BEYAZ vs VIORELE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination of ethinyl estradiol and drospirenone suppresses gonadotropins (FSH and LH) from the pituitary, inhibiting ovulation, altering cervical mucus, and inducing endometrial changes. Drospirenone is a spironolactone analogue with antimineralocorticoid and antiandrogenic activity.
VIORELE is a monoclonal antibody that binds to and inhibits the activity of interleukin-17A (IL-17A), a pro-inflammatory cytokine involved in the pathogenesis of plaque psoriasis, psoriatic arthritis, and ankylosing spondylitis.
One tablet (drospirenone 3 mg / ethinyl estradiol 0.02 mg) orally once daily for 24 days, followed by 4 days of placebo.

Drospirenone: approximately 30 hours (terminal). Ethinyl estradiol: approximately 13-15 hours (terminal). Steady-state reached within 10 days. Clinical context: once-daily dosing maintains therapeutic levels with minimal accumulation after 3-4 cycles.
Terminal elimination half-life of 12–15 hours (mean 13.5 h) in healthy adults; may be prolonged in renal impairment (up to 30 h).
Urine (45-55% as metabolites), feces (30-40% as metabolites), with enterohepatic recirculation of ethinyl estradiol metabolites.
Primarily renal (unchanged drug and metabolites, ~60%) and fecal (~30%), with minor biliary contribution (~10%).
