Itraconazole-ratiopharm oral solution is indicated:
- For the treatment of oral and/or oesophageal candidosis in HIV-positive or other immunocompromised patients.
- As prophylaxis of deep fungal infections anticipated to be susceptible to Itraconazole-ratiopharm, when standard therapy is considered inappropriate, in patients with haematological malignancy or undergoing bone marrow transplant, and who are expected to become neutropenic (i.e. < 500 cells/µl). At present there are insufficient clinical efficacy data in the prevention of aspergillosis.
Itraconazole-ratiopharm oral solution is indicated for use in adults.
Consideration should be given to national and/or local guidance regarding the appropriate use of antifungal agents.
For optimal absorption, Itraconazole-ratiopharm oral solution should be taken without food (patients are advised to refrain from eating for at least 1 hour after intake).
A graduated measuring cup is provided to measure out the correct dose.
For the treatment of oral and/or oesophageal candidosis, the liquid should be swished around the oral cavity (approx. 20 seconds) and swallowed. There should be no rinsing after swallowing.
Treatment of oral and/or oesophageal candidosis: 200 mg (20 ml) per day in two intakes, or alternatively in one intake, for 1 week. If there is no response after 1 week, treatment should be continued for another week.
Treatment of fluconazole resistant oral and/or oesophageal candidosis: 100 to 200 mg (10-20 ml) twice daily for 2 weeks. If there is no response after 2 weeks, treatment should be continued for another 2 weeks. The 400mg daily dose should not be used for longer than 14 days if there are no signs of improvement.
Prophylaxis of fungal infections: 5 mg/kg per day administered in two intakes. In clinical trials, prophylaxis treatment was started immediately prior to the cytostatic treatment and generally one week before transplant procedure. Almost all proven deep fungal infections occurred in patients reaching neutrophil counts below 100 cells/µl. Treatment was continued until recovery of neutrophils (i.e. > 1000 cells/µl).
Pharmacokinetic parameters from clinical studies in neutropenic patients demonstrate considerable intersubject variation. Blood level monitoring should be considered particularly in the presence of gastrointestinal damage, diarrhoea and during prolonged courses of Itraconazole-ratiopharm oral solution.
Use in children
Since clinical data on the use of Itraconazole-ratiopharm oral solution in paediatric patients is limited, its use in children is not recommended unless the potential benefit outweighs the potential risks.
Prophylaxis of fungal infections: there are no efficacy data available in neutropenic children. Limited safety experience is available with a dose of 5 mg/kg per day administered in two intakes.
Use in elderly
Since clinical data on the use of Itraconazole-ratiopharm oral solution in elderly patients is limited, it is advised to use Itraconazole-ratiopharm oral solution in these patients only if the potential benefit outweighs the potential risks.
Use in patients with hepatic impairment
Limited data are available on the use of oral Itraconazole-ratiopharm in patients with hepatic impairment. Caution should be exercised when this drug is administered in this patient population. (See 5.2 Pharmacokinetic properties, Special populations, Hepatic impairment)
Use in patients with renal impairment
Limited data are available on the use of oral Itraconazole-ratiopharm in patients with renal impairment. Caution should be exercised when this drug is administered in this patient population.
Itraconazole-ratiopharm oral solution is contraindicated in patients with a known hypersensitivity to Itraconazole-ratiopharm or to any of the excipients.
Co-administration of the following drugs is contraindicated with Itraconazole-ratiopharm oral solution (see also 4.5 Interaction with other medicinal products and other forms of interaction):
- CYP3A4 metabolised substrates that can prolong the QT-interval e.g., astemizole, bepridil, cisapride, dofetilide, levacetylmethadol (levomethadyl), mizolastine, pimozide, quinidine, sertindole and terfenadine are contraindicated with Itraconazole-ratiopharm oral solution.).
Cross-hypersensitivity
There is no information regarding cross hypersensitivity between Itraconazole-ratiopharm and other azole antifungal agents. Caution should be used in prescribing Itraconazole-ratiopharm Oral Solution to patients with hypersensitivity to other azoles.
Cardiac effects
In a healthy volunteer study with Itraconazole-ratiopharm IV, a transient asymptomatic decrease of the left ventricular ejection fraction was observed.
