Carbonic anhydrase inhibitors are a class of pharmaceuticals that suppress the activity of carbonic anhydrase. Their clinical use has been established as anti- glaucoma agents, diuretics , antiepileptics , in the management of mountain sickness , gastric and duodenal ulcers , idiopathic intracranial hypertension , neurological disorders , or ...
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.
Ethoxzolamide binds and inhibits carbonic anhydrase I. Carbonic anhydrase plays an essential role in facilitating the transport of carbon dioxide and protons in the intracellular space, across biological membranes and in the layers of the extracellular space. The inhibition of this enzyme effects the balance of applicable membrane equilibrium ...
Acetazolamide is a carbonic anhydrase inhibitor, hence causing the accumulation of carbonic acid. [12] Carbonic anhydrase is an enzyme found in red blood cells and many other tissues that catalyses the following reaction: [26] H 2 CO 3 ⇌ H 2 O + CO 2. hence lowering blood pH, by means of the following reaction that carbonic acid undergoes: [27]
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 in 1994. [3] It is available as a generic medication. [5] In 2022, it was the 201st most commonly prescribed medication in the United States, with more than 2 million prescriptions. [6] [7]
While definitive sites of metabolism have not been firmly established, there are several metabolites worthy of note. N-Desethylbrinzolamide is an active metabolite of the parent compound, and thus exhibits carbonic anhydrase inhibitory activity (largely carbonic anhydrase-I, when in the presence of Brinzolamide) and also accumulates in the erythrocytes.
Adverse reactions can include superinfection, pain or burning upon application, rash, pruritus, tachypnea, or hyperventilation. Mafenide is metabolized to a carbonic anhydrase inhibitor, which could potentially result in metabolic acidosis. [4]
Zonisamide and other carbonic anhydrase inhibitors such as topiramate, furosemide, and hydrochlorothiazide have been known to interfere with amobarbital, which has led to inadequate anesthetization during the Wada test. [21] Zonisamide may also interact with other carbonic anhydrase inhibitors to increase the potential for metabolic acidosis. [5]
