Ampicillin and alternatives.

Bioavailability of ampicillin (anhydrous) and ampicillin trihydrate.

Ampicillin susceptibility and ampicillin-induced killing rate of Escherichia coli.

The killing rate induced by ampicillin was determined in 20 strains of Escherichia coli. The apparent generation rate constant for each E. coli showed a characteristic concentration-dependent course. This course can be mathematically described and is determined by four parameters. Three of these parameters determine the speed of the process, and the fourth parameter determines a minimal concent...

Effects of ampicillin-amikacin and ampicillin-rifampin on enterococci.

Fifty-seven clinical isolates of enterococcus were tested for susceptibility to 10 antibiotics in a microtiter broth dilution system. Amoxicillin, ampicillin, vancomycin, and rifampin inhibited all strains at concentrations easily achievable in blood. Resistance to rifampin developed rapidly. Of the aminoglycosides, gentamicin was most active, followed in decreasing order by tobramycin, amikaci...

Thrombophlebitis with diazepam and ampicillin.

Infusion thrombophlebitis is a common but illunderstood complication (4, 6) of intravenouS infusions. Further drugs given in infusions may cause phlebitis. Confilicting reports are available about the incidence of phlebitis with diazepam, (1,2,5). Even commonly used antibiotics like ampicillin, in infusion increases the incidence of thrombophlebitis and worst offenders are cephalosporins, (5). ...

In vitro comparison of ampicillin-chloramphenicol and ampicillin-cefotaxime against 284 Haemophilus isolates.

Since November 1982 at the Sainte-Justine Hospital in Montreal, ampicillin and cefotaxime were used in association as initial treatment (greater than or equal to 48 h) for childhood bacterial meningitis. In this report is described the in vitro interaction of the new regimen in comparison with that of the previous ampicillin-chloramphenicol combination against 284 Haemophilus isolates. Among th...
