Clioquinol
Mechanism :
Clioquinol is active against a broad spectrum of microorganisms, including fungi (e.g., Candida, Microsporum, Trichophyton) and gram-positive bacteria (e.g., Staphylococci). Clioquinol has only a slight inhibitory effect on gram-negative bacteria. Clioquinol exerts a bacteriostatic, rather than a bactericidal action.
Indication :
- Nonextensive superficial dermatomycoses
- Infected forms of eczema, pyoderma, and mild burns
Contraindications :
Known hypersensitivity to hydroxyquinolines, clioquinol, or other quinoline derivatives, iodine, as well as to any other components of the preparation. Clioquinol should not be used in children under 2 years of age.
Dosing :
Available as 8% cream
Apply to the affected area in a thin layer 2 to 3 times daily.
Adverse Effect :
Allergic skin reaction
Interaction :
Protein-bound Iodine: Topical use may increase the amount of protein-bound iodine (PBI) in patients with normal thyroid function and therefore may interfere with some thyroid function. These tests should not be performed within a period shorter than 1 month following the use of clioquinol.
Ferric Chloride Test: The ferric chloride test for phenylketonuria may yield a false positive test when trace amounts of clioquinol are present in the urine.
Hepatic Dose :
No dosage adjustments are recommended.
