Clamentin is a brand name for a combination antibiotic that typically contains amoxicillin and clavulanic acid. Amoxicillin is a penicillin-type antibiotic that helps to fight bacterial infections, while clavulanic acid inhibits beta-lactamase enzymes that some bacteria produce to resist antibiotics. This combination enhances the effectiveness of amoxicillin against a broader range of bacteria. Clamentin is commonly used to treat various infections, including respiratory tract infections, urinary tract infections, and skin infections.
