Apo-Acetazolamide
Apo-Acetazolamide Uses, Dosage, Side Effects, Food Interaction and all others data.
Apo-Acetazolamide 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 Apo-Acetazolamide 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, Apo-Acetazolamide is also used as an adjuvant in the treatment of epilepsy.
Apo-Acetazolamide 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. Apo-Acetazolamide 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.
Apo-Acetazolamide 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 Apo-Acetazolamide works
The anticonvulsant activity of Apo-Acetazolamide 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, Apo-Acetazolamide should be used with care in those physiological conditions.
Contraindication
Apo-Acetazolamide is contraindicated in cases of marked kidney and liver diseases or dysfunction, in situations in which sodium and or potassium blood serum levels decreased. Apo-Acetazolamide is also contraindicated in patients with chronic noncongestive angle closure glaucoma
