Benzydamine (also known as Tantum Verde and branded in some countries as Difflam), available as the hydrochloride, is 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.[1]

Medical use

It may be used alone or as an adjunct to other therapy giving the possibility of increased therapeutic effect with little risk of interaction.

In some markets, the drug is supplied as an over-the-counter cream (Lonol in Mexico from Boehringer Ingelheim) used for topical treatment of musculoskeletal system disorders: sprains, strains, bursitis, tendinitis, synovitis, myalgia, periarthritis.

Antimicrobial activity

Studies indicate that benzydamine has notable in vitro antibacterial activity and also shows synergism in combination with other antibiotics, especially tetracyclines, against antibiotic-resistant strains of Staphylococcus aureus and Pseudomonas aeruginosa. [2][3]

Contraindications

There are no contraindications to the use of benzydamine except for known hypersensitivity.

Side effects

Benzydamine is well tolerated. Occasionally oral tissue numbness or stinging sensations may occur.

Pharmacology

It selectively binds to inflamed tissues (Prostaglandin synthetase inhibitor) and is normally free of adverse systemic effects. Unlike other NSAIDs, it does not inhibit cyclooxygenase or lipooxygenase, and is not ulcerogenic.[4]

Recreational use

Benzydamine has been used recreationally. In overdosages it acts a deliriant and CNS stimulant.[4] Such use, particularly among teenagers, has been reported in Poland,[4] Brazil[5][6] and Romania.
