Acetazolamide is a medication primarily used to treat conditions like glaucoma, altitude sickness, and certain types of seizures. It works by inhibiting an enzyme called carbonic anhydrase, which helps regulate fluid balance in the body. This action leads to increased urine production and decreased pressure in the eyes. Additionally, acetazolamide can help prevent symptoms of altitude sickness by promoting the excretion of bicarbonate, which helps the body acclimatize to high altitudes. It is usually taken in tablet form and may have side effects such as tingling sensations, increased urination, and changes in taste.
