Vancomycin Hydrochloride Injection Pharmacy Bulk Glass Vial 5 Gram by Pfizer (RX)

Vancomycin Hydrochloride Injection is an antibiotic used to treat severe bacterial infections, especially those caused by methicillin-resistant Staphylococcus aureus (MRSA) and other Gram-positive bacteria. It is commonly administered to manage serious infections such as sepsis, endocarditis, and skin infections when other antibiotics are ineffective. The injection helps inhibit bacterial cell wall synthesis, ultimately killing the bacteria. Vancomycin is critical in hospital settings for treating life-threatening infections resistant to standard treatments.

Details and Features:

Concentration and Formulation: Each vial contains 5 grams of Vancomycin Hydrochloride, providing a robust amount suitable for multiple dosing regimens in critical care.
Packaging: Supplied in glass fliptop vials for ease of use and safety, enhancing stability and sterility upon multiple entries until preparation is complete.
Indications: Indicated for serious or severe infections caused by susceptible strains of methicillin-resistant staphylococci. Additional uses include treatment for C. difficile-associated diarrhea in adults.
Administration: Intravenous administration allows for immediate treatment against systemic infections, ensuring rapid attainment of therapeutic levels in the bloodstream.

Mechanism of Action:

Vancomycin is a glycopeptide antibiotic that exerts its bactericidal effect by inhibiting bacterial cell wall synthesis. It binds to the D-alanyl-D-alanine terminal of cell wall precursor units, obstructing peptidoglycan polymerization, critical for cell wall integrity. This action results in cell lysis and death, providing effective clearance of Gram-positive pathogens, particularly where beta-lactam antibiotics are ineffective due to resistance.

Warnings:

• Nephrotoxicity: Monitor renal function regularly; increased risk in patients with pre-existing renal impairment or those receiving concurrent nephrotoxic agents.
  
• Ototoxicity: Risk of auditory toxicity is heightened, especially with high serum concentrations or rapid infusion.
   Infusion Reactions: Infusion-related reactions like "red man syndrome," characterized by flushing and/or an erythematous rash affecting the face, neck, and upper torso, can occur. It's often linked to rapid infusion rates.
  
• Specific Considerations: Use cautiously in patients with a history of hearing loss. Serum vancomycin concentrations are recommended in these patients and, generally, in those receiving the medication for more than 3 days.

Side Effects:

• Hematologic Effects: Neutropenia, thrombocytopenia, and eosinophilia may occur with prolonged therapy.
  
• Renal Effects: Increased serum creatinine and decreased renal clearance leading to potential renal failure.
  
• Vein Irritation: Phlebitis and injection site pain/swelling.
  
• Hypersensitivity Reactions: Rash, fever, and, rarely, anaphylaxis.

Clinical Considerations:

• Dosage Adjustments: Dosage adjustments are necessary in cases of renal impairment to avoid accumulation and toxicity.
  
• Therapeutic Monitoring: Regular monitoring of serum trough concentrations, renal function, and hearing tests are advised, especially for those on prolonged therapies or high doses.
  
• Administration Rate: Infusions should be administered over at least 60 minutes to minimize rapid infusion reactions.

This advanced vancomycin formulation is designed for healthcare providers in acute care settings, offering reliable efficacy in combating severe bacterial infections. Healthcare professionals must consult the complete prescribing information and consider patient-specific factors when determining the optimal therapeutic approach.
