Synonyms
Contact dermatitis; Nitroglycerin
Glyceryl trinitrate (nitroglycerin) can be topically applied as a patch to induce systemic vasodilatation or an ointment around the anus to relax the muscle tonus of the sphincter ani and thus relief the pain due to anal fissures. While delayed-type hypersensitivity sensitization to nitroglycerin is not a common event, it can be the cause of chronic anal eczema, which often is misdiagnosed due to other potential trigger factors such as localized microbial infection or chronic irritation of the fissure. Patch testing will reveal the allergic reaction.
