Ibuprofen vs Acetaminophen in the Prevention of Acute Mountain Sickness: A Double Blind, Randomized Controlled Trial
Abstract
AMS (acute mountain sickness) affects those who ascend too high (\>2000m) too fast. Acetazolamide is an effective drug for the prevention of AMS where proper acclimatization with gradual ascent may not be an option. AMS presents with headache and other non-specific symptoms such as nausea, tiredness, and dizziness. Because of the side effects of acetazolamide such as a tingling sensation, other drugs have been investigated to see if they will prevent AMS. Ibuprofen has recently been shown to prevent AMS. In this present study the investigators want to see if acetaminophen can also prevent AMS as acetaminophen unlike ibuprofen does not have gastric side effects. Second, because acetaminophen has much less anti-inflammatory component than ibuprofen, it may also provide some insight into the pathophysiology of AMS if acetaminophen were found to be effective in the prevention of AMS.
Conditions: Acute Mountain Sickness, Blood Oxygen Saturation, Headache.
Primary outcome: Diagnosis of Acute Mountain Sickness (AMS).
Enrollment: 288 participants.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 288 participants or records.
