For a full list of excipients, see section 6.1.



3. Pharmaceutical Form



Oral gel.



White gel with orange taste.



4. Clinical Particulars



4.1 Therapeutic Indications



Oral treatment and prevention of fungal infections of the oropharynx and of superinfections due to Gram-positive bacteria.



4.2 Posology And Method Of Administration



For oral administration



For topical treatment of the oropharynx



Treatment should be continued for up to 2 days after the symptoms have cleared.



Adult, Elderly and Children aged 6 years and over



Apply a small amount of gel directly to the affected area with a clean finger four times a day. The gel should be kept in the mouth for as long as possible.



For oral candidosis, dental prostheses should be removed at night and brushed with the gel.



Children aged 4 months – 6 years:



Apply a small amount of gel directly to the affected area with a clean finger twice daily. The gel should be kept in the mouth for as long as possible.



The lower age limit should be increased by 1-2 months for infants who are pre-term, or infants exhibiting slow neuromuscular development.



4.3 Contraindications



Known hypersensitivity to miconazole or to any of the excipients.



In infants less than 4 months of age or in those whose swallowing reflex is not yet sufficiently developed.



In patients with liver dysfunction.



Coadministration of the following drugs that are subject to metabolism by CYP3A4: (See Section 4.5 Interactions with Other Medicinal Products and Other Forms of Interaction)



- Substrates known to prolong the QT-interval e.g., astemizole, cisapride, dofetilide, mizolastine, pimozide, quinidine, sertindole and terfenadine



- Ergot alkaloids



- HMG-CoA reductase inhibitors such as simvastatin and lovastatin



- Triazolam and oral midazolam



4.4 Special Warnings And Precautions For Use



If the concomitant use of Daktarin and oral anticoagulants such as warfarin is envisaged, the anticoagulant effect should be carefully monitored and titrated (see section 4.5).



It is advisable to monitor miconazole and phenytoin levels, if these two drugs are used concomitantly.



In patients using certain oral hypoglycaemics such as sulphonylureas, an enhanced therapeutic effect leading to hypoglycaemia may occur during concomitant treatment with miconazole and appropriate measures should be considered (See Section 4.5 Interactions with Other Medicinal Products and Other Forms of Interaction).



Particularly in infants and young children, caution is required to ensure that the gel does not obstruct the throat. Hence, the gel should not be applied to the back of the throat and each dose should be divided into smaller portions. Observe the patient for possible choking.



The lower age limit should be increased by 1-2 months for infants who are pre-term, or infants exhibiting slow neuromuscular development.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



When using any concomitant medication the corresponding label should be consulted for information on the route of metabolism. Miconazole can inhibit the metabolism of drugs metabolised by the CYP3A4 and CYP2C9 enzyme systems. This can result in an increase and/or prolongation of their effects, including adverse effects.



Oral miconazole is contraindicated with the coadministration of the following drugs that are subject to metabolism by CYP3A4 (See Section 4.3 Contraindications);



- Substrates known to prolong the QT-interval e.g., astemizole, cisapride, dofetilide, mizolastine, pimozide, quinidine, sertindole and terfenadine



- Ergot alkaloids



- HMG-CoA reductase inhibitors such as simvastatin and lovastatin



- Triazolam and oral midazolam



When coadministered with oral miconazole the following drugs should be used with caution because of a possible increase or prolongation of the therapeutic outcome and/or adverse events. If necessary, their dosage should be reduced and, where appropriate, plasma levels monitored:



Drugs subject to metabolism by CYP2C9 (see Section 4.4 Special Warnings and Precautions for Use);



- Oral anticoagulants such as warfarin,



- Oral hypoglycaemics such as sulphonylureas



- Phenytoin



Other drugs subject to metabolism by CYP3A4;



- HIV Protease Inhibitors such as saquinavir;



- Certain antineoplastic agents such as vinca alkaloids, busulfan and docetaxel;



- Certain calcium channel blockers such as dihydropyridines and verapamil;



- Certain immunosuppressive agents: cyclosporin, tacrolimus, sirolimus (= rapamycin)



- Others: carbamazepine, cilostasol, disopyramide, buspirone, alfentanil, sildenafil, alprazolam, brotizolam, midazolam IV, rifabutin, methylprednisolone, trimetrexate, ebastine and reboxetine.



