Benzydamine, available as the hydrochloride, is a locally-acting nonsteroidal anti-inflammatory drug with local anaesthetic and analgesic properties providing both rapid and extended pain relief as well as a significant anti-inflammatory treatment for the painful inflammatory conditions of the mouth and throat.[1]

It selectively binds to inflamed tissues (Prostaglandin synthetase inhibitor) and is virtually free of any adverse systemic effects.

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

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. Benzydamine may be abused recreationally.[4] In oral dosages of 500 mg to 3000 mg it is a deliriant and CNS stimulant (a cough drop has 3 mg dose), popular in Poland, Brazil and Romania. In Brazil it is very popular and widely used for recreational purposes, particularly among teenagers and as a club drug.[5] A person in a benzydamine trip may experience (because of large dopamine release) a feeling of well-being, euphoria and, in higher doses, hallucinations, paranoia, dry mouth and convulsions. The trip can last up to 8 hours, after that the user becomes tired and quiet, but sleeping is almost impossible. Unlike other NSAIDs, it does not inhibit cyclooxygenase or lipooxygenase, and is not ulcerogenic.[4]
