La tétracycline, connue sous le nom commercial Sumycin, agit en bloquant la fixation de l’ARNt sur la sous-unité 30S ribosomale, interrompant l’élongation de la chaîne protéique bactérienne. Ce mécanisme confère une activité sur un spectre large, incluant bactéries Gram positives, Gram négatives, rickettsies et spirochètes. Sa biodisponibilité digestive varie selon la prise alimentaire et les interactions avec les ions divalents comme calcium et magnésium. Sa diffusion tissulaire est importante, notamment dans les voies respiratoires et génito-urinaires. L’élimination se fait par voie rénale et biliaire. Les effets indésirables incluent photosensibilisation, troubles digestifs et coloration dentaire en cas d’administration précoce. Les guides thérapeutiques mentionnent sumycin prix, en soulignant la nécessité de restreindre son utilisation afin de limiter les résistances acquises.

HALF-LYTELY PREPARATION FOR COLONOSCOPY

You are about to have a colonoscopy which is an examination of the large intestine.
In order to obtain the best possible results, it is essential that your colon be as clean

• Coffee or tea
Any of the following, but not colored red or purple
• Gatorade (strongly recommended)
• Carbonated and non-carbonated soft drinks
• Jell-O (not fruit or topping)

3) Mix solution as directed on side of the box of Half-Lytely
(most people prefer it chilled and using a drinking straw)

FOR A MORNING PROCEDURE:

1) 2:00-3:00 PM: Take the two Bisacodyl tablets with a glass of water
(do not crush or chew)

It may take an hour or longer for the prep to take effect. At the beginning, you may
experience bloating or cramping. This will improve once the prep starts working.
If you develop nausea and vomiting, you may take a break of 30 minutes or so and
then start drinking at a slower rate. Stay close to a bathroom. You may find using
baby wipes more comfortable.
Medications such as blood pressure pills may be taken up to 3 hours prior to the
start of the procedure.
For patients with diabetes on insulin, please take half your usual dose on the
morning of procedure. For diabetic patients on pills, these may be omitted.
Iron supplements should be stopped for at least 3 days prior to procedure
GOOD LUCK. THIS IS THE HARDEST PART