Itraconazole-ratiopharm has been shown to have a negative inotropic effect and has been associated with reports of congestive heart failure. Interaction with other medicinal products).
Hepatic effects
Very rare cases of serious hepatotoxicity, including some cases of fatal acute liver failure, have occurred with the use of Itraconazole-ratiopharm. Some of these cases involved patients with no pre-existing liver disease. Some of these cases have been observed within the first month of treatment, including some within the first week. Liver function monitoring should be considered in patients receiving Itraconazole-ratiopharm treatment. Patients should be instructed to promptly report to their physician signs and symptoms suggestive of hepatitis such as anorexia, nausea, vomiting, fatigue, abdominal pain or dark urine. In these patients treatment should be stopped immediately and liver function testing should be conducted. Most cases of serious hepatotoxicity involved patients who had pre-existing liver disease, were treated for systemic indications, had significant other medical conditions and/or were taking other hepatotoxic drugs. In patients with raised liver enzymes or active liver disease, or who have experienced liver toxicity with other drugs, treatment should not be started unless the expected benefit exceeds the risk of hepatic injury. In patients with impaired hepatic function liver enzyme should be carefully monitored when taking Itraconazole-ratiopharm.
Use in children
Since clinical data on the use of Itraconazole-ratiopharm oral solution in paediatric patients is limited, its use in children is not recommended unless the potential benefit outweighs the potential risks.
Use in elderly
Since clinical data on the use of Itraconazole-ratiopharm oral solution in elderly patients is limited, it is advised to use Itraconazole-ratiopharm oral solution in these patients only if the potential benefit outweighs the potential risks.
Hepatic impairment
Limited data are available on the use of oral Itraconazole-ratiopharm in patients with hepatic impairment. Caution should be exercised when the drug is administered in this patient population. (See 5.2 Pharmacokinetic properties, Special populations, Hepatic impairment)
Renal impairment
Limited data are available on the use of oral Itraconazole-ratiopharm in patients with renal impairment. Caution should be exercised when this drug is administered in this patient population.
Prophylaxis in neutropenic patients
In clinical trials diarrhoea was the most frequent adverse event. This disturbance of the gastrointestinal tract may result in impaired absorption and may alter the microbiological flora potentially favouring fungal colonisation. Consideration should be given to discontinuing Itraconazole-ratiopharm oral solution in these circumstances.
Treatment of severely neutropenic patients
Itraconazole-ratiopharm oral solution as treatment for oral and/or esophageal candidosis was not investigated in severely neutropenic patients. Due to the pharmacokinetic properties (See 5.2 Pharmacokinetic properties), Itraconazole-ratiopharm oral solution is not recommended for initiation of treatment in patients at immediate risk of systemic candidosis.
Hearing Loss
Transient or permanent hearing loss has been reported in patients receiving treatment with Itraconazole-ratiopharm. Several of these reports included concurrent administration of quinidine which is contraindicated. The hearing loss usually resolves when treatment is stopped, but can persist in some patients.
Neuropathy
If neuropathy occurs that may be attributable to Itraconazole-ratiopharm oral solution, the treatment should be discontinued.
Cross-resistance
In systemic candidosis, if fluconazole-resistant strains of Candida species are suspected, it cannot be assumed that these are sensitive to Itraconazole-ratiopharm, hence their sensitivity should be tested before the start of Itraconazole-ratiopharm therapy
Interaction potential
Itraconazole-ratiopharm Oral Solution has a potential for clinically important drug interactions.
Itraconazole-ratiopharm should not be used within 2 weeks after discontinuation of treatment with CYP 3A4 inducing agents (rifampicin, rifabutin, phenobarbital, phenytoin, carbamazepine, Hypericum perforatum (St. John´s wort)). The use of Itraconazole-ratiopharm with these drugs may lead to subtherapeutic plasma levels of Itraconazole-ratiopharm and thus treatment failure.
Itraconazole-ratiopharm oral solution contains sorbitol. Patients with rare hereditary problems of fructose intolerance should not take this medicine. Also contains ethanol less than 100mg per dose.
No studies on the effects on the ability to drive and use machines have been performed.
When driving vehicles and operating machinery the possibility of adverse reactions such as dizziness, visual disturbances and hearing loss , which may occur in some instances, must be taken into account.
