[Nitroglycerin also as a broncholytic]. 1981

D Radenbach, and D Oltmanns, and G Hell

0,8 mg nitroglycerin administered sublingually to 10 patients with asthma bronchiale and chronic obstructive pulmonary disease effects a reduction of airway resistance up to 21% in the second and fifth minute. Even one hour after application the oscillatory resistance (Ros) is 15% lower than at the beginning. In the same patients 0,4 mg inhaled fenoterol has a stronger effect (-30%). After intravenous administration of nitroglycerin (2,5 mg/h) over 15 minutes there is a significant decrease of the plethysmographic measured resistance (Rt) (-23%), an increase of the vital capacity and a decrease of the residual volume. Side effects are a small reduction of pO2 and blood pressure and an increase of heart rate. Orthostatic disturbances may occur. The venous lactate concentration does not change. The investigation shows that patients with obstructive airway disease may benefit from the application of nitroglycerin.

D001249	Asthma	A form of bronchial disorder with three distinct components: airway hyper-responsiveness (RESPIRATORY HYPERSENSITIVITY), airway INFLAMMATION, and intermittent AIRWAY OBSTRUCTION. It is characterized by spasmodic contraction of airway smooth muscle, WHEEZING, and dyspnea (DYSPNEA, PAROXYSMAL).	Asthma, Bronchial,Bronchial Asthma,Asthmas
D014655	Vascular Resistance	The force that opposes the flow of BLOOD through a vascular bed. It is equal to the difference in BLOOD PRESSURE across the vascular bed divided by the CARDIAC OUTPUT.
