Medication Summary

The goals of pharmacotherapy are to eradicate the infection, to reduce morbidity, and to prevent complications. [30]

Antifungals

Class Summary

The mechanism of action usually involves inhibiting pathways (enzymes, substrates, transport) necessary for sterol/cell membrane synthesis or altering the permeability of the cell membrane (polyenes) of the fungal cell.

Griseofulvin (Fulvicin P/G, Grifulvin V)

Griseofulvin has fungistatic activity. Fungal cell division is impaired by interfering with the microtubule. Griseofulvin binds to keratin precursor cells. Keratin is gradually replaced by noninfected tissue, which is highly resistant to fungal invasions.

Terbinafine (Lamisil)

Terbinafine is a member of the allylamine family and a fungicidal agent that inhibits ergosterol synthesis via squalene epoxidase, which results in a decreased ergosterol level and an increased concentration of squalene; this leads to cell death. Use medication until symptoms significantly improve.

Itraconazole (Sporanox)

Itraconazole has fungistatic activity. It is a synthetic triazole antifungal agent that slows fungal cell growth by inhibiting cytochrome P-450-dependent synthesis of ergosterol, a vital component of fungal cell membranes.

Fluconazole (Diflucan)

Fluconazole has fungistatic activity. It is a synthetic oral antifungal (broad-spectrum bistriazole) that selectively inhibits fungal cytochrome P-450 and sterol C-14 alpha-demethylation, which prevents conversion of lanosterol to ergosterol, thereby disrupting cellular membranes.
