Bezylpenicillin is an antibiotic group penicillinsintended for injecting administration. The drug is used to treat various infections caused by bacteria sensitive to its action, such as, for example, pneumonia, bronchitis and other severe infectious diseases of the ENT organs and respiratory tract, meningitis, syphilis, endocarditis, purulent infections, etc.Since benzylpenicillin is practically not absorbed in the digestive tract, it is injected exclusively injectable. The most often solutions of the drug are injected intramuscularly or intravenously. However, in addition, the introduction of benzylpenicillin in the spinal channel (under meningitis), under the skin or directly to the wound region.
Benzylpenicilline is an antibiotic that contains the same active substance. However, in drugs, benzylpenicillin is not in pure form, but in the form of salts. Benzylпenicillin salts are stable and can be stored, unlike a pure active substance, which quickly disintegrates. In the body of salts, benzylpenicillin is released and the action is destructive on bacteria.
Depending on whether benzylpenicillin in the form of salt is located in a dosage preparation, the varieties of benzylpenicillin are distinguished. In principle, all varieties of benzylpenicillin are the same in its spectrum of action, but differ in the duration of the effect and methods of administration. Therefore, when various diseases It is recommended to select the type of preparation that is optimally suitable for the requirements of therapy.
Currently, the following varieties of benzylпenicillin are issued:
All varieties of benzylpenicillin are produced in the only dosage form - Powder for the preparation of the solution for injections. The powder is placed in glass vials, clapped with rubber caps covered on top of aluminum dense foil. The bottles, in which the antibiotic powder are packaged, is called "penicillin" in everyday life.
Benzylpenicillin penetrates all organs and tissues, and therefore can be used to treat infectious diseases Various localization, if they are provoked sensitive to its actions by bacteria.
All varieties of benzylpenicillin are destructively affect the following types of pathogenic microorganisms:
Benzylpenicillin benzatin is optimal for the treatment of chronic infections and the prevention of various infectious complications. Therefore, drugs containing this salt should be used for long-term therapy of various chronic diseases.
With the use of benzylpenicillin in high dosages (above 20,000,000 units per day) For more than five days, it is necessary to control the concentration of blood electrolytes (potassium, calcium, sodium, chlorine), the function of the liver (asat, aloset, ukf, bilirubin, etc.) and Picture of blood (overall blood test with leukoformula).
People using benzylpenicillin may have a false-positive urine reaction on sugar.
In people suffering from diabetes, sucking the antibiotic in the blood of the muscle slow down, so the effect of the drug begins more slowly.
Since the use of benzylpenicillin can lead to the development of fungal infection, then against the background of treatment with an antibiotic, it is recommended to prevent preventive

Sodium benzylpenicillin salt for 500,000 cells 3-6 times / day.
In patients with severe degrees of hepatic and / or renal failure Preferably clarify one-time doses Or intervals between doses in creatinine clearance values.
Dosage based on creatinine clearance:
From the gearbox:occasionally marked stomatitis and glossites. Nausea, vomiting. The diarrhea resulting during the appointment of antibiotics should cause alertness with respect to pseudommbranous colitis (the possibility of the appearance of stable microorganisms or fungi) and further treatment should be specific to the microorganism of the causative agent. When superinfection appears, appropriate measures should be taken.
Allergic:proper attention should be paid by-effects, namely, anaphylaxis, urticaria, fever, articular pain, angioedema, multiform erythene and exfoliative dermatitis.
Due to bacteriology in infections caused by endotoxin-producing bacteria, such as salmonells, leptospiirs or treponema (treatment for syphilis), Yarish-Gersheimer's reaction (Jarish Hersheimer) may be observed due to bacteriology.
Hematologic:hemolytic anemia, leukopenia, thrombocytopenia or eosinophilia.
Disruption of the pump function of myocardium.
Occasionally, at a previously existing nephropathy, albuminuria and hematuria may occur. Observed in some cases when the benzylpenicillin of Oliguria or Anururia is prescribed, usually pass 48 hours after the cessation of treatment. The diuresis can be restored with the appointment of a 10% solution of mannitol.
Carefully Appoint penicillin patients with allergies.
Banal infections do not require benzylpenicillin treatment.
Application with violations of liver function
In patients with a pronounced degree of liver failure, it is desirable to pick up one-time doses or intervals between doses individually (see "Dosing Mode").
Application with violations of the kidney function

From the CNS: With the use of benzylpenicillin in high doses, especially in the endolumbal administration, the development of neurotoxic reactions is possible: nausea, vomiting, increasing reflex excitability, symptoms of meningism, convulsions, coma.
Allergic reactions: Increase body temperature, urticaria, skin rash, rash on mucous membranes, joint pain, eosinophilia, angioedema edema. Cases of anaphylactic shock with fatal outcome are described.
Application during pregnancy is possible only when the intended benefit of therapy for the mother exceeds the potential risk to the fetus.
If you need to use during the lactation period, it is necessary to resolve the issue of cessation of breastfeeding.
The probilecid reduces the tubular secretion of benzylpenicillin, as a result, the concentration of the latter in the blood plasma increases, the half-life increases.
With simultaneous use with antibiotics that have a bacteriostatic effect (tetracycline), the bactericidal effect of benzylpenicillin decreases.
Caution is used in patients with impaired kidney function, with heart failure, predisposition to allergic reactions (especially during drug allergies), with increased sensitivity to cephalosporins (due to the possibility of developing cross-allergies).
If after 3-5 days after the start of the use of the effect, it is not noted, it is necessary to proceed to the use of other antibiotics or combined therapy.
In connection with the possibility of the development of fungal superinfection, it is advisable in the treatment of benzylpenicillin to prescribe antifungal drugs.
It is necessary to take into account that the use of benzylpenicillin in subterapeutic doses or early cessation of treatment often leads to the emergence of resistant strains of pathogens.
With violations of the kidney function
Caution is used in patients with impaired kidney function.
