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

Iopar 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 Iopar 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, Iopar is also used as an adjuvant in the treatment of epilepsy.

Iopar 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. Iopar is not a mercurial diuretic. Rather, it is a nonbacteriostatic sulfonamide possessing a chemical structure and pharmacological activity distinctly different from the bacteriostatic sulfonamides.

How Iopar works

The anticonvulsant activity of Iopar 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.

Dosage

Iopar dosage

Adults : Initially 250 mg (1 tablet) 4 times daily. Dose should be adjusted later with individual need.

Children : ½ to 2 tablets in divided doses.

In intraocular pressure: 1 tablet 6 hourly. In acute condition, dose should be started with 2 tablets followed by 1 tablet 6 hourly or as directed by the physician

Pregnancy & Breastfeeding use

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

Contraindication

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