Intranasal inhalation of beclomethasone dipropionate in the treatment of perennial rhinitis in adults.
Forty-eight perennial rhinitis patients completed a six weeks' open trial of intranasal beclomethasone dipropionate aerosol. Each received a daily dose of 400 micrograms. Thirty-five responded excellently, seven reported satisfactory improvement and six failed. This study indicated that patients with a demonstrable allergic component responded favorably. However, due to the wide margin of safety the authors suggest that it be tried on the non-infective perennial rhinitis with no demonstrable allergic component as well.
