mononucleosis develop a rash during amoxicillin therapy |

|
|
| Adverse
Reactions |

|
1% to 10%: Gastrointestinal: Gastric upset, diarrhea, nausea
<1%: Rash, pseudomembranous colitis, agranulocytosis, mildly increased

|
Reconstituted suspension is stable for 10 days when stored in the

| Mechanism of
Action |
|
|
Interferes with bacterial cell wall synthesis during active multiplication
causing cell wall death and resultant bactericidal activity against susceptible
bacteria |

|
|
| Pharmacodynamics/Kinetics |
|
|

Bioavailability: 80% to 98%
Half-life: 65 minutes, prolonged in patients with impaired renal function
Time to peak serum concentration: Area under the serum concentration time
curve is 40% higher for bacampicillin than after equivalent ampicillin doses
