About

Volunteers with a prescription of oral sertraline who have been scheduled to bariatric surgery in either Norrköping/Sweden or Lindesberg/Sweden will be asked to participate in a observational study. The aim of this study is to evaluate the absorption and the effect and side effects of sertraline in volunteers 8 weeks before and 1, 6 and 12 months after bariatric surgery.

Full description

The pharmacokinetic changes of sertraline after bariatric surgery are studied by assessing the exposition for sertraline in individuals with long term treatment by measuring the area under the curve (AUC0-τ) 8 weeks before and one, six and twelve months after bariatric surgery in 30 participants.

The effect of variation of sertraline concentration is studied by a psychiatric assessment of depressive symptoms and symptoms of anxiety disorder. The aim ist to study if there is a relation between changes in pharmacokinetics and effect of sertraline after bariatric surgery.

For the assessment of side effects a self-reporting scale is used. These participants are recruited consequentially with the aim to get equal numbers of patients with both most usual types of surgery in Sweden (laparoscopic RYGB and gastric sleeve).

Enrollment: 3 patients
