Slightly undergoes biotransformation.

Binding to blood plasma proteins is 40-60%. Passes through the placental barrier and enters breast milk.

It is well distributed in liquids, while the distribution in tissues is low.

Removal

It is excreted primarily by the kidneys.

Bicillin-5 1,500,000 units powder for the preparation of a suspension for intramuscular administration

Bicillin-5 1500000 units for injection

Bicillin-5 is an antibiotic (biosynthetic penicillin).

Release form and composition

The drug is produced in the form of a powder for the preparation of a suspension for intramuscular administration: a white or white with a yellowish tint, a powdery mass prone to clumping, with the addition of water it forms a stable suspension (10 ml in bottles; in a cardboard pack 1, 5, 10 or 50 bottles) .

Powder composition (per 1 bottle):

benzylpenicillin procaine (benzylpenicillin novocaine salt) – 300,000 units; benzathine benzylpenicillin – 1,200,000 units. Pharmacological properties Pharmacodynamics Bicillin-5 is a bactericidal combination antibiotic containing two long-acting benzylpenicillin salts. Inhibits the synthesis of the cell wall of pathogenic microorganisms. Active against the following microbes: gram-positive: Streptococcus spp. (including Streptococcus pneumoniae), Staphylococcus spp. (non-penicillinase-forming), Bacillus anthracis, Clostridium spp., Corynebacterium diphtheriae, anaerobic spore-forming rods, Actinomyces israelii; gram-negative: Treponema spp., Neisseria gonorrhoeae, Neisseria meningitidis. Penicillinase-producing strains of Staphylococcus spp. are resistant to the drug. Pharmacokinetics Bicillin-5 is a long-acting antibiotic; its high concentration in the blood persists for 4 weeks. Benzathine benzylpenicillin hydrolyzes very slowly after intramuscular injection, releasing benzylpenicillin. The maximum concentration (Cmax) in the blood serum is achieved 12–24 hours after administration. The long half-life ensures a long and stable concentration of the drug in the blood: on the 14th day after injection of 2,400,000 IU, the drug concentration in serum is 0.12 μg/ml; on the 21st day after administration - 1,200,000 IU, the concentration is 0.06 μg/ml (1 IU = 0.6 μg). Diffusion of the substance in tissue is very weak, in liquid it is complete. Plasma protein binding is 40–60%. Benzathine benzylpenicillin passes in small volumes through the placental barrier and also passes into breast milk. Biotransformation is insignificant, mainly excreted unchanged by the kidneys, up to 33% of the administered dose is excreted in 8 days. Benzylpenicillin reaches its maximum concentration in blood plasma when administered intramuscularly after 20–30 minutes. The half-life is 0.5–1 hour; in the presence of renal failure, this figure increases to 4–10 hours or more. Plasma protein binding ~ 60%. The substance penetrates into tissues, organs and biological fluids, except for eye tissue, cerebrospinal fluid and prostate gland. Passes through the blood-brain barrier during inflammation of the meningeal membranes. Penetrates the placenta and enters breast milk. It is excreted unchanged by the kidneys.

Indications for use Bicillin-5

used for the treatment of the following infectious and inflammatory diseases/conditions provoked by pathogens sensitive to the drug: rheumatism - for year-round long-term prevention of relapses; syphilis; yaws; streptococcal infections (except for infections caused by group B streptococci) - scarlet fever, acute tonsillitis, erysipelas, wound infections.

Absolute contraindications:

breastfeeding period; hypersensitivity to any components of the drug and other beta-lactam antibiotics. Relative: bronchial asthma; burdened allergy history; pregnancy; renal failure; pseudomembranous colitis. Instructions for use of Bicillin-5: method and dosage A suspension prepared from powder is administered intramuscularly (i.m.). Recommended dosages of Bicillin-5: children under 8 years of age: 480,000 units + 120,000 units once every 3 weeks; children over 8 years old: 960,000 units + 240,000 units once every 4 weeks; adults: 1,200,000 units + 300,000 units once every 4 weeks. When preparing the suspension, it is recommended to use a 0.25–0.5% solution of novocaine (procaine), isotonic sodium chloride solution or sterile water for injection. The suspension is prepared under aseptic conditions, immediately before use (ex tempore): 5-6 ml of solvent is slowly introduced into a bottle with Bicillin-5 under pressure (at a rate of 5 ml in 20-25 seconds). The contents are mixed and shaken along the longitudinal axis of the bottle until a homogeneous suspension is formed. There may be bubbles near the walls of the bottle on the surface of the suspension. The finished drug must be injected deep intramuscularly into the upper outer quadrant of the gluteal muscle immediately after preparation. It is not recommended to rub the gluteal muscle after the injection. If administration is delayed after preparation, the colloidal and physical properties of the suspension change, as a result of which its movement through the syringe needle may be difficult. Side effects: allergic reactions: anaphylactoid reactions, fever, urticaria, angioedema, arthralgia, exfoliative dermatitis, exudative erythema multiforme, anaphylactic shock; laboratory parameters: leukopenia, thrombocytopenia, anemia, hypocoagulation; others: glossitis, stomatitis. Overdose There is no information about overdose. Special instructions Intravenous, endolumbar and subcutaneous administration of the suspension, as well as injections into body cavities, are not allowed. With unintentional intravascular administration, a transient feeling of anxiety, depression and visual disturbances (Wanier syndrome) may occur. To avoid inadvertent intravascular injection of the drug, aspiration should be performed before intramuscular injection in order to identify possible needle entry into the vessel. When treating syphilis, serological and microscopic studies should be carried out before starting treatment and for 4 months. Due to the development of fungal infections, it is advisable to prescribe vitamin C and B vitamins at a time, and if necessary, prescribe antifungal agents for systemic use. It is important to consider that stopping therapy too early or using an insufficient dosage of Bicillin-5 can lead to the emergence of resistant strains of pathogens.

