Although antihistaminics are usually effective to improve symptoms caused by allergic rhinitis, they have some drawbacks such as limited duration of the effect or causing drowsiness in some patients.
A new antihistamine Y-5274 was tried in 100 cases of allergic and vasomotor rhinitis and its effect was studied by double blind method.
The dose used was 6 tablets a day for adults and 3 tablets a day for children.
In comparison to a placebo, the active drug showed significant effect for improvement of sneezing, nasal obstruction and nasal discharge.
