Study to Evaluate the Pharmacokinetics of Vitamin D (Cholecalciferol) in Patients Undergoing Obesity Surgery in a Deficit Situation and After Standardization
NCT01637155 · Status: UNKNOWN · Phase: PHASE2 · Type: INTERVENTIONAL · Enrollment: 44
Last updated 2012-07-11
Summary
Set the pattern of vitamin D supplementation in obese patients undergoing bariatric surgery in deficit of vitamin D.
Patients receive a single oral dose of vitamin D, during the 28 days will be done a kinetic curve. Then and over the next 3 months, levels are normalized. Once normalized, will be administered another single oral dose to a second pharmacokinetic evaluation.
Conditions
- Obesity
- Gastric Bypass
- Gastrectomy
Interventions
- DRUG
-
Cholecalciferol
One baseline oral dose of 50.000 UI to determine pharmacokinetics. After 28 days, patients take a period of 90 days of standardization of cholecalciferol based on baseline levels. After this period, patients receive a second oral dose of 50.000 UI to determine a second pharmacokinetics.
