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.

  • Mylene Perdiguerra - it would be that bad, but I need to use a beach towel ...

    These are comfy chairs, but I underestimated how hot the black gets in the sound. I thought bc it was so meshy, with air flowing through, it would be that bad, but I need to use a beach towel sometimes. Also, they're not as portable as I like. They fold up flat, but are a little heavy and awkward to carry. Wanted to throw them in the car to use at son's baseball games, but not sure it's convenient enough for that. They're more comfortable than the collapsible chairs that come in the bag though.

  • Amazon Customer - Great for traveling!

    This power bank works very well! I can recharge my phone as needed for several days; takes several hours to recharge but that's expected.

  • Jonno - Jason Fung and Jimmy Moore are legends!

    Jason Fung is a visionary ahead of the curve and Jimmy Moore is possibly the biggest legend in low carb on earth. I finished it in one day and life will never be the same. Medically sound and unbelievably simple and practical. Everyone who needs to lose weight or help others do so needs this book in their lives.
