Cloxacillin, a semisynthetic penicillin is a potent inhibitor of most penicillinase-producing Staphylococci. Use of high doses of Cloxacillin for 6 weeks is recommended for the treatment of infective endocarditis caused by methicillin-susceptible Staphylococcus aureus (MSSA). Here, we report a case of Cloxacillin-induced agranulocytosis in a patient treated for MSSA native tricuspid valve endoc...

Rabbits with established staphylococcal endocarditis, injected twice at an interval of 2 h with either 0.5 mg of cloxacillin per kg or saline, were sacrificed 2.5 h after the second injection. Vegetations were excised, weighed, and cultured, and ultrathin sections were prepared and examined by light microscopy, transmission electron microscopy, and scanning electron microscopy. Several affected...

Although early antibiotic treatment of patients with septic arthritis eradicates bacteria, joint destruction commonly results from the unregulated host inflammatory responses to infection. The spin trap compound phenyl-N-tert-butyl nitrone (PBN) has been shown to have both anti-inflammatory and antioxidant effects. The aim of this study was to assess the effect of combined systemic administrati...

1University of Gezira, Wad Medani, Sudan. 2University of Khartoum, Khartoum, Sudan. New Halfa Hospital, New Halfa, Sudan. Received: 09/10/02; accepted: 14/09/03 ABSTRACT We carried out a prospective, randomized, controlled clinical trial to evaluate the clinical efficacy of ceftriaxone and ampicillin/cloxacillin prophylaxis in decreasing the frequency of post-caesarean section infection-related...

Pharmacokinetic and pharmacodynamic interactions between Org 10172 (intravenous bolus injection of 3,250 anti-Xa units), which is a low-molecular-weight heparinoid, cloxacillin (500 mg orally four times daily for 3 days), and ticarcillin (4,000 mg intravenously four times daily for 2 days) were evaluated in two separate studies with healthy male volunteers (n = 18). Both cloxacillin and ticarci...

On the assumption of the theory that the sulfone of a penam derivative should effectively act as a suicide substrate against beta-lactamases to which the parent compound is a poor substrate, the action of cloxacillin sulfone on four different types of beta-lactamases was studied. As we expected, cloxacillin sulfone showed strong mechanism-based irreversible inactivation against type Ib penicill...

Cloxacillin, ampicillin, cephaloridine, kanamycin, and polymyxin B were administered singly in the dialysis fluid of patients having peritoneal dialysis for chronic renal failure. Therapeutic blood levels could be attained with all the drugs by the end of 12 hours of dialysis, using a concentration in the dialysis fluid which did not produce any local toxic symptoms. Absorption rates across the...

BACKGROUND Various intramammary suspensions containing cloxacillin benzathine are registered for use in cattle as antibiotics for intramammary use at drying off. To ensure antibacterial efficacy, the glandular tissue concentration of an antimicrobial agent must be sufficient. Since the possibilities to measure concentrations in the different areas of the glandular tissue in vivo are very limite...

According to Gibaldi et al. (1968, 1970), the higher serum concentrations of penicillins and cephaloridine reached after administration of probenecid are due not only to slower renal elimination but also to an altered distribution in the body. To determine whether probenecid has a direct effect on the distribution of cloxacillin, the elimination and distribution of cloxacillin was studied in si...

Cloxacillin-resistant strains of Staphylococcus aureus were detected by their ability to grow on agar containing 1.6 mug./ml. of cloxacillin, a more reliable method than the disc-diffusion test. At Sefton General Hospital, Liverpool, between 1963 and 1965, there was an increase in the number of infections among in-patients that were caused by staphylococci resistant to cloxacillin despite the f...
