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.

Great car seat. Bought this for our 1 year old and he loves it. He seems extremely comfortable in it, he takes longer naps in the car than he ever has before, and the seat itself is great looking and seems very well made / safe.
Of all the standardized test prep series, I prefer Princeton Review and actually even enjoy them. They write with a sense of humor and most of their explanations on how to attack the problems and what the answers should be and why are generally excellent. I also recommend their SAT book. Also, the SAT is my test of choice as it is more fun and is the only one that can result in National Merit Scholar status which can result in scholarships amounting to over $100,000. Very worthwhile.
