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.

  • donald taylor - The type is small.

    I use my Kindle because I'm hard of seeing. Most type I can enlarge. I've always loved Popular Science but I can't make the type larger so I can't read it.

  • Michelle from Ohio - PERFECT table chair

    we bought this table chair because it seemed fairly small and easy to fold up. It is light, easy to carry, and small. It has fit at every restaurant we have tried to take it to, and also fits on our kitchen counter/breakfast bar. Very durable, easy to clean, and comfortable. It doesn't have bulky poles sticking out like all of my friend's portable chairs. They all ask me where I got this chair. My son is 7 months, and about 21 lbs already, fits him perfectly. The other thing I love that this chair has that most don't, is there is a little seatbelt inside that holds him in the center of the chair if you would like to use it. My friend's chicco chair doesn't have this and he slides all around in that one. OVERALL PERFECT CHAIR.
