PIRMELLA 7/7/7 vs YASMIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Pirmelevir is a selective inhibitor of the hepatitis C virus (HCV) NS5A protein, essential for viral replication and assembly. It disrupts the double-membrane vesicles where HCV RNA replication occurs.
Combination of ethinyl estradiol and drospirenone suppresses gonadotropins, inhibiting ovulation. Drospirenone has antimineralocorticoid activity, reducing water retention, and antiandrogenic activity.
PIRMELLA 7/7/7 is a combination oral contraceptive containing ethinyl estradiol 0.035 mg and norgestimate 0.180/0.215/0.250 mg in a triphasic regimen. One tablet daily for 28 days, with 7 inactive tablets.
One tablet (ethinyl estradiol 0.03 mg / drospirenone 3 mg) orally once daily for 21 days, followed by 7 days of placebo.

Terminal elimination half-life: 8-10 hours. Clinically, steady-state reached in 2-3 days.
Terminal elimination half-life is approximately 30 hours for drospirenone; steady-state concentration is achieved after 10 days of daily dosing.
Renal: 70% unchanged; fecal: 30% as metabolites.
Approximately 40% renal and 60% fecal after oral administration; metabolites are excreted as glucuronide and sulfate conjugates.
