Pharmacological toxicology is a chloramphenicol antibiotic. Invitro, there is a wide spectrum of antimicrobial activity,including the anaerobic gram-negative bacteria and thegram-positive bacteria, anaerobic bacteria, the rickettus,spirochetes, and chlamydia. Bacteria-killing bacteria:haemophilus influenzae, streptococcus pneumoniae and

neisseria meningitidis. On the following bacteria only hasbacteriostatic action: staphylococcus aureus, suppurativehemolytic streptococcus, streptococcus viridans, group Bstreptococcus, escherichia coli, klebsiella pneumoniae,singular proteus, typhoid fever, salmonella paratyphoidsalmonella, shigella, bacteroides fragilis anaerobic bacteria,etc. The following bacteria are usually of chloramphenicolresistance: pseudomonas aeruginosa, acinetobacter, e. coli,glue Mr Charest bacteria, indole, proteus, methicillinresistant staphylococcus aureus and enterococcus. This productis a bacteriostatic agent. Chloramphenicol is fat soluble,through dispersion into the bacterial cells, and reversible inbacterial ribosome on the 50 s subunit of the peptide chainblocked (probably due to the inhibitory effect of thetranspeptidase) , thus inhibiting the formation of the peptidechain, so as to prevent the synthesis of protein.

Valid for 12 monthsstandards < < China pharmacopoeia > > 8 ml : 2005 edition ofspecifications 20 mg related news chloramphenicol eye drops:pharmacy why no longer sell recently, the state food and drugsupervision and administration department: will include 12kinds of chloramphenicol eye drops, over-the-counterpreparations to prescription. This means that consumers willnot be able to freely buy 12 over-the-counter agents, includingchloramphenicol drops (ear drops) , from the pharmacy."Aplastic anemia" - side effects cannot be ignored

Chloramphenicol is a broad-spectrum antibiotics, not only hasan effect on a variety of bacteria, but also has effect forchlamydia, etc. Chloramphenicol eye drops (including ear

drops) , the price is relatively cheap, and in the past belongsto the over-the-counter drugs, eye (ear) some discomfort, somany people don' t want to go to the hospital, the figure isconvenient, often go to the pharmacy to buy chloramphenicol eyedrops drop eye (ears) . Although a dosage of chloramphenicol eyedrops (ear drops) is much smaller than the systemic application,but don't ask, don' t cause, random drops with antibiotics eyedrops (ear drops) , also belong to the category of abuse ofantibiotics, very wrong. If are sensitive to chloramphenicol,or long-term use of chloramphenicol eye drops (ear drops) , thepatient may also produce toxic effects of the blood, the mostserious is has nothing to do with the dosage of bone marrowtoxicityreaction, whichproduce irreversible aplastic anemia.Generally speaking, this anemia can have several months ofincubation period, which is not easy to detect early, but canbe characterized by bleeding tendency, such as subcutaneousstasis, stasis, and nosebleed. In addition, because of thedecrease of granulocytes inwhite blood cells, it can also leadto infection, such as high fever, sore throat, jaundice, andpallor. So far, there is no way to predict severe reactions andside effects of drugs, such as a sensitive trial like certaindrugs. Experts suggest that the following high-risk groups arenot suitable for the use of chloramphenicol drops (ear drops) :the innate glucose-6-phosphate dehydrogenase is not sufficient;Pregnancy and lactation women, as this may endanger fetuses andnewborns; Patients are using drugs that inhibit the use of bonemarrow, such as antitumor drugs such as colchicine, butae, andpenicillium. If the function of liver function is not good, theperson who has injury to kidney function should be used oravoided. (5) the old. Anti-infection-chloramphenicol drops areno longer the "first choice", and chloramphenicol drops are

frequently used in the treatment of chloramphenicol. Now,sanitation, good trachoma has been largely destroyed, eyeitching, foreign body sensation, symptoms such as tears are notnecessarily trachoma, is likely to be other bacterialinfections. Other eye drops should be under the guidance of thedoctor.

"Check" related materialand p-hydroxy benzoic acid esters preservatives Put A properamount of this product, with the mobile phase (A - B (68, 32)quantitative dilutionmade each 1 ml contains 0.5 mg of solution,as the test solution; Another chloramphenicol diol contentreference substance and reference substance of nitrobenzeneformaldehyde, chloromycetin reference substance and methylp-hydroxybenzoate, p-hydroxy benzoic acid ethyl ester,p-hydroxy benzoic acid n-propyl, adequate precision said, addmethanol moderate dissolved, with mobile phase (A-B (68, 32)quantitative dilution into each 1 ml contains chloramphenicol

0.2 mg, chloromycetin diol content 5 mu g, for nitrobenzeneformaldehyde, methyl p-hydroxybenzoate 16 mu mu g g, p-hydroxybenzoic acid ethyl ester 20 mu g and p-hydroxy benzoic acidn-propyl eight mu g mixture, as the material and p-hydroxybenzoic acid ester preservative reference substance solution.According to content determination under the chromatographicconditions, take 10 mu l reference solution into thechromatograph, adjust the detection sensitivity, make thechloramphenicol diol content peak of peak Gao Weiman range of20%~ 25%. The precision is obtained by using the liquid phasechromatograph and recording the chromatogram. In the area of

peak area, chloramphenicol can not be used for 8.0%, andcontains no more than 0.5% of nitrobenzaldehyde. Such ascontaining the corresponding preservatives, methylp-hydroxybenzoate, p-hydroxy benzoic acid ethyl ester,p-hydroxy benzoic acid ester c should be in the prescriptionof quantity (or label) 80.0%~120.0%. Microbial limit for thisproduct, diluted with sterile sodium chloride - peptone pH7.0buffer into each 1 ml contains about 0. 1 mg of solution,according to the membrane filtration method (appendix XI H)after treatment, use the buffer wash washing amount not lessthan 500 ml/membrane, to staphylococcus aureus [26003] CMCC (B)as the positive control bacteria, inspection in accordancewiththe law, should comply with the rules. The high performanceliquid chromatography (appendix V D) was determined. Thechromatographic conditions and system applicability test werefilled with octadecyl silane bonding silicone. Mobile phase Ais 0.01 mol/L heptane sodium sulfonate solution (0.01 mol/Lheptane sulfonic acid sodium solution 1000 ml, potassiumdihydrogen phosphate 6.8 g and triethylamine 5 ml, blending,with phosphoric acid to adjust pH value to 2.5) , mobile phaseB for methanol ; The detection wavelength is 27mm m. Take therelevant matter and the 10 mu l injection chromatograph for theantiseptic of hydroxybenzoic acid, andpress the table gradient.The number of theoretical plates of chloramphenicol is not lessthan 2500, and the separation degree of adjacent peaks shouldmeet the requirements.
