Used primarily as a non-opioid antitussive, it effectively suppresses dry and irritating coughs without significant sedative effects commonly seen with other cough medications. Its mechanism involves peripheral inhibition of cough reflex, making it suitable for both acute and chronic respiratory conditions associated with cough. It is commonly formulated in syrup, tablets, or drops for adult and pediatric use. Due to its favorable safety profile and minimal impact on the central nervous system, it is preferred in patients requiring daytime cough relief without drowsiness.
