Uses
Longicef Monohydrate (Longicef Monohydrate) is used for the treatment of patients with infection caused by susceptible strains of the designated organisms in the following diseases:
*Upper respiratory tract infections caused by Streptococcus pyogenes (Group A beta-hemolytic Streptococci) and Streptococcus pneumoniae.
* Urinary tract infections caused by E. coli, Proteus mirabilis, and Klebsiella species.
* Skin and soft tissue infections caused by Staphylococci (including penicillinase producing strains) and Streptococci.
Longicef is also used to associated treatment for these conditions: Bacterial Infections, Infection and inflammatory reaction due to internal prosthetic device, implant, and graft, Skin and Subcutaneous Tissue Bacterial Infections, Streptococcal Pharyngitis, Streptococcal tonsillitis, Urinary Tract Infection
How Longicef works
Like all beta-lactam antibiotics, cefadroxil binds to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, causing the inhibition of the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins; it is possible that cefadroxil interferes with an autolysin inhibitor.
