9. A stable fixed dose pharmaceutical composition for nasal administration to a human, said composition is a single phase aqueous suspension comprising (1) about 0.025% w/w to about 0.05% w/w mometasone or its salt in particulate form, (2) about 0.6% w/w to about 0.7% w/w olopatadine or its salt in dissolved form, and (3) a hydrocolloid system in an amount sufficient to inhibit phase separation for at least 24 hours when stored at 25±2° C. and 60%±5% relative humidity.
10. The pharmaceutical composition of claim 9 , wherein the composition comprises about 0.025% w/w mometasone furoate.
11. The pharmaceutical composition of claim 9 , wherein the composition comprises about 0.05% w/w mometasone furoate.
12. The pharmaceutical composition of claim 9 , wherein the composition comprises about 0.665% w/w olopatadine hydrochloride.
13. The pharmaceutical composition of claim 9 , wherein the composition further comprises a pharmaceutically acceptable excipient selected from the group consisting of chelating agents, preservatives, buffers, surfactants, isotonicity agent, and any combination of any of the foregoing.
14. The pharmaceutical composition of claim 9 , wherein the composition has a pH of about 3.5-3.9, and an osmolality in the range of about 250 mOsm/kg to about 350mOsm/kg.
15. The pharmaceutical composition of claim 9 , wherein the composition has a viscosity in the range of about 20 cps to about 150 cps.
16. The pharmaceutical composition of claim 9 , wherein the composition has a viscosity in the range of about 20 cps to about 150 cps and is contained in a container, and when delivered as a nasal spray has a spray pattern having a longest axis of 15-75 mm, a shortest axis of 10-65 mm, and an ellipticity of 1-2.
17. A method of treating rhinitis in a human in need thereof comprising administering by the nasal route to the human the pharmaceutical composition of claim 1 .
