Pharmacological action
An antibiotic of the carbapenemov group, represents the 1-methyl β-karbapenem, Beta-laktamnyj long-acting antibiotic for parenteral, with activity against a broad spectrum of Gram-positive and Gram-negative aerobic and anaerobic bacteria.
Bactericidal activity of jertapenema is due to inhibition of cell wall synthesis and mediated by its binding to penicillin-binding proteins (PSB). Escherichia coli have he has a strong affinity to the PSB 1a , 1b , 2, 3, 4 and 5, preferably – the PSB 2 and 3. Jertapenem has a considerable resistance to the action of β-lactamases most classes (including penicillinase, cefalosporinazy and β-lactamaza extended range, but not metal-β-lactamaza).
Invanz® effective against most strains of the following microorganisms in vitro and when called by infections.
It is active against aerobic and facultative anaerobic gram-positive microorganisms: Staphylococcus aureus(including strains, producyrute penitsillinazou/Methicillin-resistant staphylococci resistant/), Streptococcus agalactiae, Streptococcus pneumoniae, Streptococcus pyogenes.
Many strains of Enterococcus faecalis and Enterococcus faecium strains most resistant.
Active against aerobic and facultative anaerobic gram-negative microorganisms: Escherichia coli, Haemophilus influenzae (including strains, producing β-laktamazu), Klebsiella pneumoniae, Moraxella catarrhalis, Proteus is wonderful.
Active in regard to anaerobic Microorganisms: Bacteroides fragilis and other Bacteroides spp., microorganisms of the genus Clostridium (other than Clostridium difficile), microorganisms of the genus Eubacterium, microorganisms of the genus Peptostreptococcus, Porphyromonas asaccharolytica, microorganisms of the genus Prevotella.
Invanz® When the IPC ≤ 2 µg/ml is active against most (≥ 90%) strains of microorganisms of the genus Streptococcus, including Streptococcus pneumoniae, When the IPC ≤ 4 ug / ml – against the majority of (≥ 90%) strains of microorganisms of the genus Haemophilus, against the majority of (>90%) strains of aerobic and facultative anaerobic Gram-positive microorganisms (Staphylococcus spp., koagulazonegativnye Methicillin-sensitive/Methicillin-resistant staphylococci resistant/, Streptococcus pneumoniae, penicillin-resistant Streptococcus viridans). The clinical significance of these data on the values of the IPC, obtained in vitro, unknown.
Meticilin-resistant staphylococci, as well as many strains of Enterococcus faecium Enterococcus faecalisi most strains resistant to Invanzu®.
Active also in relation to aerobic and facultative anaerobic gram-negative microorganisms: Citrobacter freundii, Enterobacter aerogenes, Enterobacter cloacae, Escherichia coli (onwards, the β-lactamaza extended spectrum of activity), Haemophilus parainfluenzae, Klebsiella oxytoca, Klebsiella pneumoniae (producing β-lactamaza extended spectrum of activity), Morganella morgani, Proteus vulgaris, Serratia wilting.
Many strains of the microorganisms listed above, having multirezistentnostju to other antibiotics, eg, penicillins, cephalosporins (incl. Generation III) and aminoglycosides, sensitive to Invazu®.
Active against anaerobic microorganisms genus Fusobacterium.
Determined by the value of the IPC should be interpreted in accordance with the criteria, specified in tables.

Pharmacokinetics
Absorption
When the/m introduction solution, cooked with 1% or 2% lidocaine, jertapenem well absorbed from the introduction. Bioavailability is approximately 92%. After the / m dose 1 г Cmax is approximately 2 no.
Distribution
Jertapenem actively communicates with human plasma proteins. The degree of binding decreases with increasing concentrations of plasma jertapenema – approximately 95% When plasma concentration <100 ug/mL to about 85% When plasma concentration 300 ug / ml).
Mean concentrations (ug / ml) plasma jertapenema, achieved after a single 30-minute in/in infusion of the drug at a dose of 1 or g 2 , and after the/m introduction in one dose 1 g in healthy young adult volunteers, are presented in Table.

