Ketoisdin

Ketoconazole, the active ingredient in Ketoisdin, is an imidazole antifungal presented as a topical formulation for skin use. It treats common fungal skin infections such as tinea corporis, tinea pedis, tinea cruris, seborrheic dermatitis and pityriasis versicolor in both adults and children.

GNH USA supplies Ketoisdin as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Ketoconazole acts on dermatophyte and yeast infections of the skin, providing antifungal activity across several common conditions.

- Tinea corporis: clears the ring‑shaped rash by inhibiting fungal growth. - Tinea pedis: reduces scaling and itching on the feet. - Tinea cruris: resolves the red, inflamed rash in the groin area. - Seborrheic dermatitis: diminishes flaking and erythema on the scalp and face. - Pityriasis versicolor: restores normal skin pigmentation by eradicating Malassezia species.

Ketoconazole may cause local and systemic reactions, although most are mild and reversible.

Common Side Effects: - Skin irritation: mild burning or stinging at the application site. - Pruritus: itching of the treated area. - Redness: localized erythema. - Dryness: flaky or dry skin where applied.

Serious or Rare Side Effects: - Contact dermatitis: severe allergic skin reaction. - Hepatotoxicity: rare systemic absorption leading to liver enzyme elevation. - Stevens‑Johnson syndrome: extremely rare but severe mucocutaneous reaction.

When using Ketoisdin, consider the following safety measures.

- Avoid ocular contact: rinse eyes thoroughly if exposure occurs. - Do not apply to broken skin: limit use to intact epidermis. - Limit duration: follow prescriber instructions to prevent resistance. - Monitor liver function: consider periodic testing if extensive skin area is treated. - Store below 25°C: keep in the original container, protect from moisture and light.

Ketoconazole can interact with other topical agents and systemic medications.

Major Interactions (Avoid): - Concurrent use with other potent topical corticosteroids: may increase skin atrophy risk. - Systemic azole antifungals: additive hepatotoxic potential.

Moderate Interactions (Monitor Closely): - Topical retinoids: may enhance irritation. - Alcohol‑containing skin products: could increase local burning. - Phototoxic agents: advise sun protection to reduce irritation.
