摘要: Despite its established inter-individual variability, sildenafil has been the subject of only a few pharmacogenetic investigations, with limited data regarding genetic modulators pharmacokinetics. We conducted sub-study patients randomized to (n=85) in RELAX trial, which investigated impact high-dose heart failure preserved left ventricular ejection fraction (HFpEF). In overall population, CYP3A4 inferred phenotype appeared associated dose-adjusted peak concentrations at week 12 and 24 (adjusted P=0.045 for repeated measures analysis), although this P-value did not meet our corrected significance threshold 0.0167. more homogeneous Caucasian subgroup, association was significant P=0.0165 measures). Hence, is HFpEF receiving high doses sildenafil. The clinical requires further investigation.
