A single-center, double-blind, study of ragweed-sensitive AR subjects (n = 310) was performed in the Environmental Exposure Unit (EEU) where they were exposed to ragweed pollen.
The onset of action of loratadine/montelukas (L/M) for total symptom score (TSS) was 1 hour and 15 minutes (p = 0.005 versus placebo). L/M was well tolerated.
Medications for Allergic Rhinitis.

Not relevant if not a randomized study (abstract does not tell). The well-known neuro-psychiatric AEs of montelukast will not show in such a small single-dose study. Seems like marketing-reseach to me!
