Amoxicillin is stable in the presence of gastric acid and is rapidly absorbed after oral administration. Amoxicillin diffuses readily into most body tissues and fluids, with the exception of brain and spinal fluid, except when meninges are inflamed. The half-life of amoxicillin is 61.3 minutes. Most of the amoxicillin is excreted unchanged in the urine; its excretion can be delayed by concurrent administration of probenecid. In blood serum, amoxicillin is approximately 20% protein-bound. Orally administered doses of 250 mg and 500 mg amoxicillin capsules result in average peak blood levels 1 to 2 hours after administration in the range of 3.5 mcg/mL to 5 mcg/mL and 5.5 mcg/mL to 7.5 mcg/mL, respectively.

INDICATIONS AND USAGE

displayName: INDICATIONS & USAGE SECTION
FDA Article Code: 34067-9

To reduce the development of drug-resistant bacteria and maintain the effectiveness of amoxicillin and other antibacterial drugs, amoxicillin 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. Amoxicillin is indicated in the treatment of infections due to susceptible (ONLY β-lactamase–negative) strains of the designated microorganisms in the conditions listed below:

Infections of the ear, nose, and throat –due to
Streptococcus spp. (α- and β-hemolytic strains only),
Streptococcus pneumoniae, Staphylococcus spp., or
H. influenzae.


Infections of the genitourinary tract – due to
E. coli, P. mirabilis, or
E. faecalis.


Infections of the skin and skin structure – due to
Streptococcus spp. (α- and β-hemolytic strains only),
Staphylococcus spp., or
E. coli.


Infections of the lower respiratory tract due to Streptococcus spp. (α- and β-hemolytic strains only),
S. pneumoniae, Staphylococcus spp., or
H. influenzae. Gonorrhea, acute uncomplicated (ano-genital and urethral infections) due to
N. gonorrhoeae (males and females).
H. pylori eradication to reduce the risk of duodenal ulcer recurrence Triple therapy: Amoxicillin /clarithromycin/lansoprazole

Amoxicillin, in combination with clarithromycin plus lansoprazole as triple therapy, is indicated for the treatment of patients with
H. pylori infection and duodenal ulcer disease (active or 1-year history of a duodenal ulcer) to eradicate
H. pylori. Eradication of
H. pylori has been shown to reduce the risk of duodenal ulcer recurrence. (See
CLINICAL STUDIES and
DOSAGE AND ADMINISTRATION.
) Dual therapy: Amoxicillin/lansoprazole

Amoxicillin, in combination with lansoprazole delayed-release capsules as dual therapy, is indicated for the treatment of patients with
H. pylori infection and duodenal ulcer disease (active or 1-year history of a duodenal ulcer)
who are either allergic or intolerant to clarithromycin or in whom resistance to clarithromycin is known or suspected. (See the clarithromycin package insert, MICROBIOLOGY.) Eradication of
H. pylori has been shown to reduce the risk of duodenal ulcer recurrence. (See
CLINICAL STUDIES and
DOSAGE AND ADMINISTRATION.
) Indicated surgical procedures should be performed.

A history of allergic reaction to any of the penicillins is a contraindication.

WARNINGS

displayName: WARNINGS SECTION
FDA Article Code: 34071-1

SERIOUS AND OCCASIONALLY FATAL HYPERSENSITIVITY (ANAPHYLACTIC) REACTIONS HAVE BEEN REPORTED IN PATIENTS ON PENICILLIN THERAPY. ALTHOUGH ANAPHYLAXIS IS MORE FREQUENT FOLLOWING PARENTERAL THERAPY, IT HAS OCCURRED IN PATIENTS ON ORAL PENICILLINS. THESE REACTIONS ARE MORE LIKELY TO OCCUR IN INDIVIDUALS WITH A HISTORY OF PENICILLIN HYPERSENSITIVITY AND/OR A HISTORY OF SENSITIVITY TO MULTIPLE ALLERGENS. THERE HAVE BEEN REPORTS OF INDIVIDUALS WITH A HISTORY OF PENICILLIN HYPERSENSITIVITY WHO HAVE EXPERIENCED SEVERE REACTIONS WHEN TREATED WITH CEPHALOSPORINS. BEFORE INITIATING THERAPY WITH AMOXICILLIN, CAREFUL INQUIRY SHOULD BE MADE CONCERNING PREVIOUS HYPERSENSITIVITY REACTIONS TO PENICILLINS, CEPHALOSPORINS, OR OTHER ALLERGENS. IF AN ALLERGIC REACTION OCCURS, AMOXICILLIN SHOULD BE DISCONTINUED AND APPROPRIATE THERAPY INSTITUTED.
SERIOUS ANAPHYLACTIC REACTIONS REQUIRE IMMEDIATE EMERGENCY TREATMENT WITH EPINEPHRINE. OXYGEN, INTRAVENOUS STEROIDS, AND AIRWAY MANAGEMENT, INCLUDING INTUBATION, SHOULD ALSO BE ADMINISTERED AS INDICATED.
Pseudomembranous colitis has been reported with nearly all antibacterial agents, including amoxicillin, and may range in severity from mild to life-threatening. Therefore, it is important to consider this diagnosis in patients who present with diarrhea subsequent to the administration of antibacterial agents. Treatment with antibacterial agents alters the normal flora of the colon and may permit overgrowth of clostridia. Studies indicate that a toxin produced by
Clostridium difficile is a primary cause of “antibiotic-associated colitis.”
After the diagnosis of pseudomembranous colitis has been established, appropriate therapeutic measures should be initiated. Mild cases of pseudomembranous colitis usually respond to drug discontinuation alone. In moderate-to-severe cases, consideration should be given to management with fluids and electrolytes, protein supplementation, and treatment with an antibacterial drug clinically effective against
C. difficile colitis.

