NCT ID:
NCT01258504
Brief Summary:
The aim of the present study is to assess the impact of the cytochrome P450 2C9 (CYP2C9) genotype (\*2 and \*3 allele versus wild type; \~3-5% poor metabolisers in Caucasian population) on the pharmacokinetics of bosentan and the impact of CYP3A4-induction by St. John's wort (SJW) on steady state bosentan which is a CYP3A4 inducer itself.
Detailed Description:
We evaluate the effect of SJW on bosentan pharmacokinetics and its relationship to polymorphisms in the CYP2C9 gene known to reduce CYP2C9 activity. This study will be conducted at bosentan steady-state because concentrations decrease in the first 10 days of treatment due to auto-induction of the metabolism.
