 Contraindications] Contraindicated in patients with a history of shock to the ingredients of this product.
In principle, it is contraindicated in patients with a history of hypersensitivity to the ingredients of this product.
Precautions]
1, the following patients should be used with caution
(1) Patients with a history of hypersensitivity to penicillins, cephalosporins or carbapenems.
(2) Patients who are prone to bronchial asthma, rash, urticaria and other allergic symptoms, such as parents or siblings.
(3) Patients who have poor oral intake or are receiving non-oral nutritional therapy, or patients with poor systemic status (sometimes vitamin K deficiency may occur and should be closely monitored).
(4) Patients with diarrhea (may lead to worsening of diarrheal symptoms and require close observation)
(5) Patients with severe renal dysfunction (the product is mainly excreted through the kidneys, and renal impairment may lead to prolonged drug half-life and prolonged sustained high blood concentration, so the dose should be reduced or the interval should be extended appropriately).
2. Attention when using
(1) Shock may occur when taking this product, so it should be fully investigated.
(2) The most common adverse effects of this product are diarrhea and loose stools, so when the following symptoms occur, control the dose and observe the condition of the stools. If symptoms such as diarrhea or loose stools occur, take appropriate measures (including discontinuation of the drug) according to the symptoms, extent and history.
In addition, when diarrhea or loose stools are observed, the patient or guardian should be instructed by the physician (see [Adverse Reactions] for details).
The incidence of side effects such as diarrhea and loose stools: children under 3 years of age (13.5%) is higher than children over 3 years of age (4.0%)
The incidence of side effects such as diarrhea and loose stools is higher in children under 3 years of age (13.5%) than in children over 3 years of age (4.0%).
(2) Symptoms such as diarrhea and loose stools are most likely to occur within 3 days after administration, so careful observation is particularly important during the initial period of administration.
(3) The incidence of diarrhea and loose stools tends to increase with increasing single dose (5.4% for 5mg/kg, 9.2% for 7.5mg/kg, 10.9% for 10mg/kg), so the dose should be observed.
(3) This product may cause superficial cutaneous Candida infection on the buttocks in children, which should be adequately observed and discontinued and appropriate measures taken when the above symptoms appear.
(4) Effects on clinical examination
(1) In addition to urine sugar test tape (Tes tape) reaction, Benedict’s reagent (Benedict’s reagent), Fehling’s reagent (Fehling’s reagent), copper sulfate containing tablet reagent (Clinitest) urine sugar test shows false positive reaction.
2) May lead to a positive result in the direct Coombs test.
[Pregnant and lactating women use].
For pregnant women or women who may become pregnant, do not take this product unless you can determine that the benefits of treatment outweigh the potential risks (the safety of use in pregnant women has not been established).
Since this product can be distributed into breast milk, avoid breast-feeding when using this product.
For Children]
The safety of this product has not been established for low birth weight infants and neonates (no experience with this product).
For Elderly]
This product is a granule, mainly used for the treatment of infectious diseases in children caused by bacteria sensitive to Faropenem. This product can also be used for the treatment of infectious diseases in adults caused by bacteria sensitive to faropenem.
Elderly patients need to be used with caution and special attention should be paid to the following matters, starting from 150mg per dose, paying attention to the patient’s status and careful administration (because the elderly generally have lower physiological functions and are prone to adverse reactions).
1, human pharmacokinetic tests on elderly patients show that compared with healthy adults, the blood half-life of elderly patients is prolonged and the blood concentration remains high for a long time, which may be related to increased age and low renal function.
2.Symptoms such as diarrhea and soft stools in elderly patients are likely to lead to worsening of systemic symptoms; therefore, adequate observation is required, and the drug should be discontinued and appropriate measures taken when these symptoms occur.
3. Bleeding tendency due to vitamin K deficiency may occur in elderly patients.

Pharmacology and Toxicology
Pharmacological effects
Faropenem sodium is a penicillin-based oral antibiotic with a basic penicillin backbone. It exerts antibacterial and bactericidal effects by preventing bacterial cell wall synthesis. It has high affinity for various penicillin binding proteins (PBPs), especially for PBPs, which are essential for bacterial proliferation.
In vitro test shows that faropenem sodium has a wide antibacterial spectrum against aerobic Gram-positive bacteria, aerobic Gram-negative bacteria and anaerobic bacteria; especially it shows strong bactericidal effect on Staphylococcus, Streptococcus, Pneumococcus and Enterococcus among aerobic Gram-positive bacteria, Citrobacter, Enterobacter and Pertussis among aerobic Gram-negative bacteria and Streptococcus digestiveis, Bacillus and Prevotella among anaerobic bacteria. It is also stable to various bacteria producing β-lactamase, and has strong antibacterial activity against bacteria producing β-lactamase.
Toxicological studies
Genotoxicity Ames test, cultured cell mutation test and chromosome abnormality test, and mouse micronucleus test did not find that faropenem sodium is mutagenic.
Reproductive toxicity
Oral administration of 320, 800 and 2000 mg/kg during organogenesis, 80, 360 and 1620 mg/kg during pre-pregnancy and early gestation, perinatal and lactation periods in rats showed no change in overall status and body weight, except for a slight change in food intake. The results showed that faropenem sodium had no effect on the reproductive function of mothers, fetuses and newborn rats, and no teratogenicity was observed.
In rabbits, intravenous administration of 50, 100 and 200 mg/kg during the organogenesis phase resulted in soft stools, diarrhea and abortion in the group administered above 100 mg/kg, and maternal mortality, increased fetal mortality and mild growth retardation in the group administered at 200 mg/kg, but no teratogenicity of faropenem sodium was observed.
Toxicity of repeated dosing
In rats and dogs given 100, 450 and 2000 mg/kg orally for 26 weeks, the rats showed decreased β-globin levels in the 450 mg/kg and above group, and the 2000 mg/kg group showed a transient decrease in food intake and decreased γ-GTP values. However, no mortality was observed in the 2000 mg/kg group. A decrease in erythrocyte levels occurred in the group administered above 450 mg/kg in dogs. The non-toxic dose of faropenem sodium for both rats and dogs was 100mg/kg.
Pharmacokinetics]
The pharmacokinetic studies in children presented in the literature are as follows.
Pharmacokinetics in children
(1) Blood concentration
In pediatric patients, 5 and 10 mg/kg were administered orally after meals, and the blood concentration peaked after about 1 hour, at 1.3 and 2.1 μg/ml, respectively, with a half-life of about 1 hour.

 (2) Tissue distribution (Faropenem sodium tablets, for adults)
It was distributed in patients’ sputum, wound exudate after tooth extraction, skin tissue, tonsils, mucosal tissue of maxillary sinus and prostate tissue.
(3) Metabolism (Faropenem Sodium Tablets, for adults)
The product is absorbed in its original form, partially excreted in urine as a prototype drug, and the rest is eliminated from urine after metabolism by dehydrogenase-1 (DHP-1) in the kidney. No metabolites of faropenem sodium with antibacterial activity have been found in human plasma and urine.
(4) Excretion
Mainly excreted by the kidneys. In children (after meal), urinary excretion rate (0~6 hours) is 3.7% and 3.1% for 5 and 10 mg/kg orally, respectively. Urinary drug peak (27μg/ml) is reached 2~4 hours after administration in 5mg/kg group, and urinary drug peak (41μg/ml) is reached 0~2 hours after administration in 10mg/kg group.
