If you have ever been prescribed antibiotics for a bacterial infection, you have probably been given amoxicillin or Augmentin (amoxicillin clavulanate) at one time or another. If your child has ever needed antibiotics, both may have been prescribed. Amoxicillin is often the first antibiotic prescribed for common infections like ear infections and strep throat. It is typically used in young children because it is effective against many common childhood bacterial infections and doesn't have many severe side effects. By adding a beta-lactamase blocker to amoxicillin, Augmentin is able 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. 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. Another, even more pressing concern is that using broad spectrum antibiotics can lead to antibiotic resistance. A broad-spectrum semisynthetic antibiotic similar to ampicillin except that its resistance to gastric acid permits higher serum levels with oral administration. Amoxicillin is commonly prescribed with clauvanic acid (a beta lactamase inhibitor) as it is susceptible to beta-lacatamase degradation.

In this lesson, you will learn about the antibiotic amoxicillin, the gram positive and gram negative bacteria that amoxicillin targets. Amoxicillin is a penicillin derived antibiotic used against bacteria. treat a broader range of both Gram-positive and Gram-negative infections. The molecular formula is C16H19N3O5S•3H2O and the molecular weight is 419.45. The chemical structure is: Amoxicillin acts by inhibiting bacterial cell wall synthesis. Lack of bacterial cell wall results in death due to lysis of bacteria. So amoxicillin is useful only for actively growing and cell wall synthesizing bacteria. Food does not interfere with absorption of amoxicillin. It crosses the placenta; small amounts are distributed into breast milk. Amoxicillin is excreted mainly by kidney and by hepatic metabolism. Its excretion can be delayed by concomitant administration of probenecid. Amoxicillin is a penicillin derived antibiotic used against bacteria. It is used to treat many different types of infections caused by bacteria, such as tonsillitis, bronchitis, pneumonia, gonorrhoea, and ear, nose, throat, skin or urinary infections. Amoxicillin was discovered by scientists at Beecham Research Laboratories in 1972. The narrow spectrum of antimicrobial activity of the penicillins, led to the search for derivatives of penicillin which could treat a wider range of infections. The first important step forward was the development of ampicillin. Ampicillin had a broader spectrum of activity than either of the original penicillins and allowed doctors to treat a broader range of both Gram-positive and Gram-negative infections. Further developments led to amoxicillin, with improved duration of action.
