    Product Introduction

    Item Cefdinir
    Cas No. 91832-40-5
    Purity >99

    1. Product Overview


    Cefdinir (CAS No.: 91832-40-5) is a third-generation oral cephalosporin antibiotic with broad-spectrum antibacterial activity. It appears as a white to pale yellow crystalline powder. As a synthetic β-lactam antibiotic, it has high stability against most β-lactamases, with definite antibacterial efficacy and good clinical tolerability. Its molecular formula is C₁₄H₁₃N₅O₅S₂ and molecular weight is 395.41.

    2. Mechanism of Action


    Cefdinir exerts antibacterial effects by inhibiting bacterial cell wall synthesis. It binds to penicillin-binding proteins (PBPs) on the bacterial cell membrane, interfering with the cross-linking of peptidoglycan—a key component of bacterial cell walls. This leads to defective cell wall formation, making bacteria unable to maintain their morphology and ultimately causing bacterial lysis and death. It has strong inhibitory effects on both gram-positive and gram-negative bacteria.

    3. Core Functions & Antibacterial Spectrum


    1. Broad-spectrum antibacterial activity: Effective against common pathogenic bacteria including Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes, Haemophilus influenzae, Moraxella catarrhalis, Escherichia coli, Klebsiella pneumoniae and Proteus mirabilis.
    2. β-lactamase resistance: Not easily hydrolyzed by most β-lactamases produced by drug-resistant bacteria, thus showing good therapeutic effects on infections caused by β-lactamase-producing strains.
    3. Low toxicity & good tolerability: Has minimal impact on the normal flora of the human body, with mild and reversible adverse reactions mainly including gastrointestinal discomfort and skin rashes.

    4. Application Scope


    Clinically, it is mainly used to treat infections caused by susceptible bacteria, covering multiple systems:

    1. Respiratory tract infections: Acute bronchitis, pneumonia, acute exacerbation of chronic bronchitis, pharyngitis, tonsillitis, sinusitis, otitis media;
    2. Urinary system infections: Cystitis, pyelonephritis, urethritis;
    3. Skin and soft tissue infections: Folliculitis, furuncle, carbuncle, cellulitis, wound infection;
    4. Other infections: Acute gonorrhea, pelvic inflammatory disease, dental infections, biliary tract infections.

    5. Usage Precautions & Adverse Reactions


    1. Adverse reactions: The most common reactions are gastrointestinal symptoms such as diarrhea, nausea, vomiting and abdominal pain; occasional skin reactions including rash and pruritus; rare cases involve headache, dizziness, elevated liver enzymes and thrombocytopenia.
    2. Contraindications: It is contraindicated for patients with a history of allergy to cefdinir, other cephalosporins or penicillins.
    3. Special populations: Pregnant women should use it with caution only when the benefits outweigh the risks; the drug can be secreted into breast milk, so lactating women should suspend breastfeeding during medication; dosage adjustment is required for patients with renal insufficiency.
    4. Drug interactions: Concurrent use with probiotics may reduce the efficacy of probiotics; combined use with diuretics may increase the risk of renal damage.

    6. Storage Conditions


    1. Store in a cool, dry and well-ventilated place, away from direct sunlight and heat sources;
    2. Control the storage temperature between 2℃ and 8℃, strictly prohibit freezing;
    3. Keep the package tightly sealed to prevent moisture absorption, oxidation and contamination;
    4. Store separately from toxic, harmful and incompatible substances;
    5. The shelf life is 24 months under specified storage conditions; do not use the product beyond the expiration date.
