Which drug classification is commonly known for treating bacterial infections?

The classification known for treating bacterial infections is antibiotics. Antibiotics are specifically designed to combat bacteria, targeting their growth and reproduction. They work by either killing the bacteria directly or inhibiting their ability to grow and multiply, which helps the body's immune system eliminate the infection more effectively.

The other classifications serve different purposes: analgesics are used to relieve pain, antivirals are aimed at treating viral infections, and antifungals target fungal infections. Each of these categories has a distinct mechanism of action and is used for specific types of pathogens, further highlighting the unique role of antibiotics in managing bacterial infections.
