Abstract
Abstract An antihistamine of the benzhydrylether, alkylamine, or benzocyloheptatiophene class is suitable for use in the therapeutic treatment or prophylaxis of reversible airways obstruction by inhalation. The antihistamine may be clemastine, chlorpheniramine or ketotifen and may be in the form of a composition in admixture with a diluent. The antihistamine can be administered from a pharmaceutical inhalation device which is designed to administer a dosage unit of the antihistamine. The inhalation device can be in the form of a pressurized aerosol inhaler or a dry powder insufflator.
