Efficacy of low-dose acetazolamide for the prophylaxis of acute mountain sickness. Richalet JP, Rivera M, Bouchet P, Chirinos E, Onnen I, Petitjean O, Bienvenu A, Lasne F, Moutereau S, León-Velarde F. Am J Respir Crit Care Med. Basnyat B, Gertsch JH, Holck PS, et al. The study objective was to determine whether acetazolamide is effective in prophylaxis of acute mountain sickness (AMS) at moderate altitude in ambulatory travelers not undergoing vigorous exercise. Traditionally, acetazolamide's efficacy has been attributed to inhibition of CA in the kidneys, resulting in bicarbonaturia and metabolic acidosis. The physiologic basis of high-altitude disease. It is estimated that more than 100 million people per year travel to the hypoxic environments found at altitudes above 2500 m,1 and at least 10% to 20% of unacclimatised individuals develop acute mountain sickness at this height.2 Acclimatisation to altitude involves multiple physiological changes, occurring over days to weeks, which enable individuals to function better in these hypoxic environments.

Acetazolamide 125 mg BD is not significantly different from 375 mg BD in the prevention of acute mountain sickness: the prophylactic acetazolamide dosage comparison for efficacy trial. 2020 Sep;30(5):e2136. The information on the effects of acetazolamide for the treatment for acute mountain sickness is based on two randomized trials that included 25 patients. However, the following treatments have been used when the patient's location and circumstances permit: 1981 Aug 8;283(6288):396-7. Accessed 9/25/2020. HHS If rapid ascent is undertaken and acetaZOLAMIDE is used, it should be noted that such use does not obviate the need for prompt descent if severe forms of high altitude sickness occur.

Studies performed on both animals and humans, however, have shown that this explanation is unsatisfactory and that the efficacy of acetazolamide in the context of AMS is likely due to a multitude of effects. Acute mountain sickness is the most prevalent illness related to acute exposure to high altitude, secondary to the hypobaric hypoxia effects in our body. 2014;75:361-86. doi: 10.1007/978-94-007-7359-2_18. Acetazolamide Tablets are also indicated for the prevention or amelioration of symptoms associated with acute mountain sickness in climbers attempting rapid ascent and in those who are very susceptible to acute mountain sickness despite gradual ascent.

Acetazolamide can help to prevent acute mountain sickness developing and has fewer side effects than alternative drugs such as dexamethasone, which can mask symptoms and therefore carries greater risks.
