What is Acetazolamide

AcetazolamideThe Generic name of this drug
Treatment SummaryAcetazolamide 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 PatientsAcetazolamide 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 bodyAcetazolamide 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.

Acetazolamide Reviews: What are patients saying about Acetazolamide?

5Patient Review
4/1/2010
Acetazolamide for Pseudotumor Cerebri
This treatment has been great for me. It's helped with my headaches and neck tension, and I've even lost 16 pounds in 2 1/2 weeks. The only downside is that soda now tastes like metal to me, but that's not really a bad thing!

Acetazolamide for Pseudotumor Cerebri
I've been taking Acetazpolamide for over two and a half years, and I couldn't be more grateful. Before this medication, I had papilloedema; now, I'm able to live my life normally. Coca-Cola still tastes great to me, too!
4Patient Review

Acetazolamide for Pseudotumor Cerebri
I had issues with constipation and rectal pain, but this medication cleared that right up. I also experienced less pain overall.
3.3Patient Review
2/3/2010
Acetazolamide for Pseudotumor Cerebri
I had some initial nausea but that went away after a little while. I still have numbness in my hands and feet, though.
3.3Patient Review
5/15/2010
Acetazolamide for Closed Angle Glaucoma
I currently take this medication twice a day, and while it has helped with some symptoms, others (like headaches) are still present. It's an improvement, but not ideal by any means.
