Ketoconazole

Ketoconazole is a synthetic antifungal drug used to prevent and treat skin and fungal infections, especially in immunocompromised patients such as those with AIDS. Ketoconazole is sold commercially as an anti-dandruff shampoo also. Ketoconazole is usually prescribed for topical infections such as athlete's foot, ringworm, and candidiasis (yeast infection or thrush).

Ketoconazole is best absorbed at highly acidic levels, so antacids or other causes of decreased stomach acid levels will lower the drug's absorption when taken orally.

The anti-dandruff shampoo is designed for people who have a more serious case of dandruff where symptoms include, but are not limited to constant non-stop flaking, and severe itchiness.
