4 Superficial candidiasis Oral 50 100 mg Tablet For superficial or mucosal candidiasis (other than genital candidiasis); Treatment usually continues for 7 to 14 days in oropharyngeal candidiasis (except in severely immunocompromised patients), for 14 days in atrophic oral candidiasis associated with dentures, and for 14 to 30 days in other mucosal candidal infections.
5 Cryptococcal meningitis Oral / i.v 400 mg Given daily as tablet or intravenous infusion; Above dose is followed by a maintenance dose of 200 to 400 mg OD. Duration of therapy is based on clinical and mycological response, but is usually at least 6 to 8 weeks.
6 Systemic candidiasis Oral / i.v 400 mg Given daily as tablet or intravenous infusion, followed by a maintenance dose of 200 to 400 mg OD. Duration of therapy is based on clinical and mycological response.
7 Acute cryptococcal meningitis in AIDS patients Oral / i.v 100 200 mg Given Daily as tablet or intravenous infusion, to prevent relapse after a primary course of antifungal treatment for acute cryptococcal meningitis in AIDS patients.
8 Immunocompromised patients at risk of fungal infections Oral / i.v 50 400 mg Given prophylactically; Daily as tablet or intravenous infusion, although long-term prophylaxis has been associated with the emergence of resistant organisms.
9 VULVOVAGINAL INFECTION Oral 150 mg Tablet Given as a single dose.
10 Candiduria 200 400 mg Given per day for 14 days. Ref Harrison, pg no. 2395.

  ►    Mechanism of Drug Drug Interaction :  In general, fewer interactions are considered to occur with fluconazole than with either itraconazole or ketoconazole. Use of rifampicin with fluconazole results in reduced plasma concentrations of fluconazole. Fluconazole may interfere with the metabolism of some other drugs, mainly through inhibition of the cytochrome P450 isoenzymes CYP3A4 and CYP2C9. This may account for the reported increases in plasma concentrations of bosentan, ciclosporin, midazolam, nevirapine, amitriptyline, nortriptyline, phenytoin, rifabutin, sulfonylurea hypoglycaemics and nateglinide, selective cyclo-oxygenase-2-inhibitors such as celecoxib and parecoxib, tacrolimus, triazolam, warfarin, and zidovudine; fluconazole may inhibit the formation of a toxic metabolite of sulfamethoxazole. Increases in terfenadine concentrations following high doses of fluconazole have been associated with ECG abnormalities. A similar effect may be anticipated with astemizole. Use of fluconazole with cisapride could result in increased cisapride concentrations and associated toxicity. The use of fluconazole with astemizole, cisapride, or terfenadine should therefore be avoided because of the risk of cardiac arrhythmias. Syncope attributed to increased amitriptyline concentrations has occurred when amitriptyline was given with fluconazole. Fluconazole may also reduce the clearance of theophylline. The concentration of contraceptive steroids has been reported to be both increased and decreased in patients receiving fluconazole and the efficacy of oral contraceptives may be affected.,

  ►  Mechanism of Action :   At concentrations achieved following systemic administration, the major effect of imidazoles and triazoles on fungi is inhibition of 14-a-sterol demethylase, a microsomal CYP. Imidazoles and triazoles thus impair the biosynthesis of ergosterol for the cytoplasmic membrane and lead to the accumulation of 14-a-methylsterols. These methylsterols may disrupt the close packing of acyl chains of phospholipids, impairing the functions of certain membrane-bound enzyme systems, thus inhibiting growth of the fungi.,
