Additional Details

Used for the treatment of actinic keratoses (precancerous skin growths that can become malignant if left untreated).
Masoprocol is a novel antineoplastic agent. It is not known exactly how masoprocol works. Laboratory experiments have shown that masoprocol prevents cells similar to the ones found in actinic keratoses from multiplying. Masoprocol was withdrawn from the U.S. market in June 1996.
Mode of Action:
Although the exact mechanism of action is not known, studies have shown that masoprocol is a potent 5-lipoxygenase inhibitor and has antiproliferative activity against keratinocytes in tissue culture, but the relationship between this activity and its effectiveness in actinic keratoses is unknown. Masoprocol also inhibits prostaglandins but the significance of this action is not yet known.
Symptoms of overdose or allergic reaction include bluish coloration of skin, dizziness, severe, or feeling faint, wheezing or trouble in breathing.
