How Does Augmentin ES Work?
Augmentin ES contains two different medications,
amoxicillin and clavulanate potassium (also known as clavulanic acid, or simply clavulanate).
Amoxicillin belongs to a group of medications known as aminopenicillins, which is part of a larger group of medications known as beta-lactam antibiotics (named after the ring-like "lactam" structure of these antibiotics).
Amoxicillin works by stopping bacteria from making cell walls, which eventually causes the bacteria to die. However, many bacteria have developed a resistance to amoxicillin (and similar antibiotics) by producing enzymes called beta-lactamases. Beta-lactamases (produced by bacteria) break the beta-lactam ring, making amoxicillin (and similar antibiotics) ineffective.
The other component of Augmentin ES (clavulanate) is known as a beta-lactamase inhibitor. Clavulanate stops the bacterial enzymes from breaking down the amoxicillin molecule. Clavulanate itself has no significant antibacterial activity; it merely helps to prevent amoxicillin from being broken down by bacteria that would otherwise be resistant to amoxicillin. Essentially, clavulanate "augments" the activity of amoxicillin (hence the name Augmentin).
