  2. Handle this product with great care to avoid exposure, taking all recommended precautions.

    Amoxicillin is a broad-spectrum semi-synthetic penicillin bactericidal in action.

Amoxicillin predominately inhibits cell wall synthesis in susceptible bacteria. Amoxicillin has a unique mode of action which directly and irreversibly disrupts existing cell wall peptidoglycan rather than newly forming peptidoglycan of the divisory septal wall as with other members of the penicillin family.

After the administration of Duphamox, Amoxicillin is widely absorbed and widely distributed in the body and high levels are found in kidney, urine, liver and bile.
