Megestrol Acetate 0-17 nuclear receptor subfamily 1 group I member 2 Homo sapiens 68-87 34524495-5 2021 Competitive ligand binding assay was used to determine the affinity of megestrol acetate toward human pregnane x receptor (hPXR). Megestrol Acetate 71-88 nuclear receptor subfamily 1 group I member 2 Homo sapiens 102-121 34524495-5 2021 Competitive ligand binding assay was used to determine the affinity of megestrol acetate toward human pregnane x receptor (hPXR). Megestrol Acetate 71-88 nuclear receptor subfamily 1 group I member 2 Homo sapiens 123-127 34524495-11 2021 CONCLUSION: The results suggest that megestrol acetate is a specific inducer of CYP3A4 mediated by hPXR and therefore has the potential to cause drug interactions, especially in the co-administration with drugs that are substrates of CYP3A4. Megestrol Acetate 37-54 nuclear receptor subfamily 1 group I member 2 Homo sapiens 99-103
