Pharmacological action
Diuretic group of carbonic anhydrase inhibitors. It causes a slight diuretic effect. It inhibits the enzyme carbonic anhydrase in the proximal convoluted tubules of the nephron, It increases the urinary excretion of sodium ions, Potassium, bicarbonate, It does not affect the excretion of chloride ions; It causes an increase in urine pH. It violates the acid-base balance (metabolic acidosis). Inhibition of carbonic anhydrase of ciliary body reduces the secretion of aqueous humor and reduce intraocular pressure. Inhibition of carbonic anhydrase activity in the brain causes the anticonvulsant activity of the drug.
Duration of action – to 12 no.
Pharmacokinetics
Absorption
After oral acetazolamide is well absorbed from the gastrointestinal tract. After receiving Diamox® dose 500 mg Cmax the active substance is 12-27 ug / ml achieved after 1-3 no. Determine the concentration of acetazolamide in plasma is maintained for 24 h after dosing.
Distribution and metabolism
Distributed mainly in erythrocytes, kidney, muscle, tissues of the eyeball and the CNS. Bound to plasma proteins to a high degree. It penetrates through the placental barrier.
Acetazolamide not biotransformed in the body.
Deduction
Excreted by the kidneys in unchanged form. About 90% the dose is excreted in the urine within 24 no.
Testimony
- Edema syndrome (mild to moderate severity, in combination with alkalosis);
- Glaucoma (primary and secondary, as well as an acute attack);
- Epilepsy (in a combination therapy);
- Acute altitude (mountain) disease.
Dosage regimen
At Edema syndrome at the beginning of the treatment drug is prescribed in a dose 250-375 mg (1-1.5 tab.) 1 time / day in the morning. The maximum diuretic effect is achieved while taking the drug every other day, or 2 days in a row, and then – a one-day break. When using Diamox® should continue treatment of circulatory failure, including cardiac glycosides, a diet with restriction of salt intake and compensate for the deficiency of potassium.
Adults at open-angle glaucoma drug administered in a single dose 250 mg (1 tab.) 1-4 times / day. Doses, exceeding 1 g, do not increase the therapeutic effect. At secondary glaucoma drug administered in a single dose 250 mg (1 tab.) every 4 no. In some patients, the therapeutic effect is shown after administration of the drug at short 250 mg 2 times / day. At acute attacks of glaucoma the drug is prescribed for 250 mg 4 times / day.
Babies at glaucoma attack Diakarʙ® administered at a dose rate of 10-15 mg / kg of body weight per day for 3-4 admission.
At epilepsy adult appoint 250-500 mg / day at one time for 3 days, on 4th day – break. Children under the age of 4 to 12 Months – 50 mg / day 1-2 admission; for children 2-3 years – 50-125 mg / day 1-2 admission; children and adolescents between the ages of 4 to 18 years – by 125-250 mg 1 time / day in the morning. With simultaneous application of Diamox® other anticonvulsant used in the early treatment 250 mg (1 tab.) 1 time / day, if necessary, gradually increasing the dose. Children should not use doses, exceeding 750 mg / day.
At mountain sickness It recommends the use of the drug at a dose of 500-1000 mg (2-4 tab.) per day; when rapid ascent – by 1000 mg / day. The daily dose is divided into several stages in equal doses. The drug should be used for 24-48 hours before climbing, and in case of the onset of symptoms – continue treatment for the following 48 h or more, if necessary.
If you missed doses should not increase the dose when the next reception.

Effects on ability to drive vehicles and management mechanisms
Diakarʙ®, especially in high doses, may cause drowsiness, fatiguability, dizziness and disorientation, so during treatment, patients should not drive vehicles and use machines, require high concentration and speed of psychomotor reactions.
Overdose
