Amoxicillin tablet is a penicillin-type antibiotic that is effective against a range of bacterial infections. It works by inhibiting the growth of bacteria, making it a powerful tool in fighting infections like pneumonia, bronchitis, and infections of the ears, nose, throat, skin, and urinary tract. Due to its broad-spectrum activity and relatively mild side effects, amoxicillin is commonly prescribed, especially for children.

To understand how amoxicillin works, it's important to know a bit about bacterial cell walls. Bacteria have a rigid cell wall that protects them and gives them shape. The cell wall is made up of peptidoglycan, a substance that gives the wall its strength. Amoxicillin inhibits the enzymes involved in the formation of this peptidoglycan layer, weakening the cell wall and leading to the death of the bacteria.

This mode of action is highly effective against many types of bacteria, particularly those responsible for common infections. However, amoxicillin is not effective against viruses, such as the flu or the common cold, because viruses lack a cell wall.
