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.

  • Kerry T. Givens - Tragically addictive

    This is my sixth or seventh Haribo bulk item purchased at Amazon, and so far, perhaps my favorite. The peaches and the cherry gummies would be a close second. I would hardly call the flavor anything like actual raspberries, but like most Haribo confections, it's still very fragrant and pleasant---not at all chemical/noxious/phony. The main problem with these raspberries is their small size and interesting chewy/crunchy texture tempts you to come back for more. Before you know it, you've finished the bag, ordered three more, and are seeing an endocrinologist regularly for acute pancreatic failure---basically the highest compliment you can pay to a confectionery company. Way to go, Haribo!

  • Vickylynn322 - Better than proactive

    It's identical to proactive minus the refining mask. This product actually was better than pro active because it wasn't as drying to my skin and I have combination skin.

  • E. B. - I wear this all the time and I get plenty ...

    I wear this all the time and I get plenty of compliments! Smells real fresh, without being too overpowering. Reasonably priced too.

  • Wolfgang Gunther - Pleasant read

    Aside from the somewhat unoriginal title (too many similar listings on Amazon), this is a very pleasant thriller to read. I finished it on Kindle/iPad in essentially one pass. No point giving away the plot.
