Kofnix® is a preparation of Butamirate Citrate which is a non-opioid central cough suppressant. It acts on the cough center in the medulla oblongata. It is neither chemically nor pharmacologically related to opium alkaloids and is safer than codeine. In addition to its antitussive effect, it also exerts expectorant, moderate bronchodilatory action with anti-inflammatory effects. It decreases the airway resistance and improves blood oxygenation.
