Laurimic (Fenticonazole Nitrate)

Fenticonazole nitrate is employed to treat superficial fungal infections of the skin and related conditions, offering a broad spectrum of activity against dermatophytes, yeasts and Malassezia species.

• Dermatophytosis (tinea corporis, tinea cruris, tinea pedis): reduces fungal growth and clears lesions.
• Candidal skin infections: eliminates Candida species, relieving erythema and itching.
• Pityriasis versicolor: eradicates Malassezia, restoring normal skin colour and texture.
• Seborrheic dermatitis: controls Malassezia‑related inflammation, reducing scaling and redness.

Effective therapy reduces symptoms, prevents spread and promotes faster skin healing when used as directed.

• Fenticonazole nitrate inhibits the fungal enzyme lanosterol 14α‑demethylase (CYP51), a key step in ergosterol biosynthesis. By blocking this cytochrome P450‑dependent enzyme, the drug disrupts the formation of ergosterol, an essential component of the fungal cell membrane, leading to increased membrane permeability, impaired cell growth and ultimately fungal cell death. The inhibition is selective for fungal enzymes, resulting in minimal impact on human cells.

Topical application of Laurimic may be associated with local skin reactions and, rarely, systemic hypersensitivity.

Common Side Effects

• Burning sensation: mild transient burning at the application site.
• Itching: occasional pruritus around treated area.
• Redness: mild erythema that resolves with continued use.
• Dryness or peeling: temporary skin dryness or flaking.

Serious or Rare Side Effects

• Severe allergic reaction: swelling, hives, or difficulty breathing requiring immediate medical attention.
• Contact dermatitis: intense inflammation, blistering or ulceration at the site.
• Stevens‑Johnson syndrome: rare severe skin reaction with widespread rash and mucosal involvement.

Before using Laurimic, consider the following precautions to ensure safe and effective treatment.

• Application area: apply only to clean, dry, intact skin as directed.
• Duration of therapy: do not exceed the prescribed treatment period without medical advice.
• Concomitant skin conditions: avoid use on extensive eczema, psoriasis or open wounds.
• Pregnancy and lactation: safety not established; use only if the potential benefit outweighs the risk.
• Pediatric use: safety in infants not established; follow prescriber recommendations for children.
• Store at ambient temperature: keep in the original container, protect from moisture and light.

Fenticonazole nitrate may interact with other topical or systemic agents; consider the following.

Major Interactions (Avoid)

• Concurrent use of other topical azole antifungals: may increase local irritation or toxicity.
• Systemic azole antifungals (e.g., itraconazole, fluconazole) applied over large skin areas: may raise systemic exposure and risk of hepatotoxicity.

Moderate Interactions (Monitor Closely)

• Topical corticosteroids: may reduce antifungal efficacy when used simultaneously.
• Skin irritants or harsh cleansers: can exacerbate local irritation.
• Occlusive dressings: may enhance absorption and increase risk of side effects.
