Ketoconazol Dr. Max (Ketoconazole)

Ketoconazole is an imidazole antifungal used to treat superficial fungal infections of the skin.

• Seborrheic dermatitis: reduces scaling and erythema caused by Malassezia species.
• Tinea corporis (ringworm): clears dermatophyte infection and restores normal skin appearance.
• Tinea cruris (jock itch): alleviates itching and lesion spread in the groin area.
• Tinea pedis (athlete's foot): eliminates fungal growth on the feet and prevents recurrence.
• Pityriasis versicolor: normalizes skin pigmentation by eradicating Malassezia overgrowth.

• Ketoconazole inhibits the fungal cytochrome P450 enzyme 14α‑demethylase, blocking conversion of lanosterol to ergosterol. This disruption impairs fungal cell membrane synthesis, leading to increased membrane permeability and ultimately fungal cell death. The action is localized to the site of topical application, providing targeted antifungal activity with minimal systemic absorption.

Ketoconazole topical preparations may cause local skin reactions.

Common Side Effects

• Burning sensation: transient heat at the application site.
• Itching: mild pruritus during treatment.
• Redness: localized erythema.
• Dryness: skin may become less moist.
• Scaling: flaking of the treated area.
• Irritation: mild discomfort or stinging.

Serious or Rare Side Effects

• Allergic contact dermatitis: severe rash with swelling.
• Stevens‑Johnson syndrome: rare but life‑threatening skin reaction.
• Angioedema: rapid swelling of face or lips.
• Systemic toxicity: unlikely but possible with extensive use.
• Hepatotoxicity: rare systemic effect if absorbed in large amounts.
• Severe photosensitivity: heightened skin reaction to sunlight.

Before using Ketoconazol Dr. Max, consider the following safety measures.

• Skin assessment: verify no known hypersensitivity to ketoconazole or imidazoles.
• Avoid broken skin: do not apply on open wounds or damaged epidermis.
• Duration limit: follow prescribed treatment length to reduce irritation risk.
• Concomitant topical agents: do not combine with other antifungal or corticosteroid creams unless directed.
• Pregnancy and lactation: consult a healthcare professional before use.
• Store at room temperature: keep in the original container, protect from moisture and heat.

Ketoconazole topical has limited systemic interactions, but caution is advised with certain co‑administered agents.

Major Interactions (Avoid)

• Systemic CYP3A4 inhibitors: concurrent oral ketoconazole or strong inhibitors may increase systemic exposure.
• Other topical antifungals: simultaneous use can raise risk of skin irritation.
• Oral ketoconazole: combined use may lead to additive systemic effects.

Moderate Interactions (Monitor Closely)

• Topical corticosteroids: may enhance local irritation.
• Sunscreen or UV‑protective products: potential increase in photosensitivity.
• Other dermatologic preparations: monitor for reduced efficacy or increased irritation.
