Question 3

How does Bacitracin work?

Accepted Answer

Mechanism of Action

Bacitracin belongs to a class of medications known as antibiotics. It works by interfering with the way bacteria build their cell walls. The cell wall is a critical outer layer that bacteria need to survive, maintain their shape, and protect themselves from their environment.

By preventing the formation of this wall, bacitracin stops the bacteria from reproducing and growing. This process helps the body's immune system clear the infection more effectively. Depending on the concentration used and the type of bacteria present, bacitracin can either stop the growth of bacteria or kill them directly.

Scope of Activity

It is important to understand how bacitracin interacts with different types of germs:

Targeted Bacteria: Bacitracin is primarily effective against gram-positive bacteria, such as staphylococci and streptococci, which are common causes of skin and eye infections.

Bacterial Infections Only: This medication only works against bacterial infections. It is not effective against infections caused by viruses (such as the common cold or herpes) or fungi (such as athlete's foot).

Local Treatment: When applied as an ointment or solution to the skin or eyes, the medication acts locally. This means it works directly at the site of a minor cut, scrape, or burn to prevent or treat an infection without being absorbed significantly into the rest of the body.

Ophthalmic use: Approved for the treatment of superficial infections of the eye, such as those affecting the conjunctiva or cornea. These formulations require a prescription.

Injectable use: Approved for intramuscular administration specifically for infants with staphylococcal pneumonia and empyema when the infection is caused by susceptible organisms.

Boxed Warning
