Description

Isothipendyl is a first generation H1 antagonist (antihistamine) and anticholinergic used as an antipruritic. It is nowadays scarcely used in the first line relief of allergies due to the anticholinergic side effect of somnolence but does have some limited use through topical application in the relief of insect bites and related itching (pruritus).
