Firomu Pediatric Faropenem Sodium Granules

1. Indications and Usage
Pediatric Bacterial Infections: Treatment of infections caused by bacteria susceptible to Faropenem Sodium.
Common Infection Sites: Includes respiratory tract infections (e.g., tonsillitis, pneumonia, bronchitis), urinary tract infections, and skin infections.
2. Dosage and Administration
Route of Administration: Oral administration ONLY. The granules should be dissolved in an appropriate amount of water before administration.
Dosing Principle: The dosage must be determined by a physician based on the type of infection, severity, and the patient’s specific condition.
Critical Administration Instructions:
Preparation: The medication must be prepared immediately before use. It cannot be stored for a long time after being dissolved in water. If refrigeration is necessary, it must be used as soon as possible.
3. Mechanism of Action
Cell Wall Inhibition: Faropenem sodium is a penem antibiotic with a penem basic skeleton. It inhibits bacterial cell wall synthesis, exerting potent bactericidal effects.
Target Affinity: It exhibits high affinity for various penicillin-binding proteins (PBPs), particularly high-molecular-weight PBPs essential for bacterial proliferation.
Spectrum: In vitro studies demonstrate broad-spectrum activity against aerobic Gram-positive bacteria, aerobic Gram-negative bacteria, and anaerobic bacteria.
4. Safety and Warnings
Hypersensitivity: Contraindicated in patients with a history of anaphylactic shock or hypersensitivity to this drug. Caution is required for patients with a history of hypersensitivity to penicillins, cephalosporins, or carbapenems.
Pregnancy and Neonates: The safety of Faropenem Sodium for premature infants and newborns has not been established.
Vitamin K Deficiency: In patients with poor oral intake or those receiving non-oral nutritional therapy, vitamin K deficiency may occur.
5. Adverse Reactions and Clinical Research
Common Adverse Reactions: Diarrhea and loose stools are the most frequently reported adverse reactions. Other common symptoms include abdominal pain, rash, nausea, and increased liver enzymes (ALT, AST).
Severe Adverse Reactions:
Shock and Anaphylaxis: Monitor for symptoms such as dizziness, dyspnea, flushing, or hypotension.
Renal and Hepatic Dysfunction: May cause acute renal impairment, elevated liver enzymes, and jaundice.
Severe Colitis: Rarely may cause pseudomembranous colitis.
Severe Dermatologic Reactions: Rarely may cause Stevens-Johnson syndrome or toxic epidermal necrolysis.
6. Drug Interactions
Probenecid: Probenecid inhibits the renal tubular secretion of faropenem sodium, potentially increasing plasma concentrations.
Vitamin K Antagonists: May potentiate the effects of anticoagulants such as warfarin.
Aminoglycosides: Concomitant administration may reduce the efficacy of aminoglycosides due to drug incompatibility.
7. Pharmaceutical Information
Chemical Composition: Active Ingredient: Faropenem Sodium Hydrate.
Appearance: White to slightly yellow granules.
Packaging: Available in various strengths (e.g., 50 mg/granule).
