Common NameBenzydamine
DescriptionBenzydamine, also known as bencidamina, belongs to the class of organic compounds known as indazoles. Indazoles are compounds containing an indazole, which is structurally characterized by a pyrazole fused to a benzene. Benzydamine is a very strong basic compound (based on its pKa). It may be used alone or as an adjunct to other therapy giving the possibility of increased therapeutic effect with little risk of interaction. Synthesis starts with the reaction of the N-benzyl derivative from methyl anthranilate with nitrous acid to give the N-nitroso derivative. Benzydamine has been used recreationally. Unlike other NSAIDs, it does not inhibit cyclooxygenase or lipooxygenase, and is not ulcerogenic. Please note there is an error in this section: US3318905 states that the nitroso derivative is reduced with sodium hydrosulfite (sodium dithionite) and not with sodium hyposulfite (sodium thiosulfate), as shown in the above scheme and stated in text. Alternatively, use of chloroacetamide in the alkylation step followed by acid hydrolysis produces bendazac instead. There are no contraindications to the use of benzydamine except for known hypersensitivity. This compound has been identified in human blood as reported by (PMID: 31557052 ). Benzydamine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Benzydamine is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
