Oxolamine citrate is primarily used as an antitussive agent, meaning it helps to suppress coughing. It is often included in cough syrups and other respiratory medications to alleviate symptoms associated with acute and chronic coughs. The compound works by acting on the cough reflex, reducing the frequency and intensity of coughing episodes. It is particularly beneficial in managing coughs caused by respiratory infections, bronchitis, or other irritants in the airways. Additionally, oxolamine citrate is sometimes combined with other active ingredients, such as expectorants or decongestants, to provide comprehensive relief from respiratory discomfort. Its effectiveness and relatively mild side effect profile make it a common choice in over-the-counter and prescription cough remedies.
