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.

  • L. Lofton - CB-1 Weight Gainer

    I have always been skinny. I never weighed over 97 pounds because of my fast metabolism. I tried another product but it did not help at all but now that I am using CB-1, I am hungry more often than I was before. Before CB-1 I wore a size 0 but now I wear a size 3 and a 4. I would recommend this product to anyone. I went from 97 to 106 pounds. And I love it!!! My weight goal is 130-140 so I am going to keep taking CB-1 because it has really helped me gain weight. Just because you see bad reviews about CB-1 doesn't mean that it has to keep you from buying the product. You should give it a try for those of you who struggle with trying to gain weight. The product comes with a 30 day money back guarantee.

  • James A. Ashford - Mobil 1 Gear Oil 75W-90

    I have used this oil in numerous gear boxes requiring a 75W-90 gear oil and found it works very well. It seems to rate very high in all reviews I have read. I can't say it is the best, because I have not tried or compared many other oils, but in my opinion I believe it is one of the better oils and you won't go wrong using it.

  • Alejandra Gonzalez - Another winner from Skinnytaste's Gina Homolka!

    Another winner from Skinnytaste's Gina Homolka! Her recipes are delicious, easy to prepare and nutritious. What else could you want from a cookbook? I can already tell this is going to be my "go-to" cookbook, just like her first cookbook!

  • Amazon Customer - ... his office so I think it's one of the best as you get to exercise upper & lower extremities ...

    It's what the doctor uses in his office so I think it's one of the best as you get to exercise upper & lower extremities at the same time.

  • emily - I really liked this product

    I really liked this product, it seemed to work pretty well, my only complaint would be that you have to go over the rougher spots quite a few times and i would suggest not pressing down to firm or else it will bogg down, all in all it was a pretty good product, it came with batteries, I was kind of confused on how to open it for the battery compartment though.

  • Bearshark - Backspace. Meh.

    I've been using this keyboard for a while now. It's my daily. I am unable to use the "Backspace" key. This really does make using my favorite keyboard frustrating and extremely aggravating to the point where a normal membrane would work so much better.
