    Amoxicillin mechanism


    Amoxicillin is used in the treatment of a number of infections, including acute otitis media, streptococcal pharyngitis, pneumonia, skin infections, urinary tract infections, Salmonella infections, Lyme disease, and chlamydia infections. Children with acute otitis media who are younger than 6 months of age are generally treated with amoxicillin or other antibiotic. Although most children with acute otitis media who are older than two years old do not benefit from treatment with amoxicillin or other antibiotic, such treatment may be helpful in children younger than two years old with acute otitis media that is bilateral or accompanied by ear drainage. In the past, amoxicillin was dosed three times daily when used to treat acute otitis media, which resulted in missed doses in routine ambulatory practice. There is now evidence that two times daily dosing or once daily dosing has similar effectiveness. Amoxicillin is recommended as the preferred first-line treatment for community-acquired pneumonia in adults by the National Institute for Health and Care Excellence, either alone (mild to moderate severity disease) or in combination with a macrolide. It is effective as one part of a multi-drug regimen for treatment of stomach infections of Helicobacter pylori. 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.

    Lesson on the antibiotic amoxicillin, what bacteria amoxicillin targets, the mechanism of action of amoxicillin, contraindications of amoxicillin. Amoxicillin is in the class of beta-lactam antibiotics. Beta-lactams act by binding to penicillin-binding proteins that inhibit a. Amoxicillin Amoxil, Moxatag, and Larotid is a penicillin antibiotic prescribed to treat a variety of bacterial infections such as sinusitis, laryngitis, strep throat, pneumonia, and urinary tract infections.

    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. Penicillin (aminopenicillin) Gram-positive: Streptococcus spp., Enterococcus spp., Listeria monocytogenes Gram-negative: H. coli, Proteus mirabilis, Salmonella spp., Shigella spp. Exerts bactericidal activity via inhibition of bacterial cell wall synthesis by binding one or more of the penicillin binding proteins (PBPs). Exerts bacterial autolytic effect by inhibition of certain PBPs related to the activation of a bacterial autolytic process. Penicillins produce time-dependent killing Cmax: 7.5mcg/ml; Oral bioavailability: 80%; Half-life: 1-1.3h; Table 6 anemia, thrombocytopenia, neutropenia, agranulocytosis seizures nephrotoxicity, interstitial nephritis transient increases in transaminases Jarisch-Herxheimer Reaction (fever, chills, sweating, tachycardia, hyperventilation, flushing, and myalgia) 500mg po q12h or 250-500mg po q8h or 875mg po q12h Pediatric: Acenocoumarin increased risk of bleeding; Allopurinol higher probablility of amoxicillin rash; Contraceptives - decreased contraceptive effectiveness; Live Typhoid Vaccine - decreased immunological response to the typhoid vaccine; Methotrexate methotrexate toxicity; Probenecid - increased amoxicillin levels; Warfarin increased risk of bleeding Category B: No evidence of risk in humans but studies inadequate.
