Atripla<Superscript>R</Superscript>/anti-TB combination in TB/HIV patients. Drug in focus

Background

Co-administration of anti-tuberculosis and antiretroviral therapy is often inevitable in high-burden countries where tuberculosis is the most common opportunistic infection associated with HIV/AIDS. Concurrent use of rifampicin and several antiretroviral drugs is complicated by pharmacokinetic drug-drug interaction.

Method

Pubmed and Google search following the key words tuberculosis, HIV, emtricitabine, tenofovir efavirenz, interaction were used to find relevant information on each drug of the fixed dose combination Atripla^R

Results

Information on generic name, trade name, pharmacokinetic parameter, metabolism and the pharmacokinetic interaction with Anti-TB drugs of emtricitabine, tenofovir, and efavirenz was obtained.

Conclusion

Fixed dose combination of emtricitabine/tenofovir/efavirenz (ATRIPLA^R) which has been approved by Food and Drug Administration shows promising results as far as safety and efficacy is concerned in TB/HIV co-infection patients, hence can be considered effective and safe antiretroviral drug in TB/HIV management for adult and children above 3 years of age.

     

尾巨桉化学成分的研究

运用多种色谱手段分离纯化尾巨桉的化学成分,并通过波谱法对分离到的化合物进行结构鉴定。结果表明：从尾巨桉叶和根中分离并鉴定了5个化合物,分别为鞣花酸(ellagic acid,1)、3-O-甲基并没食子酸(3-O-methylellagic acid,2)、3,3′-O-二甲基鞣花酸(3,3′-di-O-methylellagic acid,3)、3-O-甲基鞣花酸4′-O-α-L-吡喃鼠李糖苷(3-O-methylellagic acid 4′-O-α-L-rhamnopyranoside,4)、反式对羟基肉桂酸((E )-p-hydroxy-cinnamic acid,5)。其中,化合物2~5为首次从该植物中分离得到。     

Chemical constituents from Anthemis wiedemanniana Fisch. & Mey.

The lipophilic extract of the aerial parts of Anthemis wiedemanniana Fisch. & Mey, a Turkish endemic species, was investigated. In addition to one new natural product, namely 3,4,4-trimethyl-6-carboxy-cyclohex-2-ene-1-one, five known sesquiterpene lactones, five methylated flavonoids, one simple phenolic derivative and one nor-isoprenoid were isolated. Among the sesquiterpene lactones, canin was found to be the main compound.     

Les premiers Anguilliformes : I. Révision des genres cénomaniens Anguillavus HAY, 1903 et Luenchelys nov. gen.

New specimens from Cenomanian outcrops of Lebanon permit redescribtion of the first eel-like fossil fishes. Anguillavus bathshebaeHay, 1903 becomes synonymous with the type species A. quadripinnisHay, 1903. A new fossil eel with pelvic fins, Anguillavus mazeni nov. sp., is furthermore proposed. In the same way, the revision of Luenchelys minimus nov. gen., nov. sp., reveals some morphological variations at the specific level and a widespread biogeographical repartition which potentially can be important. This whole anatomical revision is a necessary basis for integrating these fossils into the Anguilliformes (Teleostei, Elopomorpha) and gives an idea of the plesiomorphic structural pattern of the order, in which the modern forms are particularly specialised.
