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 - Great replacement for the OEM plastic cap

    Great replacement for the OEM plastic cap. Fits snug and the magnet works great to keep the fuel cap close and secure while fueling.

  • Kindle Customer - An exceptionally well composed GRE testing resource

    I am amazed at how well designed and delivered this book, and even more importantly the online component of the course was set-up.

  • Kristen - Works great out of the box

    Works great out of the box. I had no problem getting the machine set up and running. I was a little worried about purchasing because there are a lot of reviews about the issues with the firmware update and such. I thought the instructions for the firmware update was pretty self explanatory. The only issue I did have was that I had was because I just updated my Mac and the firmware wasn't recognizing the computer, so I had to run the firmware update through the PC. Other than that it was smooth sailing.

  • S. Shallcross - Terrible

    Terrible set up process - I would describe the set up process as the exact opposite of plug-and-play.

  • dalepres - Has some great features, but...

    I bought this for my wife but she's not thrilled with it. It's a little heavy - perhaps twice the weight or more of the Voyager 520s she has used for years. It doesn't have the in-the-ear fitting, it's more up-to-the-ear. I think that will just take some getting used to.
