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.

    Had a 'hot spot" by computer desk, sprayed there and really took care of them. I was concerned that it was just something sold to get your money, but that doesn't seem to be the case here.

  • C Malone - If you work through this book, you will succeed

    I am way too old to be taking the GRE, and it's been over 13 years since my last standardized test. I ordered this book two months before the test, sat down and did everything it said, and totally aced the exam. They really know what they are doing at Kaplan. The guidance in this book (how to prepare for and structure the essays, what math equations to memorize, what flashcards to make) was top-notch, and the practice exams, both in the book and online, were great preparation.
