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.

  • Andy - This is a Masterpiece, Landmark Collection which needs to be Heard

    Amazing, important piece of work.... a masterpiece by any standard. Talk about a collection that is passionate, creative, speaks to the heart, and most important of all, the harmonies and solo vocals are impeccable. This collection will stand out as probably the best release for the year. It's a shame that they can't record anymore as a Trio, so let's all be grateful that Emmylou has unearthed the 3rd CD of outtakes, which completes this wonderful gem of a collection. Highly, highly recommended -- a must have for any music collection.

  • Angela Stutes - WASTE of MONEY!!!

    You will only get to take this medication for 5 days. There are 30 pills in this bottle. You take 2 pills 3 times a day. Therefore you would need at least 6 bottles for just one month. I feel deceived.

  • Amazon Customer - Very slow progress but worth the wait

    I have been taking it for 18 months. At first I took only two a day because they were so expensive. The next 3 month supply I took 3 a day. I'm not very good at taking pills consistently but I definitely noticed a difference. Not a huge difference but some improvement. I wish I had taken before photos. About 6 months ago I started using a very cool temp to blow dry my hair. I noticed a difference again so when I ran out of pills I stopped taking them. That was about 3 weeks ago. Now my hair is falling out as bad as it ever has.

  • E. Sieben - Works for my small biz

    I needed software to track my small business finances and this is doing the job nicely. It's intuitive to set up and has everything I need to keep track of spending, income and everything else I need. I looked at alternatives but decided to go with what seems to be the standard. I'm not disappointed.

  • Amazon Customer - Broken righty out of the bad packaging. Don't get this

    Static lines all over screen. Broken righty out of the bad packaging. Don't get this, complete waste of money and time.
