    Mechanism of Action

    Ketoconazole usually is fungistatic in action, but may be fungicidal at high concentrations after prolonged incubation or against very susceptible organisms.

    Like other azole antifungal agents, ketoconazole presumably exerts its antifungal activity by altering and damaging cellular membranes, resulting in increased membrane permeability, secondary metabolic effects, and growth inhibition of fungal cells. Although the exact mechanism of action of ketoconazole has not been fully determined, it has been suggested that the fungistatic activity of the drug may result from interference with ergosterol synthesis, probably via inhibition of C-14 demethylation of sterol intermediates (e.g., lanosterol). The fungicidal activity of ketoconazole at high concentrations may result from a direct physiochemical effect of the drug on the fungal cell membrane.

    Ketoconazole 2% shampoo is an imidazole antifungal administered topically for scale washing. It is given in candidiasis and dermatophyte infections of the scalp for prophylaxis and treatment. It indicated for treatment of dandruff and seborrheic dermatitis. It has been given for the prophylaxis of fungal infections in immunocompromised patients, although fluconazole or itraconazole are usually preferred. It has been recommended that, because of its erratic absorption and slow therapeutic response, ketoconazole should not be used for the treatment of life-threatening fungal infections, including fungal meningitis, or for severe infections in immunocompromised patients.

    Antimicrobial action and microbial sensitivity

    Ketoconazole is a broad-spectrum synthetic antifungal agent which inhibits the growth of the following common dermatophytes and yeasts by altering the permeability of the cell membrane: dermatophytes: Trichophyton rubrum, T. mentagrophytes, T. tonsurans, Microsporum canis, M. audouini, M. gypseum and Epidermophyton floccosum; yeast:Candida albicans, C. tropicalis, Pityrosporum ovale and Pityrosporum orbiculare (M. furfur).Development of resistance by these microorganisms to ketoconazole has not been reported.

    Ketoconazole has activity against some Gram-positive bacteria and some antiprotozoal activity against Leishmania spp. There are rare reports of Candida albicans acquiring resistance to ketoconazole. Pharmacological activity of ketoconazole depends on its concentration in different pharmaceutical forms.

    The emergence of strains of Candida spp. resistant to ketoconazole has become increasingly important, particularly in immunocompromised patients receiving long-term prophylaxis with fluconazole. In addition to resistance in C. albicans, infections with C. dubliniensis, C. glabrata, and C. krusei, all of which may be less sensitive to ketoconazole than C. albicans, have been noted in these patients, and secondary resistance of C. glabrata has been reported during ketoconazole therapy.

    Ketoconazole 2% shampoo was not detected in plasma in 39 patients who shampooed 4-10 times per week for 6 months, or in 33 patients who shampooed 2-3 times per week for 3-26 months ( mean: 16 months). Systemic absorption following topical application in healthy subjects practically absents and has not any notable clinical effect.

    Uses and Administration
    Ketoconazole 2% shampoo is used for the treatment of fungal infections, pityriasis versicolor and conditions like seborrheic dermatitis and dandruff. Shampoo controls flaking, scaling and itching, associated with dandruff.


    Shampoo should be applied on scalp for 3-5 minutеs once daily and then washed away with warm water.

    Rare (≥1/10,000 to ≤ 1/1,000);
    Very rare (<1/10,000) including isolated reports; Skin and Subcutaneous Tissue Disturbances. Violations of the skin and subcutaneous tissue:
    Very rare: angioedema, urticarial, hair colour changes.

    Pregnancy and Lactation
    Ketoconazole for topical use lists to Category B. Via to (for it’s ) negligible systemic absorption it is not contraindicated in pregnancy and during breast feeding.
    No adverse effects were seen in a breast-feed infant whose mother was applying ketoconazole topically. The American Academy of Pediatrics considers that the use of ketoconazole is therefore usually compatible with breast feeding.

    Pediatric Precautions
