Chloramphenicol is a broad-spectrum antibiotic originally isolated from Streptomyces venezuelae. It is primarily bacteriostatic and acts by inhibition of protein synthesis by interfering with the transfer of activated amino acids from soluble RNA to ribosomes. Development of resistance to chloramphenicol can be regarded as minimal for staphylococci and many other species of bacteria.
Chloramphenicol should be used only in those serious infections for which less potentially dangerous drugs are ineffective or contraindicated. Bacteriological studies should be performed to determine the causative organisms and their sensitivity to chloramphenicol (See Box Warning). For treatment of ocular infections involving the conjunctiva and/or cornea caused by chloramphenicol-susceptible organisms.
Chloramphenicol has a wide spectrum of antimicrobial activity and is effective against many gram negative and gram positive bacteria, including the following common eye pathogens:
Streptococci, including Streptococcus pneumoniae
Moraxella lacunata (Morax-Axenfeld bacillus)
The product does not provide adequate coverage against:
This product is contraindicated in those persons who have shown hypersensitivity to any of its components.
SEE BOX WARNING.
Ophthalmic ointment may retard corneal wound healing.
Prolonged use of antibiotics may occasionally result in overgrowth of non-susceptible organisms, including fungi. If new infections appear during treatment, the therapy should be altered. In all serious infections, the topical use of chloramphenicol should be supplemented by appropriate systemic medication.
Blood dyscrasias may be associated with the systemic use of chloramphenicol. One case of bone-marrow hypoplasia following the prolonged (23 month) topical use of chloramphenicol ophthalmic solution has been reported.
