Cephalexin uptake by human MATE1-expressing human embryonic kidney 293 cells exhibits saturable kinetics with K(m) = 5.9 mM and a bell-shaped pH profile with a maximum at pH 7.0. Cephalexin results in overestimation of glucose concentration, but only in the samples that contain the highest antimicrobial concentration (2,400microg/mL) and only for the tablet. Cephalexin increases the activity of superficial mucous cells and orifice mucous cells of gastric glands, and inhibits the activity of cervix mucous cells.

Cephalexin causes a slight prolongation of 1-stage prothrombin time (PT) and activated partial thromboplastin time (PTT) and slight decrease in fibrinogen concentration in healthy dogs. Cephalexin causes a significant increase in 1-stage PT and activated PTT, amoxicillin causes a significant increase in activated PTT, and enrofloxacin causes a significant decrease in fibrinogen concentration. Cephalexin results in high numbers of E. coli producing plasmid-mediated CMY-2 β-lactamase at the end of the treatment period in dogs.
