Derm Chloramphenicol 500
Derm Chloramphenicol 500 Uses, Dosage, Side Effects, Food Interaction and all others data.
Derm Chloramphenicol 500 inhibits bacterial protein synthesis by binding to 50s subunit of the bacterial ribosome, thus preventing peptide bond formation by peptidyl transferase. It has both bacteriostatic and bactericidal action against H. influenzae, N. meningitidis and S. pneumoniae.
Derm Chloramphenicol 500 is a broad-spectrum antibiotic that was derived from the bacterium Streptomyces venezuelae and is now produced synthetically. Derm Chloramphenicol 500 is effective against a wide variety of microorganisms, but due to serious side-effects (e.g., damage to the bone marrow, including aplastic anemia) in humans, it is usually reserved for the treatment of serious and life-threatening infections (e.g., typhoid fever). Derm Chloramphenicol 500 is bacteriostatic but may be bactericidal in high concentrations or when used against highly susceptible organisms. Derm Chloramphenicol 500 stops bacterial growth by binding to the bacterial ribosome (blocking peptidyl transferase) and inhibiting protein synthesis.

Uses
Derm Chloramphenicol 500 is used for Ocular infections, Bacterial meningitis, Anaerobic bacterial infections, Anthrax, Brain abscess, Ehrlichiosis, Gas gangrene, Granuloma inguinale, Infections caused by H. influenzae, Listeriosis, Plague, Psittacosis, Q fever, Severe gastroenteritis, Severe melioidosis, Severe systemic infections with Camphylobacter fetus, Tularaemia, Whipple's disease, Otitis externa
Derm Chloramphenicol 500 is also used to associated treatment for these conditions: Acne, Bacterial Conjunctivitis, Bacterial Conjunctivitis caused by susceptible bacteria, Bacterial Infections, Bacterial dacryocystitis, Bacterial diarrhoea, Conjunctivitis allergic, Corneal Inflammation, Eye swelling, Keratitis bacterial, Ocular Inflammation, Trachoma, Anterior eye segment inflammation, Bacterial blepharitis, Bacterial corneal ulcers, Non-purulent ophthalmic infections caused by susceptible bacteria, Superficial ocular infections, Skin disinfection
How Derm Chloramphenicol 500 works
Derm Chloramphenicol 500 is lipid-soluble, allowing it to diffuse through the bacterial cell membrane. It then reversibly binds to the L16 protein of the 50S subunit of bacterial ribosomes, where transfer of amino acids to growing peptide chains is prevented (perhaps by suppression of peptidyl transferase activity), thus inhibiting peptide bond formation and subsequent protein synthesis.
Dosage
Derm Chloramphenicol 500 dosage
For Eye: Adults, children and infants (all age groups): One or two drops 4 to 6 times a day should be placed in the infected eyes. If necessary the frequency of dose can be increased. Treatment should be continued for approximately 7 days but should not be continued for more than three weeks without re-evaluation by the prescribing physician.

Otic/Aural: Otitis externa:Instill 2-3 drops of a 5% solution into the ear bid-tid.
Oral:Bacterial meningitis, Anaerobic bacterial infections, Anthrax, Brain abscess, Ehrlichiosis, Gas gangrene, Granuloma inguinale, Infections caused by H. influenzae, Listeriosis, Plague, Psittacosis, Q fever, Severe gastroenteritis, Severe melioidosis, Severe systemic infections with Camphylobacter fetus, Tularaemia, Whipple's disease:
- Adult:50 mg/kg/day in 4 divided doses increased to 100 mg/kg/day for meningitis or severe infections due to moderately resistant organisms. Continue treatment after the patient's temperature has normalised for a further 4 days in rickettsial disease and 8-10 days in typhoid fever.
- Child:Premature and full-term neonates: 25 mg/kg/day in 4 divided doses. Full-term infants >2 wk: 50 mg/kg/day in 4 divided doses. Children: 50 mg/kg/day in 4 divided doses increased to 100 mg/kg/day for meningitis or severe infections.

Oral: GI symptoms; bleeding; peripheral and optic neuritis, visual impairment, blindness; encephalopathy, confusion, delirium, mental depression, headache. Haemolysis in patients with G6PD deficiency.
ophthalmic application: Hypersensitivity reactions including rashes, fever and angioedema.
Ear drops: Ototoxicity.
Toxicity
Oral, mouse: LD50 = 1500 mg/kg; Oral, rat: LD50 = 2500 mg/kg. Toxic reactions including fatalities have occurred in the premature and newborn; the signs and symptoms associated with these reactions have been referred to as the gray syndrome. Symptoms include (in order of appearance) abdominal distension with or without emesis, progressive pallid cyanosis, vasomotor collapse frequently accompanied by irregular respiration, and death within a few hours of onset of these symptoms.
Precaution
Impaired renal or hepatic function; premature and full-term neonates. Monitor plasma concentrations to avoid toxicity.
Interaction
Decreased effects of iron and vitamin B12 in anaemic patients. Phenobarbitone and rifampin reduce efficacy of chloramphenicol. Impairs the action of oral contraceptives.

Elimination Route
Rapidly and completely absorbed from gastrointestinal tract following oral administration (bioavailability 80%). Well absorbed following intramuscular administration (bioavailability 70%). Intraocular and some systemic absorption also occurs after topical application to the eye.
Half Life
Half-life in adults with normal hepatic and renal function is 1.5 - 3.5 hours. In patients with impaired renal function half-life is 3 - 4 hours. In patients with severely impaired hepatic function half-life is 4.6 - 11.6 hours. Half-life in children 1 month to 16 years old is 3 - 6.5 hours, while half-life in infants 1 to 2 days old is 24 hours or longer and is highly variable, especially in low birth-weight infants.

Pregnancy Category C. Either studies in animals have revealed adverse effects on the fetus (teratogenic or embryocidal or other) and there are no controlled studies in women or studies in women and animals are not available. Drugs should be given only if the potential benefit justifies the potential risk to the fetus.
