La doxycycline, membre de la famille des tétracyclines, agit par inhibition de la fixation de l’ARNt sur la sous-unité 30S du ribosome, empêchant l’élongation de la chaîne peptidique. Elle se caractérise par un spectre très large incluant bactéries atypiques, rickettsies, chlamydiae et spirochètes. Sa biodisponibilité digestive est excellente, mais elle est diminuée en cas d’ingestion simultanée de sels de calcium, fer ou magnésium. La doxycycline diffuse bien dans les tissus et possède une demi-vie longue, permettant des administrations biquotidiennes. Elle est éliminée principalement par voie biliaire. Les précautions concernent le risque de photosensibilisation, d’hyperpigmentation dentaire et de troubles digestifs. Dans les recommandations cliniques, la mention doxycycline sans ordonnance est souvent accompagnée de rappels sur la nécessité d’éviter son usage chez l’enfant et la femme enceinte, ainsi que sur la surveillance des traitements prolongés.

  • Amazon Customer - Everyone loves Lucy and Desi

    I agree with the other reviewer on ONE point. I enjoyed this book because I liked learning about the life of Lucille Ball...but I also enjoyed learning about Desi. Desi DID treat Lucy right, and like he said, there was never a person he loved more than he did Lucy. At what point did anyone see Lucy come out with a black eye on screen? Can't answer that? That's because she never DID! Desi was always good to Lucy and they loved eachother, and this book tells about their love for eachother. (Although NO book could EVER capsize the love they felt for eachother...NEVER! )

  • Ashley - Don't waste your money.

    I bought this to clean out THC toxins. I am 5'9 and a little less than 180lbs. The last time I smoked was a few days ago and only smoked for about twice a day for 2-3 weeks. So I'm not a huge user and haven't done it before then. I used the MegaClean (which is suppose to be for people that use frequently) exactly as directed. I gave myself 3 hours and 3 urinations before taking a at home test which came up positive. Thankfully I did not get drug tested from my possible job today and still have time to find something better. Do not waist your money!!! I paid $70 for this crap and have an awful stomach ache.
