- Cefaclor
- Anti-Bacterial Agents
- Bacterial Infections
Cefaclor is a bactericidal antibiotic recommended for treating diverse types of infections. This review aims to comprehensively assess the pharmacokinetic (PK) data on cefaclor in humans.Google Scholar, PubMed, Cochrane Library, and EBSCO databases were systematically performed to identify all the relevant studies containing at least one reported PK parameter of cefaclor.Cefaclor shows the linear PK profile as the area under the plasma concentration-time curve from 0 to t (AUC0-t) and maximum plasma concentration (Cmax) increase in a dose-dependent manner. The AUC0-t of cefaclor in the rice diet was found to be higher than that of bread food, i.e. 19.9 ± 2.6 ug/ml.hr vs 15.4 ± 4 ug/ml.hr. The AUC in paediatrics during the fed state was significantly higher compared to that in adults. Patients with renal impairments showed a Cmax 2.2 times higher than that of normal subjects. A significant increase in Cmax was depicted among individuals following a vegetarian diet in comparison with the non-vegetarian diet. Moreover, cefaclor exhibits time-dependent killing above the minimum inhibitory concentration (MIC < 2 ug), favouring its use in treating infections caused by specific pathogens.This systematic review summarises all the reported PK parameters of cefaclor in healthy and diseased subjects in the literature. This data can help practitioners in adjusting cefaclor doses among different diseases and populations to avoid drug interactions and adverse effects.

- Erysipelas
- Cellulitis
- Anti-Bacterial Agents
This study systematically evaluated and ranked the efficacy of first- and second-line antibiotics antibiotic options for the clinical management of cellulitis and erysipelas through a network meta-analysis approach. From inception to July 04, 2024, a search for relevant randomized clinical trials (RCTs) was carried out using several databases. Antibiotics including azithromycin, cefaclor, cephalexin, cloxacillin, erythromycin, cephalexin plus trimethoprim-sulfamethoxazole, cephalexin plus placebo, flucloxacillin, clindamycin, ceftriaxone, penicillin, roxithromycin, and pristinamycin were assessed regarding cure rate, the eradication of baseline pathogens, diarrhea or vomiting, and rash. In total, 10 RCTs with 1,936 cellulitis or erysipelas patients were eligible for inclusion. There were no significant differences in the cure rates for cellulitis among the antibiotics analysed, with cefaclor demonstrating the most favorable profile for curative outcomes. In terms of side effects, ceftriaxone was identified as the least likely to induce diarrhea or vomiting. For erysipelas, pristinamycin showed the most promising results in achieving cure rates. Although a comparison of the three antibiotics revealed no significant differences in rash as a side effect in erysipelas, pristinamycin was observed to carry the highest risk for rash. Our findings indicate no significant differences in cure rates among antibiotics for cellulitis. However, ceftriaxone had the fewest gastrointestinal side effects. Pristinamycin showed the highest cure rates for erysipelas but with a higher risk of rash. Future research should focus on optimizing antibiotic selection for cellulitis and erysipelas.