4.6 Pregnancy And Lactation



In animals, miconazole has shown no teratogenic effects but is foetotoxic at high oral doses. The significance of this to man is unknown. However, as with other imidazoles, Daktarin Sugar Free 2% Oral Gel should be avoided in pregnant women if possible. The potential hazards should be balanced against the possible benefits.



It is not known whether miconazole is excreted in human milk. Caution should be exercised when prescribing Daktarin Sugar Free 2% Oral Gel to nursing mothers.



4.7 Effects On Ability To Drive And Use Machines



Daktarin should not affect alertness or driving ability.



4.8 Undesirable Effects



The safety of DAKTARIN Sugar free 2% Oral Gel was evaluated in 111 patients with oral candidiasis or oral mycoses who participated in 5 clinical trials. Of these 111 patients, 88 were adults with oral candidiasis or oral mycoses who participated in 1 randomised, active



Based on the pooled safety data from these 5 clinical trials (adult and paediatric), the most commonly reported (



Table A includes all identified ADRs, including those that that have been reported from post-marketing experience.



The frequency categories use the following convention: very common (



Adult Patients



Based on the pooled safety data from the 4 clinical trials in adults, common ADRs reported included nausea (4.5%), product taste abnormal (4.5%), oral discomfort (3.4%), dry mouth (2.3%), dysgeusia (1.1%), and vomiting (1.1%).



Paediatric Patients



In the 1 paediatric clinical trial, the frequency of nausea (13.0%) and vomiting (13.0%) was very common, and regurgitation (8.7%) was common. As identified through post-marketing experience, choking may occur in infants and young children (See Section 4.3 Contraindications and Section 4.4 Special Warnings and Special Precautions). The frequency, type, and severity of other ADRs in children are expected to be similar to that in adults.

4.9 Overdose



Symptoms:



In the event of accidental overdose, vomiting and diarrhoea may occur.



Treatment:



Treatment is symptomatic and supportive. A specific antidote is not available.



In the event of accidental ingestion of large quantities of Daktarin an appropriate method of gastic emptying may be used, if considered necessary (See Section 4.5 Interactions with Other Medicinal Products and Other Forms of Interaction.)



5. Pharmacological Properties



5.1 Pharmacodynamic Properties



ATC Code: A01A B09 and A07A C01



Miconazole possesses an antifungal activity against the common dermatophytes and yeasts as well as an antibacterial activity against certain gram-positive bacilli and cocci.



Its activity is based on the inhibition of the ergosterol biosynthesis in fungi and the change in the composition of the lipid components in the membrane, resulting in fungal cell necrosis.



5.2 Pharmacokinetic Properties



Absorption:



Miconazole is systemically absorbed after administration as the oral gel. Administration of a 60 mg dose of miconazole as the oral gel results in peak plasma concentrations of 31 to 49 ng/mL, occurring approximately two hours post-dose.



Distribution:



Absorbed miconazole is bound to plasma proteins (88.2%), primarily to serum albumin and red blood cells (10.6%).



Metabolism and Elimination:



The absorbed portion of miconazole is largely metabolized; less than 1% of an administered dose is excreted unchanged in the urine. The terminal half-life of plasma miconazole is 20 to 25 hours in most patients. The elimination half-life of miconazole is similar in renally impaired patients. Plasma concentrations of miconazole are moderately reduced (approximately 50%) during hemodialysis. About 50% of an oral dose may be excreted in the faeces partly metabolized and partly unchanged.



5.3 Preclinical Safety Data



Preclinical data reveal no special hazard for humans based on conventional studies of local irritation, single and repeated dose toxicity, genotoxicity, and toxicity to reproduction.
