Zipeprol

Zipeprol is a centrally acting cough suppressant developed in France in the 1970s. It is not a morphinan derivative. Zipeprol acts as a local anaesthetic and has mucolytic, antihistamine and anticholinergic properties. It is sold with several brand names such as Zinolta and Respilene. It is not available in the United States or Canada and has been discontinued in Europe. It is still available in some countries in Asia and South America.
Zipeprol has been misused in Korea as a deliriant. Such use is quite dangerous due to the risk of seizures and neurological damage at high dosages.
