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.

I purchased the Dinair airbrush system along with extra make up. After the first use the system clogged up after just 1/2 of one side of my face. I took it apart, cleaned it all out and five minutes into the the next try it was clogged up again. I am so frustrated at this point so I decided to write Dinair for an inquiry about returning the product. I sent that request on July 7th, it is Sept. 5th and I have yet to receive a reply. I have no faith in this company so I will not waste my time trying to pursue them for satisfaction just to be neglected which would lead to total frustration. I have chalked this up to one of the most expensive failed purchases of my life! After 50 years, I can say this is the worst purchase I have ever made, with the absolute worst level of satisfaction and customer service possible. I really don't know how they stay in business. There is a star rating required to leave the feedback so I will give one star but I want to give no stars because in my opinion they never deserved a single star. I would not recommend purchasing the Dinair Airbrush System! Run away from this site and don't look back and consider yourself fortunate you were not one of us with a faulty system with nowhere to turn for assistance!
Immediately on installation of this product my system started downloading adware without my permission. Nothing I did could stop it. After downloading fifteen separate adware programs on to my system, my computer crashed. I restarted the system but was completely unable to get online - every time I tried, my browser was hijacked to an adware site trying to either sell me something or get me to download even more garbage on my system. I tried removing the unwanted programs from my system through Windows but wasn't able to remove them all. I tried contacting McAfee but they wanted $150 in order to fix my system (which they insisted couldn't have been harmed by their product).
