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.

  • jennypoo - It Works does Not Work!

    Another product that is useless. I have used these several times because they were given to me by a girl who got out of the business of selling them. Like ANYTHING that you spend money on, relax with for a little while, your skin is going to feel and look rested the same as when you get a facial. It brightens your skin for a while and you think you see a difference, until the next morning...money down the drain. These things are totally too expensive..in the long run, more than a professional office can give you.

  • Courtney - Only buy if you don't plan on returning. I returned this product and only got $34.72 back in return....

    I am an interior designer and thought this would be the right product to help me in creating designs. After using Chief Architect Home Designer Pro, I found out it was not the right design software for what I needed it to do. I purchased Sketch Up Pro from another vendor and was a much better application for interior design work. In good faith, I returned Chief Architect Home Designer Pro only to find out they had a restocking fee of $495.99 of the full amount. I think this is a poor way of doing business, since I will never use the software for my work.

  • Marie Liebau - The rest is so bad I can't believe anyone would promote it

    I grave this 1 Star for the cover picture. The rest is so bad I can't believe anyone would promote it.It's so bad it's not even good enough to make fun of.
