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.

  • BLang - Highly recommend!!

    This mask smells funky. But it works so well!!! My hair was beyond damaged. Past any hope of ever being shiny again but this brought it back to life. Highly recommend!!!!!

  • Elsie - works great!!

    This camera is a great buy for the money! I was looking for something simple and would cover me if pulled over by the police or in an accident. I also use this camera on the track and it works great. For the money this is an EXCELLENT value.this is a great little DVR. I got mine, put in a MicroSD card, plugged in two wires, and it just worked. Build quality is much better than I expected,
