Instructions for the use of Diacarb tablets for high blood pressure and hypertension

Home → Information about diseases → Hydrocephalus (hypertensive-hydrocephalic syndrome of HHS)

Absolutely all people have a small amount of fluid in the cranial cavity that washes the brain. This liquid is called “liquor”. Liquor is constantly produced and absorbed (renewed). If a person produces more cerebrospinal fluid than is absorbed, it begins to accumulate in the cranial cavity, and intracranial pressure increases. Excess fluid begins to put pressure on the brain, causing various disruptions to its functioning. This is called hydrocephalus (increased intracranial pressure, hypertensive-hydrocephalic syndrome or “dropsy of the brain”).

Pharmacological action, pharmacodynamics and pharmacokinetics

The main therapeutic effects of the drug:

• Decongestant.
• Diuretic.

The drug inhibits the enzyme carbonic anhydrase, which affects water and sodium metabolism in the body. As a result, Diacarb helps eliminate edema of various origins, relieve an attack of acute glaucoma and compensate for the manifestations of a number of other conditions.

By participating in water-salt metabolism, the drug does not affect pH and does not disturb the acid-base balance. The duration of action is no more than 12 hours.

The maximum concentration of Diacarb is achieved in the blood 2 hours after its administration. It has a high ability to bind to protein structures of blood plasma. Able to overcome the placental barrier.

The drug is not metabolized in the body and is excreted in its original form by the kidneys within 24 hours.

Diagnosis of brain diseases in infants

Unfortunately, many mothers are faced with such troubles as difficult childbirth, prolonged toxicosis, as well as a number of unwanted complications during pregnancy, which are directly related to poor oxygen supply to the child. The result of prolonged oxygen deficiency is disturbances in the functioning of the baby’s brain cells.

Such disruptions lead to intense production of cerebrospinal fluid, the excess of which puts strong pressure on the brain. A severe headache appears, the baby becomes capricious, constantly cries and cannot sleep.

Only a doctor can identify intracranial pressure in a baby and, in accordance with the diagnosis, prescribe effective treatment. An open fontanel in children allows you to do an ultrasound of the brain for a more accurate study. Most often, in such individual cases, specialists prescribe Diacarb and Asparkam for treatment for infants . The reviews of doctor Komarovsky, in this case, are clear. He states that Diacarb is an excellent diuretic that reduces the formation of cerebrospinal fluid. Excess moisture is intensively washed out of the body along with potassium, which can be replenished with Asparkam.

Indications and contraindications

The following is a list of indications for the use of Diacarb:

• Edema of any origin (with mild or moderate severity).
• Acute attack of primary glaucoma.
• Epilepsy (as part of complex treatment of the disease).
• Pathology of the respiratory system, characterized by the accumulation of carbon dioxide and bicarbonate compounds in the blood plasma.
• Mountain sickness.

The drug is strictly prohibited for use in the following conditions:

• Individual intolerance to one or more components of the drug.
• Acidosis.
• Diabetes mellitus type 1 and 2.
• Addison's disease.
• Acute or chronic liver and kidney failure.
• Pregnancy.
• Lactation.
• Decreased potassium concentration in the blood.

Interaction with other drugs

This drug is characterized by interactions with other drugs, which requires caution when prescribing complex treatment. If you are already taking any medication, your doctor should know about it.

1. "Diacarb" has the ability to enhance the effect of certain medications. These include Ephedrine, anticoagulants, hypoglycemic drugs, folic acid antagonists.
2. The concentration of phenytoin, muscle relaxants, and carbamazepine increases in the blood.
3. Diacarb increases the side effects of taking Amphetamine, Atropine and Quinidine.
4. The toxic effects of taking cardiac glycosides, Ephedrine, Carbamazepine, and non-depolarizing muscle relaxants increase.
5. The simultaneous use of “Diacarb” and “Aminophylline”, “Theophylline” enhances the diuretic effect that the drug of interest to us has.
6. A decrease in the diuretic effect is observed with the combination of Diacarb and ammonium chloride.
7. A decrease in intraocular pressure is possible with the combination of Diacarb and anticholinergics, beta-blockers.
8. The most dangerous is the combination of Diacarb and Aspirin (acetylsalicylic acid), especially with a high dosage of the latter drug. This combination can lead to anorexia, lethargy, tachypnea and even put a person into a coma.

