Oxeladin citrate is primarily used as an antitussive agent, which means it is effective in suppressing cough. It is commonly prescribed to alleviate dry, non-productive coughs by acting on the cough center in the brain to reduce the cough reflex. This makes it particularly useful in managing coughs associated with conditions like colds, bronchitis, or other respiratory infections where coughing can be persistent and irritating. It is often included in cough syrups or lozenges for ease of administration and to provide symptomatic relief. However, it should be used under medical supervision, especially in cases of chronic cough or underlying respiratory conditions, to ensure appropriate use and avoid potential side effects.
