Acetazolamide is also used for the treatment of acute mountain sickness. In the prevention or treatment of mountain sickness, acetazolamide inhibits the ability of the kidneys to reabsorb bicarbonate, the conjugate base of carbonic acid. Increasing the amount of bicarbonate excreted in the urine leads to acidification of the blood. [12]
Acetazolamide can be taken before symptoms appear as a preventive measure at a dose of 125 mg twice daily. The Everest Base Camp Medical Centre cautions against its routine use as a substitute for a reasonable ascent schedule, except where rapid ascent is forced by flying into high altitude locations or due to terrain considerations.

CMS was first described in 1925 by Carlos Monge Medrano, a Peruvian doctor who specialised in diseases of high altitude. [3] While acute mountain sickness is experienced shortly after ascent to high altitude, chronic mountain sickness may develop only after many years of living at high altitude. In medicine, high altitude is defined as over ...
Acetazolamide is an inhibitor of carbonic anhydrase.It is used for glaucoma, epilepsy (rarely), idiopathic intracranial hypertension, and altitude sickness. For the reduction of intraocular pressure (IOP), acetazolamide inactivates carbonic anhydrase and interferes with the sodium pump, which decreases aqueous humor formation and thus lowers IOP.
Additional medications that are being considered for prevention but require further research to determine efficacy and treatment guidelines include acetazolamide, salmeterol, tadalafil (and other PDE5 inhibitors), and dexamethasone. [15] [3] [17] Acetazolamide has proven to be clinically effective, but formal studies are lacking. Salmeterol is ...
High-altitude cerebral edema (HACE) is a medical condition in which the brain swells with fluid because of the physiological effects of traveling to a high altitude. It generally appears in patients who have acute mountain sickness and involves disorientation, lethargy, and nausea among other symptoms.
Safe treatment shows Alzheimer’s potential. One of the challenges of treating Alzheimer’s is finding therapeutics that can cross the blood-brain barrier and get into the brain. Xenon gas can ...
Very high altitude = 3,500–5,500 metres (11,500–18,000 ft) Extreme altitude = above 5,500 metres (18,000 ft) Travel to each of these altitude regions can lead to medical problems, from the mild symptoms of acute mountain sickness to the potentially fatal high-altitude pulmonary edema and high-altitude cerebral edema .
