Oxeladin citrate is a highly potent and effective cough suppressant, which can treat all types of cough of various etiologies. It is not related to opium or its derivatives, so treatment with oxeladin is no risk of addiction. And it has none of the side effects (such as hypnosis, respiratory depression, tolerance, constipation and analgesia) which are present when common antitussives. It can used at every age, as well as in patients with heart disease, since it is high level of safety and a great selectivity to act on the bulbar centre of cough.
