What is the primary route of administration for Chloramphenicol?

Chloramphenicol is primarily administered intravenously to ensure rapid therapeutic levels of the drug in the bloodstream, particularly in serious infections such as those caused by susceptible strains of bacteria. The intravenous route allows for controlled dosing and immediate access to the systemic circulation, which is crucial for treating severe conditions where delayed response or inadequate drug levels could lead to treatment failure.

While Chloramphenicol can be given orally and can be used topically in specific circumstances, these routes are not considered the primary method for administration, particularly for severe systemic infections. Intramuscular administration is also viable, but intravenous delivery provides more immediate and effective results in critical situations. Therefore, the intravenous route is the preferred method when optimal efficacy is necessary.