ADVERSE REACTIONS


id: 6368132c-9897-6291-e053-2a91aa0a5364
displayName: ADVERSE REACTIONS SECTION
FDA Article Code: 34084-4

As with other penicillins, it may be expected that untoward reactions will be essentially limited to sensitivity phenomena. They are more likely to occur in individuals who have previously demonstrated hypersensitivity to penicillins and in those with a history of allergy, asthma, hay fever, or urticaria. The following adverse reactions have been reported as associated with the use of penicillins:
Gastrointestinal:
Nausea, vomiting, diarrhea, and hemorrhagic / pseudomembranous colitis.
Onset of pseudomembranous colitis symptoms may occur during or after antibiotic treatment. (See
WARNINGS.
)

Hypersensitivity Reactions:
Serum sickness–like reactions, erythematous maculopapular rashes, erythema multiforme, Stevens-Johnson syndrome, exfoliative dermatitis, toxic epidermal necrolysis, acute generalized exanthematous pustulosis, hypersensitivity vasculitis and urticaria have been reported.
NOTE: These hypersensitivity reactions may be controlled with antihistamines and, if necessary, systemic corticosteroids. Whenever such reactions occur, amoxicillin should be discontinued unless, in the opinion of the physician, the condition being treated is life-threatening and amenable only to amoxicillin therapy.
Liver:
A moderate rise in AST (SGOT) and/or ALT (SGPT) has been noted, but the significance of this finding is unknown. Hepatic dysfunction including cholestatic jaundice, hepatic cholestasis and acute cytolytic hepatitis have been reported.

Renal:
Crystalluria has also been reported (see
OVERDOSAGE )

Hemic and Lymphatic Systems:
Anemia, including hemolytic anemia, thrombocytopenia, thrombocytopenic purpura, eosinophilia, leukopenia, and agranulocytosis have been reported during therapy with penicillins. These reactions are usually reversible on discontinuation of therapy and are believed to be hypersensitivity phenomena.

Central Nervous System:
Reversible hyperactivity, agitation, anxiety, insomnia, confusion, convulsions, behavioral changes, and/or dizziness have been reported rarely.

Miscellaneous:
Tooth discoloration (brown, yellow, or gray staining) has been rarely reported. Most reports occurred in pediatric patients. Discoloration was reduced or eliminated with brushing or dental cleaning in most cases.

Combination therapy with clarithromycin and lansoprazole:


In clinical trials using combination therapy with amoxicillin plus clarithromycin and lansoprazole, and amoxicillin plus lansoprazole, no adverse reactions peculiar to these drug combinations were observed. Adverse reactions that have occurred have been limited to those that had been previously reported with amoxicillin, clarithromycin, or lansoprazole.

OVERDOSAGE


id: 6368132c-989a-6291-e053-2a91aa0a5364
displayName: OVERDOSAGE SECTION
FDA Article Code: 34088-5

In case of overdosage, discontinue medication, treat symptomatically, and institute supportive measures as required. If the overdosage is very recent and there is no contraindication, an attempt at emesis or other means of removal of drug from the stomach may be performed. A prospective study of 51 pediatric patients at a poison-control center suggested that overdosages of less than 250 mg/kg of amoxicillin are not associated with significant clinical symptoms and do not require gastric emptying.
3
Interstitial nephritis resulting in oliguric renal failure has been reported in a small number of patients after over-dosage with amoxicillin. Crystalluria, in some cases leading to renal failure, has also been reported after amoxicillin overdosage in adult and pediatric patients. In case of overdosage, adequate fluid intake and diuresis should be maintained to reduce the risk of amoxicillin crystalluria. Renal impairment appears to be reversible with cessation of drug administration. High blood levels may occur more readily in patients with impaired renal function because of decreased renal clearance of amoxicillin. Amoxicillin may be removed from circulation by hemodialysis.