The AUC is increased almost directly proportional dose (in the range of doses from 0.5 g to 2 g).
Cumulation jertapenema after in/introductions (in the range of doses from 0.5 to 2 g / day) or/m introduction to 1 g/day is not observed.
Vd about jertapenema 8 l (0.11 l / kg).
Jertapenema concentration in the breast milk of lactating women (5 Pax.), defined daily at random time points during the 5 days after the last injection, in/in the dose of 1 g was: on the last day of treatment (through 5-14 days postpartum) <0.38 ug / ml; to 5 the day after the end of treatment concentrations at jertapenema 4 women was indefinable, and in 1 women – in trace quantities (<0.13 ug / ml).
Jertapenem does not inhibit the transport of Digoxin and vinblastine, mediated p-glycoproteins, and he himself is not a substrate.
Metabolism
After the on/in infusion jertapenema with isotope labeled dose 1 g source of radioactivity in the plasma is mainly (94%) jertapenem. The main metabolite is a jertapenema derivative with open ring, formed during the hydrolysis of β-laktamnogo rings.
Deduction
Jertapenem write mainly kidneys. The Mean T1/2 from the plasma of healthy young adult volunteers is approximately 4 no. After the on/in the jertapenema with isotope labeled dose 1 g healthy young volunteers around 80% the label appears in the urine, and 10% – with feces. From 80% jertapenema, determined in the urine, about 38% excreted unchanged, and about 37% – in the form of metabolita with β-lactam ring watch.
Healthy young adult volunteers, received jertapenem in/in the dose 1 g, the average concentration of jertapenema in the urine within 0-2 h after the introduction of this dose exceeds 984 ug / ml, and for 12-24 no – more than 52 ug / ml.
Pharmacokinetics in special clinical situations
Jertapenema concentration in plasma is comparable for men and women.
Jertapenema concentration in plasma after in/in the dose 1 and g 2 g in older adult patients (senior 65 years) slightly above (approximately 39% and 22% respectively), than in younger. Correction dose for elderly patients is not required.

Vd jertapenema in children aged 3 Months before 12 years – 0.2 l/kg and about 0.16 l/kg in children 13-17 years.
Pharmacokinetics of jertapenema in patients with hepatic insufficiency have not studied. Due to the low intensity of its metabolism in the liver can be expected, that violation of its functions should not affect the farmakokinetiku jertapenema and correction mode in patients with hepatic insufficiency do not require.
After a single on/in the introduction jertapenema in dose 1 g the AUC in patients with renal insufficiency light gravity (KK from 60 to 90 ml / min / 1.73 m2) is no different from that of healthy volunteers (aged 25 to 82 years).
In patients with renal insufficiency, moderate severity (CC 31-59 ml / min / 1.73 m2) AUC increased approximately 1.5 fold compared with healthy volunteers.
Patients with severe renal insufficiency (CC 5-30 ml / min / 1.73 m2) AUC increased approximately 2.6 fold compared with healthy volunteers.
In patients with end stage renal failure (CC<10 ml / min / 1.73 m2) AUC increased approximately 2.9 fold compared with healthy volunteers. After a single on/in the introduction jertapenema in dose 1 g just before hemodialysis session about 30% the administered dose is determined in dialysate.
Patients with severe renal impairment or end-stage correction is recommended dosage.
Testimony

- Intra-abdominal infections;
- Infections of the skin and subcutaneous tissue, including infection of lower limbs in diabetes (diabetic foot);
- Community-acquired pneumonia;
- Urinary tract infection (incl. pyelonephritis);
— acute pelvic infection (incl. Postpartum endomyometritis, Septic abortion and post-operative gynecological infections);
-bacterial septicaemia.
Dosage regimen
The average daily dose for Adult and adolescents aged 13 and older is 1 g, multiplicity of introduction – 1 time / day.
Children aged 3 Months before 12 years Invanz® administered at a dose of 15 mg / kg 2 once a day (but not more 1 g / day).
The drug is injected through the on/in infusion or/m injection. When in/with the introduction of infusion duration shall be 30 m.
In/m introduction can be an alternative to the on/in infusion.
The normal duration of therapy ranges from 3 to 14 days depending on the severity of the disease and the type of microorganisms. If there is clinical evidence is valid transition to subsequent adequate oral antibacterial therapy.
The drug can be used to treat infections in patients with renal insufficiency. Patients with CC>30 ml / min / 1.73 m2 correction dosing regime is not required. In patients with severe renal impairment (CC ≤ 30 mL/min/1.73 m2), including patients, hemodialysis, The recommended dose is 500 mg / day. No data on the use of drugs in children with renal failure.
Adult patients, hemodialysis and received the drug in a dose 500 mg/day in the coming 6 hours before dialysis session, should further introduce 150 mg of the drug after the session. If the drug is injected more than 6 hours before hemodialysis, introduction of an additional dose is not required. At the present time there is insufficient data on the recommendation of the sick, in peritoneal dialysis or Hemofiltration. No data on the use of drugs in children, hemodialysis.
If you know the concentration of creatinine in the serum, then to calculate creatinine clearance, you can apply the following formula:
For men:
QC = (weight in kg) x (140-age in years)/72 x serum creatinine (mg / dL)
For women:
QC = 0.85 x (value, designed for men)
In patients with impaired liver function dose adjustment is required. The recommended dose can be administered without regard to age and gender.

