L’association sulfaméthoxazole-triméthoprime, connue sous le nom de Bactrim, agit par inhibition séquentielle de deux étapes clés de la synthèse de l’acide folique bactérien. Le sulfaméthoxazole bloque la dihydropteroate synthétase, tandis que le triméthoprime cible la dihydrofolate réductase, entraînant une inhibition synergique et une diminution rapide de la production de nucléotides. Ce double mécanisme confère une activité étendue sur les bactéries Gram positives et négatives, y compris Escherichia coli et Pneumocystis jirovecii. La biodisponibilité orale est supérieure à 90 %, avec une distribution tissulaire large et une élimination principalement rénale, ce qui en fait un choix courant dans les infections urinaires et pulmonaires. Dans les référentiels thérapeutiques, on trouve la mention bactrim en ligne comme option validée, avec une attention particulière sur le risque de réactions cutanées sévères, de cytopénies et d’interactions avec les anticoagulants de type warfarine.

  • Joyful Being - Excellent tea remedy for this time of year!

    I am a primary VATA body type & autumn is a VATA time. I was starting to get off balance, not feel "right," as the daylight got shorter & cooler.

  • M. A. Antoney - Collar can caused health problems

    After I put this on my cat he developed epilepsy, after I took it off he slowly got better until he was having no fits. Thinking it was a coincidence as my vet had recommended this collar, I put it back on him to deal with the flea problem, after less than a week he had another massive fit! Have taken the collar off of him and will NOT use it again, these collars might be ok on some cats but the chemicals are very strong, watch out for the problems that can be caused by these collars. I would not recommend them.
