[Effect of loratadine in children with allergic rhinitis]. / A loratadin hatásai allergiás rhinitisben szenvedö gyermekeknél.

The authors examined 25 children with allergic rhinitis, who were sensitive to grass, weed and tree pollens. During the allergic season nasal lavage was performed then repeated after 4 weeks of loratadine treatment. Tryptase, IL-5, ECP, TNF-alpha and RANTES levels were measured from the nasal lavage fluid. Tryptase, IL-5, and ECP levels were decreased significantly while the decrease of RANTES and TNF-alpha levels was not significant. The authors emphasize that loratadine is an effective anti-inflammatory drug which affects the early and late phase of immediate hypersensitivity. In the moderate cases loratadine is enough to relieve the symptoms, while in the severe forms anti-allergic eye drops and nasal antihistamine or steroid spray has to be added.
