Adults: Refer to specific product guidelines for dosing instructions, as it may vary depending on the condition treated and formulation used.

Mechanism of action

Clotrimazole exerts its antifungal effects by inhibiting the enzyme lanosterol 14-alpha-demethylase, which is crucial for the conversion of lanosterol to ergosterol in fungal cell membranes. This reduction in ergosterol synthesis leads to increased membrane permeability and ultimately results in cell death.

Pharmacodynamics

Clotrimazole demonstrates fungicidal and fungistatic activity, depending on the concentration at the site of infection. It is effective against a wide range of fungi, including yeast and dermatophytes. The drug's antifungal activity is enhanced in acidic environments, making it particularly effective for topical applications in cutaneous infections.

Pharmacokinetics

Clotrimazole is poorly absorbed from the gastrointestinal tract when taken orally. Topical formulations allow for localized action with minimal systemic absorption. When applied to the skin or mucous membranes, it penetrates tissues effectively. Peak plasma concentrations are typically achieved within 1 hour for oral formulations, but systemic side effects are rare due to low bioavailability. The elimination half-life is variable, with most of the drug excreted unchanged in the feces.

Pregnancy

Clotrimazole is generally considered safe for use during pregnancy, particularly in topical formulations, but should be used under the guidance of a healthcare provider.

Clotrimazole is excreted in breast milk; caution is advised when using during breastfeeding, particularly with systemic formulations.
