Benzydamine hydrochloride (HCl) is a topical indolic nonsteroidal anti-inflammatory drug, endowed with analgesic and anesthetic activity, and with antimicrobial (including both gram-positive and gram-negative bacteria) and antifungal properties (targeting\n                    <ns3:italic>Candida albicans<\/ns3:italic>\n                    and non-albicans strains), used in odontostomatology, otorhinolaryngology, and gynecology for its properties. This molecule has a lipophilic nature, showing high affinity with cell membranes and exhibiting membrane stabilization properties, resulting in local anesthesia, an effect related also to the interaction of the drug with cationic channels. Unlike other non-steroidal anti-inflammatory drugs, benzydamine HCl is a weak inhibitor of cyclooxygenase or lipoxygenase and consequently its primary mechanisms of action are not related to arachidonic acid metabolism and do not affect the biosynthesis of the inflammation mediators prostanoids, prostacyclin, thromboxane and leukotrienes. Benzydamine HCl is able to inhibit the production of pro-inflammatory cytokines, with consequent analgesia. Moreover, benzydamine HCl is able to inhibit leukocyte-endothelial interactions and platelet aggregation. Here we review the most updated clinical data available on benzydamine HCl local application as spray, mouthwash or gargling and evidence of its effectiveness in inflammatory and\/or septic conditions in the otorhinolaryngology and odontostomatology settings, with particular reference to sore throat, oral inflammation, dental plaque, tonsillitis\/tonsillectomy and chemo- or radiotherapy-induced oral mucositis. Novel formulations for oral and oromucosal\/buccal\/intraoral administration of benzydamine HCl are also reviewed, including\n                    <ns3:italic>in situ<\/ns3:italic>\n                    gelling formulations to be sprayed onto the damaged oral mucosa. Finally, novel data on the potential role of benzydamine HCl in nociceptor excitability are introduced.\n                  <\/ns3:p>","DOI":"10.12688\/f1000research.144067.2","type":"journal-article","created":{"date-parts":[[2025,5,22]],"date-time":"2025-05-22T12:00:12Z","timestamp":1747915212000},"page":"350","update-policy":"https:\/\/doi.org\/10.12688\/f1000research.crossmark-policy","source":"Crossref","is-referenced-by-count":7,"title":["Benzydamine hydrochloride: an overview on a well-established drug with news in mechanisms of action"],"prefix":"10.12688","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2973-6607","authenticated-orcid":false,"given":"Antonio","family":"Ferrer-Montiel","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2560","published-online":{"date-parts":[[2025,5,22]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"95-107","DOI":"10.1007\/s10787-998-0026-0","article-title":"Pharmacology of benzydamine.","volume":"6","author":"P Quane","year":"1998","journal-title":"Inflammopharmacology."},{"key":"ref2","doi-asserted-by":"publisher","first-page":"481-492","DOI":"10.1002\/bdd.2510120702","article-title":"Pharmacokinetics of benzydamine after intravenous, oral, and topical doses to human subjects.","volume":"12","author":"G Baldock","year":"1991","journal-title":"Biopharm.
