Commonly used anti-hypoxia (anti-plateau reaction) drugs include: Rhodiola rosea, Cordyceps sinensis, Sea buckthorn, Radix et Rhizoma ginseng, Astragalus, Poria, Ginseng, Tangut Cyanus, Acanthopanax, Ganoderma lucidum, etc. Acetazolamide (vincristine) is generally considered abroad as the drug of choice for the prevention and treatment of acute plateau reactions. Until 1994, acetazolamide was the only drug approved by the FDA for this indication in the United States. Glucocorticoids and theophylline can also be used to improve blood oxygen saturation and reduce the symptoms of acute altitude sickness. At present, there are many anti-hypoxia (anti-altitude reaction) drugs and health products in pharmacies or hospitals, and there is no shortage of mixed products. Here it is important to distinguish between drugs (medicines) and health products. The composition, production capacity and technical conditions of drug formulas have to be strictly examined by the relevant state departments and pass the strict examination of pharmacology, pathology and virus and years of clinical observation, and only after the relevant departments have identified and approved them, can they be put on the market. Health care products can be put on the market without going through clinical trials in hospitals, etc. Drugs have definite efficacy and indications and clear adverse reactions, while health products do not have this process and have no clear therapeutic effect, but only auxiliary regulation. The most intuitive and simple way to differentiate is that drugs have national approval numbers, i.e. “State Drug Certificate”; health products do not have “State Drug Certificate”.
