Sintesi
Coadministration of ethinyl estradiol-containing products with this HCV regimen has produced marked ALT elevations in clinical trials. The risk of liver injury makes the combination unsuitable. Drospirenone also carries a hyperkalemia concern with strong CYP3A inhibitors such as ritonavir.
Cosa significa questa interazione in parole semplici
Ethinyl estradiol-drospirenone and Ombitasvir / paritaprevir / ritonavir and dasabuvir are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Perché avviene
The mechanism of the ALT elevation is not established; ritonavir also inhibits CYP3A4 and may raise drospirenone exposure.
Cosa fare
Avoid ethinyl estradiol-containing contraceptives before and during this regimen. Switch to a progestin-only or non-hormonal method and restart estrogen only after the regimen has been completed, as advised in the labeling.
