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.

  • RichZ - Don't Buy It

    The software is ok but what they don't tell you is that in order to run it, you have to buy a maintenance agreement at the end of the year, which costs more than the original software - and then every other year after! When you call with questions, as part of the maintenance agreement, you are sometimes put on hold for hours.

  • That Guy - The user interface is clean and easy to figure out

    Crisp display. Colors are true and are deep. The user interface is clean and easy to figure out. The smart remote although it takes a little time getting use to the lack of a 0-9 keypad works quite well.
