Abstract
The present invention is directed to a method for treating allergic rhinitis without causing an adverse effect of bitter taste. The method comprises administering to a patient an aqueous pharmaceutical formulation comprising 0.1-0.15% (w/v) of epinastine or an acid addition salt thereof, 0.05-0.5% (w/v) of hydroxypropylmethylcellulose to maintain the viscosity between 1.5-10 centipoise, 1-2% (w/v) of propylene glycol, and a buffer to maintain the pH between 5-8, said aqueous epinastine formulation has a tonicity between 200-400 mOsm/kG; the formulation does not contain a sweetening agent. The present invention provides a method for effectively treating allergic rhinitis by delivering a small volume of the epinastine formulation to the nose of a patient using a small volume metered-dose nasal spray pump. The present method does not cause an adverse effect of bitter taste without including sweetening agents in the formulation.
