Chloramphenicol is a broad-spectrum antibiotic that inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit. It was once widely used to treat serious bacterial infections such as typhoid fever, meningitis, and eye infections, but is now rarely used systemically due to its risk of serious adverse effects such as aplastic anemia. Topical (ocular) formulations are still approved and used for eye infections.
