Function  :

Chloramphenicol is effective against a wide variety of Gram-positive and Gram-negative bacteria, including most anaerobic organisms. Due to resistance and safety concerns, it is no longer a first-line agent for any indication in developed nations, although it is sometimes used topically for eye infections; nevertheless, the global problem of advancing bacterial resistance to newer drugs has led to renewed interest in its use. In low-income countries, chloramphenicol is still widely used because it is exceedingly inexpensive and readily available

(1)Chloramphenicol is used for the treatment of serious infections when the microorganism is resistant to less toxic antibiotics and also when its ability to penetrate to the site of the infection is superior to less toxic alternative antibiotics.
Chloramphenicol is used only when safer drugs are contraindicated; pregnancy,lactation,or known hypersensitivity to this drug also prohibits its use.

(2) apply the product standard and neomycin, respectively made each 1 ml contains 20 mg of water solution.According to thin layer chromatography (TLC) test, 1 mu l learned these two solution, each point in the same silica gel H thin layer plate (silica gel h1.5o g 6 ml with 0.25% sodium carboxymethyl cellulose solution mixing plate), acetic acid - 8.8% ammonium acetate solution (corresponding: 10:40:) as developing agent, unfolds, dry, dry in 110 ºC for 20 minutes, by hot spraying with 10%  solution, the thin layer plate on ventilation, cooling, a spray starch potassium iodide solution (0.5% starch solution contained 0.5 g of potassium iodide in the 100 ml), immediately.Show the main spots by color of test sample solution and location should be the same as the main mark of the standard solution.
