Activity of LY333328 in experimental meningitis caused by a Streptococcus pneumoniae strain susceptible to penicillin.

In a rabbit model of Streptococcus pneumoniae meningitis single doses of 10 and 2.5 mg of the glycopeptide LY333328 per kg of body weight reduced bacterial titers in cerebrospinal fluid (CSF) almost as rapidly as ceftriaxone at 10 mg/kg/h (changes in log CFU, -0.29 +/- 0.

Comparative pharmacokinetics of dirithromycin and erythromycin in normal volunteers with special regard to accumulation in polymorphonuclear leukocytes and in saliva.

Objective: In a randomized cross-over study, we assessed pharmacokinetics and intracellular concentrations in polymorphonuclear leukocytes (PMN) and saliva of erythromycin and erythromycylamine, the active metabolite of dirithromycin.

Methods: Ten healthy volunteers received 1 g erythromycin b.i.

Clinical efficacy of dirithromycin in pharyngitis and tonsillitis.

A total of 193 patients with streptococcal pharyngitis/tonsillitis received 500 mg dirithromycin once daily and 196 patients 250 mg erythromycin four times daily for ten days in a double-blind, parallel-group multicentre study. In the dirithromycin treatment group, 97 (50.3%) patients completed the study and were evaluated for efficacy analysis, and 99/196 (50.

Loracarbef versus penicillin V in the treatment of streptococcal pharyngitis and tonsillitis.

Ten-day, double-blind, randomized, parallel treatment regimens of loracarbef (200 mg capsule twice daily or 15 mg/kg/day oral suspension in two divided doses up to a maximum of 375 mg/day; n = 169) and penicillin V (250 mg capsule four times daily or 20 mg/kg/day suspension in four divided doses up to a maximum of 500 mg/day; n = 175) were compared in the treatment of group A beta-haemolytic streptococcal (GABHS) pharyngitis and tonsillitis. Post-therapy clinical responses were similar for evaluable patients in both treatment groups: 97.4% of the loracarbef group (101/115 patients cured and 11/115 improved) and 96.
