This study is an open label, single dose, single site, randomized, cross over study that will assess nasal deposition of radioactivity following nasal inhalation of a ciclesonide radiolabeled solution via a novel nasal MDI and of a mometasone furoate monohydrate radiolabeled suspension via an aqueous nasal spray in approximately 10 14 patients with symptomatic allergic rhinitis, aged 18 65 years. In order to ensure that patients will be symptomatic at the time of dosing, participants will be asked to withhold their usual treatments for perennial or seasonal allergic rhinitis, beginning at the Screening Visit until after Study Visit 3.~Each patient will be randomly assigned to one of two treatment sequences. The two treatments in this study are a single dose (one 37 mcg actuation per nostril) of radiolabeled solution of ciclesonide nasal aerosol 74 µg (Regimen A) and a single dose (two 50 mcg actuations per nostril) of a radiolabeled suspension of mometasone aqueous nasal spray 200 µg (Regimen B).