Side effects and clinical manifestations of overdose

Short-term use of Diacarb can provoke the development of hypokalemia, paresthesia and limb cramps, muscle weakness, acidosis, visual and auditory disturbances, appetite disorders, itching, and an allergic reaction such as urticaria.

Long-term treatment with the drug causes drowsiness, dyspeptic syndrome, hemolytic anemia, leukopenia and agranulocytosis in some patients.

Overdose symptoms are similar to adverse reactions. Treatment is symptomatic. Immediate discontinuation of the drug and contact a doctor is necessary.

Diacarb 250 mg No. 30 tablet.

Instructions for medical use of the drug DIAKARB Trade name Diakarb International nonproprietary name Acetazolamide Dosage form Tablets 250 mg Composition One tablet contains the active substance: acetazolamide 250 mg excipients: microcrystalline cellulose, povidone, colloidal silicon dioxide, croscarmellose sodium, magnesium stearate. Description Tablets are white, round, biconvex. Pharmacotherapeutic group Drugs for the treatment of eye diseases. Antiglaucoma drugs and miotics. Carbonic anhydrase inhibitors. Acetazolamide. ATC code S01EC01 Pharmacological properties Pharmacokinetics Acetazolamide is well absorbed from the gastrointestinal tract. After oral administration at a dose of 500 mg, the maximum concentration (12-27 mcg/ml) is reached within 1-3 hours. In minimal concentrations it is retained in the blood for 24 hours from the moment of administration. Acetazolamide penetrates the placental barrier and passes into breast milk in small quantities. Does not accumulate in tissues and is not metabolized in the body. It is excreted unchanged by the kidneys. After oral administration, about 90% of the dose taken is excreted in the urine within 24 hours. Pharmacodynamics Acetazolamide is a potent carbonic anhydrase inhibitor with weak diuretic activity. The mechanism of action is associated with inhibition of the release of Na+ and H+ ions in the carbonic acid molecule. Inhibition of carbonic anhydrase activity by acetazolamide suppresses the synthesis of carbonic acid in the proximal tubule of the nephron. The lack of carbonic acid, which is a source of H+ ions necessary for replacement with Na+ ions, increases the excretion of sodium and water by the kidneys. As a result of the release of large amounts of sodium in the distal part of the nephron, caused by acetazolamide, the replacement of Na+ ions with K+ ions increases, which leads to large losses of potassium and the development of hypokalemia. Acetazolamide increases bicarbonate excretion, which can lead to the development of metabolic acidosis. Acetazolamide causes the excretion of phosphates, magnesium, and calcium in the urine, which can also lead to metabolic disorders. After 3 days from the start of use, acetazolamide loses its diuretic properties. After a break in treatment for several days, newly prescribed acetazolamide resumes its diuretic effect due to the restoration of normal carbonic anhydrase activity. The extrarenal action of acetazolamide is used to treat glaucoma. Inhibition of carbonic anhydrase of the ciliary body reduces the secretion of aqueous humor in the anterior chamber of the eye, which lowers intraocular pressure. The drug is used as an adjuvant in the treatment of epilepsy. Inhibition of carbonic anhydrase in nerve cells of the brain inhibits pathological excitability. Acetazolamide is used to treat CSF leaks and intracranial hypertension. The drug suppresses the activity of carbonic anhydrase in the brain, in particular in the ventricular plexuses, with a decrease in the production of cerebrospinal fluid. Acetazolamide changes the acid-base state towards metabolic acidosis, which is used to treat respiratory disorders, including central sleep apnea. Indications for use - edema syndrome, including heart failure, edema caused by drugs and (mild and moderate severity, in combination with alkalosis) - chronic open-angle glaucoma, secondary glaucoma, closed-angle glaucoma (to reduce intraocular pressure during short-term preoperative treatment and before ophthalmological procedures , capable of triggering an acute attack of angle-closure glaucoma) - epilepsy (in combination with other anticonvulsants) with petit mal seizures in children and grand mal seizures in adults, with mixed forms - increased intracranial pressure (benign intracranial hypertension, intracranial hypertension after ventricular bypass). Method of administration and dosage The drug is taken orally. If you miss a dose of the drug, do not increase the dose at the next dose. Edema syndrome The initial dose of the drug is 250 - 375 mg (1 - 1½ tablets) 1 time per day in the morning. If the patient's edema does not improve after the initial dose, increasing the dose is not recommended. The maximum diuretic effect is achieved when taking the drug every other day or two days in a row, then a one-day break. In the treatment of heart failure, Diacarb is prescribed against the background of conventional therapy (for example, the administration of cardiac glycosides, potassium supplements, a diet with a reduced sodium content). Glaucoma The dose of the drug should be determined individually in accordance with the value of intraocular pressure. Open-angle