Benzidamine hydrochloride is primarily used as a non-steroidal anti-inflammatory drug (NSAID) with local anesthetic and analgesic properties. It is commonly applied in the treatment of inflammatory conditions of the mouth and throat, such as pharyngitis, tonsillitis, and stomatitis. The compound is often formulated as a mouthwash, spray, or lozenge to provide targeted relief from pain and inflammation. Its anti-inflammatory action helps reduce swelling and discomfort, while its anesthetic effect numbs the affected area, offering quick symptom relief. Additionally, benzidamine hydrochloride exhibits antibacterial and antifungal properties, which help reduce the risk of infection in the treated area. It is sometimes used in post-surgical dental care to manage pain and inflammation after procedures. Its localized application minimizes systemic side effects, making it a preferred choice for short-term symptomatic treatment in oral and throat conditions. It should not be used continuously for extended periods without consulting a healthcare professional.
