Amoxicillin and clavulanate potassium for oral suspension is an oral antibacterial combination consisting of the semisynthetic antibiotic amoxicillin and the "ß-lactamase inhibitor, clavulanate potassium (the potassium salt of clavulanic acid). Amoxicillin is an analog of ampicillin, derived from the basic penicillin nucleus, 6-aminopenicillanic acid.
Clavulanic acid is produced by the fermentation of Streptomyces clavuligerus. It is a ß-lactam structurally related to the penicillins and possesses the ability to inactivate a wide variety of ß-lactamases by blocking the active sites of these enzymes. Clavulanic acid is particularly active against the clinically important plasmid-mediated ß-lactamases frequently responsible for transferred drug resistance to penicillins and cephalosporins.
Amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL is indicated for the treatment of pediatric patients with recurrent or persistent acute otitis media due to S. pneumoniae (penicillin MICs ≤2 mcg/mL), H. influenzae (including β-lactamase–producing strains), or M. catarrhalis (including β-lactamase–producing strains) characterized by the following risk factors:
- antibiotic exposure for acute otitis media within the preceding 3 months, and either of the following:
- –daycare attendance
[See CLINICAL PHARMACOLOGY, Microbiology.]
NOTE: Acute otitis media due to S. pneumoniae alone can be treated with amoxicillin. Amoxicillin and Clavulanate Potassium for oral suspension, 600 mg/42.9 mg per 5 mL is not indicated for the treatment of acute otitis media due to S. pneumoniae with penicillin MIC ≥4 mcg/mL.
Therapy may be instituted prior to obtaining the results from bacteriological studies when there is reason to believe the infection may involve both S. pneumoniae (penicillin MIC ≤2 mcg/mL) and the β-lactamase–producing organisms listed above.
To reduce the development of drug-resistant bacteria and maintain the effectiveness of amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL and other antibacterial drugs, amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

Place of Antibiotics in the Postoperative Acute Lithiasic Cholecystitis [Recruiting]
Assess whether postoperative antibiotics after cholecystectomy for acute lithiasic
cholecystitis little or moderately severe, is effective and therefore justified.
The main objective is to compare the occurrence of postoperative infectious complications
including surgical site infections (SSI) and remote infections after early cholecystectomy
(performed within 5 days after onset of symptoms) for acute lithiasic cholecystitis (ALC)
little or moderately serious (without organ dysfunction) with and without postoperative
The secondary objectives are:
- Rates of infectious complications according to duration of preoperative antibiotic
- Influence of surgical drainage after surgery for occurrence of postoperative infectious
- Analysis of the nature of infectious complications (surgical site infections, remote
surgical site infections)
- Comparison of germs found in the bile during the postoperative infectious complications
- Duration of hospitalization
- Readmission rate for surgical site infections
- Rate of reoperation for surgical site infection
- Overall mortality rate at 30 days
- Mortality rates specific to 30 days
Assessing the Necessity of Prescribing Antibiotics (Clavulin or Clindamycin Versus Placebo) Post-peritonsillar Abscess Drainage [Recruiting]
This study aims to look at the necessity for prescribing antibiotics post-drainage of
peritonsillar abscesses (PTA). This will be a single-blinded randomized-control trial with
two arms - patients receiving placebo versus those receiving a seven day course of oral
Amoxicillin-Clavulanic acid. The main objective measure will be to assess if there is
resolution of the peri-tonsillar abscess and there has been no reaccumulation. Patients will
be blinded to whether they receive placebo or amoxicillin-clavulanic acid. Patients will be
phoned after 7 days to assess if their symptoms have resolved via an over the phone
questionnaire. Anaerobic and aerobic cultures will be obtained.

failure rate, defined as symptomatic Urinary Tract Infection (UTI) through Test of Cure
(TOC) on Day 12-14, as subjects who continue to take antibiotics for an additional 5 days
(standard course therapy). To determine if short-course therapy compared to standard course
therapy results in similar numbers of children with gastrointestinal colonization of
antimicrobial resistant Escherichia coli (E. coli) and Klebsiella pneumonia (K. pneumoniae).
