Benzydamine Hydrochloride mouthwash is a Non-Steroidal Anti-Inflammatory Drug (NSAID) with analgesic and local anesthetic properties. The clinical pharmacology of Benzydamine mouthwash is well known. Benzydamine is poorly absorbed in the blood, thereby limiting systemic exposure to the drug when applied topically but ensures high concentration at the site of injury in mouth or throat. Therefore, it provides excellent oropharyngeal pain relief with minimal side effects.

Although Benzydamine is a Non-Steroidal Anti-Inflammatory agent, it possesses a different mechanism of action that distinguishes it from conventional NSAIDs. Benzydamine mouthwash shows analgesic & anti-inflammatory action by inhibiting pro-inflammatory cytokines & reducing vascular permeability. Moreover, Benzydamine mouthwash shows local anesthetic property which provides an immediate effect on pain.
