• The age, weight and renal function of the patient; as shown below.

The duration of therapy should be determined by the type of infection and the response of the patient, and should generally be as short as possible.

Some infections require longer periods of treatment (see section 4.4 regarding prolonged therapy). 250 mg to 500 mg every 8 hours or 750 mg to 1 g every 12 hours.

Acute cystitis may be treated with 3 g twice daily for one day. 500 mg every 8 hours, 750 mg to 1 g every 12 hours. For severe infections 750 mg to 1 g every 8 hours for 10 days. 2 g orally, single dose 30 to 60 minutes before

750 mg to 1 g twice daily in combination with a proton pump inhibitor (e.g. omeprazole, lansoprazole) and another antibiotic (e.g. Lyme disease (see section 4.4) Early stage: 500 mg to 1 g every 8 hours up to a maximum of 4 g/day in divided doses for 14 days (10 to 21 days) Late stage (systemic involvement): 500 mg to 2 g every 8 hours up to a maximum of 6 g/day in divided doses for 10 to 30 days.

• Alteration of PBPs, which reduce the affinity of the antibacterial agent for the target.

Impermeability of bacteria or efflux pump mechanisms may cause or contribute to bacterial resistance, particularly in Gram-negative bacteria. MIC breakpoints for amoxicillin are those of the European Committee on Antimicrobial Susceptibility Testing (EUCAST) version 5.0.

1 Wild type Enterobacteriaceae are categorised as susceptible to aminopenicillins.

Some countries prefer to categorise wild type isolates of E. When this is the case, use the MIC breakpoint S ? 0.5 mg/L.

2 Most staphylococci are penicillinase producers, which are resistant to amoxicillin.

Methicillin resistant isolates are, with few exceptions, resistant to all beta-lactam agents.

3 Susceptibility to amoxicillin can be inferred from ampicillin.

Susceptibility inferred from the MIC of ampicillin. 6 Breakpoints are based on intravenous administration. Beta-lactamase positive isolates should be reported resistant.

7 Beta lactamase producers should be reported resistant.

8 Susceptibility to amoxicillin can be inferred from benzylpenicillin.

9 The breakpoints are based on epidemiological cut-off values (ECOFFs), which distinguish wild-type isolates from those with reduced susceptibility. 10 The non-species related breakpoints are based on doses of at least 0.5 g x 3or 4 doses daily (1.5 to 2 g/day).

The prevalence of

resistance

As necessary, expert advice should accord amoxicillin be sought when the local prevalence of resistance is such that the utility of the agent in at least some types of infections is questionable.

In vitro susceptibility of micro-organisms to Amoxicillin. Beta-hemolytic streptococci (Groups A, B, C and G) Listeria monocytogenes. Species for which acquired resistance may be a problem. Inherently resistant organisms † Enterococcus faecium † Acinetobacter spp.

(many strains of Bacteroides fragilis are resistant). † Natural intermediate susceptibility in the absence of acquired mechanism of resistance.

? Almost all S.aureus are resistant to amoxilcillin due to production of penicillinase. In addition, all methicillin-resistant strains are resistant to amoxicillin. Amoxicillin fully dissociates in aqueous solution at physiological pH. It is rapidly and well absorbed by the oral route of administration.

Following oral administration, amoxicillin is approximately 70% bioavailable. The time to peak plasma concentration (T max ) is approximately one hour. The pharmacokinetic results for a study, in which an amoxicillin dose of 250 mg three times daily was administered in the fasting state to groups of healthy volunteers are presented below. In the range 250 to 3000 mg the bioavailability is linear in proportion to dose (measured as C max and AUC).

The absorption is not influenced by simultaneous food intake.

Haemodialysis can be used for elimination of amoxicillin. About 18% of total plasma amoxicillin is bound to protein and the apparent volume of distribution is around 0.3 to 0.4 l/kg. Following intravenous administration, amoxicillin has been found in gall bladder, abdominal tissue, skin, fat, muscle tissues, synovial and peritoneal fluids, bile and pus.

Amoxicillin does not adequately distribute into the cerebrospinal fluid.

From animal studies there is no evidence for significant tissue retention of drug-derived material. Amoxicillin, like most penicillins, can be detected in breast milk (see section 4.6).

Amoxicillin has been shown to cross the placental barrier (see section 4.6). Amoxicillin is partly excreted in the urine as the inactive penicilloic acid in quantities equivalent to up to 10 to 25% of the initial dose.

The major route of elimination for amoxicillin is via the kidney. Amoxicillin has a mean elimination half-life of approximately one hour and a mean total clearance of approximately 25 l/hour in healthy subjects. Approximately 60 to 70% of the amoxicillin is excreted unchanged in urine during the first 6 hours after administration of a single 250 mg or 500 mg dose of amoxicillin.

Various studies have found the urinary excretion to be 50-85% for amoxicillin over a 24 hour period.

Concomitant use of probenecid delays amoxicillin excretion (see section 4.5). The elimination half-life of amoxicillin is similar for children aged around 3 months to 2 years and older children and adults.

For very young children (including preterm newborns) in

the

The total serum clearance of amoxicillin decreases proportionately with decreasing renal function (see sections 4.2 and 4.4).

Hepatically impaired patients should be dosed with caution and hepatic function monitored at regular intervals. Non-clinical data reveal no special hazard for humans based on studies of safety pharmacology, repeated dose toxicity, genotoxicity and toxicity to reproduction and development. Carcinogenicity studies have not been conducted with amoxicillin.

Amoxicillin belongs to the beta-lactam class of antibiotics and is approved to treat bacterial infections, including

Amoxicillin is one of the most commonly prescribed antibiotics. It’s similar to penicillin and can kill a wide variety of bacteria including Streptococcus species, Listeria monocytegenes, Enterococcus, Haemophilus influenzae, some E. coli, Actinomyces, Clostridial species, Shigella, Salmonella, and Corynebacteria .

This antibiotic belongs to a specific class of drugs called beta-lactams. Beta-lactam antibiotics such as amoxicillin work by binding proteins and inhibiting certain processes in bacterial cells.

This causes the cell walls to break down and destroys the bacteria, a process called bactericidal killing.
