Cefalexin, also spelled cephalexin, is an antibiotic that can treat a number of bacterial infections. [4] It kills gram-positive and some gram-negative bacteria by disrupting the growth of the bacterial cell wall. [4] Cefalexin is a β-lactam antibiotic within the class of first-generation cephalosporins. [4]
β-Lactam antibiotics are indicated for the prevention and treatment of bacterial infections caused by susceptible organisms. At first, β-lactam antibiotics were mainly active only against gram-positive bacteria, yet the recent development of broad-spectrum β-lactam antibiotics active against various gram-negative organisms has increased their usefulness.
cephalexin: Keflex: H V: Gram-positive: Activity against penicillinase-producing, methicillin-susceptible staphylococci and streptococci (though they are not the drugs of choice for such infections). No activity against methicillin-resistant staphylococci or enterococci. [citation needed]
This is a list of common β-lactam antibiotics—both administered drugs and those not in clinical use—organized by structural class. Antibiotics are listed alphabetically within their class or subclass by their nonproprietary name. If an antibiotic is a combination drug, both ingredients will be listed.
Oral Antibiotics: Oral antibiotics like dicloxacillin or cephalexin may be prescribed for bacterial folliculitis. Antifungal Medications: ...
Cephalosporins are a broad class of bactericidal antibiotics that include the β-lactam ring and share a structural similarity and mechanism of action with other β-lactam antibiotics (e.g. penicillins, carbapenems and monobactams). [1]
The following is a list of antibiotics. The highest division between antibiotics is bactericidal and bacteriostatic. ... Keflex: Cephalosporins (Second generation)
The next step is to give her antibiotics. We most commonly use cephalexin or amoxicillin-clavulanate acid, but if many dogs are resistant to them, local veterinarians may make another choice.
