Does Ritonavir Interact with Segesterone Acetate And Ethinyl Estradiol?
Ritonavir and Segesterone Acetate And Ethinyl Estradiol have a unknown drug interaction according to U.S. FDA drug labeling data. Human Immunodeficiency Virus (HIV)/ Hepatitis C Virus (HCV) Protease Inhibitors and Non-nucleoside Reverse Transcriptase Inhibitors : Significant decreases in systemic exposure of estrogen and/or progestin have been noted when CHCs are co-administered with some HIV protease inhibitors (eg, nelfinavir, ritonavir, darunavir/ritonavir, (fos)amprenavir/ritonavir, lopinavir/ritonavir, and tipranavir/ritonavir), some HCV protease inhibitors (eg, boceprevir and telaprevir), and some non-nucleoside reverse transcriptase inhibitors (eg, nevirapine). In contrast, significant increases in systemic exposure of estrogen and/or progestin have been noted when CHCs are co-administered with certain other HIV protease inhibitors (eg, indinavir and atazanavir/ritonavir) and with other non-nucleoside reverse transcriptase inhibitors (eg, etravirine). 7.4 Concomitant Use with HCV Combination Therapy – Liver Enzyme Elevation Do not co-administer ANNOVERA with HCV drug combinations containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir, due to potential for ALT elevations [see Contraindications (4) and Warnings and Precautions (5.3) ] . Patients taking both medications should consult their healthcare provider before starting, stopping, or changing the dosage of either drug.
