The new semi-synthetic oral cephalosporin, CGP 9,000, has been evaluated in a large number of hospitalized patients with urinary infections. A total of 57 of these patients suffering from concomitant diabetes was matched with an equal number of non-diabetic patients. Patients were treated for 10 days with either 500 mg or 1.0 g CGP, or 1.0 g cephalexin. The predominant pathogens isolated were E. coli, Strep. faecalis, Proteus mirabilis and Klebsiella spp. Comparison of the results showed that the eradication rate was similar in diabetic and non-diabetic patients and there were no significant differences between the three treatment groups. There was a similar improvement in pyuria, and therapeutic response was equally as good in diabetic patients on 500 mg CGP 9,000 per day as in non-diabetic patients and in the other treatment groups. No unwanted effects on renal function were observed in the high-risk diabetic group.

Background: Managing drug-food interactions may help to achieve the optimal action and safety profile of β-lactam antibiotics.
Methods: We conducted a systematic review with meta-analyses in adherence to PRISMA guidelines for 32 β-lactams. We included 166 studies assessing the impact of food, beverages, antacids or mineral supplements on the pharmacokinetic (PK) parameters or PK/pharmacodynamic (PK/PD) indices.

A specific and rapid high performance liquid chromatographic (HPLC) method with UV detection (254 nm) was developed for the determination of cefroxadine in human plasma. The sample extraction was performed by a simple procedure, vortexing and centrifugation of sample following addition of 60% trichloroacetic acid. Cephalexin was used as an internal standard (I.

We compared the antimicrobial activity of commercially available oral cephem agents, cefaclor (CCL), cefroxadine (CXD), cefdinir (CFDN), cefixime (CFIX), cefpodoxime (CPDX), cefteram (CFTM), cefcapene (CFPN), and cefditoren (CDTR), against Streptococcus pneumoniae, Haemophilus influenzae, Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus, Streptococcus agalactiae, Streptococcus pyogenes, and ESBL-producing bacteria isolated from clinical materials in Kansai Medical University Hospital between 2002 and 2003. Based on the Pharmacokinetics/Pharmacodynamics (PK/PD) theory, we determined the concentration of each agent at which the time above MIC (TAM) value was 40% or more, and calculated the rate of efficacy against each type of bacteria. In S.
