Amoxicillin is an antibiotic often used for the treatment of a number of bacterial infections. These include middle ear infection, strep throat, pneumonia. 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 bacteria. Amoxicillin (Amoxil, Moxatag, Larotid) is an antibiotic that belongs to a class of antibiotics called penicillins. Common infections that amoxicillin is used to treat include middle ear infections, tonsillitis, laryngitis, bronchitis, pneumonia, skin, gonorrhea, and urinary tract infections. Amoxicillin may cause false positive results with certain diabetic urine testing products (cupric sulfate-type). This drug may also affect the results of certain lab tests. Make sure laboratory. Amoxicillin is a penicillin antibiotic that fights bacteria. Amoxicillin is used to treat many different types of infection caused by bacteria, such as tonsillitis, bronchitis, pneumonia, gonorrhea, and infections of the ear, nose, throat, skin, or urinary tract. Amoxicillin generic and brand name. The drug is available under generic name Amoxicillin and commonly marketed under the brand name Amoxil. The drug Amoxicillin was developed by Beecham and initially manufactured and marketed by SmithKline Beecham. Before taking amoxicillin and clavulanic acid, tell your doctor and pharmacist if you are allergic to amoxicillin (Amoxil, Trimox, Wymox), clavulanic acid, penicillin, cephalosporins, any other medications, or any of the ingredients in amoxicillin and clavulanic acid preparations. Amoxicillin is similar to penicillin in its bactericidal action against susceptible bacteria during the stage of active multiplication. It acts through the inhibition of cell wall biosynthesis that leads to the death of the bacteria. Mechanism of action. Amoxicillin like other penicillins, inhibit thepenicillin binding proteins (PBPs specifically PBP-1A ), which are transmembrane surface enzymes that catalyse the cross linking (transpeptidation) between the peptidoglycans in the bacterial cell wall. This amino group, present on both ampicillin and amoxicillin, helps these antibiotics pass through the pores of the outer membrane of Gram-negative bacteria, such as E. coli, Proteus mirabilis, Salmonella enterica, and Shigella.
