E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the effect of a Roux-en-Y gastric bypass on the pharmacokinetics of a single oral dose of 1000 mg paracetamol before the surgery. within one month after the surgery and 6 months after the surgery. |
Beschrijven van het effect van RYGB op de farmacokinetiek van een eenmalige orale gift van 1000 mg PCM, voorafgaand aan de ingreep, binnen de eerste maand na ingreep en 6 maanden erna. |
|
E.2.2 | Secondary objectives of the trial |
To assess the effect of a Roux-en-Y gastric bypass on the pharmacokinetics of the metabolites paracetamol glucuronide (PCM-GLU), paracetamol sulfate (PCM-SUL), paracetamol mercatopurate (PCM-MER) and paracetamol cysteine (PCM-CYS) after a single oral dose of 1000 mg paracetamol before the surgery, within one month after the surgery and 6 months after the surgery.
To assess the effect of a single dose of 1000 mg paracetamol on aspartate aminotransferase (ASAT), alanine aminotransferase (ALAT), gamma-glutamyltransferase (γ-GT) and bilirubin after 6 and 24 hours of oral intake of paracetamol before and after Roux-en-Y gastric bypass |
Secundair wordt de farmacokinetiek van de metabolieten paracetamolglucuronide (PCM-GLU), paracetamolsulfaat (PCM-SUL), paracetamolmercatopuraat (PCM-MER) en paracetamolcysteïne (PCM-CYS) bestudeerd na een eenmalige orale gift van 1000 mg paracetamol.
Nagaan wat het effect is van een eenmalige gift van 1000 mg paracetamol oraal op aspartaat aminotransferase (ASAT), aminiotransferase (ALAT), gamma-glutamyltransferase (γ-GT) en bilirubine na 6 uur na inname van paracetamol voor en na RYGB. |

|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The end point is determined at maximally 2 months before Roux-en-Y gastric bypass (RYGB) and at weeks - 1 month and 5-7 months after RYGB. |
Het eindpunt wordt maximaal 2 maanden voor Roux-en-Y gastric bypass (RYGB) bepaald, en vervolgens op 2 weken - 1 maand en 5-7 maanden na RYGB. |
|
E.5.2 | Secondary end point(s) |
Secondary end point is the pharmacokinetics of the metabolites (paracetamol glucuronide, paracetmol sulfate, paracetamol mercatopurate and paracetamol cysteine) after a single oral dose of 1000 mg paracetamol before and after RYGB
Additional secondary end points are ASAT, ALAT, γ-GT and bilirubin values. |
Secundaire uitkomstmaat is de farmacokinetiek van de metabolieten (paracetamolglucuronide, -sulfaat, -mercaptopuraat, en -cysteine)
Aanvullende secundaire uitkomstmaten zijn ASAT- en ALAT, γ-GT en bilirubinewaarden. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
The pharmacokinetic profiles are determined at maximally 2 months before Roux-en-Y gastric bypass (RYGB) and at weeks - 1 month and 5-7 months after RYGB.
The liver values are determined at T=0, T=6 h and T=24 h at each of the timepoints at which a plasma-concentration curve is measured. |
De farmacokinetische profielen worden maximaal 2 maanden voor Roux-en-Y gastric bypass (RYGB) bepaald, en vervolgens op 2 weken - 1 maand en 5-7 maanden na RYGB.
