| Background |
Cefalexin is a cephalosporin antibiotic. |
| Biological Activity |
Cephalexin is a potent, orally active and the first-generation cephalosporin antibiotic. Cephalexin kills gram-positive and some gram-negative bacteria by disrupting the growth of the bacterial cell wall[1-2]. |
| In Vivo |
After a single intravenous administration of cephalexin(5 mg/kg)，Mate1(-/-)mice showed higher plasma concentrations of cephalexin than wild-type [Mate1(+/+)] mice. The urinary excretion of cephalexin for 60 min was significantly reduced，and the renal concentration was markedly increased in Mate1(-/-)mice compared with Mate1(+/+)mice. The renal clearance of cephalexin in Mate1(-/-)mice was approximately 60% of that in Mate1(+/+)mice and seemed to be near the creatinine clearance.[1] Cephalexin increases the activity of superficial mucous cells and orifice mucous cells of gastric glands，and inhibits the activity of cervix mucous cells. A simultaneous administration of ethanol and cephalexin causes atrophic changes in gastric glands，and thereby strong reduction of mucous cells activity.[2] |
| Animal Experiment |
The Wistar rat males weighing approximately 200 g were administered 20% ethanol ad libitum during 10 days，cephalexin in the dose of 42 mg/24 h，and simultaneously ethanol and cephalexin in the above-mentioned doses. After 10 days the animals were decapitated and stomach specimens were taken from the major curvature region for examinations. [2] |
