Mepyramine
A first-generation H1 antihistamine, also known as pyrilamine, patented in 1943 and in use since 1949: today it is found mainly in creams for insect bites and nettle rash and in some over-the-counter preparations. This family brings together the active ingredient, pharmacopoeial impurities, labelled standards, nitrosamines and other impurities.
Did you know?It is extremely selective: it binds histamine H1 receptors about 130,000 times more than muscarinic receptors, so, unlike many antihistamines of its generation, it has very few anticholinergic effects.
