| INDICATIONS
Amoxicillin; clavulanate potassium is indicated in the treatment
of infections caused by susceptible strains of the designated
organisms in the conditions listed below.
Lower Respiratory Tract Infections: Caused by b-lactamase-producing
strains of Haemophilus influenzae and Moraxella (Branhamella)
catarrhalis.
Otitis Media: Caused by b-lactamase-producing strains of Haemophilus
influenzae and Moraxella (Branhamella) catarrhalis.
Sinusitis: Caused by b-lactamase-producing strains of Haemophilus
influenzae and Moraxella (Branhamella) catarrhalis.
Skin and Skin Structure Infections: Caused by b-lactamase-producing
strains of Staphylococcus aureus, Escherichia coli and Klebsiella
spp.
Urinary Tract Infections: Caused by b-lactamase-producing strains
of Escherichia coli, Klebsiella spp. and Enterobacter spp.
While amoxicillin; clavulanate potassium is indicated only
for the conditions listed above, infections caused by ampicillin-susceptible
organisms are also amenable to amoxicillin; clavulanate potassium
treatment due to its amoxicillin content. Therefore, mixed infections
caused by ampicillin-susceptible organisms and b-lactamase-producing
organisms susceptible to amoxicillin; clavulanate potassium
should not require the addition of another antibiotic. Because
amoxicillin has greater in vitro activity against Streptococcus
pneumoniae than does ampicillin or penicillin, the majority
of S. pneumoniae strains with intermediate susceptibility to
ampicillin or penicillin are fully susceptible to amoxicillin
and amoxicillin; clavulanate potassium. (See CLINICAL PHARMACOLOGY,
Microbiology.)
Bacteriological studies, to determine the causative organisms
and their susceptibility to amoxicillin; clavulanate potassium,
should be performed together with any indicated surgical procedures.
Therapy may be instituted prior to obtaining the results from
bacteriological and susceptibility studies to determine the
causative organisms and their susceptibility to amoxicillin;
clavulanate potassium when there is reason to believe the infection
may involve any of the b-lactamase-producing organisms listed
above. Once the results are known, therapy should be adjusted,
if appropriate.
DOSAGE AND ADMINISTRATION
Oral Solution and Chewable Tablets
Pediatric Patients
Based on the amoxicillin component, amoxicillin; clavulanate
potassium should be dosed as follows.
Neonates and Infants Aged <12 weeks (3 months): Due to incompletely
developed renal function affecting elimination of amoxicillin
in this age group, the recommended dose of amoxicillin; clavulanate
potassium is 30 mg/kg/day divided q12h, based on the amoxicillin
component. Clavulanate elimination is unaltered in this age
group. Experience with the 200 mg/5 ml formulation in this age
group is limited and, thus, use of the 125 mg/5 ml oral suspension
is recommended.
