Augmentin XR (Amoxicillin / Clavulanate Potassium) - Summary

 
 



AUGMENTIN XR SUMMARY

AUGMENTIN XR is an oral antibacterial combination consisting of the semisynthetic antibiotic amoxicillin (present as amoxicillin trihydrate and amoxicillin sodium) and the β-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.

AUGMENTIN XR Extended Release Tablets are indicated for the treatment of patients with community-acquired pneumonia or acute bacterial sinusitis due to confirmed, or suspected β-lactamase?producing pathogens (i.e., H. influenzae, M. catarrhalis, H. parainfluenzae, K. pneumoniae, or methicillin-susceptible S. aureus) and S. pneumoniae with reduced susceptibility to penicillin (i.e., penicillin MICs = 2 mcg/mL). AUGMENTIN XR is not indicated for the treatment of infections due to S. pneumoniae with penicillin MICs ≥ 4 mcg/mL. Data are limited with regard to infections due to S. pneumoniae with penicillin MICs ≥ 4 mcg/mL (see CLINICAL STUDIES).

Of the common epidemiological risk factors for patients with resistant pneumococcal infections, only age > 65 years was studied. Patients with other common risk factors for resistant pneumococcal infections (e.g., alcoholism, immune-suppressive illness, and presence of multiple co-morbid conditions) were not studied.

In patients with community-acquired pneumonia in whom penicillin-resistant S. pneumoniae is suspected, bacteriological studies should be performed to determine the causative organisms and their susceptibility when AUGMENTIN XR is prescribed.

Acute bacterial sinusitis or community-acquired pneumonia due to a penicillin-susceptible strain of S. pneumoniae plus a β-lactamase?producing pathogen can be treated with another AUGMENTIN® (amoxicillin/clavulanate potassium) product containing lower daily doses of amoxicillin (i.e., 500 mg every 8 hours or 875 mg every 12 hours). Acute bacterial sinusitis or community-acquired pneumonia due to S. pneumoniae alone can be treated with amoxicillin.

To reduce the development of drug-resistant bacteria and maintain the effectiveness of AUGMENTIN XR and other antibacterial drugs, AUGMENTIN XR 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.

Response of feline eosinophilic plaques and lip ulcers to amoxicillin trihydrate-clavulanate potassium therapy: a randomized, double-blind placebo-controlled prospective study. [2012]
In this study, we evaluated the treatment of feline eosinophilic plaques and lip ulcers with amoxicillin trihydrate-potassium clavulanate (Clavamox(®); Pfizer Animal Health). Nineteen cats with clinical and cytological findings consistent with eosinophilic plaques and/or lip ulcers were enrolled...

Single-dose extended-release azithromycin versus a 10-day regimen of amoxicillin/clavulanate for the treatment of children with acute otitis media. [2011.04]
OBJECTIVES: A randomized, double-blind, double-dummy, multicenter international study was conducted to assess the clinical and bacteriologic response, safety, and compliance of a single 60-mg/kg dose of azithromycin extended-release (ER) versus a 10-day regimen of amoxicillin/clavulanate 90/6.4 mg/kg per day in children with acute otitis media at high risk of persistent or recurrent middle ear infection... CONCLUSIONS: A single 60-mg/kg dose of azithromycin ER provides near equivalent effectiveness to a 10-day regimen of amoxicillin/clavulanate 90/6.4 mg/kg per day in the treatment of children with acute otitis media.

Amoxicillin/clavulanic acid-warfarin drug interaction: a randomized controlled trial. [2011.02]
AIMS: To investigate whether an interaction exists between amoxicillin/clavulanic acid (amoxiclav) and warfarin in patients treated with stable oral anticoagulant therapy... CONCLUSION: Amoxiclav did not modify anticoagulation in patients treated with stable warfarin therapy and without infection. (c) 2011 The Authors.

Azithromycin extended release vs amoxicillin/clavulanate: symptom resolution in acute sinusitis. [2010.01]
OBJECTIVE: The aim of the study was to compare early symptom resolution with a single 2-g dose of azithromycin extended release or 10 days of amoxicillin/clavulanate 875 mg/125 mg every 12 hours in patients with acute sinusitis... CONCLUSIONS: More patients randomized to azithromycin extended release experienced symptom resolution at day 5 than those randomized to amoxicillin/clavulanate, without experiencing differences in second antibiotic use at 28 days.

Fosfomycin in a single dose versus a 7-day course of amoxicillin-clavulanate for the treatment of asymptomatic bacteriuria during pregnancy. [2009.12]
The purpose of this paper was to compare the efficacy of a single dose of 3 g of fosfomycin to that of a 7-day regimen of amoxicillin-clavulanate in the treatment of asymptomatic bacteriuria during pregnancy. A randomised, prospective, interventional, analytical, longitudinal study was undertaken, in which the efficacy of two antibiotic regimens (one short and the other long) in the treatment of pregnant women with asymptomatic bacteriuria is compared...
