AVIZONE 1GM

Introduction:

AVIZONE 1GM Injection contains Cefoperazone 1000mg, a broad-spectrum third-generation cephalosporin antibiotic. It is designed for parenteral administration (intravenous or intramuscular) and is used to treat a wide range of bacterial infections. Cefoperazone works by inhibiting bacterial cell wall synthesis, resulting in bacterial cell lysis and death.

This formulation is highly effective against both Gram-positive and Gram-negative bacteria, including resistant strains that are not easily treated with first- or second-generation antibiotics. AVIZONE 1GM is a trusted choice in hospitals and clinics for managing severe infections such as respiratory tract infections, urinary tract infections, intra-abdominal infections, septicemia, skin and soft tissue infections, gynecological infections, and more.

Pharmacology & Mechanism of Action:

Cefoperazone is a β-lactam antibiotic that belongs to the cephalosporin family. It acts by binding to specific penicillin-binding proteins (PBPs) within bacterial cell walls, thereby blocking the transpeptidation step of peptidoglycan synthesis. This results in a weakened bacterial cell wall and ultimately bacterial cell death.

Cefoperazone exhibits strong stability against many β-lactamases (enzymes produced by bacteria to resist antibiotics), making it a potent option for difficult-to-treat infections.

Spectrum of Activity:

AVIZONE 1GM (Cefoperazone) is active against:

• Gram-positive bacteria:

  • Staphylococcus aureus (methicillin-sensitive strains)

  • Streptococcus pneumoniae

  • Streptococcus pyogenes

  • Streptococcus agalactiae

• Gram-negative bacteria:

  • Escherichia coli

  • Klebsiella species

  • Proteus mirabilis

  • Enterobacter species

  • Serratia marcescens

  • Haemophilus influenzae

  • Neisseria gonorrhoeae

  • Neisseria meningitidis

  • Pseudomonas aeruginosa (notable activity)

Therapeutic Indications:

AVIZONE 1GM is indicated for the treatment of moderate to severe infections caused by susceptible bacteria, including:

1. Respiratory Tract Infections:

   • Pneumonia (community-acquired or hospital-acquired)

   • Bronchitis

   • Lung abscesses

   • Empyema

2. Urinary Tract Infections (UTIs):

   • Pyelonephritis

   • Complicated and uncomplicated UTIs

   • Cystitis

3. Intra-Abdominal Infections:

   • Peritonitis

   • Cholecystitis

   • Cholangitis

   • Infected bile ducts

4. Septicemia and Bacteremia:

   • Life-threatening bloodstream infections caused by Gram-negative or Gram-positive bacteria

5. Skin and Soft Tissue Infections:

   • Cellulitis

   • Infected wounds

   • Post-operative infections

6. Gynecological Infections:

   • Endometritis

   • Pelvic inflammatory disease (PID)

   • Post-partum infections

7. Bone and Joint Infections:

   • Septic arthritis

   • Osteomyelitis

8. Gastrointestinal Infections:

   • Typhoid fever

   • Bacterial gastroenteritis

9. Other Severe Infections:

   • Meningitis

   • Ear, nose, and throat infections

   • Prophylaxis in surgical procedures (especially abdominal and biliary surgeries)

Dosage and Administration:

• Route: Intravenous (IV) or Intramuscular (IM) injection

• Usual Adult Dose:

  • 1–2 g every 12 hours, adjusted based on infection severity

  • In life-threatening infections, dosage can be increased (up to 12 g/day in divided doses)

• Pediatric Dose:

  • 50–200 mg/kg/day divided every 8–12 hours (adjust according to infection type and severity)

• Renal or Hepatic Impairment: Dose adjustment required

Reconstitution:

• For IM use, dissolve Cefoperazone 1g in sterile water or normal saline.

• For IV infusion, dilute further in compatible IV fluids.

Mechanistic Advantages:

• Broad Spectrum: Effective against both aerobic and anaerobic pathogens.

• Strong Anti-Pseudomonal Activity: Superior against Pseudomonas aeruginosa compared to many cephalosporins.

• β-lactamase Stability: Resistant to many β-lactamases, reducing antibiotic resistance risk.

• Dual Elimination: Excreted through both bile and urine, making it safer for renal-compromised patients.

Clinical Benefits:

1. Fast-Acting: Rapid onset of action with potent bactericidal activity.

2. Hospital-Grade Antibiotic: Preferred in severe infections requiring parenteral therapy.

3. Effective in Mixed Infections: Covers both Gram-positive and Gram-negative bacteria.

4. Reliable in Biliary Infections: High concentration in bile, ideal for gallbladder and biliary tract infections.

5. Safety in Renal Dysfunction: Since Cefoperazone is primarily excreted via bile, dose adjustments are minimal in renal impairment.

Pharmacokinetics:

• Absorption: Given parenterally (IV/IM), ensuring 100% bioavailability

• Distribution: Widely distributed in body fluids and tissues including bile, lungs, peritoneal fluid, and bone

• Protein Binding: 90–93%

• Metabolism: Minimal hepatic metabolism

• Excretion: Primarily via bile, some urinary excretion

• Half-life: 2 hours (may be prolonged in hepatic dysfunction)

Side Effects:

Like all antibiotics, AVIZONE 1GM may have mild to moderate side effects:

• Gastrointestinal: Diarrhea, nausea, vomiting

• Allergic: Rash, itching, urticaria

• Injection Site: Pain or swelling

• Hematologic: Transient leukopenia, eosinophilia

• Liver: Temporary liver enzyme elevation

• Superinfections: Possible fungal or resistant bacterial growth with prolonged use

Precautions:

• Perform allergy testing before use in patients with penicillin or cephalosporin hypersensitivity.

• Caution in patients with hepatic dysfunction.

• Monitor prothrombin time in patients on anticoagulants or vitamin K deficiency.

• Avoid alcohol consumption (Cefoperazone may cause disulfiram-like reaction).

• Prolonged use may lead to superinfection or antibiotic resistance.

Drug Interactions:

• Aminoglycosides: Synergistic effect, but use cautiously due to nephrotoxicity.

• Anticoagulants: Increased bleeding risk; monitor coagulation profile.

• Alcohol: Avoid due to disulfiram-like reaction (flushing, nausea, vomiting).

Storage:

• Store below 25°C in a cool, dry place, away from light.

• Reconstituted solution should be used immediately or as per manufacturer’s instructions.
