Itraconazole
A triazole antifungal agent that inhibits cytochrome P-450-dependent enzymes required for ERGOSTEROL synthesis.
Antifungal Agents
Triazoles
Triazoles are a class of antifungal drugs that contain a triazole ring in their chemical structure and work by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes, thereby disrupting the integrity and function of the membrane.

Ketoconazole
Fluconazole
Triazole antifungal agent that is used to treat oropharyngeal CANDIDIASIS and cryptococcal MENINGITIS in AIDS.
Mycoses
Drug Resistance, Fungal
The ability of fungi to resist or to become tolerant to chemotherapeutic agents, antifungal agents, or antibiotics. This resistance may be acquired through gene mutation.
Candida
A genus of yeast-like mitosporic Saccharomycetales fungi characterized by producing yeast cells, mycelia, pseudomycelia, and blastophores. It is commonly part of the normal flora of the skin, mouth, intestinal tract, and vagina, but can cause a variety of infections, including CANDIDIASIS; ONYCHOMYCOSIS; vulvovaginal candidiasis (CANDIDIASIS, VULVOVAGINAL), and thrush (see CANDIDIASIS, ORAL). (From Dorland, 28th ed)

Infection resulting from inhalation or ingestion of spores of the fungus of the genus HISTOPLASMA, species H. capsulatum. It is worldwide in distribution and particularly common in the midwestern United States. (From Dorland, 27th ed)
Candidiasis
Infection with a fungus of the genus CANDIDA. It is usually a superficial infection of the moist areas of the body and is generally caused by CANDIDA ALBICANS. (Dorland, 27th ed)
Pyrimidines
Drug Resistance, Multiple, Fungal
The ability of fungi to resist or to become tolerant to several structurally and functionally distinct drugs simultaneously. This resistance phenotype may be attributed to multiple gene mutations.
Dermatomycoses
Superficial infections of the skin or its appendages by any of various fungi.
Sporotrichosis
The commonest and least serious of the deep mycoses, characterized by nodular lesions of the cutaneous and subcutaneous tissues. It is caused by inhalation of contaminated dust or by infection of a wound.
Chromoblastomycosis
Scaly papule or warty growth, caused by five fungi, that spreads as a result of satellite lesions affecting the foot or leg. The extremity may become swollen and, at its distal portion, covered with various nodular, tumorous, verrucous lesions that resemble cauliflower. In rare instances, the disease may begin on the hand or wrist and involve the entire upper extremity. (Arnold, Odom, and James, Andrew's Diseases of the Skin, 8th ed, p362)
Meningitis, Fungal

Drug Interactions
Fungi
A kingdom of eukaryotic, heterotrophic organisms that live parasitically as saprobes, including MUSHROOMS; YEASTS; smuts, molds, etc. They reproduce either sexually or asexually, and have life cycles that range from simple to complex. Filamentous fungi, commonly known as molds, refer to those that grow as multicellular colonies.
Candidiasis, Oral
Infection of the mucous membranes of the mouth by a fungus of the genus CANDIDA. (Dorland, 27th ed)
Aspergillosis, Allergic Bronchopulmonary
Hypersensitivity reaction (ALLERGIC REACTION) to fungus ASPERGILLUS in an individual with long-standing BRONCHIAL ASTHMA. It is characterized by pulmonary infiltrates, EOSINOPHILIA, elevated serum IMMUNOGLOBULIN E, and skin reactivity to Aspergillus antigen.
Echinocandins
Cyclic hexapeptides of proline-ornithine-threonine-proline-threonine-serine. The cyclization with a single non-peptide bond can lead them to be incorrectly called DEPSIPEPTIDES, but the echinocandins lack ester links. Antifungal activity is via inhibition of 1,3-beta-glucan synthase production of BETA-GLUCANS.
Clotrimazole
Sporothrix
A mitosporic Ophiostomataceae fungal genus, whose species Sporothrix schenckii is a well-known animal pathogen. The conidia of this soil fungus may be inhaled causing a primary lung infection, or may infect independently via skin punctures.
Blastomycosis
A fungal infection that may appear in two forms: 1, a primary lesion characterized by the formation of a small cutaneous nodule and small nodules along the lymphatics that may heal within several months; and 2, chronic granulomatous lesions characterized by thick crusts, warty growths, and unusual vascularity and infection in the middle or upper lobes of the lung.
Candida albicans
A unicellular budding fungus which is the principal pathogenic species causing CANDIDIASIS (moniliasis).
Cryptococcus neoformans
Naphthalenes
Candidiasis, Vulvovaginal
Infection of the VULVA and VAGINA with a fungus of the genus CANDIDA.
Terfenadine
Pseudallescheria
Paecilomyces
A mitosporic fungal genus occasionally causing human diseases such as pulmonary infections, mycotic keratitis, endocarditis, and opportunistic infections. Its teleomorph is BYSSOCHLAMYS.
Drug Incompatibility
The quality of not being miscible with another given substance without a chemical change. One drug is not of suitable composition to be combined or mixed with another agent or substance. The incompatibility usually results in an undesirable reaction, including chemical alteration or destruction. (Dorland, 27th ed; Stedman, 25th ed)
Ergosterol
A steroid of interest both because its biosynthesis in FUNGI is a target of ANTIFUNGAL AGENTS, notably AZOLES, and because when it is present in SKIN of animals, ULTRAVIOLET RAYS break a bond to result in ERGOCALCIFEROL.
Fungemia
The presence of fungi circulating in the blood. Opportunistic fungal sepsis is seen most often in immunosuppressed patients with severe neutropenia or in postoperative patients with intravenous catheters and usually follows prolonged antibiotic therapy.
Absidia
A genus of zygomycetous fungi, family Mucoraceae, order MUCORALES, which sometimes causes infection in humans.
Penicillium

A chronic inflammatory disease of the skin with unknown etiology. It is characterized by moderate ERYTHEMA, dry, moist, or greasy (SEBACEOUS GLAND) scaling and yellow crusted patches on various areas, especially the scalp, that exfoliate as dandruff. Seborrheic dermatitis is common in children and adolescents with HIV INFECTIONS.
Opportunistic Infections
Sterol 14-Demethylase
An NADPH-dependent P450 enzyme that plays an essential role in the sterol biosynthetic pathway by catalyzing the demethylation of 14-methyl sterols such as lanosterol. The enzyme acts via the repeated hydroxylation of the 14-methyl group, resulting in its stepwise conversion into an alcohol, an aldehyde and then a carboxylate, which is removed as formic acid. Sterol 14-demethylase is an unusual cytochrome P450 enzyme in that it is found in a broad variety of organisms including ANIMALS; PLANTS; FUNGI; and protozoa.
Malassezia
A mitosporic fungal genus that causes a variety of skin disorders. Malassezia furfur (Pityrosporum orbiculare) causes TINEA VERSICOLOR.

Infection in humans and animals caused by fungi in the class Zygomycetes. It includes MUCORMYCOSIS and entomophthoramycosis. The latter is a tropical infection of subcutaneous tissue or paranasal sinuses caused by fungi in the order Entomophthorales. Phycomycosis, closely related to zygomycosis, describes infection with members of Phycomycetes, an obsolete classification.