Use during pregnancy and lactation

According to the instructions, Bicillin-5 penetrates into mother's milk and through the placental barrier in small quantities. Its use during pregnancy is allowed only when the expected benefit to the mother outweighs the potential risk to the fetus. If it is necessary to prescribe the drug during lactation, breastfeeding should be discontinued.

Drug interactions: bactericidal antimicrobial drugs, including vancomycin, cephalosporins, aminoglycosides, rifampicin: have a synergistic effect; bacteriostatic antimicrobial drugs, including chloramphenicol, macrolides, tetracyclines, lincosamides: have an antagonistic effect; indirect anticoagulants: their effectiveness increases due to the inhibition of intestinal microflora and a decrease in the prothrombin index; oral contraceptives, drugs whose metabolism occurs with the formation of para-aminobenzoic acid, ethinyl estradiol: the antibiotic reduces their effectiveness, increasing the risk of breakthrough bleeding; blockers of tubular secretion, diuretics, allopurinol, non-steroidal anti-inflammatory drugs, phenylbutazone: reduce tubular secretion, increase the concentration of benzylpenicillin in tissues and blood; allopurinol: increases the risk of allergic reactions such as skin rash. Analogues Analogues of Bicillin-5 are: Benzylpenicillin, Benzylpenicillin sodium salt, Benzylpenicillin sodium salt-Vial, Benzylpenicillin novocaine salt.

Terms and conditions of storage

Dosage

Bicillin-3 is injected deep into the upper outer quadrant of the buttock in a dose of no more than 1.2 million units. If 2 injections are necessary, they are given in different buttocks. Repeated injections are carried out 4 days after the previous injection. The drug in a dose of 600,000 units is administered once every 6 days. In the treatment of primary and secondary syphilis, a single dose of the drug is 1.8 million units. The course of treatment is 7 injections. The first injection is carried out at a dose of 300,000 units, the second injection - after 1 day at the full dose (1.8 million units). Subsequent injections are carried out 2 times a week. In the treatment of secondary recurrent and latent early syphilis, a dose of 300,000 units is used for the first injection, and 1.8 million units for subsequent injections. Injections are carried out 2 times a week. The course of treatment is 14 injections. Intravenous administration of the drug is prohibited. Rules for preparing and administering the solution Bicillin-3 suspension is prepared immediately before use. 2-3 ml of sterile water for injection or isotonic sodium chloride solution is injected into the bottle with the drug. The mixture in the bottle is shaken for 30 seconds (in the direction of the longitudinal axis) until a homogeneous suspension (or suspension) is formed, which is injected deep intramuscularly into the upper outer quadrant of the buttock. Rubbing the buttock after the injection is not recommended.

Side effects of the drug Bicillin-5

Some patients, especially those with hypersensitivity to penicillins and procaine, experience headache, fever, urticaria, rash on the skin and mucous membranes, joint pain, eosinophilia, angioedema, anaphylactic shock and other allergic reactions. After injection of the drug (like other long-acting penicillin preparations), pain at the injection site is possible. Patients who have experienced unusual reactions to the drug should be under constant and direct medical supervision until the reactive phenomena completely disappear. In severe cases, 0.5–0.6 ml of 0.1% atropine solution is administered, injections of 1 ml of 0.1% epinephrine solution or 1 ml of 5% ephedrine solution, injection of 1–2 ml of 2% solution -ra chloropyramine.

Drug interactions

When used simultaneously with bactericidal antibiotics (including cephalosporins, cycloserine, vancomycin, rifampicin, aminoglycosides), a synergistic effect is observed; with bacteriostatic antibiotics (including macrolides, chloramphenicol, lincosamides, tetracyclines) - antagonism.

Bicillin-3 reduces the effectiveness of oral contraceptives and ethinyl estradiol (risk of breakthrough bleeding).

With the simultaneous use of Bicillin-3 with allopurinol, the risk of developing allergic reactions increases.

Pharmacokinetic interaction

With simultaneous use of diuretics, allopurinol, phenylbutazone, NSAIDs, they reduce tubular secretion and increase the concentration of penicillin.

special instructions

If allergic reactions develop, treatment should be stopped immediately.

With the development of anaphylactic shock, anti-shock therapy is indicated (administration of norepinephrine, corticosteroids, mechanical ventilation).

Intravenous and endolumbar administration is not allowed, because possible development of Wannier syndrome (depression, anxiety, paresthesia, visual impairment).

When treating sexually transmitted diseases, if syphilis is suspected, before starting therapy and then for 4 months, microscopic and serological studies are necessary.

In connection with the possible development of fungal infections, it is advisable to prescribe antifungal drugs (nystatin, levorin), as well as ascorbic acid and B vitamins.

It must be taken into account that the use of the drug in insufficient doses or early cessation of treatment leads to the emergence of resistant strains of pathogens.
