Treatment Summary
Acetazolamide is a medication used to reduce the frequency of absence seizures. It can also be used to treat other types of seizures, like tonic-clonic, myoclonic, and atonic seizures, especially in women whose seizures are linked to their menstrual cycle. However, it may not be effective for long because some patients can become tolerant to its effects. Acetazolamide works by blocking brain carbonic anhydrase, which leads to an increased flow of chloride ions and increased inhibition in the brain.

Effectiveness
How Acetazolamide Affects Patients
Acetazolamide is a medication that helps control fluid production, treats certain types of seizures, and encourages urination when fluid builds up in the body. It is not related to mercury-based diuretics, but is instead a type of sulfonamide drug with a unique structure and effects.
How Acetazolamide works in the body
Acetazolamide helps with seizures and can also act as a diuretic. It works by inhibiting the carbonic anhydrase enzyme in the brain and kidneys. This reduces the amount of hydrogen ions present, which leads to less carbon dioxide in the lungs and more oxygen. In the kidneys, it reduces the number of hydrogen ions available for active transport, resulting in more bicarbonate, sodium, potassium, and water being excreted from the body.
When to interrupt dosage
The measure of Acetazolamide is contingent upon the diagnosed disorder, including Edema, Tonic - clonic seizures and Metabolic Alkalosis. The amount of dosage fluctuates, as per the administration technique (e.g. Injection, powder, lyophilized, for solution - Intravenous or Powder, for solution) presented in the table below.
