Acetazolamide is an inhibitor of carbonic anhydrase. It is used for glaucoma, epilepsy (rarely), idiopathic intracranial hypertension, and altitude sickness. For the reduction of intraocular pressure (IOP), acetazolamide inactivates carbonic anhydrase and interferes with the sodium pump, which decreases aqueous humor formation and thus lowers IOP.
Examples include metolazone, chlorthalidone, and indapamide. [1] References This page was last edited on 4 May 2022, at 02:01 (UTC). Text is available under ...
Metolazone is a thiazide-like diuretic marketed under the brand names Zytanix, Metoz, Zaroxolyn, and Mykrox. It is primarily used to treat congestive heart failure and high blood pressure . Metolazone indirectly decreases the amount of water reabsorbed into the bloodstream by the kidney , so that blood volume decreases and urine volume increases.
Acetazolamide, sold under the trade name Diamox among others, is a medication used to treat glaucoma, epilepsy, acute mountain sickness, periodic paralysis, idiopathic intracranial hypertension (raised brain pressure of unclear cause), heart failure and to alkalinize urine.
Some diuretics, such as acetazolamide, help to make the urine more alkaline, and are helpful in increasing excretion of substances such as aspirin in cases of overdose or poisoning. Diuretics are sometimes abused by people with an eating disorder, especially people with bulimia nervosa, with the goal of losing weight. [citation needed]
Loop diuretics are 90% bonded to proteins and are secreted into the proximal convoluted tubule through organic anion transporter 1 (OAT-1), OAT-2, and ABCC4.Loop diuretics act on the Na +-K +-2Cl − symporter (NKCC2) in the thick ascending limb of the loop of Henle to inhibit sodium, chloride and potassium reabsorption.
Structural formula of the potassium-sparing diuretics. Click to enlarge. Potassium-sparing diuretics or antikaliuretics [1] refer to drugs that cause diuresis without causing potassium loss in the urine. [2]
In juvenile myoclonic epilepsy, it is a second-line therapy, reserved for when the valproates or lamotrigine do not work and when the other second-line therapy, acetazolamide, does not work. [14] The usual dose for seizure disorder is titrated from 100-125 mg/day up to a maintenance dose of 750-1,500 mg/day (maximum daily dosage is 2 g).