Most adverse events, reported during clinical trials, for severity described as mild or moderate. In connection with undesirable phenomena, that presumably could be associated with drug, jertapenem terminated at 1.3% patients.
The most frequent adverse events, associated with parenteral introduction preparation, included diarrhea (4.3%), local complications after in/introductions (3.9%), nausea (2.9%) and headache (2.1%).
In injecting a jertapenema reported adverse events listed below, associated with drug, and using the following criteria to assess the incidence of adverse events: often (<10%, but >1%); rarely (<1%, but >0.1%).
Local reactions: often – postinfuzionnye phlebitis/thrombophlebitis.
CNS: often – headache; rarely – dizziness, drowsiness, insomnia (0.2%), convulsions, confusion.
From the digestive system: often – diarrhea, nausea, vomiting; rarely – candidiasis of the oral mucosa, constipation, regurgitation content, psevdomembranoznыy colitis (often manifested by diarrhea), caused by uncontrolled reproduction Slostridium difficile, dry mouth, dyspepsia, anorexia.
Cardio-vascular system: rarely – decrease in blood pressure.
The respiratory system: rarely – dyspnoea.
Dermatological reactions: rarely – эritema, itch.
By genitalia: vaginal itching.
From the body as a whole: rarely – abdominal pain, dysgeusia, weakness / fatigue, candidiasis, puffiness, fever, chest pain.
From the laboratory parameters: often – ALT increase, ACT, Alkaline phosphatase, the increase in the number of platelets; rarely – improvement direct, indirect and total bilirubin, increase in the number of eosinophils and monocytes, improved partial thromboplastin time, creatinine and blood glucose, the decrease in the number of neutrophils and leukocytes segmentojadernyh, decrease in hematocrit, hemoglobin and platelet count; bacteriuria, increased levels of serum urea nitrogen, the number of epithelial cells in urine, the number of red blood cells in the urine.
In most clinical studies parenteral therapy preceded the transition to the corresponding oral antimicrobial medication. For the whole period of treatment and within 14 days of follow-up adverse events, associated with the use of Invanza®, included: often – rash, vaginitis (>1%); rarely – allergic reactions, general malaise, fungal infections (0.1% to 1.0%).
Children
The most frequent adverse events, associated with the use of jertapenema when it is injecting, included diarrhea (5.5%), pain at the injection site (5.5%), redness at the injection site (2.6 %).
When injecting treatment of children jertapenemom the following adverse events were reported, associated with drug:
From the digestive system: rarely – diarrhea, vomiting.

Local reactions: rarely – эritema, pain at the injection site, phlebitis, local postingyektinaya reaction.
From the laboratory parameters: often – neutropenia; rarely – ALT increase, ACT, leukopenia, eozinofilija.
Rarely reported on the serious and fatal anaphylactic reactions in patients, treated with beta-lactam antibiotics. These reactions are more likely to occur in individuals, with a history of allergy polyvalent (in particular, in patients with hypersensitivity to penicillin, often develop severe hypersensitivity reactions when treating other beta-lactam). Before starting treatment with Invanz® You should carefully question the patient about previous hypersensitivity reactions to other allergens, especially, of penitsillinы, cephalosporins other beta-lactams.
If you experience an allergic reaction to a drug Invanz® it should be lifted immediately. Serious anaphylactic reactions require emergency treatment.
Contraindications
— installed hypersensitivity to the drug or to other antibiotics in the same group;
- Hypersensitivity to other beta-lactam antibiotics.
When used as a solvent of lidocaine hydrochloride in the/m introduction the drug is contraindicated in patients with hypersensitivity to installed amide local anesthetic action, patients with severe arterial gipotenziei or intracardiac conduction.
Pregnancy and lactation
Adequate clinical experience of applying Invanza® during pregnancy is not. Use of the drug is possible only in cases, the projected benefits of therapy to the mother justifies the potential risk to the fetus.
Be wary appoint drug in lactation (breast-feeding), tk. jertapenem out of breast milk.
Cautions
Prolonged use of Invanza®, as well as other antibiotics, can lead to excessive growth of insensitive microorganisms. In developing superinfection should adopt appropriate measures.
When applied to nearly all antibacterial drugs, including jertapenem, may develop psevdomembranoznogo colitis (the main reason of which is Toxin, produced by Clostridium difficile ). The severity of colitis can vary from slight to endangering life. Should take into account the possibility of developing such complications when an expressed diarrhoea in patients, treated with antibacterial therapy.
When the/m introduction should proceed with caution, to avoid inadvertent injection into a blood vessel.
In clinical trials the efficacy and safety of medication in the elderly (senior 65 years) were comparable with those in younger patients.
Use in Pediatrics
Use of the drug to children aged 3 Months not recommended.
Overdose
No specific information about the drug overdose no. In clinical trials the drug in a dose of random to 3 g / day did not lead to clinically significant adverse events. In clinical studies in children single in/with the introduction of the drug in the dose of 40 mg/kg up to 2 g maximum did not cause toxic reactions.
Treatment: drug should be lifted and to conduct general supportive therapy (to complete removal of jertapenema from the body). The drug can be removed from the body by hemodialysis, but information about the application of hemodialysis for treatment of an overdose is not available.
