According to Mayo Clinic, ketoconazole cream, the active ingredient in Ketgo cream, is an effective topical treatment used to combat infections caused by various fungi and yeasts. Ketgo cream works by killing these fungi or preventing their growth, offering relief from associated symptoms.

Quick Summary

Ketgo cream is an antifungal medication with the active ingredient ketoconazole. It treats common fungal skin infections such as ringworm, athlete's foot, and jock itch. It is also effective against skin yeast infections and seborrheic dermatitis. Always consult a doctor for a proper diagnosis before use.

Key Points

Active Ingredient: Ketgo cream contains ketoconazole, a potent antifungal medication used to treat various skin infections.
Fights Fungal Infections: Its primary uses include treating conditions such as athlete's foot, ringworm, and jock itch, which are caused by fungi.
Treats Yeast and Dermatitis: The cream is also effective against yeast infections of the skin (cutaneous candidiasis), tinea versicolor, and seborrheic dermatitis.
Mechanism of Action: Ketoconazole works by inhibiting ergosterol synthesis, which is crucial for fungal cell membranes, leading to the fungus's death.
Requires Prescription: In many countries, such as the U.S., the 2% ketoconazole cream formulation typically requires a prescription, unlike some lower-strength shampoos.
Proper Application is Key: Users should apply a thin layer to the affected area once or twice daily, following the full course of treatment to prevent recurrence.
Watch for Side Effects: Common side effects are mild, localized reactions like burning or itching, but severe allergic reactions are possible and require immediate attention.

What is Ketgo cream used for? Unpacking its antifungal properties

Ketgo cream, containing the active ingredient ketoconazole, is a topical antifungal medication used to treat superficial fungal and yeast skin infections. Ketoconazole belongs to the imidazole class of antifungals and works by interfering with the synthesis of ergosterol, a vital component of fungal cell membranes. This disruption compromises the cell membrane, leading to the death of the fungus or inhibiting its growth.

Ketgo cream is prescribed for several common skin conditions, including Athlete's foot, Ringworm of the body, Ringworm of the groin (jock itch), Seborrheic dermatitis, Tinea versicolor, and Cutaneous candidiasis.

How does Ketgo cream work?

Ketoconazole is a broad-spectrum antifungal that targets fungal cell membranes by inhibiting the enzyme necessary for ergosterol synthesis. Ergosterol is essential for maintaining the stability and integrity of the fungal cell membrane. By blocking its production, ketoconazole disrupts the membrane, causing it to become permeable and lose vital components. This leads to cellular dysfunction and the death of the fungal cell.

Proper application and important considerations

Correct application is vital for the cream's effectiveness and to prevent infection recurrence. Clean and dry the affected area, wash hands before and after application, and apply a thin, even layer covering the infected area and a small portion of surrounding healthy skin. Unless advised by a doctor, do not cover the treated area with bandages.
