Iodochlorhydroxyquin (Clioquinol) is an antifungal agent and a member of a family of drugs called hydroxyquinolines. The topical corticosteroids constitute a class of primarily synthetic steroids used as anti-inflammatory and antipruritic agents. Hydrocortisone is a member of this class. Each gram of ALA-QUIN contains 5 mg Hydrocortisone USP and 30 mg Iodochlorhydroxyquin USP in a cream base consisting of purified water, glycerin, cetyl alcohol, polysorbate 80, stearyl alcohol, sodium lauryl sulfate, cetyl palmitate and sorbic acid.
Iodochlorhydroxyquin is a broad-spectrum antibacterial and antifungal. Its precise mechanism of action is unknown. Topical corticosteroids share anti-inflammatory, antipruritic and vasoconstrictive actions. The mechanism of anti-inflammatory activity of the topical corticosteroids is unclear. Various laboratory methods, including vasoconstrictor assays, are used to compare and predict potencies that a recognizable correlation exists between vasoconstrictor potency and therapeutic efficacy in man.
