Efficacy Of Bacterial Lysate In Children With Allergic Rhinitis

Summary

This study evaluate the efficacy of Polyvalent Mechanical Bacterial Lysate (PMBL - Ismigen) to improve the clinical course of grass pollen-induced allergic rhinitis (using: TNSS, TOSS, VAS, PNIF) in children aged 5 to 17. Half of the 70 participants will receive PMBL while the other half will receive placebo.
