Sertaconazole is a azole antifungal that is FDA approved for the treatment of interdigital tinea pedis in immunocompetent patients 12 years of age and older, caused by: Trichophyton rubrum, Trichophyton mentagrophytes, and Epidermophyton floccosum. Sertaconazole 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. Common adverse reactions include contact dermatitis, dry skin, burning skin and application site skin tenderness.

Sildenafil (Viagra, Revatio) is a PDE5 inhibitor which was approved by FDA for the treatment of erectile disfunction and adults with pulmonary arterial hypertension. Upon administration sildenafil inhibits PDE5 and results in elevated level of cyclic guanosine monophosphate and smooth muscle relaxation.

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.

Sulconazole (trade name Exelderm) is an antifungal medication of the imidazole class. Sulconazole has a broad spectrum of antifungal activity in vitro and has been shown to be an effective topical antifungal agent for the management of superficial fungal infections of the skin, particularly dermatophytosis and tinea versicolor. Sulconazole inhibits the cytochrome P-450 isoenzyme, C-14-alpha-demethylase by binding to the heme iron of the enzyme. This results in a largely fungistatic effect. The selectivity of azole antifungal agents for pathogenic organisms compared with mammalian cells appears to depend on a preferred affinity of these drugs for fungal versus mammalian cytochrome P-450 sterol demethylases. Enzyme inhibition by sulconazole prevents the synthesis of ergosterol, a sterol found in fungal cell membranes but, in general, not in mammalian cell membranes. Additionally, lanosterol accumulates, which changes membrane permeability, cell volume, secondary metabolic effects, and causes defective cell division and growth inhibition. As sulconazole is primarily fungistatic, an intact immune system may be needed for infection resolution.In selected situations, sulconazole may have growth phase-dependent fungicidal activity against very susceptible organisms. The 1% concentration of sulconazole may greatly exceed the minimum inhibitory concentration and exert a direct physiochemical effect on the fungal cell membrane. The fungicidal effect may be due to hydrophobic interactions between sulconazole and unsaturated fatty acids in the membrane. Mammalian cells generally have little or no unsaturated fatty acids. Sulconazole may also prevent DNA and RNA synthesis and increase their degradation.Sulconazole has activity against many dermatophytes and yeast. One measure of the drug's antifungal activity is the relative inhibition factor (RIF). The RIF approaches 0% for a drug to which a fungus is highly sensitive and 100% for a drug that is non-inhibitory. The RIF values of sulconazole for Candida species, Aspergillus species, and dermatophytes are broadly similar to those of clotrimazole, econazole, ketoconazole, miconazole, and tioconazole. The mean RIF values were 69% (30—98%) for Candida species, 71% (61—82%) for Aspergillus species, and 12% (5—18%) for dermatophytes. Sulconazole is available as a cream or solution to treat skin infections such as athlete's foot, ringworm, jock itch, and sun fungus.

Butoconazole, trade names Gynazole-1, an imidazole antifungal used in gynecology for the local treatment of vulvovaginal candidiasis (infections caused by Candida). The exact mechanism of the antifungal action of butoconazole nitrate is unknown; however, it is presumed to function as other imidazole derivatives via inhibition of steroid synthesis. Imidazoles generally inhibit the conversion of lanosterol to ergosterol, resulting in a change in fungal cell membrane lipid composition. This structural change alters cell permeability and, ultimately, results in the osmotic disruption or growth inhibition of the fungal cell.

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.

Thiamine, also known as vitamin B1, plays a key role in the human metabolism. It is present in many dietary sources such as meats, eggs, fish, beans and peas, nuts, and whole grains. Upon administration thiamine is converted by thiamine pyrophosphokinase-1 (TPK1) to the active form, thiamine pyrophosphate, which serves as a cofactor for enzymes involved in the TCA cycle and the non-oxidative part of the pentose phosphate pathway. The lack of thiamine may cause the thiamine deficiency. The classical syndrome caused primarily by thiamine deficiency in humans is beriberi, however, symptoms of thiamine deficiency also include congestive heart failure, metabolic acidosis, confusion, ataxia and seizures. Thiamine is a component of many vitamin complexes, which are approved for the treatmen and prevention of general vitamin deficiency, including the thiamine deficiency.

Pentaerythritol tetranitrate is an organic nitrate that has been used for the treatment of angina pectoris. Upon administration, the drug undergoes exstensive metabolism to NO which causes vasodilation and the relaxation of smooth muscle cells. The compound belongs to a familiy of explosive substances and may be used accordingly.
