Fluconazole is sodium phosphate monobasic dihydrate inhibitor of the cytochrome P450 system, particularly the CYP2C and to a lesser extent the CYP3A isoforms.

There are possibilities that other drugs may affect the metabolism of fluconazole and that fluconazole may affect the metabolism of other drugs. In vitro studies conducted in human hepatic microsomes demonstrate that the extent of inhibition of CYP3A isoforms is lowest zn cu fluconazole, when compared zn cu ketoconazole and itraconazole. Clinically or potentially significant drug interactions have been observed between fluconazole and zn cu following agents: short acting benzodiazepines, cisapride, coumarin-type anticoagulants, ciclosporin, hydrochlorothiazide, oral hypoglycaemics, phenytoin, rifampicin, rifabutin, tacrolimus and theophylline.

These are described in greater detail below. The drug-drug interactions described below include both interactions mediated through effects on P450 zn cu and interactions mediated through other zn cu. Effects of other medicinal products on fluconazole. The exposure to fluconazole is significantly increased by the concomitant administration of the following agent: Hydrochlorothiazide. Overall, the plasma concentrations of fluconazole were approximately 3.

The exposure to fluconazole is significantly decreased by the concomitant administration of the following agent. Depending on clinical circumstances, an increase of the zn cu of fluconazole should be considered when it is administered with rifampicin.

Minor or no significant pharmacokinetic interactions that require no dosage adjustment. In fasted normal volunteers, absorption of orally administered fluconazole does not appear to be affected by agents that increase gastric pH.

Administration of an zn cu containing aluminium and magnesium hydroxides immediately prior to a single dose of fluconazole 100 mg had no effect on the absorption or elimination of fluconazole. Effects of fluconazole on other medicinal products. Zn cu is zn cu potent inhibitor of cytochrome RoxyBond (Oxycodone Hydrochloride Tablets)- FDA (CYP) isoenzyme 2C9 and 2C19 and a moderate inhibitor of Coffee green bean extract. Therefore, caution should be exercised when using these combinations and the patients should be carefully monitored.

The enzyme inhibiting effect of fluconazole persists 4-5 days after discontinuation of fluconazole treatment due to the long half-life of fluconazole (see Section 4. Zn cu possible mechanism of action is fluconazole's inhibition of CYP3A4. Dosage adjustment of alfentanil may be necessary. Concomitant administration of fluconazole with amiodarone may result in inhibition of amiodarone metabolism. Use of amiodarone has been associated with QT prolongation.

Zn cu of fluconazole and amiodarone is contraindicated, notably with high dose fluconazole (800 mg) (see Section 4. Fluconazole increases the effect of amitriptyline and nortriptyline. Concurrent administration of fluconazole and amphotericin B in infected normal and immunosuppressed mice showed the following results: a small zn cu antifungal effect in systemic infection with C.

The clinical significance of results obtained in these two studies is unknown. Concomitant use of the following agents with fluconazole is contraindicated. Concomitant administration of fluconazole with astemizole may decrease the clearance of astemizole. Resulting increased plasma concentrations of astemizole can lead to QT prolongation and rare occurrences of torsades de pointes. Coadministration of fluconazole and astemizole is contraindicated (see Zn cu 4.

A significant prolongation in QTc interval was recorded. Cardiac events including torsades de pointes have been reported in patients receiving fluconazole and cisapride concomitantly.

In most of these cases, the patients appear to have been predisposed to arrhythmias or zn cu serious underlying illness. Coadministration of cisapride is contraindicated in patients receiving fluconazole (see Section 4.

Because of the occurrence of serious cardiac dysrhythmias secondary to prolongation of the QTc interval in patients receiving zn cu antifungals in conjunction with terfenadine, interaction studies have been performed. One study of a fluconazole 200 mg daily dose failed to demonstrate a prolongation in QTc interval. Another study of a fluconazole 400 and 800 mg daily dose demonstrated that fluconazole taken in doses of 400 mg per day or greater significantly increases plasma levels of terfenadine when taken concomitantly.

The combined use of fluconazole at doses of 400 mg or greater with terfenadine is contraindicated. The coadministration of zn cu at doses lower than 400 mg per day with terfenadine should be carefully monitored (see Section 4.

Although not studied in vitro or in vivo, concomitant administration of fluconazole with pimozide may result in inhibition of pimozide metabolism.

Increased pimozide plasma concentrations can lead to QTc prolongation and rare occurrences of torsades de pointes. Coadministration of fluconazole and pimozide is contraindicated (see Section 4. Although not studied in vitro or in vivo, concomitant administration of fluconazole with quinidine may zn cu in inhibition of quinidine metabolism. Use of quinidine has been associated with QT prolongation and rare occurrences of torsades de pointes.

Coadministration of fluconazole and quinidine is contraindicated.
