First generation antihistamines: what are they?

Dormidine contains an active substance called doxylamine succinate, which is a first generation antihistamine. . Antihistamines are used for the treatment of allergy, but the first generation, that is, the old ones, also cause sleep. In contrast, the new antihistamines do not cause this drowsiness effect.


The first antihistamines are relatively cheap and widespread. Both doxylamine and other first generation H1 antihistamines cross the blood-brain barrier, causing drowsiness by inhibiting H1-stimulating wakefulness receptors. But they are non-specific drugs, which, in addition, have effects on other receptors (for example, cholinergic receptors).

This lack of selectivity for the receptor is the basis of the poor tolerance profile of some of these products, especially when compared to the second generation of antihistamines H1. The dose of doxylamine to induce sleep can be as low as 6.25 mg, but it is usually effective at doses of up to 25 mg.


Uses of doxylamine

Doxylamine, therefore, is not only used as anti-allergic, but is part of other drugs such as Dormidina or Normodorm, used for occasional sleep. Although, undoubtedly, the Dormidina is the most popular, since its manufacturers have carried out a great marketing campaign turning it into a well-known product .
