Dexchlorpheniramine
A first-generation H1 antihistamine with anticholinergic activity: it is the dextrorotatory, pharmacologically active isomer of chlorphenamine, in medical use since 1959 against hay fever and urticaria. This family brings together the active ingredient, pharmacopoeial impurities, nitrosamines and other impurities.
Did you know?Chlorphenamine is a mixture of two mirror-image molecules, like right and left hands: at the human H1 receptor the "right-handed" form binds tens of times more tightly than the other, which adds little to the effect.
