The pharmacokinetics of ceftriaxone were investigated in six healthy mainland Chinese adults (four males and two females). A single 1.0-g dose was administered intravenously or intramuscularly in a two-way crossover design. Plasma and saliva samples were collected on 11 occasions between 0 and 36 h after dosing. Ceftriaxone was not detected in any saliva samples. The mean volume of distribution...

PURPOSE In our previous study, ceftriaxone, a beta-lactam antibiotic, elicited antinociceptive effects in the chronic constriction injury (CCI) of neuropathic pain. In this study, we assessed apoptosis and oxidative stress in the spinal cord of neuropathic rats treated with ceftriaxone. METHODS 45 male Wistar rats were divided as naïve, sham, normal saline-treated CCI rats, and CCI animals tr...

OBJECTIVES Reduced susceptibility to extended-spectrum cephalosporins in Neisseria gonorrhoeae has, to date, been associated with three alterations: a mosaic penA allele encoding the penicillin-binding protein 2 (PBP2); A-del-mtrR, an adenine deletion in the mtrR promoter; and penB, comprising mutated alleles of PorBIb. In this study, we examined an association between reduced susceptibility to...

To evaluate ceftriaxone for the treatment of shigellosis, 94 adult males with acute dysentery were randomly assigned to receive ceftriaxone (1 g), ampicillin (4 g), or saline placebo intravenously in single doses in a double-blind design. Stool cultures were positive for Shigella dysenteriae in 52 patients, S. flexneri in 38 patients, and other species in 4 patients. Both ceftriaxone and ampici...

Treatment of pneumococcal meningitis has become problematic because of the emergence of penicillin- and cephalosporin-resistant strains and because of the concern that dexamethasone therapy might reduce penetration of antibiotics into the cerebrospinal fluid (CSF). We addressed these issues with our rabbit meningitis model by studying two pneumococcal isolates that were resistant to penicillin ...

BACKGROUND Community-acquired pneumonia (CAP) is a major cause of death and morbidity worldwide. Treatment is centred on antibiotics with ceftriaxone and amoxicillin-clavulanate being some of the most commonly prescribed agents. OBJECTIVE To compare treatment outcomes and costs in patients receiving either of these two antibiotics at Witbank Hospital (WH). METHODS A total of 200 randomly se...

The chemical stability of ceftriaxone for injection reconstituted with water was studied at different storage conditions by a validated stability-indicating ion-pair liquid chromatographic method. The study was performed on ceftriaxone for injection samples obtained from two pharmaceutical laboratories, at three different temperatures: 23 oC ± 2 oC, + 8 oC ± 1 oC and 20 oC ± 0.5 oC, over 26 day...

Cerebral hypoperfusion is associated with cognitive decline in ageing, mild cognitive impairment, vascular type dementia, and Alzheimer’s disease. The mechanisms leading to such neurological impairments are still uncertain. Although several mechanisms have been proposed as contributing factors leading to neuronal injury, glutamate excitotoxicity seems to be the relevant one. Recently, it was fo...
