Econazole (commonly used as the nitrate salt) is an antifungal medication of the imidazole class. It is a broad spectrum antimycotic with some action against Gram positive bacteria. It is used topically in dermatomycoses also orally and parenterally. Sold under the brand name Ecoza among others, it is indicated for the treatment of interdigital tinea pedis caused by Trichophyton rubrum, Trichophyton mentagrophytes, and Epidermophyton floccosum in patients 12 years of age and older. Econazole interacts with 14-α demethylase, a cytochrome P-450 enzyme necessary to convert lanosterol to ergosterol. As ergosterol is an essential component of the fungal cell membrane, inhibition of its synthesis results in increased cellular permeability causing leakage of cellular contents. Econazole may also inhibit endogenous respiration, interact with membrane phospholipids, inhibit the transformation of yeasts to mycelial forms, inhibit purine uptake, and impair triglyceride and/or phospholipid biosynthesis.

Posaconazole is a triazole antifungal drug that is used to treat invasive infections by Candida species and Aspergillus species in severely immunocompromised patients. It marketed in the United States, the European Union, and in other countries by Schering-Plough under the trade name Noxafil. Noxafil is used for prophylaxis of invasive Aspergillus and Candida infections in patients, 13 years of age and older, who are at high risk of developing these infections due to being severely immunocompromised as a result of procedures such as hematopoietic stem cell transplant (HSCT) recipients with graft-versus-host disease (GVHD), or due to hematologic malignancies with prolonged neutropenia from chemotherapy. Also for the treatment of oropharyngeal candidiasis, including oropharyngeal candidiasis refractory to itraconazole and/or fluconazole. Posaconazole blocks the synthesis of ergosterol, a key component of the fungal cell membrane, through the inhibition of cytochrome P-450 dependent enzyme lanosterol 14α-demethylase responsible for the conversion of lanosterol to ergosterol in the fungal cell membrane. This results in an accumulation of methylated sterol precursors and a depletion of ergosterol within the cell membrane thus weakening the structure and function of the fungal cell membrane. This may be responsible for the antifungal activity of posaconazole. It is absorbed within three to five hours and predominately eliminated through the liver, and has a half-life of about 35 hours. Oral administration of posaconazole taken with a high-fat meal exceeds 90% bioavailability and increases the concentration by four times compared to fasting state.

Oxiconazole nitrate is 2',4'-dichloro-2-imidazol-1-ylacetophenone (Z)-[0-(2,4-dichlorobenzyl)oxime], mononitrate is an imidazole derivative characterized by a broad fungistatic spectrum. In vitro oxiconazole is highly effective against many dermatophytes, including Trichophyton rubrum, Trichophyton mentagrophytes, Trichophyton tonsurans, and Epidermophyton floccosum. In addition, fungicidal activity of various degree was found in selected species (Aspergillus fumigatus, Cryptococcus neoformans, Candida albicans and Trichophyton mentagrophytes). Synthesis of DNA was inhibited by subinhibitory concentrations of oxiconazole in parallel to cell multiplication, whereas synthesis of RNA, protein and carbohydrate was decreased to a lesser extent. OXISTAT® (Oxiconazole nitrate) Cream and Lotion are indicated for the topical treatment of the following dermal infections: tinea pedis, tinea cruris, and tinea corporis due to Trichophyton rubrum, Trichophyton mentagrophytes, or Epidermophyton floccosum. OXISTAT® Cream is indicated for the topical treatment of tinea (pityriasis) versicolor due to Malassezia furfur. Oxiconazole cream exerts no detectable systemic effect since only a negligible amount is absorbed from the skin. Once-daily use of oxiconazole cream could be valuable in patients with a history of noncompliance with multiple-daily regimens of other topical antifungal agents.

Tioconazole is an antifungal medication of the imidazole class used to treat infections caused by a fungus or yeast. Tioconazole is a broad-spectrum imidazole antifungal agent that inhibits the growth of human pathogenic yeasts. Tioconazole exhibits fungicidal activity in vitro against Candida albicans, other species of the genus Candida, and against Torulopsis glabrata. Tioconazole prevents the growth and function of some fungal organisms by interfering with the production of substances needed to preserve the cell membrane. This drug is effective only for infections caused by fungal organisms. Tioconazole interacts with 14-α demethylase, a cytochrome P-450 enzyme that converts lanosterol to ergosterol, an essential component of the yeast membrane. In this way, tioconazole inhibits ergosterol synthesis, resulting in increased cellular permeability. Tioconazole may also inhibit endogenous respiration, interact with membrane phospholipids, inhibit the transformation of yeasts to mycelial forms and the uptake of purine, impair triglyceride and/or phospholipid biosynthesis, and inhibit the movement of calcium and potassium ions across the cell membrane by blocking the ion transport pathway known as the Gardos channel. Side effects (for the women's formulas) may include temporary burning/irritation of the vaginal area, moderate drowsiness, headache similar to a sinus headache, hives, and upper respiratory infection.

Clotrimazole is an anti-fungal medicine indicated for the treatment of vaginal yeast infections and tinea. It can be used either in combination with other drugs (betamethasone dipropionate) or alone, in form of topical or vaginal cream. The drug exerts its action by inhibiting lanosterol demethylase thereby affecting the growth of fungi.

Miconazole is a synthetic imidazole derivative, a topical antifungal agent for use in the local treatment of vaginal, and skin and nail infections due to yeasts and dermatophytes. It is particularly active against Candida spp., Trichophyton spp., Epidermophyton spp., Microsporum spp. and Pityrosporon orbiculare (Malassezia furfur), but also possesses some activity against Gram-positive bacteria. It binds to the heme moiety of the fungal cytochrome P-450 dependent enzyme lanosterol 14-alpha-demethlyase. Inhibits 14-alpha-demethlyase, blocks formation of ergosterol and leads to the buildup of toxic methylated 14-a-sterols. Miconazole also affects the synthesis of triglycerides and fatty acids and inhibits oxidative and peroxidative enzymes, increasing the amount of active oxygen species within the cell.