Approximately 9% of patients can be expected to experience adverse reactions while taking Itraconazole-ratiopharm. In patients receiving prolonged (approximately 1 month) continuous treatment especially, the incidence of adverse events has been higher (about 15%). The most frequently reported adverse experiences have been of gastrointestinal, hepatic and dermatological origin.

| Uncommon | Oedema Paediatric Population The safety of Itraconazole-ratiopharm oral solution was evaluated in 250 paediatric patients aged 6 months to 14 years who participated in five open-label clinical trials. These patients received at least one dose of Itraconazole-ratiopharm for prophylaxis of fungal infections or for treatment of oral thrush or systemic fungal infections and provided safety data. Based on pooled safety data from these clinical trials, the very common reported ADRs in paediatric patients were Vomiting (36.0%), Pyrexia (30.8%), Diarrhoea (28.4%), Mucosal inflammation (23.2%), Rash (22.8%), Abdominal pain (17.2%), Nausea (15.6%), Hypertension (14.0%), and Cough (11.2%). The nature of ADRs in paediatric patients is similar to that observed in adult subjects, but the incidence is higher in the paediatric patients.

more...Pharmacotherapeutic group: Antimycotic for systemic use, triazole derivative. ATC code: J02A C02 Mode of action Itraconazole-ratiopharm inhibits fungal 14α-demethylase, resulting in a depletion of ergosterol and disruption of membrane synthesis by fungi. PK/PD relationship The PK/PD relationship for Itraconazole-ratiopharm, and for triazoles in general, is poorly understood and is complicated by limited understanding of antifungal pharmacokinetics. Mechanism(s) of resistance Resistance of fungi to azoles appears to develop slowly and is often the result of several genetic mutations. Mechanisms that have been described are - Over-expression of ERG11, the gene that encodes 14-alpha-demethylase (the target enzyme) - Point mutations in ERG11 that lead to decreased affinity of 14-alpha-demethylase for Itraconazole-ratiopharm - Drug-transporter over-expression resulting in increased efflux of Itraconazole-ratiopharm from fungal cells (i.e., removal of Itraconazole-ratiopharm from its target) - Cross-resistance. Cross-resistance amongst members of the azole class of drugs has been observed within Candida species though resistance to one member of the class does not necessarily confer resistance to other azoles. Breakpoints Breakpoints for candida species are in preparation.
The prevalence of acquired resistance may vary geographically and with time for selected species, and local information on resistance is desirable, particularly when treating severe infections. As necessary, expert advice should be sought when the local prevalence of resistance is such that the utility of the agent in at least some types of infections is questionable. The in vitro susceptibility of fungi to Itraconazole-ratiopharm depends on the inoculum size, incubation temperature, growth phase of the fungi, and the culture medium used. For these reasons, the minimum inhibitory concentration of Itraconazole-ratiopharm may vary widely. Susceptibility in the table below is based on MIC90 < 1 mg Itraconazole-ratiopharm/L. There is no correlation between in vitro susceptibility and clinical efficacy.
