Teva amoxicillin
The lowest limit of quantification obtained by UV detection was 50ng/ml, but the elution times for both AMO and internal standard were 31.8 and 32.8 min, respectively, much longer than those reported herein (14). The method of Chulavatnatol & Charles was described only for the measurement of amoxicillin in urine (19). A simple high-performance liquid chromatographic method involving protein precipitation and ultraviolet detection at 220 nm was reported by Hoizey et al. for the simultaneous determination of AMO and clavulanic acid in human plasma (15). Unfortunately, the LOQ obtained for AMO was 635 m g/ml, even higher than in our method (1 m g/ml). Other more complicated extraction procedures such as solid-phase extraction have also been reported (17, 18, 24-26). Nevertheless, solid-phase extraction procedures are laborious and require SPE cartridges, increasing the cost of the analysis. In order to improve sensitivity, a column switching ion-pair reversed phase liquid chromatographic system with a post column derivatization method has been used by Carlqvist & Westerlund (23). However, their assay, where the limit of quantification was 10ng/ml, has been carried out with no internal standard. In addition the method was complex due to the post column derivatization step. Their retention time was also longer for the analyte (approximately 10 min as compared to our 4 min) and additionally was not used for a pharmacokinetic study in humans where a large number of samples were analyzed. Derivatization of AMO to a fluorescent compound showed similar sensitivity and slightly longer retention time (4.5 min for AMO), but does involve a complex chromatography system including electrochemical detection (20). and Mascher & Kikuta have satisfactory limits of quantification but do not utilize an internal standard, which is required for an HPLC method meeting GLP guidelines (20, 22). reported the determination of AMO using LC-MS-MS detection. Mass spectrometers, however, are expensive and not readily available. Furthermore, the solid-phase extraction procedure employed need laborious sample pre-treatment and requires SPE cartridges, increasing the cost of the analysis (26). The method presented here is less sensitive than many other available assays, i.e., 1 m g/ml. However, this level of sensitivity was sufficient to perform the bioequivalence study. The pharmacokinetic study was done in 8 hours and the resulting value of AUC 0- ¥? was less than 20% higher than that of AUC 0-8 for both formulations (12 and 13.9% for Amoxicilina and Amoxil respectively), as recommended by the regulatory agency. Later samples (12 and 24h after the administration of the drug) were taken and analyzed, but no better estimation of AUC 0- ¥? was observed and the differences between the values remain virtually the same. The choice of Cefadroxil as an internal standard for AMO was based on the presence of similar functional groups in both structures in addition to their similarity in terms of elemental compositions and chemical behavior. Several wavelengths (225-330nm) were evaluated and 229 nm produced the best results in terms of selectivity and sensitivity. Considering the fact that the present method involves a shorter running time and a simple sample preparation process, it may be used in similar studies as a time and cost effective alternative to other available methods. The validated HPLC method employed here proved to be simple, fast, reliable, selective and sensitive enough to be used in clinical pharmacokinetic studies of AMO in humans. The median T max and C max values for both oral formulations were similar to those reported in the literature. The present study shows that Amoxicilina 500mg capsules was bioequivalent to Amoxil® capsules 500mg, in terms of both the rate and extent of absorption, as assessed by the appearance of 90% CI for both AUC 0-8h and C max ratios within the 80-125% interval proposed by the Food and Drug Administration .

Treatment Over the Counter Prevention Symptoms Common Cold Flu Related Illnesses. If you or your child has ever needed to take an antibiotic for a bacterial infection, there's a good chance the medication prescribed was either amoxicillin or Augmentin (amoxicillin clavulanate). A common assumption about these two medications is that Augmentin is simply a stronger version of amoxicillin but that isn't quite accurate. Augmentin contains a second active ingredient, which makes it more appropriate for treating certain infections than others. The same holds true for amoxicillin and, to make the distinctions between the drugs even hazier, there are a few infections that both treat equally effectively. Ultimately, the antibiotic a doctor prescribes will depend on the type of illness being treated and the bacteria responsible for it. Amoxicillin is often the first antibiotic prescribed for common bacterial infections, particularly those that cause illness in children, such as ear, nose, and throat infections, including tonsillitis. This antibiotic also is the first drug of choice for: Urinary tract infections Helicobacter pylori associated with ulcers Lyme disease. (Note that although amoxicillin can kill many of the same bacteria as penicillin, it is less effective than penicillin against Streptococcus pneumococcus, the bacteria commonly associated with meningitis and systemic bacteremia.) The side effects of amoxicillin tend to be relatively mild, which is another reason it's often prescribed for kids. The most common ones include rash, vaginal itching, and a dark or "hairy tongue. ? ??Digestive side effects such as nausea and vomiting can occur, but are much more common with Augmentin. As with penicillin, there is a risk of an allergic reaction to amoxicillin in those predisposed to it. Symptoms include rash, itching, swelling of the face, tongue, and/or throat, trouble breathing, and dizziness. It's vital a doctor take a medical history before prescribing amoxicillin to determine if a patient has a known history of allergy to antibiotics. Augmentin is amoxicillin combined with a beta-lactamase inhibitor called clavulanate, an ingredient that blocks the enzymes that contribute to antibiotic resistance. ? ? The addition of a beta-lactamase blocker to amoxicillin allows Augmentin to overcome resistance to harder-to-treat bacteria, broadening the spectrum of infections it can treat. It is for this reason that Augmentin is referred to as a broad-spectrum antibiotic . Augmentin can treat the same bacteria as amoxicillin, but also is effective against certain harder-to-treat infections, ? ? including: Sinus infections Ear infections Bacterial infections associated with COPD Skin abscesses Diabetic foot. It should be noted there are a few infections for which amoxicillin and Augmentin are prescribed equally: Pyelonephritis (kidney infections) Erysipelas, a type of skin infection Chronic strep "carriers" The most common side effect of Augmentin is diarrhea. Some people may also experience nausea, vomiting, yeast infections, and rash. If you have an infection and don't necessarily know which bacteria is causing it, it may seem to make sense to use an antibiotic that would kill the most bugs. ? ? Antibiotics used indiscriminately may destroy "good" bacteria along with "bad," thereby altering the body's natural flora and allowing even worse bacteria to proliferate. Another, even more pressing concern is that using broad-spectrum antibiotics can lead to antibiotic resistance. Resistance develops when an antibiotic you are using are unable to fully eradicate a bacteria in your body, ? ? often because you stopped treatment before you were supposed to. When this happens, a few mutated bacteria may survive, some of which may be naturally resistant to the antibiotic you were taking. Because you didn't " hit the infection hard enough," these survivors now have the opportunity to multiply and become the dominant strain. As such, the next time you develop an infection, the antibiotic will not work anywhere near as well. If this happens with broad-spectrum antibiotic like Augmentin, you will be at greater risk of having multiple types of drug resistance. With a "narrow-spectrum" antibiotic like amoxicillin, the consequence may be less severe. Complete the entire course even if you feel better. Take an antibiotic only if your doctor deems it necessary. Whether you're prescribed amoxicillin, Augmentin, or another antibiotic, it's not so much the "strength" of the drug you should be concerned about; it's all about the safety, efficacy, and appropriateness of treatment. People are sometimes surprised, and even taken aback, when they are given amoxicillin for a serious infection such as pneumonia.
