How carbonic anhydrase inhibitor work
These block the enzyme carbonic anhydrase, which normally helps the body recycle bicarbonate. In the kidneys this flushes more bicarbonate, sodium, and water into the urine, and in the eye it cuts production of the fluid that builds up pressure, which is why they treat conditions like glaucoma and altitude sickness.
