Broad spectrum antimicrobial agent, belonging to the group of nitrofurans.
Resistance to Furamagu® It progresses slowly and does not reach a high degree of.
Active against Gram-positive cocci: Streptococcus spp., Staphylococcus spp.; Gram-negative rods: Escherichia coli, Salmonella spp., Shigella spp., Proteus is wonderful, Klebsiella spp., Enterobacter spp.; protozoa: Lamblia intestinalis and other microorganisms, antibiotic resistant.
With respect to Staphylococcus spp., Escherichia coli, Aerobacter aerogenes, Leuconostoc citrovorum, Proteus is wonderful, Proteus morganii Furamag®, compared with other nitrofurans, more active.
Against most of the bacteria bacteriostatic concentration is 1:100 000 to 1:200 000. The bactericidal concentration is about 2 times.
Under the influence of nitrofurans in microorganisms, the respiratory chain and the tricarboxylic acid cycle are suppressed. (Krebs cycle), and the oppression of other biochemical processes of microorganisms, resulting in the destruction of their membrane or cytoplasmic membrane.
As a result of nitrofurans microorganisms produce less toxins, therefore the improvement of the general condition of the patient may still expressed to inhibit the growth of microflora. Nitrofurans activate the immune system: titer of complement and enhance the ability of leukocytes phagocytose microorganisms. Furazidin therapeutic doses stimulates leucopoiesis.
Absorption
After oral administration furazidin absorbed in the small intestine by passive diffusion. Suction nitrofurans from the distal segment of the small intestine than absorption from the proximal and medial segments respectively 2 and 4 times (It should be taken into account while treating urogenital infections and gastrointestinal diseases, in particular chronic enteritis). Nitrofurans are poorly absorbed from the colon.
Cmax in the blood plasma is retained by 3 to 7 or 8 no, furazidin detected in urine by 3-4 no.
It is a mixture of potassium salt and magnesium carbonate furazidina principal in the ratio 1:1, Furamag® in oral administration has a higher bioavailability, than a simple furazidin (after receiving the capsule Furamaga® in the acidic environment of the stomach does not occur in the conversion furazidina poorly soluble potassium furazidin).
Distribution
In the body is distributed evenly furazidin. Clinically important drug in high content lymph (delay the spread of infection through the lymphatic pathways). The bile concentration in several times higher, than serum, а в ликворе – в несколько раз ниже, than serum. The saliva content is furazidina 30% its concentration in serum. Furazidina concentration in the blood and tissues of a relatively small, due to its rapid release, wherein the concentration is significantly higher in the urine, than in blood.
Metabolism
Slightly biotransformiroetsa (<10%).
Deduction
Unlike nitrofurantoin (furadonina), after the adoption of Furamaga® Urine pH is not changed. Through 4 hours after ingestion furazidina concentration in urine concentration significantly exceeds that, which is formed after administration of the same dose furagin.
Excreted by the kidneys by glomerular filtration and tubular secretion (85%), partially exposed to the back of reabsorption in the tubules. At low concentrations of furazidin in the urine, the process of filtration and secretion predominates, at high concentrations, decreases the secretion and increases the reabsorption. Furazidin, Being a weak acid in acidic urine does not dissociate, Under intense reabsorption, that can enhance the development of systemic side effects. When alkaline urine excretion furazidina enhanced.
Pharmacokinetics in special clinical situations
By reducing the renal excretory function metabolic rate increases.
Infection, caused by susceptible microorganisms:
The drug is taken orally after a meal.
Adults appoint 50-100 mg 3 times / day.
Children over 3 years appoint 25-50 mg (no more 5 mg / kg body weight) 3 times / day.
A course of treatment 7-10 days. If you need to repeat the course of treatment should take a break for a 10-15 days.
To prevention of infection (incl. urological operations, cystoscopy, Catheterization) drug prescribed adult by 50 mg, children - By 25 mg dose of 30 minutes prior to the procedure.
In the event of missed doses, next dose should be taken at the usual time. Do not take double the dose to compensate the missed dose.
From the digestive system: rarely - nausea, vomiting, loss of appetite, abnormal liver function.
From the central and peripheral nervous system: seldom - a headache, dizziness, polyneuritis.
Allergic reactions: редко – кожная сыпь (incl. papular rash).
Furamag® malotoksichen.
FROM caution use in patients with deficiency of glucose-6-phosphate dehydrogenase, in the neonatal period.
Do not use this drug during pregnancy and lactation (breast-feeding).
To reduce the risk of side effects Furamag® washed down with plenty of liquid.
When the side effects of the drug should be discontinued (toxic effects often occur in patients with impaired renal excretory function).
The patient must inform the doctor about any side effects, occur during treatment with.
During treatment the patient is recommended to refrain from drinking alcoholic beverages, because side effects may be increased.
Effects on ability to drive vehicles and management mechanisms
Effects on ability to drive vehicles and management mechanisms are not noted.
Symptoms: manifestations of a neurotoxic nature, ataxia, tremor.
Treatment: should drink plenty of fluids. For the relief of acute symptoms used antihistamines (difengidramin). To prevent possible appointment of vitamins neuritis (thiamine bromide).
Do not use Furamag® at the same time ristomycin, chloramphenicol, sulьfanilamidami (It increases the risk of bone marrow suppression).
Not recommended together with nitrofurans prescribe drugs, able to acidify the urine (incl. ascorbic acid, calcium chloride).
The drug is released under the prescription.
The drug should be stored out of reach of children, dry, dark place at a temperature no higher than 25 ° C. Shelf life - 3 year.
