sores caused by radiation therapy. Odontostomatologists treats patients of gingivitis,
stomatitis, glossitis, aphthous ulcers, dental surgery and oral ulceration due to radiation
therapy. It is available as the hydrochloride salt and a locally acting nonsteroidal anti-
inflammatory drug with local anaesthetic and analgesic properties for pain relief and anti-
inflammatory treatment of inflammatory conditions of the mouth and throat.
Otorhinolaryngologists prescribed it in the treatment of glandular fever, pharyngitis, tonsillitis,
post-tonsillectomy, and radiation or intubation mucositis. Benzydamine is also used alone or
as an adjunct to other therapy giving the possibility of increased therapeutic effect with little
risk of interaction.
Benzydamine is sold under the brand name Tantum Verde Difflam and Septabene to name
a few across countries.

How does Benzydamine work?
Benzydamine actions effect the local mechanisms of inflammation such as pain, oedema or
granuloma specifically. When applied topically, it demonstrates anti-inflammatory activity
reducing oedema as well as exudate and granuloma formation. It also has analgesic
properties when the source of pain is an inflammatory condition and local anesthetic activity.
Benzydamine poorly affects Hyperthermia indicative of systemic functional involvement.
Furthermore, Benzydamine is a weak inhibitor of the prostaglandin synthesis. It exerts its
effects mostly through inhibition of the synthesis of proinflammatory cytokines including
tumour necrosis factor-alpha without significantly affecting other pro-inflammatory or anti-
inflammatory cytokines.. The local anesthetic activity of the compound has been related to
an interaction with cationic channels.
