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.
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]
Carbonic anhydrase inhibitors: acetazolamide, [17] dorzolamide: Inhibits H + secretion, resultant promotion of Na + and K + excretion 2. proximal tubule: Loop diuretics: bumetanide, [17] ethacrynic acid, [17] furosemide, [17] torsemide: Inhibits the Na-K-2Cl symporter: 3. medullary thick ascending limb: Osmotic diuretics: glucose (especially in ...
Agents in common clinical use include: [1] [2] Prostaglandin analogs; Parasympathomimetic (miotic) agents, including cholinergic and anticholinesterase agents; Carbonic anhydrase inhibitors (oral and topical)
Brinzolamide is a carbonic anhydrase inhibitor (specifically, carbonic anhydrase II). Carbonic anhydrase is found primarily in erythrocytes (but also in other tissues including the eye). It exists as a number of isoenzymes, the most active of which is carbonic anhydrase II (CA-II).
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).
Methazolamide (trade name Neptazane) is a potent carbonic anhydrase inhibitor. It is indicated in the treatment of increased intraocular pressure (IOP) in chronic open-angle glaucoma and secondary glaucoma. Also it is used preoperatively in acute angle-closure (narrow-angle) glaucoma where lowering the IOP is desired before surgery.
