🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionNot established from the available information for topical use. Systemic absorption may occur through broken skin.
DistributionNot established from the available information for topical use. When absorbed systemically, chloramphenicol distributes widely into body tissues and fluids, including cerebrospinal fluid.
Protein BindingNot established from the available information for topical use. Systemically, it is about 50-60% bound to plasma proteins.
MetabolismNot established from the available information for topical use. Systemically, chloramphenicol is metabolized in the liver, primarily by glucuronidation.
Half-LifeNot established from the available information for topical use. Systemically, the half-life is about 1.5 to 3.5 hours in adults with normal liver function.
ExcretionNot established from the available information for topical use. Systemically, it is excreted mainly in urine as metabolites and unchanged drug.
BioavailabilityNot established from the available information for topical use.
Onset of ActionNot established from the available information.
Peak Plasma TimeNot established from the available information.
Duration of ActionNot established from the available information.

How It Works

Chloramphenicol works by inhibiting bacterial protein synthesis. It binds to the 50S ribosomal subunit and blocks the peptidyl transferase activity, preventing the formation of peptide bonds between amino acids. This stops the growth and multiplication of bacteria, allowing the body's immune system to eliminate the infection.

Mechanism Steps

1
Penetration into bacterial cell: Chloramphenicol diffuses through the bacterial cell wall and membrane into the cytoplasm.
2
Binding to ribosome: It binds reversibly to the 50S subunit of the bacterial ribosome.
3
Inhibition of protein synthesis: This binding prevents the peptidyl transferase enzyme from forming peptide bonds, halting protein synthesis.
4
Bacterial growth arrest: Without protein synthesis, bacteria cannot grow or multiply, leading to their eventual death by the host's immune defenses.
