Research Excerpts

Pharmacokinetics

ExcerptReferenceRelevance
" CS-834 was administered orally to healthy male volunteers at single doses of 50, 100, 200, and 400 mg and at a multiple dose of 150 mg three times a day for 7 days to investigate its safety and pharmacokinetic profiles."( Safety and pharmacokinetics of CS-834, a new oral carbapenem antibiotic, in healthy volunteers.

Bioavailability

ExcerptReferenceRelevance
" Other studies were conducted to examine the effect of food intake on the bioavailability of CS-834 and also the effect of the coadministration of probenecid on the pharmacokinetics of CS-834."( Safety and pharmacokinetics of CS-834, a new oral carbapenem antibiotic, in healthy volunteers.

Dosage Studied

ExcerptRelevanceReference
" To investigate the possibility that CS-834 may be the first carbapenem usable in an oral dosage form, its in vitro antibacterial activity (as R-95867) and in vivo antibacterial activity were compared with those of cefpodoxime proxetil, cefditoren pivoxil, cefdinir, ofloxacin, imipenem, and amoxicillin."( In vitro and in vivo antibacterial activities of CS-834, a new oral carbapenem.
