    Pharmacotherapeutic group:antimicrobial agent, nitrofuran
    ATX: & nbsp

    D.08.A.F   Nitrofuran derivatives

    J.01.X.E   Nitrofuran derivatives

    Pharmacodynamics:

    A broad-spectrum antimicrobial agent belonging to the group of nitrofurans. Resistance to Furamag® develops slowly and does not reach a high degree. Active against gram-positive and gram-negative microbes, pathogenic strains Staphylococcus spp. and other microorganisms resistant to antibiotics. Effective against gram-positive cocci (strepto-, staphylococcus), gram-negative rods (Escherichia coli, Salmonella, Shigella, Proteus, Klebsiella, enterobacteria), protozoa (lamblia). In relation to staphylococci, E.coli, Aerobacter aero genes, Bad. Citrovorum, Proteus mirabilis, Proteus morganii Furamag®, in comparison with other nitrofurans, is more active. Furamag® shows a higher activity towards Enterococcus faecalis, Staphylococcus spp. compared with other groups of antimicrobial drugs.

    PThe bacteriostatic concentration of most bacteria is from 1: 100,000 to 1: 200,000. The bactericidal concentration is approximately twice as large. Under the influence of nitrofurans in microorganisms, the respiratory chain and the cycle of tricarboxylic acids (Krebs cycle) are suppressed, as well as the inhibition of other biochemical processes of microorganisms, as a result of which their shell or cytoplasmic membrane is destroyed.As a result of the action of nitrofurans, microorganisms produce fewer toxins, so that an improvement in the general condition of the patient is possible even before the expressed suppression of microflora growth. Nitrofurans, unlike many other antimicrobial agents, not only do not inhibit the immune system of the body, but, on the contrary, activate it (increase the complement titre and the ability of leukocytes to phagocytose microorganisms). Nitrofurans in therapeutic doses stimulate leukopoiesis.

    Pharmacokinetics:
    Absorption occurs in the small intestine, by passive diffusion. Absorption of nitrofurans from the distal segment of the small intestine exceeds the absorption from the proximal and middle segments, respectively, 2 and 4 times (should be taken into account in the simultaneous treatment of urogenital infections and diseases of the gastrointestinal tract, including chronic enteritis). Nitrofurans are poorly absorbed in the large intestine.
    Furamag, being a mixture of potassium furosidine and magnesium hydroxycarbonate in the ratio 1: 1, with oral administration has a higher bioavailability than simple furazidine (after taking Furamag® capsule in the acidic environment of the stomach, there is no conversion of potassium furozidine to poorly soluble furazidine).
    In organism furazidine distributed evenly.Clinically important is the high content of active ingredient in lymph (delays the spread infection by lymphatic pathways). In bile, its concentration is several times higher than in serum, and in CSF it is several times lower than in serum. In saliva, the content of furazidine is 30% of its serum concentration. The concentration of furazidine in the blood and tissues is relatively small, which is due to its rapid release, while the concentration in the urine is much higher than in the blood. The maximum concentration in the blood is kept from 3 to 7 or 8 hours, in the urine furazidine is found 3-4 hours after application.

    In contrast to nitrofurantoin (furadonin), after the adoption of Furamag®, the pH of urine does not change. Four hours after taking the drug Furamag®, the concentration of furazidine in the urine is significantly higher than the concentration that is formed after taking the same dose of the drug Furagin. Kidney secretion occurs by glomerular filtration and tubular secretion (85%), partially subjected to reverse reabsorption in tubules. At low concentrations of furazidine in the urine, the filtration and secretion process predominates, at high concentrations the secretion decreases and reabsorption increases. Furazidine, being a weak acid, does not dissociate in acidic urine, undergoes intensive reabsorption, which can increase the development of systemic side effects. With alkalization of urine, excretion of furazidine is enhanced. The active substance of the preparation is slightly biotransformed (less than 10% of the administered dose), with a decrease in the excretory function of the kidneys, the intensity of metabolism increases.


    Indications:

    Infections caused by susceptible to furazidine by microorganisms: urogenital infections (acute cystitis, urethritis, pyelonephritis), skin and soft tissue infections, severe infected burns, gynecological infections. Prophylactically it is possible to apply at urological operations, a cystoscopy, a catheterization, etc.


    Contraindications:

    Hypersensitivity to nitrofuran group preparations, pregnancy and lactation period. Severe chronic renal failure. Children under 3 years (for this dosage form).

    Carefully:

    deficiency of glucose-6-phosphate dehydrogenase

    Dosing and Administration:

    The drug is taken after meals, washed down with a lot of liquid.

    Adults appoint 50-100 mg (2-4 capsules) 3 times a day.

    Children prescribe 25-50 mg (1-2 capsules) 3 times a day, but not more than 5 mg / kg of body weight per day. The course of treatment is from 7-10 days. If necessary, after a 10-15 day break, repeat the course.

    To prevent infection with urological operations, cystoscopy, catheterization, etc. the drug is prescribed: adults 50 mg once for 30 minutes before the procedure; children 25 mg once every 30 minutes before the procedure.

    If you forget to take the next dose, take the next dose at the usual time.

    Do not take a double dose to replace the missed dose.

    Side effects:

    Furamag is low in toxicity. Rarely, side effects characteristic of other nitrofurans were observed: headache, dizziness, nausea, vomiting, loss of appetite, polyneuritis, liver dysfunction, allergic reactions (skin rash, papular rashes).

    If during the period of treatment Furamag revealed side effects not specified in the instructions, then it is necessary to inform the attending physician.


    Overdose:

    In case of an overdose, symptoms of a neurotoxic nature, ataxia and tremor are observed.

    In case of poisoning, drink plenty of fluids.For relief of acute symptoms, antihistamines are used. For the prevention of neuritis, the administration of vitamins (thiamine bromide) is possible.

    Interaction:

    Do not apply Furamag® concomitantly with ristomycin, chloramphenicol, sulfonamides (increases the risk of oppression of hematopoiesis).

    During treatment it is advisable to refrain from drinking alcoholic beverages. may increase side effects.

    It is not recommended simultaneously with nitrofurans to prescribe drugs that can "acidify" urine (including ascorbic acid, calcium chloride).

    Special instructions:

    To reduce the likelihood of side effects, Furamag is washed down with plenty of fluids. When side effects occur, the drug is discontinued (toxic effects are more frequent in patients with reduced renal excretory function).
