What is Dextromethorphan Polistirex Er ?

Dextromethorphan Polistirex ER is an extended-release formulation of dextromethorphan, a non-narcotic cough suppressant used to alleviate cough associated with minor throat and bronchial irritation. The polistirex encapsulation allows for a gradual release of the active ingredient, providing long-lasting relief with a reduced dosing frequency compared to immediate-release forms. It is commonly used in over-the-counter cough medicines for both adults and children, while ensuring proper dosing to avoid potential side effects such as dizziness or gastrointestinal disturbances.
