DescriptionECHEMI Editorial ReferenceCefalexin is a cephalosporin antibiotic.Target: AntibacterialCefalexin (INN, BAN) or cephalexin (USAN, AAN) is a first-generation cephalosporin antibiotic introduced in 1967 by Eli Lilly and Company. It is an orally administered agent with a similar antimicrobial spectrum to the intravenous agents cefalotin and cefazolin. It was first marketed as Keflex (Lilly), and is marketed under several other trade names. As of 2008, cefalexin was the most popular cephalosporin antibiotic in the Uni
Cephalexin is a cephalosporin antibiotic that is used to examine the impact of binding, expression, and inhibition of PBP3 as well as additional penicillin-binding proteins (PBPs) on the cell wall during bacterial mucopeptide synthesis. Cephalexin is used for the treatment of infection-causing bacteria that may induce ear, respiratory, urinary tract, and skin infections. Bacteria that are defenseless against Cephalexin may include Streptococcus pneumonia, Staphylococcus aureus, E. coli, and Haemophilus influenza. Cephalexin is also referred to as Keflex (brand name), and it does not relieve viral infections such as flu or colds.
Use of the ampicillin-type side chain conveys oral activity to cephalexin. Whereas it no longer has an activating side chain at C-3 and, as a consequence, is somewhat less potent, it does not undergo metabolic deactivation and, thus, maintains potency. It is rapidly and completely absorbed from the GI tract and has become quite popular. Somewhat puzzling is the fact that the use of the ampicillin side chain in the cephalosporins does not result in a comparable shift in antimicrobial spectrum. Cephalexin, like the other first-generation cephalosporins is active against many Gram-positive aerobic cocci but is limited against Gram-negative bacteria. It is a widely used drug, particularly against Gram-negative bacteria causing urinary tract infections, Gram-positive infections (Staphyl ococcus aureus, Streptococcus pneumoni ae and Streptococcus pyogenes) of soft tissues, pharyngitis, and minor wounds.
