Interaction Between Rimonabant and Cyclosporine and Tacrolimus (RIMONA-PILOT)
2014年12月2日 更新者：University of Oslo School of Pharmacy
The Effect of Rimonabant Treatment on Cardiovascular Risk Factors in Renal Transplant Recipients -- Pilot Safety Study
The major cause of premature death in renal transplant recipients is cardio-vascular disease.
In addition, obesity is becoming a major problem in this patient population.
Rimonabant does not only seem to have weight reducing properties but also weight reduction independent effects on insulin sensitivity and endothelial function, two important cardio-vascular risk factors.
Rimonabant therefore is an interesting drug for the treatment of transplanted patients.
Present data also indicate that rimonabant does not interact with essential immunosuppressive drugs (CsA and Tac) indicating that it most probably is safe to administer to this patient population.
However this needs to be investigated in a proper manner.
研究概览
详细说明
Renal transplant recipients are treated with life-long immunosuppressive therapy in order to prevent acute rejection episodes.
The calcineurin inhibitors (CsA and Tac) are the back-bones in the immunosuppressive treatment and they have a very narrow therapeutic index.
It is therefore essential to assure that new drug to be used in transplanted patients do not interact with CsA and Tac.
Even though rimonabant is metabolized via the same enzyme as CsA and Tac (CYP3A4) previous in vitro and in vivo studies with relevant probe drugs in healthy volunteers do not indicate the presence of any relevant pharmacokinetic interaction.
However, to be absolutely sure that it is safe to administer rimonabant in transplanted patients a 12-hour pharmacokinetic interaction investigation is included for 16 patients in the present pilot study (8 patients on CsA and 8 patients on Tac).
