Diamox

Diamox Uses, Dosage, Side Effects, Food Interaction and all others data.

Diamox is a carbonic anhydrase inhibitor. This enzyme catalyzes the reversible reaction involving the hydration of carbon-di-oxide and the dehydration of carbonic acid. In the eye, this inhibitory action of Diamox decreases the secretion of aqueous humor and results in a drop in intraocular pressure, a reaction considered desirable in case of glaucoma. Inhibition of carbonic anhydrase in the central nervous system appears to retard abnormal paroxysmal and excessive discharge from central nervous system neurons. So, Diamox is also used as an adjuvant in the treatment of epilepsy.

Diamox is a potent carbonic anhydrase inhibitor, effective in the control of fluid secretion, in the treatment of certain convulsive disorders and in the promotion of diuresis in instances of abnormal fluid retention. Diamox is not a mercurial diuretic. Rather, it is a nonbacteriostatic sulfonamide possessing a chemical structure and pharmacological activity distinctly different from the bacteriostatic sulfonamides.

Uses

Open angle glaucoma, secondary glaucoma and as an adjuvant in the treatment of edema and epilepsy.

Diamox is also used to associated treatment for these conditions: Edema, Familial periodic paralysis, Grand mal Generalized tonic-clonic seizure, Metabolic Alkalosis, Open Angle Glaucoma (OAG), Other and unspecified effects of high altitude, Acute Angle closure glaucoma, Cystine renal calculi, Drug-induced edema, Nonuveitic secondary glaucoma, Salicylate intoxication, Urine alkalinization therapy

How Diamox works

The anticonvulsant activity of Diamox may depend on a direct inhibition of carbonic anhydrase in the CNS, which decreases carbon dioxide tension in the pulmonary alveoli, thus increasing arterial oxygen tension. The diuretic effect depends on the inhibition of carbonic anhydrase, causing a reduction in the availability of hydrogen ions for active transport in the renal tubule lumen. This leads to alkaline urine and an increase in the excretion of bicarbonate, sodium, potassium, and water.

Pregnancy & Breastfeeding use

There are no adequate and well controlled studies in pregnant women and neonates. So, Diamox should be used with care in those physiological conditions.

Contraindication

Diamox is contraindicated in cases of marked kidney and liver diseases or dysfunction, in situations in which sodium and or potassium blood serum levels decreased. Diamox is also contraindicated in patients with chronic noncongestive angle closure glaucoma
