Overview

Overview

Clofedanol (INN) or chlophedianol (BAN) is a centrally acting cough suppressant used in the treatment of dry cough. Clofedanol has local anesthetic and antihistamine properties, and may have anticholinergic effects at high doses.[1] It is marketed in Canada under the trade name Ulone, but is not available currently in the United States. In August 2009, Centrix Pharmaceutical announced the launch of a cough syrup containing a mixture of clophedianol and pseudoephedrine, marketed under the brand name Clofera. It has a release to market date in the beginning of the fourth quarter 2009.[2] Chlophedianol was approved for OTC status in 1987 by the FDA OTC monograph process[3] and its safety and efficacy data are limited.
