  • Renal impairment:The dose is adjusted if the creatinine clearance is less than 30ml/min.
  • Adults and children (40 kg and above): Creatinine clearance of 10-30 ml/min: 500 mg/125 mg two times a day. Creatinine clearance of less than 10 ml/min: 500 mg/125 mg once a day
  • Hemodialysis: 500 mg/125 mg once a day in addition to 500 mg/125 mg as dialysis is done that is repeated at the end as concentrations in serum reduce

Children less than 40 kg

Creatinine clearance of 10-30 ml/min: 15 mg/3.75 mg/kg two times a day

Creatinine clearance of less than 10 ml/min: 15 mg/3.75 mg/kg once a day.

Chemical composition

Augmentin 625 contains tow active ingredients. These are:

  • 500 mg amoxicillin
  • 125 mg clavulanic acid as potassium clavulanate

Mechanism of Action (MOA)

Typhoid bacteriaAmoxicillin is a penicillin that is semi-synthetic or a beta-lactam. It works by inhibiting the action of one or more enzymes known as the penicillin-binding proteins(PBPs). These enzymes are involved in the synthesis of bacterial peptidoglycan a component of the bacterial cell wall. When taken orally, amoxicillin prevents the formation of peptidoglycan preventing the formation of the cell wall. This leads to the formation of a weakened cell wall, causing the bacteria to lyse and die eventually.

Resistant bacteria to amoxicillin produce beta-lactamases that degrade it preventing it from being effective. Such bacteria are not susceptible to amoxicillin. To ensure that the effect of amoxicillin remains, clavulanic acid is added.

Clavulanic acid a beta-lactam has a structure related to that of penicillin. Clavulanic acid inactivates the enzymes, beta-lactamases, as a result, the action of amoxicillin is enhanced. Clavulanic acid does not have anti-bacterial effects when taken alone.
