Glucophage belongs to Diabetes Treatment while Diflucan belongs to Antifungal Medications. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action

Diflucan: Fluconazole is a triazole antifungal that inhibits the cytochrome P450-dependent enzyme lanosterol 14-alpha-demethylase, blocking the synthesis of ergosterol from lanosterol.
When Glucophage is preferred
