DESCRIPTION OF EMBODIMENT

[0010] 72 hours after the rats have been sensitized by injecting antiserum into the eyelids of the test animals, a fresh provocation was induced in them by intravenous administration of ovalbumin. Some of the experimental animals were pretreated by the administration of solution containing epinastine according to the invention into the conjunctival sac 15 minutes before the ovalbumin is administered. Two hours after the administration of ovalbumin the experimental animals were killed and the conjunctiva was investigated for its content of eosinophils and neutrophils and the mast cell granulation was determined.

Results

[0011] The animals pretreated with epinastine solution according to the invention (0.05-0.5%) had a significantly lower content of eosinophils in their conjunctiva. The animals pretreated with epinastine solution according to the invention had a significantly lower content of lymphocytes in their conjunctiva (p<0.01). In the animals pretreate...
