MEDICAL COMPOSITION FOR TREATING PATIENT ACCOMPANIED BY BRONCHOCONSTRICTION AND APPARATUS FOR INHALATION OF THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a medical composition capable of relaxing bronchoconstriction, especially constriction of bronchial smooth muscle by constituting the composition of a mixed gas containing NO gas and O2 gas obtained by mixing a specific component therewith just before inhalation by a patient. SOLUTION: This medical composition comprising NO gas and a mixed gas containing O2 is obtained by mixing, for example, a gas containing compressed NO gas in N2 gas with O2 /N2 mixed gas just before inhalation to a patient. The composition is inhaled by mammals having pulmonary vascularity contraction, asthma, etc., under one or more conditions corresponding to (a) a state of including no smoke of tobacco, (b) a state of inhaling as a mixed gas of NO gas, O2 gas and N2 gas, (c) a state of the inhaling concentration of NO gas being 1ppm, preferably 80-180ppm, (d) a state of maintaining the concentration of NO2 concentration under the safety limit (=1ppm) or (e) a state of inhaling for =3min, preferably =6min.
