Cefalexin + Probenecid treats bacterial infections by combining a cephalosporin antibiotic with an agent that prolongs its effect in the body.
This combination is commonly used for:
• Respiratory tract infections: Treats bacterial infections such as bronchitis, pneumonia, tonsillitis, and pharyngitis.
• Skin and soft tissue infections: Clears bacterial infections affecting the skin and underlying tissue.
• Bone and joint infections: Treats bacterial infections affecting the bones and joints.
• Urinary tract infections: Manages infections such as cystitis and prostatitis caused by susceptible bacteria.
• Dental infections: Treats bacterial infections of the gums and surrounding oral tissue.
Cefalexin + Probenecid works through two separate mechanisms to treat bacterial infections effectively.
Cefalexin is a first-generation cephalosporin antibiotic. It inhibits the synthesis of the bacterial cell wall by binding to and inactivating proteins essential for building the cell wall. This disrupts cell wall formation and leads to bacterial death.
Probenecid is a uricosuric agent that supports Cefalexin's action. It blocks certain channels in the kidneys that would normally remove Cefalexin from the body, allowing more of the antibiotic to remain in the bloodstream for longer without increasing the dose.
Together, both medicines provide a more sustained and effective defence against susceptible bacterial infections.