H. pylori

eradication to reduce the risk of duodenal ulcer recurrence:
Randomized, double-blind clinical studies performed in the United States in patients with H. pylori and duodenal ulcer disease (defined as an active ulcer or history of an ulcer within 1 year) evaluated the efficacy of lansoprazole in combination with amoxicillin capsules and clarithromycin tablets as triple 14-day therapy, or in combination with amoxicillin capsules as dual 14-day therapy, for the eradication of
H. pylori. Based on the results of these studies, the safety and efficacy of 2 different eradication regimens were established:

Triple therapy:
Amoxicillin 1 gram twice daily/clarithromycin 500 mg twice daily/lansoprazole 30 mg twice daily.

Dual therapy:
Amoxicillin 1 gram three times daily/lansoprazole 30 mg 3 times daily.
All treatments were for 14 days.
H. pylori eradication was defined as 2 negative tests (culture and histology) at 4 to 6 weeks following the end of treatment.
Triple therapy was shown to be more effective than all possible dual therapy combinations. Dual therapy was shown to be more effective than both monotherapies. Eradication of
H. pylori has been shown to reduce the risk of duodenal ulcer recurrence.

FDA Article Code: 42229-5

Dilution Techniques: Quantitative methods are used to determine antimicrobial minimum inhibitory concentrations (MICs). These MICs provide estimates of the susceptibility of bacteria to antimi-crobial compounds. The MICs should be determined using a standardized procedure. Standardized procedures are based on a dilution method
1 (broth or agar) or equivalent with standardized inoculum concentrations and standardized concentrations of
ampicillin powder. Ampicillin is sometimes used to predict susceptibility of
S. pneumoniae to amoxicillin; however, some intermediate strains have been shown to be susceptible to amoxicillin. Therefore,
S. pneumoniae susceptibility should be tested using amoxicillin powder.
The MIC values should be interpreted according to the following criteria:
For Gram-Positive Aerobes:
Enterococcus
MIC (mca /mL)
Interpretation ≤ 8 ≥ 16 Resistant (R)

Staphylococcus
a
Interpretation ≤ 0.25 Susceptible (S) ≥ 0.5 Resistant (R)
NOTE: These interpretive criteria are based on the recommended doses for respiratory tract infections. For Gram-Negative Aerobes: Streptococcus (except S. pneumoniae) S. pneumoniae
b from non-meningitis sources. (Amoxicillin powder should be used to determine susceptibility.)
MIC (mca /mL)
Interpretation ≤ 0.25 Susceptible (S) 0.5 to 4 Intermediate (I) ≥ 8 Resistant (R)
MIC (mca /mL)
Interpretation ≤ 2 Susceptible (S) 4 Intermediate (I) ≥ 8 Resistant (R)
A report of “Susceptible” indicates that the pathogen is likely to be inhibited if the antimicrobial compound in the blood reaches the concentrations usually achievable. A report of “Intermediate” indicates that the result should be considered equivocal, and, if the microorganism is not fully susceptible to alternative, clinically feasible drugs, the test should be repeated. This category implies possible clinical applicability in body sites where the drug is physiologically concentrated or in situations where high dosage of drug can be used. This category also provides a buffer zone, which prevents small uncontrolled technical factors from causing major discrepancies in interpretation. A report of “Resistant” indicates that the pathogen is not likely to be inhibited if the antimicrobial compound in the blood reaches the concentrations usually achievable; other therapy should be selected. Standardized susceptibility test procedures require the use of laboratory control microorganisms to control the technical aspects of the laboratory procedures. Standard
ampicillin powder should provide the following MIC values:
Using
amoxicillin to determine susceptibility:
Diffusion Techniques: Quantitative methods that require measurement of zone diameters also provide reproducible estimates of the susceptibility of bacteria to antimicrobial compounds. One such standardized procedure
2 requires the use of standardized inoculum concentrations. This procedure uses paper disks impregnated with 10 mcg ampicillin to test the susceptibility of microorganisms, except
S. pneumoniae, to amoxicillin. Interpretation involves correlation of the diameter obtained in the disk test with the MIC for
ampicillin.
Reports from the laboratory providing results of the standard single-disk susceptibility test with a 10 mcg ampicillin disk should be interpreted according to the following criteria: For gram-positive aerobes: Staphylococcus