1 These organisms may be encountered in patients who have returned from travel outside Europe. 2 Itraconazole-ratiopharm-resistant strains of Aspergillus fumigatus have been reported. 3 Natural intermediate susceptibility. Paediatric Population The tolerability and safety of Itraconazole-ratiopharm oral solution was studied in the prophylaxis of fungal infections in 103 neutropenic paediatric patients aged 0 to14 years (median 5 years) in an open-label uncontrolled phase III clinical study. Most patients (78%) were undergoing allogenic bone marrow transplantation for haematological malignancies. All patients received 5 mg/kg/day of Itraconazole-ratiopharm oral solution as a single or divided dose. Due to the design of the study, no formal conclusion with regard to efficacy could be derived. The most common adverse events considered definitely or possibly related to Itraconazole-ratiopharm were vomiting, abnormal liver function, and abdominal pain. Pharmacokinetic properties

In these patients treatment should be stopped immediately and liver function testing should be conducted. Most cases of serious hepatotoxicity involved patients who had pre-existing liver disease, were treated for systemic indications, had significant other medical conditions and/or were taking other hepatotoxic drugs. In patients with raised liver enzymes or active liver disease, or who have experienced liver toxicity with other drugs, treatment should not be started unless the expected benefit exceeds the risk of hepatic injury. In patients with impaired hepatic function liver enzyme should be carefully monitored when taking Itraconazole-ratiopharm. Use in children Since clinical data on the use of Itraconazole-ratiopharm oral solution in paediatric patients is limited, its use in children is not recommended unless the potential benefit outweighs the potential risks. Use in elderly Since clinical data on the use of Itraconazole-ratiopharm oral solution in elderly patients is limited, it is advised to use Itraconazole-ratiopharm oral solution in these patients only if the potential benefit outweighs the potential risks. Hepatic impairment Limited data are available on the use of oral Itraconazole-ratiopharm in patients with hepatic impairment. Caution should be exercised when the drug is administered in this patient population. (See 5.2 Pharmacokinetic properties, Special populations, Hepatic impairment) Renal impairment Limited data are available on the use of oral Itraconazole-ratiopharm in patients with renal impairment. Caution should be exercised when this drug is administered in this patient population. Prophylaxis in neutropenic patients In clinical trials diarrhoea was the most frequent adverse event. This disturbance of the gastrointestinal tract may result in impaired absorption and may alter the microbiological flora potentially favouring fungal colonisation. Consideration should be given to discontinuing Itraconazole-ratiopharm oral solution in these circumstances. Treatment of severely neutropenic patients Itraconazole-ratiopharm oral solution as treatment for oral and/or esophageal candidosis was not investigated in severely neutropenic patients. Due to the pharmacokinetic properties (See 5.2 Pharmacokinetic properties), Itraconazole-ratiopharm oral solution is not recommended for initiation of treatment in patients at immediate risk of systemic candidosis. Hearing Loss Transient or permanent hearing loss has been reported in patients receiving treatment with Itraconazole-ratiopharm. Several of these reports included concurrent administration of quinidine which is contraindicated. The hearing loss usually resolves when treatment is stopped, but can persist in some patients. Neuropathy If neuropathy occurs that may be attributable to Itraconazole-ratiopharm oral solution, the treatment should be discontinued. Cross-resistance In systemic candidosis, if fluconazole-resistant strains of Candida species are suspected, it cannot be assumed that these are sensitive to Itraconazole-ratiopharm, hence their sensitivity should be tested before the start of Itraconazole-ratiopharm therapy Interaction potential Itraconazole-ratiopharm Oral Solution has a potential for clinically important drug interactions. Itraconazole-ratiopharm should not be used within 2 weeks after discontinuation of treatment with CYP 3A4 inducing agents (rifampicin, rifabutin, phenobarbital, phenytoin, carbamazepine, Hypericum perforatum (St. John´s wort)). The use of Itraconazole-ratiopharm with these drugs may lead to subtherapeutic plasma levels of Itraconazole-ratiopharm and thus treatment failure. Itraconazole-ratiopharm oral solution contains sorbitol. Patients with rare hereditary problems of fructose intolerance should not take this medicine. Also contains ethanol less than 100mg per dose. 4.5 Interaction with other medicinal products and other forms of interaction4.5.1. Drugs affecting the metabolism of Itraconazole-ratiopharm: Itraconazole-ratiopharm is mainly metabolised through the cytochrome CYP3A4. Interaction studies have been performed with rifampicin, rifabutin and phenytoin, which are potent enzyme inducers of CYP3A4. Since the bioavailability of Itraconazole-ratiopharm and hydroxy-Itraconazole-ratiopharm was decreased in these studies to such an extent that efficacy may be largely reduced, the combination of Itraconazole-ratiopharm with these potent enzyme inducers is not recommended. No formal study data are available for other enzyme inducers, such as carbamazepine, Hypericum perforatum (St John's Wort), phenobarbital and isoniazid, but similar effects should be anticipated. Potent inhibitors of this enzyme such as ritonavir, indinavir, clarithromycin and erythromycin may increase the bioavailability of Itraconazole-ratiopharm. 