Ethoxzolamide is primarily used in medical applications due to its ability to inhibit carbonic anhydrase, an enzyme involved in various physiological processes. It is commonly prescribed to treat conditions like glaucoma, as it reduces intraocular pressure by decreasing the production of aqueous humor in the eyes. Additionally, it is used as a diuretic to manage fluid retention and edema in patients with heart failure or other conditions. In some cases, it is also employed to treat altitude sickness, helping to alleviate symptoms such as headaches and nausea by promoting acclimatization. Its therapeutic effects make it a valuable compound in managing these health issues.
