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.

  • Thomas M. Zabala - Product worth considering

    I have been using this Nioxin product for a number of years in combination with their shampoo/conditioner products and medically prescribed Propescia. As a result I have been able to retain a good head of hair at my age when my family heritage predicted male pattern baldness.

  • R Sanchez - The clarity of my SM-57 shines like the sun

    The clarity and richness of my 44.1k 16 bit CDs shine through like the sun's rays in a latrine. You can almost hear the nicotine resin on the drummer's fingertips rubbing against the maple grained sticks being so beautifully recorded through the SM-57 microphones. Absolutely brilliant and a bargain at only $8000. Don't be fooled by those cheap thousand dollar cables.

  • Milanda Phelps - All-Natural Product!

    Aging sucks! I will just start this review with that. I have noticed that my memory, while still great, is not all it used to be. I purchased these pills in the hope of helping a bit with the memory issue. In addition, the pills claim to help with learning and cognition. They do specifically state to only use if you are over 18. I am unsure why that is, maybe because they have not been FDA approved?? In any event, they are all-natural and contain a blend of alpha glycerylphosphorylcholine. Each capsule has 325 mgs and the instructions state to take one or two pills per day based on your health care provider’s instructions. I do like that they encourage you to share the pills with your provider and get his or her opinion on the number you should take. This tells me that they are unconcerned with physician’s thinking the product is unhealthy. I am not yet sure of the effectiveness of the product as I believe it will take several weeks to see the full effect. I will say that the pills do not make me nervous or nauseated at all. I will continue to take these and see if my cognition improves.
