Subjects with perennial allergic rhinitis will be randomized to 320 mcg of beclomethasone dipropionate (BDP) using a hydrofluoroalkane (HFA) propellant or placebo as a nasal aerosol. The subjects will be followed for safety and efficacy for a period of 30 or 52 weeks. BDP HFA is a steroid which is currently FDA approved for the treatment of asthma. BDP-HFA should be safe and effective as a "dry" nasal aerosol which may be preferred by some patients.
