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]
A study by the Denali Medical Research Project concluded: "In established cases of acute mountain sickness, treatment with acetazolamide relieves symptoms, improves arterial oxygenation, and prevents further impairment of pulmonary gas exchange." [38] The folk remedy for altitude sickness in Ecuador, Peru and Bolivia is a tea made from the coca ...
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 ...
People who develop acute mountain sickness can sometimes be identified before the onset of symptoms by changes in fluid balance hormones regulating salt and water metabolism. People who are predisposed to develop high-altitude pulmonary edema may present a reduction in urine production before respiratory symptoms become apparent. [15]
Chronic mountain sickness (CMS) is a disease in which the proportion of blood volume that is occupied by red blood cells increases (polycythaemia) and there is an abnormally low level of oxygen in the blood . CMS typically develops after extended time living at high altitude (over 2,500 metres (8,200 ft)).
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.
They show a sustained increase in cerebral blood flow, lower hemoglobin concentration, and less susceptibility to chronic mountain sickness than other populations due to their longer history of high-altitude habitation. [33] [34] With the proper physical preparation, individuals can develop short-term tolerance to high-altitude conditions.
