Embodiment Construction

[0007] It has been found, surprisingly, that topically administrable aqueous solutions containing epinastine, optionally in the form of its racemate, its enantiomers and possibly in the form of the pharmacologically acceptable acid addition salts thereof, may be used to solve the problem on which the invention is based, since they inhibit the influx of neutrophils and eosinophils into the tissue of the ocular conjunctiva and nasal mucous membrane, thereby reducing or preventing the occurrence of LPR and are accordingly characterized by a longer lasting duration of activity.

[0008] The compound epinastine (3-amino-9,13b-dihydro-1H-dibenz-[c,f]imidazol[1,5-a]azepine) and the acid addition salts thereof were described for the first time in German Patent Application P 30 08 944.2.

[0009] The effect of the topically administered solutions containing epinastine as inhibitors of the influx of eosinophils and neutrophils was demonstrated using the so-called passive ocular anaphylaxis model ...

Abstract

A method for treating allergic rhinitis, comprising topically administering to the nasal mucus membrane of a host in need of such treatment a solution comprising: epinastine, optionally in the form of its racemate, its enantiomers, or its pharmacologically acceptable acid addition salts, in a pharmacologically acceptable carrier.

Description

RELATED APPLICATIONS [0001] This application is a continuation of U.S. Ser. No. 10 / 271,180, filed Oct. 15, 2002, which is a continuation of U.S. Ser. No. 09 / 706,650, filed Nov. 6, 2000, now abandoned, which claims priority to German Application No. 199 54 516.2, filed Nov. 12, 1999, and claims benefit of U.S. Provisional Application Ser. No. 60 / 167,771, filed on Nov. 29, 1999, each of which is hereby incorporated by reference.FIELD OF THE INVENTION [0002] The invention relates to topically administered aqueous solutions containing epinastine, optionally in the form of its racemates, its enantiomers, and optionally in the form of the pharmacologically acceptable acid addition salts thereof. BACKGROUND OF THE INVENTION [0003] Allergic reactions of the eye (hereinafter referred to as ocular allergic reactions) signifies a series of differently defined syndromes. The following are examples of ocular allergic reactions, e.g., seasonal allergic conjunctivitis, perennial allergic conjuncti...