4.5.2. Effect of Itraconazole-ratiopharm on the metabolism of other drugs: 4.5.2.1 Itraconazole-ratiopharm can inhibit the metabolism of drugs metabolised by the cytochrome 3A family. Pharmacokinetic Properties). This should be taken into account when the inhibitory effect of Itraconazole-ratiopharm on co-medicated drugs is considered. The following drugs are contraindicated with Itraconazole-ratiopharm: - Astemizole, bepridil, cisapride, dofetilide, levacetylmethadol (levomethadyl), mizolastine, pimozide, quinidine, sertindole and terfenadine are contraindicated with Itraconazole-ratiopharm oral solution since co-administration may result in increased plasma concentrations of these substrates, which can lead to QT prolongation and rare occurrences of torsade de pointes. - CYP3A4 metabolized HMG-CoA reductase inhibitors such as atorvastatin, lovastatin and simvastatin. - Triazolam and oral midazolam. - Ergot alkaloids such as dihydroergotamine, ergometrine (ergonovine), ergotamine and methylergometrine (methylergonovine). - Eletriptan - Nisoldipine Caution should be exercised when co-administering Itraconazole-ratiopharm with calcium channel blockers due to an increased risk of congestive heart failure. In addition to possible pharmacokinetic interactions involving the drug metabolising enzyme CYP3A4, calcium channel blockers can have negative inotropic effects which may be additive to those of Itraconazole-ratiopharm. The following drugs should be used with caution, and their plasma concentrations, effects or side effects should be monitored. Their dosage, if co-administered with Itraconazole-ratiopharm, should be reduced if necessary: - Oral anticoagulants; - HIV protease inhibitors such as ritonavir, indinavir, saquinavir; - Certain antineoplastic agents such as busulfan, docetaxel, trimetrexate and vinca alkaloids; - CYP3A4 metabolised calcium channel blockers such as dihydropyridines and verapamil; - Certain immunosuppressive agents: ciclosporin, tacrolimus, rapamycin (also known as sirolimus); - Certain glucocorticosteroids such as budesonide, dexamethasone, fluticasone and methylprednisolone; - Digoxin (via inhibition of P-glycoprotein) - Others: cilostazol, disopyramide, carbamazepine, buspirone, alfentanil, alprazolam, brotizolam, midazolam IV, rifabutin, ebastine, repaglinide, fentanyl, halofantrine, reboxetine and loperamide. The importance of the concentration increase and the clinical relevance of these changes during the co-administration with Itraconazole-ratiopharm remain to be established. 4.5.2.2 No interaction of Itraconazole-ratiopharm with zidovudine (AZT) and fluvastatin has been observed. No inducing effects of Itraconazole-ratiopharm on the metabolism of ethinyloestradiol and norethisterone were observed. 4.5.3. Effect on protein binding: In vitro studies have shown that there are no interactions on the plasma protein binding between Itraconazole-ratiopharm and imipramine, propranolol, diazepam, cimetidine, indometacin, tolbutamide and sulfamethazine. 4.6 Fertility, pregnancy and lactationPregnancy: Itraconazole-ratiopharm oral solution must not be used during pregnancy except for life-threatening cases where the potential benefit to the mother outweighs the potential harm to the foetus (see 4.3 Contraindications). In animal studies Itraconazole-ratiopharm has shown reproduction toxicity (see Pharmacotherapeutic group

Epidemiological data on exposure to Itraconazole-ratiopharm during the first trimester of pregnancy - mostly in patients receiving short-term treatment for vulvovaginal candidosis - did not show an increased risk for malformations as compared to control subjects not exposed to any known teratogens. Women of child-bearing potential: Women of childbearing potential taking Itraconazole-ratiopharm oral solution should use contraceptive precautions. Effective contraception should be continued until the next menstrual period following the end of Itraconazole-ratiopharm therapy. Fertility: In the rat, Itraconazole-ratiopharm had no effect on male or female fertility at doses which exhibited signs of general toxicity. The effect in humans is unknown. Lactation: A very small amount of Itraconazole-ratiopharm is excreted in human milk. Itraconazole-ratiopharm Oral Solution must not be used during lactation. 4.7 Effects on ability to drive and use machinesNo studies on the effects on the ability to drive and use machines have been performed. When driving vehicles and operating machinery the possibility of adverse reactions such as dizziness, visual disturbances and hearing loss , which may occur in some instances, must be taken into account. 4.8 Undesirable effectsApproximately 9% of patients can be expected to experience adverse reactions while taking Itraconazole-ratiopharm.
