Applications & Uses

Description

Benzydamine hydrochloride is a non-steroidal antiinflammatory drug used both topically and systemically. It has been reported as a sensitizer and a photosensitizer and caused occupational contact dermatitis in a nurse.

Uses

A nonsteroidal anti-inflammatory drug with local anaesthetic, analgesic and antipyretic properties.

Uses

anticholinergic

Uses

A nonsteroidal anti-inflammatory with local anesthetic properties.

Uses

Benzydamine hydrochloride is an anti-in-flammatory drug used extensively in Europe and recently introduced in Canada to help re duce painful mucositis. Benzydamine provides short-term topical anesthesia and extended pain relief apparently through its anti-inflammatory properties. Studies have shown it to be effective in a range of painful conditions, including aphthous ulceration, chemotherapy-induced mucositis, and radiation-induced mucositis.
