What is Chloramphenicol?

Chloramphenicol is a broad-spectrum medicinal agent belonging to the class of Antibiotics. It is primarily utilised when other treatment options are not suitable or in cases of serious illness where targeted therapy is required. Because this compound carries significant potential for adverse effects, its application is generally reserved for life-threatening or difficult-to-treat scenarios.

What Chloramphenicol is used for

Physicians typically consider this medication for specific, severe conditions that require potent antimicrobial action. It is frequently associated with the management of Typhoid Fever, where it helps inhibit the proliferation of the causative bacteria.

How does Chloramphenicol work?

This medication acts by inhibiting protein synthesis in bacteria. By binding to a specific component of the bacterial ribosome, it prevents the organism from creating the essential proteins needed for growth and replication. This interruption stops the spread of the infection and allows the natural immune system to clear the pathogen more efficiently.

Chloramphenicol brands and forms
