The invention discloses a novel application of
sodium sulfite (Na2SO3), that is, an application in preparing medicines, health products, functional drinks or
functional food for preventing hypoxia-induced injury and / or diseases related to
ischemia-hypoxia. According to the invention, by using Na2SO3 as an
active component in preparing medicines, health products, functional drinks or
functional food for preventing hypoxia-induced injury and / or diseases related to
ischemia-hypoxia, the body can be in a hypoxia (such as
high altitude hypoxia, mine hypoxia, and the like ) preconditioning state, thus the purpose of preventing hypoxia-induced injury and / or diseases related to
ischemia-hypoxia (such as high altitude
pulmonary edema, high altitude
cerebral edema, cerebral ischemia,
cardiac ischemia,
respiratory distress, and the like) can be achieved. The medicines disclosed herein have the following advantages: 1) obvious
curative effect; 2) no toxic and
side effect, and high safety; 3) low price of Na2SO3; and 4) convenience in
drug use (convenience in carrying and taking).
