Acetazolamide

Acetazolamide

Acetazolamide is used to prevent and reduce the symptoms of altitude sickness.

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. 2 3 4 5 Acetazolamide causes mild diuresis and increases renal excretion of bicarbonate

Bicarbonate

In inorganic chemistry, bicarbonate is an intermediate form in the deprotonation of carbonic acid. It is a polyatomic anion with the chemical formula HCO⁻₃.

, causing a mild metabolic acidosis which in turn increases respiratory rate (improving oxygenation).

Acetazolamide prevents AMS when taken before ascent; it can also help speed recovery if taken after symptoms have developed. The drug works by acidifying the blood and reducing the respiratory alkalosis associated with high elevations, thus increasing respiration and arterial oxygenation and speeding acclimatization.

What is the best medicine for altitude sickness?

Acetazolamide is a useful prophylactic for acute mountain sickness causing marked reduction in headache, nausea, vomiting, weakness, etc. Improvements correlate with increased arterial oxygen concentrations, reduction in proteinuria and peripheral oedema and other objective measures of acute mountain sickness. Evidence that Acetazolamide is beneficial for …

What medications prevent altitude sickness?

Introduction: Acute mountain sickness is the most prevalent illness related to acute exposure to high altitude, secondary to the hypobaric hypoxia effects in our body. Acetazolamide has been traditionally used for its prevention and treatment, however, there is still controversy regarding the degree of usefulness of this medication as monotherapy.

What conditions does acetazolamide treat?

Acetazolamide (AZ), a carbonic anhydrase inhibitor, is a commonly used medication for the prevention and treatment of AMS. However, there is continued debate about appropriate dosing, particularly when considering rapid and physically demanding ascents to elevations above 3,500 m by emergency medical and military personnel.

What drugs cause altitude sickness?

Acetazolamide, a potent carbonic anhydrase (CA) inhibitor, is the most commonly used and best-studied agent for the amelioration of acute mountain sickness (AMS). The actual mechanisms by which acetazolamide reduces symptoms of AMS, however, remain unclear. Traditionally, acetazolamide's efficacy has been attributed to inhibition of CA in the kidneys, resulting in …

What is the main function of acetazolamide?

Acetazolamide is used to treat glaucoma, a condition in which increased pressure in the eye can lead to gradual loss of vision. Acetazolamide decreases the pressure in the eye.Sep 15, 2017

What is the action of acetazolamide?

Mechanism of Action

Acetazolamide is a carbonic anhydrase inhibitor. That means this drug works to cause an accumulation of carbonic acid by preventing its breakdown. The result is lower blood pH (i.e., more acidic), given the increased carbonic acid, which has a reversible reaction into bicarbonate and a hydrogen ion.

How does Diamox help acclimatization?

It starts to breathe deeper and faster, getting rid of the carbon dioxide, and also taking in more oxygen. In effect, the increased oxygen speeds up the acclimatisation process. It also greatly reduces you of any symptoms of altitude sickness.Aug 8, 2010
