An open assessment of lomudal (disodium cromoglycate) (2 per cent) nasal spray in seasonal allergic rhinitis.

The effect of Disodium cromoglycate (Lomudal, Intal) on allergic rhinitis, given as a solution in a nasal spray, was studied in 23 adult volunteers with grass pollen allergy, none of whom were having hyposensitization therapy. The trial was carried out as an open assessment during the months of June and July, 1972. Two squirts (1.6 mg D.S.C.G.) from the nasal spray were applied to each nostril every 3 h throughout the day. In 80 per cent of subjects the treatment was successful. No side effects were noted, but five patients expressed a preference for a preparation that could be administered at less frequent intervals.
