Types of Antibiotics

Explore different classes of antibiotics, their mechanisms of action, and common examples.


Penicillins

Penicillins are a group of antibiotics that are commonly used to treat bacterial infections. They work by interfering with the bacteria's cell wall synthesis, resulting in bacterial death. Penicillins are effective against a wide range of bacteria and are often used as a first-line treatment for various infections.

Cephalosporins

Cephalosporins are another class of antibiotics that are used to treat bacterial infections. They work in a similar way to penicillins by disrupting the bacterial cell wall synthesis. Cephalosporins are commonly prescribed for a variety of infections, including skin infections, urinary tract infections, and respiratory tract infections.

Macrolides

Macrolides are a group of antibiotics that are effective against a wide range of bacteria. They work by inhibiting bacterial protein synthesis, which prevents the bacteria from growing and multiplying. Macrolides are often used to treat respiratory infections, such as pneumonia and bronchitis, as well as skin infections and sexually transmitted infections.

Fluoroquinolones

Fluoroquinolones are a type of antibiotics that are commonly used to treat bacterial infections, especially those caused by gram-negative bacteria. They work by inhibiting bacterial DNA replication, which ultimately leads to bacterial death. Fluoroquinolones are often used to treat urinary tract infections, respiratory infections, and skin infections.

Tetracyclines

Tetracyclines are a group of antibiotics that are effective against a wide range of bacteria. They work by inhibiting bacterial protein synthesis, which prevents the bacteria from growing and multiplying. Tetracyclines are commonly used to treat acne, respiratory infections, and certain sexually transmitted infections.

Aminoglycosides

Aminoglycosides are a class of antibiotics that are effective against a variety of bacteria, especially gram-negative bacteria. They work by inhibiting bacterial protein synthesis, which ultimately leads to bacterial death. Aminoglycosides are often used to treat severe bacterial infections, such as those affecting the bloodstream or organs.
