Embodiment 1

[0225] Two mixtures I and II were prepared respectively by mixing the ingredients listed in Table 1. 5 parts by weight of Mixture I were mixed with 20 parts by weight of Mixture II for 15 minutes or more. The pH of the combined mixture was adjusted to 6.2-6.4 using 1N NaOH to obtain the composition of the invention.

[0229] Alternatively, pure water can be replaced with oils such as cod liver oil, peanut oil, sesame oil, coconut oil, sunflower oil, corn oil or olive oil to prepare oil-based formulations containing compounds of formula IV.

Embodiment 2

[0231] Two mixtures I and II were prepared respectively by mixing the ingredients listed in Table 2. 5 parts by weight of Mixture I were mixed with 20 parts by weight of Mixture II for 15 minutes or more. The pH of the combined mixture was adjusted to 6.2-6.4 using 1 N NaOH to obtain the composition of the invention.

Abstract

A composition for treating, controlling, reducing, ameliorating, or preventing allergy comprises a dissociated glucocorticoid receptor agonist ('DIGRA'), a prodrug thereof, a pharmaceutically acceptable salt thereof, or a pharmaceutically acceptable ester thereof. The composition can comprise an anti-allergic medicament and / or an additional anti-inflammatory agent and can be formulated for topicalapplication, injection, or implantation. The anti-allergic medicament can comprise an antihistamine, a mast-cell stabilizer, a leukotriene inhibitor, an immunomodulator, an anti-IgE agent, or a combination thereof.

Description

Background of the invention [0001] The present invention relates to compositions and methods for treating, controlling, alleviating, ameliorating or preventing allergy. In particular, the present invention relates to compositions comprising isolated glucocorticoid receptor agonists ("DIGRAs") and methods for treating, controlling, alleviating, ameliorating or preventing allergic reactions. More particularly, the present invention relates to compositions and methods for treating, controlling, alleviating, ameliorating or preventing ocular allergy. [0002] An allergy is an overreaction of the body's immune system to foreign substances, called allergens. Inflammatory responses mediated by the immune system are generally divided into four categories: I, II, III and IV. Allergic responses are immediate hypersensitivity reactions of type I reactions in which the individual's body is hypersensitized and develops IgE type antibodies to typical allergens. Mast cells are key compone...