glaucoma: 250 mg (1 tablet) 1 - 4 times a day. Doses above 1000 mg (4 tablets) do not increase the therapeutic effect. Secondary glaucoma: 250 mg (1 tablet) every 4 hours. In some patients, the therapeutic effect appears after a dose of 250 mg (1 tablet) 2 times a day (with short-term therapy). Epilepsy Dosage for adults: 250 – 500 mg/day in one dose for 3 days, break on the 4th day. When using acetazolamide simultaneously with other anticonvulsants, at the beginning of treatment, use 250 mg (1 tablet) 1 time per day, gradually increasing the dose if necessary. Dosages in children: 2 – 3 years: 50 – 125 mg/day in 1 – 2 doses; 4 – 18 years: 125 – 250 mg once in the morning. In children, doses higher than 750 mg per day should not be used. Intracranial hypertension It is recommended to use Diacarb at a dose of 250 mg (1 tablet) per day or 125 -250 mg (1/2 - 1 tablet) every 8 -12 hours. The maximum therapeutic effect is achieved when taking a dose of 750 mg (3 tablets) per day in equal doses. If repeated lumbar punctures are ineffective, it is possible to use the drug at a dosage of 500 mg 3 times a day. Side effects - paresthesia, hearing loss or tinnitus, drowsiness and disorientation, flaccid paralysis, photophobia - loss of appetite, nausea, vomiting, diarrhea, taste disturbance, thirst, diarrhea, polyuria, melena - metabolic acidosis and electrolyte imbalance - temporary myopia - urticaria, anaphylaxis, anaphylactic shock - hepatic colic, hepatitis, cholestatic jaundice, liver failure up to fulminant liver necrosis - renal colic, hepatic and renal failure - crystalluria, nephrolithiasis, urolithiasis, hematuria, glycosuria - elevated temperature - headache, dizziness , fatigue, irritability, depression, decreased libido, drowsiness - hearing loss and ringing in the ears - hematuria, glycosuria, agranulocytosis, thrombocytopenia, leukopenia and aplastic anemia, platelet purpura, bone marrow failure, pancytopenia, rash in the form of erythema multiforme - Stevens syndrome - Johnson, Lyell's syndrome. Contraindications - hypersensitivity to the components of the drug or to sulfonamides - with reduced levels of sodium and potassium in the blood serum - impaired liver and kidney function - adrenal insufficiency - hyperchloremic acidosis - chronic decompensated angle-closure glaucoma (in long-term therapy) - urolithiasis - pregnancy and lactation Drug interactions Acetazolamide may enhance the effects of folic acid antagonists, hypoglycemic agents and oral anticoagulants. The simultaneous use of acetazolamide and acetylsalicylic acid can cause severe acidosis and increase toxic symptoms from the central nervous system. During concomitant use of digitalis glycosides or drugs that increase blood pressure, it is necessary to modify the dosage of acetazolamide. Acetazolamide alters the metabolism of phenytoin, increasing its serum concentration. Severe osteomalacia has been observed in several patients taking acetazolamide concomitantly with certain anticonvulsants (phenytoin, primidone). Concomitant use of acetazolamide with amphetamines, atropine or quinidine may increase their side effects. Acetazolamide may increase or decrease blood glucose concentrations, which should be taken into account when treating diabetes mellitus. Dosage adjustments to insulin or oral hypoglycemic agents may be necessary. Acetazolamide increases the excretion of lithium and may reduce its effect. Acetazolamide may increase plasma concentrations of carbamazepine and cyclosporine. Acetazolamide may reduce the antiseptic effect of methenamine in urology. The simultaneous administration of acetazolamide and sodium bicarbonate increases the risk of kidney stones. Special instructions The drug can cause acidosis, so it should be used with caution in patients with pulmonary embolism and emphysema. The drug alkalizes urine. Acetazolamide should be used cautiously in patients with diabetes mellitus due to the increased risk of hyperglycemia. Increasing the dose does not increase urine output, but may increase the incidence of drowsiness and/or paresthesia. Special precautions are recommended when planning long-term therapy with acetazolamide. The patient should be warned to consult a doctor if any unusual skin rash appears. It is recommended to monitor blood and platelet counts at the beginning of treatment and regularly during treatment, as well as regularly monitor water-electrolyte and acid-base balance. If there is a sharp decrease in the number of formed elements of blood cells or the appearance of toxic skin manifestations, it is necessary to immediately stop therapy with acetazolamide. The behavior of patients taking acetazolamide should be monitored due to the possibility of depressive episodes with suicidal thoughts. Caution should be exercised in elderly patients due to the risk of urinary tract obstruction. Features of the effect of the drug on the ability to drive vehicles and maintain moving mechanisms While taking the drug, patients should not drive vehicles or work with mechanisms that require increased concentration and speed of psychomotor reactions. Overdose Symptoms: increased symptoms of side effects. Treatment: symptomatic. In case of acidosis, bicarbonates are used. Hemodialysis removes acetazolamide from the body.

