PIRMELLA 7/7/7 vs QUARTETTE
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 oral contraceptive containing drospirenone, ethinyl estradiol, levomefolate calcium, and metformin. Drospirenone is a progestin with antimineralocorticoid and antiandrogenic activity. Ethinyl estradiol is an estrogen. Levomefolate calcium is a folate supplement. Metformin is a biguanide that decreases hepatic glucose production and improves insulin sensitivity.
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.
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 12-14 hours; clinically this supports once-daily dosing with steady state achieved within 2-3 days.
Renal: 70% unchanged; fecal: 30% as metabolites.
Renal excretion accounts for 55% (primarily as unchanged drug), biliary/fecal excretion 35%, and the remainder undergoes metabolic clearance.
