How it works

From the US prescribing label for the same active substance (Methazolamide). It describes the substance, not this exact product.

Methazolamide is a potent inhibitor of carbonic anhydrase.

Methazolamide is well absorbed from the gastrointestinal tract.

The shape is a standard model drawn from the two times above, not a measurement. How fast a medicine acts and wears off also depends on the dose, the form and the person.

Safety of the active substance

From the US prescribing label for the same active substance (Methazolamide). It describes the substance, not this exact product.

Must not be used by
  • Methazolamide therapy is contraindicated in situations in which sodium and/or potassium serum levels are depressed, in cases of marked kidney or liver disease or dysfunction, in adrenal gland failure, and in hyperchloremic acidosis.
  • In patients with cirrhosis, use may precipitate the development of hepatic encephalopathy.
  • Long-term administration of methazolamide is contraindicated in patients with angle-closure glaucoma, since organic closure of the angle may occur in spite of lowered intraocular pressure.
