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.

  • Brian M. Edwards - Reliable, With a Few Bugs

    I reviewed a previous version for the Vine program a few years ago and liked it so much I have been using it ever since. It is reliable in the sense that it seems to catch all viruses etc but is a little buggy. I installed it on my new Lenovo WIndows 8 laptop and it would not stay on autopilot mode ( basically a hands free mode where it looks after your laptop and does its own updates and maintenance without me having to do anything) however on their website, it recommended uninstalling and reinstalling the latest (kit) version which I did and it solved all my problems. If you do this, when you uninstall the old version, choose the option that tells Bitdefender you plan to reinstall the same or newer version, it will remember your serial number so you don't have to re-enter it!
