Observational Study.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT03532477). This is a study registration, not published results. Lead sponsor: Norwegian University of Science and Technology. Recruitment status: RECRUITING. Study type: OBSERVATIONAL. Enrollment: 12 participants (ESTIMATED). Conditions: Obesity, Morbid. Interventions: DRUG: Venlafaxine. Primary outcome measures: Venlafaxine concentration in blood serum (area under curve (AUC)) , From baseline to 1 year postoperatively. Brief summary: Changes to gastric pH, gastric emptying time, gastrointestinal transit-time or the pre-systemic metabolizing effect of enzymes secreted in the mucosa may all alter the pharmacokinetics of medicines. These factors are potentially influenced by bariatric surgery. Little is so far known about how gastric bypass and sleeve gastrectomy impacts the biological availability of medication. In this study the pharmacokinetic effects of bariatric surgery on venlafaxine are investigated.
