The drug is occasionally used on an intermittent basis to prevent seizures in catamenial epilepsy. [10] The sulfur-containing antiseizure and antimigraine drug topiramate is a weak inhibitor of carbonic anhydrase, particularly subtypes II and IV. [11] Whether carbonic anhydrase inhibition contributes to its clinical activity is not known.
Sultiame (or sulthiame) is a sulfonamide and inhibitor of the enzyme carbonic anhydrase. It is used as an anticonvulsant and in recent studies showed promise in reducing sleep disordered breathing and other symptoms of obstructive sleep apnea (OSA).
Common side effects include eye discomfort, eye redness, taste changes, and blurry vision. [3] Serious side effects may include allergic reactions and heart failure. [3] Use is not recommended in those with asthma, a sulfonamide allergy, or a slow heart rate. [3] [7] Dorzolamide is a carbonic anhydrase inhibitor and timolol is a beta blocker. [3]
Acetazolamide is a first generation carbonic anhydrase inhibitor and it decreases the ocular fluid and osmolality in the eye to decrease intraocular pressure. [5] [6] Common side effects include numbness, ringing in the ears, loss of appetite, vomiting, and sleepiness. [2]
Topiramate selectively inhibits cytosolic (type II) and membrane-associated (type IV) forms of carbonic anhydrase. Its action on carbonic anhydrase isoenzymes may contribute to the drug's side effects, including its propensity to cause metabolic acidosis and calcium phosphate kidney stones.
Serious side effects include Steven Johnson syndrome. [3] Those allergic to sulfonamides may be allergic to dorzolamide. [3] [5] Use is not recommended in pregnancy or breastfeeding. [5] It is a carbonic anhydrase inhibitor and works by decreasing the production of aqueous humor. [3] Dorzolamide was approved for medical use in the United States ...
For example, carbonic anhydrase produces acid in the stomach lining. In the kidney, the control of bicarbonate ions influences the water content of the cell. The control of bicarbonate ions also influences the water content in the eyes. Inhibitors of carbonic anhydrase are used to treat glaucoma, the excessive build-up of water in the eyes.
Merck discontinued diclofenamide when better glaucoma drugs were developed. In 2010, Sun Pharmaceutical Industries bought the rights. [citation needed] In 2015, the F.D.A. approved it as an orphan drug, with 7-year exclusive marketing rights, for periodic paralysis, which the company estimates affects 5,000 people in the U.S. In 2016 ...
