简要总结
The main objective was to investigate the effect of concurrent dosing of 10 mg ramipril and 80 mg telmisartan on the multiple-dose pharmacokinetics of telmisartan and ramipril. Therefore the relative bioavailability of telmisartan and ramipril given in combination was determined in comparison with either telmisartan or ramipril given alone.
