Résumé

La chirurgie bariatrique, quelle que soit sa nature, peut théoriquement avoir un impact sur l’absorption des médicaments. Cela n’est pas sans conséquence sur le suivi des patients obèses qui sont le plus souvent polymédiqués et se voient prescrire, à long terme, des molécules à fenêtre thérapeutique étroite. La littérature ne rapporte que peu d’informations sur ce sujet et suggère qu’en fonction des propriétés physicochimiques des molécules, une diminution significative de l’absorption peut être observée. Cela met en avant la nécessité de mener des études pharmacocinétiques dédiées et d’intensifier le suivi thérapeutique pharmacologique chez les patients obèses bénéficiant d’une chirurgie bariatrique.

Abstract

Little is known about the effect of bariatric surgery on the absorption of drugs. However, this surgery is commonly performed and bariatric patients often have multiple long-term therapies, some of them having narrow therapeutic windows. From the published literature, we conclude that 1) there is a potential for reduced drug absorption after bariatric surgery, 2) pharmacokinetic studies are needed to explore the impact of the surgery in obese patients, and 3) to avoid therapeutic failures, a systematic therapeutic drug monitoring is recommended on a case-by-case basis.
