Mechanism of action of Keflex
Keflex, also known by its generic name cephalexin, is an antibiotic medication that belongs to the class of drugs called cephalosporins. It is widely used to treat various bacterial infections, including urinary tract infections, respiratory tract infections, skin and soft tissue infections, and more. Understanding the mechanism of action of Keflex can help in comprehending how it effectively fights against these infections.
Interference with bacterial cell wall synthesis
Keflex works by interfering with the synthesis of bacterial cell walls, which are essential for their structural integrity and survival. The active ingredient, cephalexin, binds to specific proteins called penicillin-binding proteins (PBPs) in the bacterial cell wall.
This process inhibits the cross-linking of the peptidoglycan matrix, a key component of the bacterial cell wall. Cross-linking is responsible for maintaining the strength and rigidity of the cell wall. By disrupting this process, Keflex weakens the cell wall, making it more susceptible to osmotic pressure.
This increased vulnerability to osmotic pressure leads to the lysis or destruction of bacteria. As a result, Keflex effectively stops the growth and multiplication of bacteria, allowing the body’s immune system to clear the infection more effectively.
Targeting bacterial growth and reproduction
The inhibition of bacterial cell wall synthesis by Keflex is a bactericidal effect, meaning it kills the bacteria. By preventing the formation of new cell walls, Keflex hinders bacterial growth and reproduction.
It is worth noting that this mechanism of action is specifically targeted towards bacteria and not viruses or other microorganisms. Keflex, like other antibiotics, is ineffective against viral infections such as the common cold or the flu.
To ensure the optimal effectiveness of Keflex, it is important to take the prescribed dosage and complete the full course of treatment. This is crucial to fully eradicate the bacterial infection and prevent the development of antibiotic resistance.
