Tetracyclines

Tetracyclines are a group of broad-spectrum antibiotics that are used to treat a variety of bacterial infections. They are effective against both Gram-positive and Gram-negative bacteria, making them a versatile treatment option for many different types of infections.

Mechanism of Action

Tetracyclines work by inhibiting protein synthesis in bacteria. They bind to the bacterial ribosome, preventing the attachment of aminoacyl tRNA to the mRNA-ribosome complex. This ultimately leads to the inhibition of protein synthesis in the bacteria, which impairs their ability to grow and multiply.

Common Uses

Tetracyclines are commonly used to treat infections such as acne, urinary tract infections, respiratory infections, and certain sexually transmitted infections. They are also used in the treatment of Lyme disease, cholera, and anthrax.

Side Effects

Some common side effects of tetracyclines include gastrointestinal upset, photosensitivity, and discoloration of teeth in children. It's important to use sunscreen and avoid prolonged exposure to sunlight while taking tetracyclines to minimize the risk of photosensitivity reactions.
