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.

  • LinkFan - I wouldn't use this to speed cube but it turns much better than a standard Rubik's brand 3x3

    Standard 3x3. Turns well. I wouldn't use this to speed cube but it turns much better than a standard Rubik's brand 3x3.

  • Cat Saunders, Ph.D. - Earthing rocks!

    As a longtime counselor and healthcare provider, the Earthing book opened my eyes to a source of support and healing that I had never considered before--the gift of being grounded to the Earth in the literal sense of that word.

  • james b potter - Worked wonders for me

    I began using this after a bout of severe hair loss following an illness. When my hair didn't seem to be rallying on it's own I ordered this. Within two months I had a lot of new hair and now it looks as though I have at least as much hair as before. Realistically, it won't help everyone but it certainly wouldn't hurt to give it a try.

  • eyes N ears - Works great...no problems.

    has worked great for me so far. It's found a couple of issues and fixed them quietly. No problems with slowdowns or issues with interruptions.

  • anonymous - Surprising to me...

    My hair: straight, fine, fairly thick, OILY. I have always had to wash it daily or I can't stand it. I have tried no 'poo (baking soda and apple cider vinegar) and it did ok....after a while of it my hair just wasn't quite as shiny and soft. I have tried 'low poos' like the 'Ology brand from Walgreens and the one from Garnier (forgot what it's called) and they are fine. I haven't actually used conditioner in YEARS because my hair doesn't need it and it weighs it down.
