It inhibits the enzyme squalene epoxidase with a net effect of decreasing ergosterol formation.1 The different mechanism of action results in a different adverse effects profile ( i.e. Terbinafine's mechanism of action differs from that of the azoles. Decreased synthesis of testosterone, cortisol, cholesterol, and androgens may occur during azole administration.1 Lanosterol-14alpha-demethylase is present in most species of yeasts and molds with the exception of Pythium species.2 Lanosterol-14alpha-demethylase is also present in Leishmania species, which explains the variable activity of the azoles in leishmaniasis.3-5 The azoles have a higher affinity for fungal CYP than they do for mammalian CYP however, adverse effects in mammals are due in part to inhibiting mammalian CYP. Ergosterol depletion results in disruption of cell wall function. This enzyme is responsible for forming ergosterol. The azole antifungal drugs have a similar mechanism of action, which is inhibiting the cytochrome P (CYP)-450-dependent enzyme, lanosterol-14alpha-demethylase.

Terbinafine is not an azole antifungal drug, but it has a broad spectrum of activity against many yeast and fungal organisms. The azole antifungal drugs were first discovered in the early 1970s, with ketoconazole being the first orally active azole antifungal.1 The azoles have a broad spectrum of antifungal activity, but important differences exist. This review addresses the mechanisms of action, potential indications, pharmacokinetics, adverse effects, and recommendations for the use of several azole antifungal drugs-ketoconazole, itraconazole, fluconazole, voriconazole, and posaconazole-as well as terbinafine in veterinary patients. The development of newer antifungals such as itraconazole, fluconazole, voriconazole, and posaconazole has been spurred on by the occurrence of resistance in fungal organisms, as seen in bacteria. With the introduction of generic formulations, prescribing many of them is no longer cost-prohibitive. It’s best you don’t use it on anyone under the age of 12 unless instructed by their pediatrician.Although griseofulvin is the only antifungal approved for systemic administration by the Food and Drug Administration (FDA) for veterinary use, a variety of systemic antifungals are available for use in veterinary medicine. The safety of ketoconazole also hasn’t been well-studied in children. If you’re pregnant and have concerns about using an antifungal treatment, talk to your doctor before using even the OTC version of this antifungal shampoo. Ketoconazole’s effects on women who are pregnant or breastfeeding aren’t well-studied. swelling of the face, tongue, or throat.Seek immediate medical attention if you have signs of an allergic reaction like: Signs of allergic reactionĪllergic reactions to ketoconazole shampoo are extremely rare, but should be taken seriously. In rare cases, ketoconazole shampoo can result in hair loss, so talk to your doctor right away if you notice this side effect. It can cause permed hair to lose its curl as well. In some individuals, it may also cause either oiliness or dryness of the hair or scalp, abnormal hair texture, or discoloration.

One of the most common side effects is skin irritation, which can take the form of pimple-like bumps where it’s used.
Ketoconazole can have negative side effects that you should be aware of before using it. One small pilot study consisting of 15 people with alopecia, for example, found that ketoconazole may be able to improve hair regrowth. While ketoconazole is most frequently used for its antifungal properties to treat infections or conditions like seborrheic dermatitis, there is anecdotal evidence indicating that it may also help promote hair growth or reduce hair loss. Tinea versicolor is a skin infection that’s caused by an overgrowth of a type of yeast that naturally lives on your skin. Tinea capitis is a superficial, ringworm-like fungus infection that affects the scalp. Ketoconazole shampoo can also treat tinea capitis and tinea versicolor. Prescription ketoconazole may be needed for psoriasis flares. Yeast-like fungus often infects these skin plaques. Ketoconazole is a common treatment for psoriasis, another inflammatory skin disease that causes skin flaking, skin plaques, and redness. Ketoconazole can help treat dandruff by reducing the fungus and inflammation. Seborrheic dermatitis may be associated with an overgrowth of Malassezia, a yeast fungus that’s naturally present on your skin. Dry scalp causes some dandruff, while other dandruff is actually seborrheic dermatitis. Ketoconazole shampoo is commonly advertised as a dandruff treatment, with OTC brands like Nizoral available in supermarkets or online for purchase.
