Summary
Methazolamide is used to treat glaucoma, which is increased pressure in the eye, and certain types of fluid retention, which is when the body holds onto excess water.
Methazolamide works by inhibiting an enzyme called carbonic anhydrase, which helps reduce fluid buildup in the body. This action lowers eye pressure and reduces fluid retention.
The usual starting dose for adults is 50-100 mg taken 2-3 times daily. The maximum recommended dose is 300 mg per day. Methazolamide is taken orally, which means by mouth.
Common side effects include nausea, vomiting, and dizziness. These effects are usually mild and may go away on their own.
Methazolamide can cause electrolyte imbalances, which are changes in blood mineral levels. It's contraindicated in people with severe kidney or liver problems, which affect waste filtering organs.
Indications and Purpose
How does Methazolamide work?
Methazolamide works by inhibiting an enzyme called carbonic anhydrase, which helps reduce fluid buildup in the body. Think of it like turning off a faucet to stop water flow. By blocking this enzyme, Methazolamide decreases the production of fluid in the eye, lowering eye pressure. This action helps treat glaucoma and reduce fluid retention. The medication is effective in managing these conditions when used as directed.
Is Methazolamide effective?
