Ceftriaxone Sodium

Ceftriaxone sodium is a powerful medication used to combat severe bacterial infections in dogs. As a third-generation cephalosporin, it offers broad-spectrum coverage, targeting both Gram-positive and Gram-negative bacteria, which can complicate treatment plans. The bactericidal action is achieved through the inhibition of mucopeptide synthesis in the bacterial cell wall, leading to bacterial destruction.

Key Benefits of Ceftriaxone Sodium:

• Broad-spectrum antibiotic: Effective against a wide variety of bacteria
• Bactericidal action: Kills bacteria rather than just inhibiting their growth
• Targets Gram-positive and Gram-negative bacteria

Conditions Treated with Ceftriaxone Sodium:

• Respiratory tract infections
• Acute bacterial otitis media
• Skin infections
• Bone and joint infections
• Intra-abdominal infections
• Bacterial septicemia

Ceftriaxone sodium is especially useful for treating infections in difficult-to-reach areas due to its ability to cross the blood-brain barrier and blood-placenta barrier. It is widely distributed across various organ systems when administered, making it a highly effective treatment for severe systemic infections.
