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. Current pharmacological modalities for management of novel coronavirus disease 2019 (COVID-19) and the rationale for their utilization: A review. It is used in the treatment of glaucoma, drug-induced edema, heart failure-induced edema, epilepsy and in reducing intraocular pressure after surgery. Acute mountain sickness (AMS) is a syndrome induced by hypobaric hypoxia in individuals who ascend rapidly to altitudes above 2500m and may represent an early form of high altitude cerebral edema (HACE). Hackett PH, Roach RC, Wood RA, et al.

Dexamethasone for prevention and treatment of acute mountain sickness. 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. This review summarizes the known systemic effects of acetazolamide and incorporates them into a model encompassing several factors that are likely to play a key role in the drug's efficacy. 2006;7(1):17-27. Lancet. Ann Intern Med 1992 15; 116: 461-5. Attempts to treat or stabilize the patient in situ (at altitude) are dangerous unless highly controlled and with good medical facilities. 2012 Oct 18;345:e6779.

The most important treatment if you start to develop symptoms of mild AMS is to stop your ascent and to rest at the same altitude. Would you like email updates of new search results? High-altitude headache responds to ibuprofen, and can be prevented, at least in some individuals or to some degree, by aspirin, furosemide, acetazolamide (Diamox®) before reaching high altitudes. Acetazolamide to prevent the symptoms of Khatri R, Gupta RK, Vats P, Bansal V, Yadav AK, Reddy PK, Bharadwaj A, Chaudhary P, Sharma S, Bajaj AC, Deskit P, Dass D, Baburaj TP, Singh SB, Kumar B. The actual mechanisms by which acetazolamide reduces symptoms of AMS, however, remain unclear. Acetazolamide, a potent carbonic anhydrase (CA) inhibitor, is the most commonly used and best-studied agent for the amelioration of acute mountain sickness (AMS). NOTE: We only request your email address so that the person you are recommending the page to knows that you wanted them to see it, and that it is not junk mail. The medication is effective in preventing acute mountain sickness (AMS), high altitude pulmonary edema (HAPE), and high altitude cerebral edema (HACE). Carbonic anhydrase inhibitors and high altitude illnesses. If this is not possible, or if symptoms occur despite slow ascent, acetazolamide or dexamethasone may be used for prophylaxis or treatment of acute mountain sickness. i.e., high altitude pulmonary edema (HAPE) or high-altitude cerebral edema. One possible explanation is that the diuretic effect hastens renal excretion of bicarbonate, thus producing a metabolic acidosis with respiratory stimulation, particularly during sleep [3,7,8]. The actual mechanisms by which acetazolamide reduces symptoms of AMS, however, remain unclear. The therapeutic importance of acid-base balance. Such factors include not only metabolic acidosis resulting from renal CA inhibition but also improvements in ventilation from tissue respiratory acidosis, improvements in sleep quality from carotid body CA inhibition, and effects of diuresis. However, the following treatments have been used when the patient's location and circumstances permit: Identifying the lower effective dose of acetazolamide for the prophylaxis of acute mountain sickness: systemic review and meta-analysis. Evaluating Health Impact at High Altitude in Antarctica and Effectiveness of Monitoring Oxygen Saturation. This site needs JavaScript to work properly. Dexamethasone (DMS) has been advocated for treatment of HACE; several recent studies have sought to investigate its therapeutic role in AMS. 2020 Nov 1;260:118408. doi: 10.1016/j.lfs.2020.118408.