Instructions for use Diacarb

The daily dosage and treatment regimen may vary. Features of admission depend on the presence of concomitant diseases, the age of the patient, as well as the type and severity of the underlying pathology.

For mild and moderate swelling, you should take 250 to 400 mg of the drug per day once.

For the treatment of an acute attack of glaucoma, adult patients are prescribed 250 milligrams of Diacarb every 4 hours. For pediatric patients, the dosage is calculated at 10-15 mg per kilogram of weight.

To prevent mountain sickness, it is recommended to take 500 mg of the drug 1-2 days before and during the ascent.

For patients with epilepsy, Diacarb is prescribed in a dosage of 250 to 500 mg per day for three days.

Prescription of Asparkam and Diacarb for infants

The choice of Asparkam dosage for an infant depends on many factors, so consultation with a doctor is required.
If Asparkam and Diacarb were prescribed to an infant, then their dosage, method of administration, time and frequency of doses should be determined by a qualified doctor, based on the individual case of the disease.

The dosage of Diacarb and Asparkam for infants, according to Komarovsky, depends on the following factors:

• Child's weight.
• The amount of cerebrospinal fluid.
• General background of the baby's health.
• The complexity of the disease.

Usually, babies under 12 months are prescribed a quarter of a Diacarb tablet once a day, and Asparkam in three doses a day, the dosage of which must be determined by a doctor. The tablets must be crushed to a powder and diluted with a few drops of water and poured into the child’s mouth. After taking it, it is recommended to put the baby to the breast to remove the bitter taste of the tablets.

For hypokalemia (lack of potassium in the baby’s blood), doctors prescribe Asparkam intravenously. At the mother's choice, this can be a drip method or a jet injection.

To avoid overdose, the drug is diluted with a 5% glucose solution and administered very slowly.

Reviews about the medication

Reviews from patients and doctors about the drug Diacarb are very different, both positive and negative.

Most patients note the high effectiveness of the drug, as well as its affordable cost.

Some patients speak negatively about Diakarb. For some it did not help at all, but for others it caused undesirable reactions, due to which they had to stop taking the drug. Most often, patients experience severe muscle weakness and cramps as a result of hypokalemia.

On thematic forums, the question often arises about the possibility of treatment with Diacarb during pregnancy and lactation. Currently, medical professionals do not prescribe it to expectant and nursing mothers, since there is no reliable data on the safety of its use in this category of patients.

What is Hypertension-hydrocephalic syndrome (HHS)?

