Chloramphenicol<br />

• Binds to 50S bacterial-ribosomal subunits and inhibits bacterial growth<br />

by inhibiting protein synthesis.<br />

• The recommended dosage is 50 - 75 mg per kg per day for 14 days<br />

divided into four doses per day, or for at least five to seven days after<br />

defervescence.<br />

• Oral administration gives slightly greater bio availability than<br />

intramuscular (i.m.) or intravenous (i.v.) administration of the succinate<br />

salt.<br />

• The disadvantages of using chloramphenicol include a relatively high<br />

rate of relapse (57%), long treatment courses (14 days) and the frequent<br />

development of a carrier state in adults.
