Carbonic anhydrase inhibitors are a class of medications that block the action of the enzyme carbonic anhydrase. This enzyme plays a crucial role in regulating the balance of carbon dioxide and bicarbonate in the body, which is important for maintaining proper pH levels in blood and tissues. By inhibiting this enzyme, these drugs can help reduce the production of bicarbonate and promote the excretion of excess fluid. These inhibitors are commonly used to treat conditions such as glaucoma, epilepsy, and altitude sickness. They can also be beneficial in managing certain types of edema and heart failure. Overall, carbonic anhydrase inhibitors help improve various physiological processes by altering the acid-base balance in the body.
