.3)]. It is recommended to reduce cyclosporine dose to approximately three-fourths of the original dose upon initiation of posaconazole treatment. Posaconazole therapy was given for a median duration of 28 days. Posaconazole may increase the plasma concentrations of calcium channel blockers metabolized by CYP3A4 (e.g., verapamil, diltiazem, nifedipine, nicardipine, felodipine). Posaconazole exposure increased in a dose-related manner. The mean volume of distribution of posaconazole after intravenous solution administration was 261 L and ranged from 226-295 L between studies and dose levels. This patient population was 62% male, had a mean age of 51 years (range 19-78 years, 17% of patients were ≥65 years of age), and were 93% white and 16% Hispanic. A lower-than-recommended posaconazole tablet dose achieved therapeutic levels in most patients and was better tolerated. The recommended oral dosage is 300 mg once a day with the tablets (after a loading dose of 300 mg twice daily on day 1) and 200 mg three to four times a day (600 to 800 mg daily) with the oral suspension. Therefore, coadministration of rifabutin with posaconazole increases rifabutin plasma concentrations [see Clinical Pharmacology (12.3)]. For a small number of medicines, there are differences in equivalent doses of oral formulations of the same medicine. In addition, cases of torsades de pointes have been reported in patients taking posaconazole. High-dose posaconazole for azole-resistant aspergillosis and other difficult-to-treat mould infections. Pharmacotherapy. The Cmax and AUC of posaconazole following administration of posaconazole delayed-release tablets is increased 16% and 51%, respectively, when given with a high fat meal compared to a fasted state (see Table 17). There are no data on the presence of posaconazole in human milk, the effects on the breastfed infant, or the effects on milk production. Exposure Response Relationship: In clinical studies of neutropenic patients who were receiving cytotoxic chemotherapy for acute myelogenous leukemia (AML) or myelodysplastic syndromes (MDS) or hematopoietic stem cell transplant (HSCT) recipients with Graft versus Host Disease (GVHD), a wide range of plasma exposures to posaconazole was noted following administration of posaconazole oral suspension. 2015 Feb;35(2):208-19. doi: 10.1002/phar.1533. Frequent monitoring of cyclosporine whole blood trough concentrations should be performed during and at discontinuation of posaconazole treatment and the cyclosporine dose adjusted accordingly [see Warnings and Precautions (5.1) and Clinical Pharmacology (12.3)]. -, Ullmann AJ, Lipton JH, Vesole DH, et al. Compared to subjects with normal hepatic function, the mean Cmax was 1% higher, 40% higher, and 34% lower in subjects with mild, moderate, or severe hepatic impairment, respectively. Posaconazole is highly bound to human plasma proteins (>98%), predominantly to albumin. In the rabbit, the no-effect dose was 20 mg/kg, while high doses of 40 mg/kg and 80 mg/kg (3 or 5 times the clinical exposure) caused an increase in resorptions. Most of the ergot alkaloids are substrates of CYP3A4. Subsequent levels were more likely to be therapeutic after dose adjustments (OR 3.31; 95% CI 1.3–8.6; p = 0.02), regardless of timing of initial non-therapeutic level.
