[Inhalation of levopromazine (Nozinan) in the treatment of status asthmaticus].

Levomepromazine reduces histamine-induced bronchial hyperresponsiveness in asthmatics without significant sedation. We present two patients with acute asthma refractory to conventional therapy, who were treated with inhalation of 2.5 mg levomepromazine. Until controlled studies have been done, we suggest that inhalation of levomepromazine be restricted to patients with asthma refractory to conventional therapy.