Hypertensive-hydrocephalic syndrome (HHS) is caused by excessive accumulation of cerebrospinal fluid (CSF) in the ventricles of the brain and under the meninges, resulting from obstruction of outflow, excessive formation and impaired reabsorption of cerebrospinal fluid. This is one of the most common syndromic diagnoses in pediatric neurology, especially in young children with perinatal encephalopathy (PEP). It should be noted that the term “hypertensive-hydrocephalic syndrome” is a concept used exclusively in Russia. The causes of HGS can be: unfavorable course of pregnancy and childbirth, hypoxic-ischemic brain damage, deep prematurity, intracranial hemorrhage and intrauterine infections, congenital malformations of the brain, neuroinfections. Research methods to judge the level of cerebrospinal fluid pressure are very limited. Currently, the only reliable and relatively accessible of them is to perform a lumbar puncture of cerebrospinal fluid (CSF) to measure CSF pressure, which is a diagnostic criterion for this pathology. HGS can be either one of the manifestations of hydrocephalus or many other neurological diseases. The diagnostic criteria for HGS include clinical symptoms that indirectly indicate an increase in cerebrospinal fluid pressure and dilation of the ventricles of the brain.

What is the prevalence of hydrocephalus? According to official statistics, up to 70% of newly born children suffer from an obvious (hydrocephalus) or latent form (hypertensive-hydrocephalic syndrome) of this disease.

What is the reason for the widespread incidence of hydrocephalus?

• Weakness of the nervous system of children born from parents who grew up in environmentally unfavorable conditions.
• A large number of “saved” premature babies.
• Frequent use of surgical delivery, which also contributes to the development of hydrocephalus.
• A busy schedule of vaccinations up to 1 year of age contributes to the exacerbation of latent hypertensive-hydrocephalic syndrome.

Early diagnosis (ultrasound, electropuncture) also helps to identify hidden forms of the disease hydrocephalus of the brain. There are many more reasons that can be found. But the fact remains: it is necessary to identify and treat hydrocephalus without waiting for exacerbations of the disease and complications.

What are the manifestations of hydrocephalus? In children under 1 year of age: increased excitability, “unreasonable” crying, sleep disturbance, frequent regurgitation, throwing the head back in sleep, increased muscle tone (hands held in fists, legs resting on toes and crossed), weak support with legs, lack of step reflex, delayed motor and mental development. In preschool children: hypermobility, aggressiveness, hysterical manifestations, stuttering, enuresis, strabismus, frequent colds, delayed psycho-speech development (poor vocabulary, impaired diction, difficulty constructing complex sentences). In schoolchildren: nosebleeds and headaches, memory and concentration are reduced, disinhibition and neuroticism are noted, learning school material is difficult: they complete tasks slowly, make a large number of mistakes, their hands get tired quickly, their handwriting is not even, they read slowly and poorly assimilate the material they read, find it difficult to write a competent story.

What are the worst complications of hydrocephalus? CONVISIONS, CEREBRAL PALSY, MORTONITY.

What factors cause exacerbation of hydrocephalus? Any stress on the body (viral infections, stress, mental and physical fatigue, concussion, vaccinations) can lead to an exacerbation of increased intracranial pressure - especially a combination of these. For example: studying at the gymnasium + flu + stress can lead to exacerbation of hydrocephalus, headaches and a decrease in academic performance and aggressiveness.

What to do if your child has any manifestations of hydrocephalus? Promptly seek advice from the children's department of neurology and reflexology at Reatsentr to clarify whether the child needs to be examined and treated.

Types of hydrocephalus

There are several variants of the disease depending on the cause of occurrence and localization. By origin, there is a congenital form, which develops as a result of problems suffered by the baby in the prenatal state, and an acquired form, provoked after birth by external factors (injuries, infections).

According to the type of location, they are distinguished:

• external hydrocephalus, when in a child cerebrospinal fluid accumulates mainly in the space under the membranes of the brain;
• internal form, in which cerebrospinal fluid flows into the ventricles of the brain, causing them to expand;
• mixed or general hydrocephalus, which is characterized by a combination of external and internal forms of the disease.

There are also open (communicating) and closed (obstructive) types of pathology: in the first case, the communication between the ventricles and the subarachnoid space is not broken, in the second it is absent. According to the speed of flow, acute, subacute and chronic dropsy of the brain are distinguished.
