Potassium clavulanate is widely used in combination with certain antibiotics, such as amoxicillin, to enhance their effectiveness against bacterial infections. It works by inhibiting beta-lactamase enzymes, which are produced by some bacteria to resist antibiotics. This combination is commonly prescribed for treating infections like sinusitis, pneumonia, urinary tract infections, and skin infections. It is particularly effective against bacteria that have developed resistance to standard antibiotics. The addition of potassium clavulanate ensures that the antibiotic can work more efficiently, making it a crucial component in combating resistant bacterial strains.
