Medically reviewed on May 1, To reduce the development of amoxicillin tablets ingredients 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 bacteria. Chemically, amoxicillin tablets ingredients, it is 2 S ,5 R ,6 R [ R - - amino p -hydroxyphenyl acetamido]-3,3-dimethyloxothiaazabicyclo[3.
It may be represented structural formula as: Capsules of Amoxicillin are intended for oral administration. Amoxicillin tablets ingredients capsule of Amoxicillin with blue cap and pink body, contains mg or amoxicillin tablets ingredients Amoxicillin as the trihydrate. Amoxicillin is stable in the presence of gastric acid and is rapidly absorbed after oral administration.
The effect of food on the absorption of Amoxicillin from the tablets and suspension of Amoxicillin has been partially investigated. The mg and mg formulations have been studied only when administered at the start of a light meal, amoxicillin tablets ingredients. However, food effect studies have not been performed with the mg and mg formulations. Amoxicillin diffuses readily into most body tissues and fluids, amoxicillin tablets ingredients, with the exception of brain and spinal fluid, except when meninges are inflamed.
The half-life of Amoxicillin is Most of the Amoxicillin is excreted unchanged in the urine; its excretion can be delayed by concurrent administration of probenecid. Orally administered doses of mg and mg Amoxicillin capsules result in average peak blood levels 1 to 2 hours after administration in the range of 3.
Dosing was at the start of a light meal following an overnight fast. Detectable serum levels are observed up to 8 hours after an orally administered dose of Amoxicillin. Following a 1 gram dose and common names of antibiotics alternatives a special skin window technique to determine levels of the antibiotic, it was noted that therapeutic levels were found in the interstitial fluid.
Amoxicillin is similar to ampicillin in its bactericidal action against susceptible organisms during the stage of active multiplication. It acts through the inhibition of biosynthesis of cell wall mucopeptide. Enterococcus faecalis Staphylococcus spp. Quantitative methods are used to determine antimicrobial amoxicillin tablets ingredients inhibitory concentrations MICs.
These MICs provide estimates of the susceptibility of bacteria to antimicrobial compounds, amoxicillin tablets ingredients. 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, amoxicillin tablets ingredients.
Ampicillin is sometimes used to predict susceptibility of S. Amoxicillin tablets ingredients MIC values should be interpreted according to the following criteria: For Gram-Positive Aerobes Enterococcus. Amoxicillin powder should be used to determine susceptibility. These interpretive criteria are based on the recommended doses for respiratory tract infections.
For Gram-Negative Aerobes Enterobacteriaceae. These interpretive standards are applicable only to broth microdilution test with H. 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.
Standardized susceptibility test procedures require the use of laboratory control microorganisms to control the technical aspects of the laboratory procedures, amoxicillin tablets ingredients. Standard ampicillin powder should provide the following MIC values: This quality control range is applicable to only H.
This quality control range is applicable to only S. 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, amoxicillin tablets ingredients. This procedure uses paper disks impregnated with 10 mcg ampicillin amoxicillin tablets ingredients test the susceptibility of microorganisms, except S.
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-Negative Aerobes Enterobacteriacea e.
These interpretive standards are applicable only to disk diffusion susceptibility tests with H. As with standard dilution techniques, disk diffusion susceptibility test procedures require the use of laboratory control microorganisms. The 10 mcg ampicillin disk should provide the following zone diameters in these laboratory test quality control strains: In vitro alternatives to prostate cancer treatment testing methods and diagnostic products currently available for determining minimum inhibitory concentrations MICs and zone sizes have not been standardized, validated, or approved for testing H.
Culture and susceptibility testing should be obtained in patients who fail amoxicillin tablets ingredients therapy. If clarithromycin resistance is found, amoxicillin tablets ingredients, a non-clarithromycin-containing regimen should be used.
Amoxicillin, in combination with clarithromycin plus lansoprazole as triple therapy, is indicated for the treatment of patients with H. Amoxicillin, in combination with lansoprazole delayed-release capsules as dual therapy, is indicated for the treatment of patients with H.
To reduce the development of drug-resistant bacteria and maintain amoxicillin tablets ingredients effectiveness of Amoxicillin and other antibacterial drugs, Amoxicillin should be used only to treat or prevent infections that are proven amoxicillin drug facts 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 amoxicillin tablets ingredients such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy. Indicated surgical procedures should be performed. A history of allergic reaction to any of the penicillins is a contraindication. Clostridium difficile associated diarrhea CDAD has been reported with use of nearly all antibacterial agents, including Amoxicillin, and may range in severity from mild diarrhea to fatal colitis.
Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. Hypertoxin producing strains of C. CDAD must be considered in all patients who present with diarrhea following antibiotic use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents. Appropriate fluid and electrolyte management, protein supplementation, amoxicillin tablets ingredients, antibiotic treatment of C.
The possibility of superinfections with mycotic or bacterial pathogens should be kept in mind during therapy. If superinfections penicillin allergy cross reactivity cephalosporins, Amoxicillin should be discontinued and appropriate therapy instituted.
A high percentage of patients with mononucleosis who receive ampicillin develop an erythematous skin rash. Thus, ampicillin-class antibiotics should not be administered to patients with mononucleosis. Prescribing Amoxicillin in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.
As with any potent drug, periodic assessment of renal, hepatic, and hematopoietic function should be made during prolonged therapy.
All patients with gonorrhea should have a serologic test for syphilis at the time of diagnosis. Patients treated with Amoxicillin tablets ingredients should have a follow-up serologic test for syphilis after 3 months. Probenecid decreases the renal tubular secretion of Amoxicillin. Amoxicillin tablets ingredients use of Amoxicillin and probenecid may result in increased and prolonged blood levels of Amoxicillin.
Chloramphenicol, macrolides, amoxicillin tablets ingredients, sulfonamides, and tetracyclines may interfere with the bactericidal effects of penicillin.
This has been demonstrated in vitro ; however, amoxicillin tablets ingredients, the clinical significance of this interaction is not well documented. Following administration of ampicillin to pregnant women, a transient decrease in plasma concentration of total conjugated estriol, estriol-glucuronide, conjugated estrone, and estradiol has been amoxicillin tablets ingredients. This effect may also occur with Amoxicillin.
Long-term studies in animals have not been performed to evaluate carcinogenic potential. Studies to detect mutagenic potential of Amoxicillin alone have not been conducted; however, the following information is available from tests on a 4: Amoxicillin and potassium clavulanate was non-mutagenic in the Ames bacterial mutation assay, and the yeast gene conversion assay.
Amoxicillin and potassium clavulanate was weakly positive in the mouse lymphoma assay, but the trend toward increased mutation frequencies in this assay occurred at doses that were also associated with decreased cell survival. Amoxicillin and potassium clavulanate was negative in the mouse micronucleus amoxicillin tablets ingredients, and in the dominant lethal assay in mice, amoxicillin tablets ingredients. Potassium clavulanate alone was tested in the Ames bacterial mutation assay and in the mouse micronucleus test, and was negative in each of these assays.
Reproduction studies have been performed in mice and rats at doses up to 10 times the human dose and have revealed no evidence of impaired fertility or harm to the fetus due to Amoxicillin.
There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Oral ampicillin-class antibiotics are poorly absorbed during labor, amoxicillin tablets ingredients.
Studies in guinea pigs showed that intravenous administration of ampicillin slightly decreased the uterine tone and frequency of contractions but moderately increased the height and duration of contractions. However, it is not known whether use of Amoxicillin in humans during labor or delivery has immediate or delayed adverse effects on the fetus, prolongs the duration of labor, or increases the likelihood that forceps delivery or other obstetrical intervention or resuscitation of the newborn will be necessary.
Penicillins have been shown to be excreted in human milk. Amoxicillin use by nursing mothers may lead to sensitization of infants. Caution should be exercised when Amoxicillin is administered to a nursing woman. Because of incompletely developed renal function amoxicillin tablets ingredients neonates and young infants, the elimination of Amoxicillin may be delayed. An analysis of clinical studies of Amoxicillin was conducted to determine whether subjects aged 65 and over respond differently from younger subjects.
This analysis and other reported clinical experience have not identified differences in responses between the elderly and younger patients, amoxicillin tablets ingredients, but a greater sensitivity of some older individuals cannot be ruled out. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function.
Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.
Amoxicillin tablets ingredients may be taken every 8 hours or every 12 hours, amoxicillin tablets ingredients, depending on the strength of the product prescribed, amoxicillin tablets ingredients. Amoxicillin tablets ingredients should be counseled that antibacterial drugs, including Amoxicillin, should only be used to treat bacterial infections. They do not treat viral infections e.
