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.

  • Secret Squirrel - Are they truly "sublingual"?

    I ordered these to help boost my energy levels. I ordered this specific item because: the form of B-12 in this item is better absorbed, so the research seems to indicate, than over varieties. I also liked the high dosage. (As of the time of this review, there is no evidence that I have been able to find that indicates any harm in taking higher doses... some evidence suggests, and I am inclined to believe, that many could benefit from taking higher amounts of B-12...)

  • Mike Audas - I hate to say this about an American company but the ...

    I hate to say this about an American company but the floor mats did not fit very good at all. I had a set for my 2006 BMW X5 and they were awesome but something has changed. I would not suggest these for at least a 2014 Dodge Ram 1500 Sport Crew Cab. Flimsy, move all over the place in the rear and will cause a tripping hazard if not paying attention. The front set fit OK but are not as heavy duty as my original set for the Bimmer.

  • Jeffrey T - Essential tool for a variety of fixes.

    I've had many of these little bottles of Gorilla Glue, if I could remember where I put them, I would not need to buy them so often, but they work like a charm. We had a chair that needed a repair, because the wooden frame underneath was cracking, and the arm rest was pushed out of the normal position. I tried to screw it together, but the frame of the chair did not have enough wood material, and I was lacking the 'chair repair' skills that were likely needed for such a job. Enter Gorilla Glue.

  • LesL - Great Food , but expensive

    We always feed our dogs Zignature due to allergies with great results. Usually the lamb formula but more recently the kangaroo formula ..... They love the taste of the kangaroo. Too bad Amazon has decided to jack the price way up on this formula. A lot cheaper on chewy.com
