Does Segesterone Acetate And Ethinyl Estradiol Interact with Ritonavir?

Segesterone Acetate And Ethinyl Estradiol and Ritonavir 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. This information is based on official FDA drug labeling sourced from OpenFDA and the NIH National Library of Medicine.
