Chloramphenicol is metabolized by the alarmist to chloramphenicol glucuronate (which is inactive). In alarmist impairment, the dosage of chloramphenicol have to accordingly be reduced. No accepted dosage abridgement exists for chloramphenicol in alarmist impairment, and the dosage should be adapted according to abstinent claret concentrations.
The majority of the chloramphenicol dosage is excreted by the kidneys as the abeyant metabolite, chloramphenicol glucuronate. Only a tiny atom of the chloramphenicol is excreted by the kidneys unchanged. Claret levels should be monitored in patients with renal impairment, but this is not mandatory. Chloramphenicol succinate ester (an intravenous prodrug form) is readily excreted banausic by the kidneys, added so than chloramphenicol base, and this is the above acumen why levels of chloramphenicol in the claret are abundant lower if accustomed intravenously than orally.
Chloramphenicol passes into breast milk, so should accordingly be abhorred during breast feeding, if possible.
