DROSPIRENONE TAB
Clinical Criteria Summary
Document 283: MON Drosperinone SLYND Mar2022
Indication(s)
- Prevention of pregnancy in females of reproductive potential
- Progestin-only contraceptive pill (POP)
Contraindications
- Renal impairment
- Adrenal insufficiency
- Liver tumors (benign or malignant) or hepatic impairment
- Presence or history of cervical cancer or progestin-sensitive cancers
- Undiagnosed abnormal uterine bleeding
- Conditions predisposing to hyperkalemia
Warnings & Precautions
- Hyperkalemia: Monitor serum potassium in patients receiving concomitant daily/chronic medications that increase potassium, strong CYP3A4 inhibitors, or who develop conditions increasing hyperkalemia risk
- Thromboembolic disorders: Consider increased risk in postpartum period and history of thromboembolism; consider discontinuation during prolonged immobilization due to surgery or illness
- Bone loss: Unclear if causes clinically significant bone loss; FDA requires post-marketing study
- Uterine bleeding irregularities/amenorrhea: Evaluate for pregnancy or malignancy if bleeding persists or occurs after previously regular cycles; consider pregnancy if scheduled bleeding does not occur
- Liver disease: Discontinue if jaundice or symptoms of liver function disturbances develop
- Risk of hyperglycemia in patients with diabetes
- Ectopic pregnancy
- Cervical cancer
- Depression
Dosing & Administration
- 24 active tablets followed by 4 inert tablets daily (24-day on, 4-day off regimen)
- Take one tablet daily at about the same time each day to maintain a 24-hour interval
- 24-hour pill forgiveness for missed or late doses
- If more than one tablet is missed, use backup contraception for 7 days
Patient Selection & Clinical Context
- Desirable for breastfeeding women and those with contraindications or desire to avoid estrogen-containing products (e.g., history of venous thromboembolism, migraine with aura, smokers >35 years)
- May be considered in patients desiring a daily POP but unable to use or intolerant of norethindrone POP
- Patient examples include: tolerance issues on norethindrone (unscheduled bleeding/spotting); contraindication to estrogen with poor candidacy for progestin shot/implant/IUD or history of failure/intolerance to norethindrone; indication for ovulation suppression (e.g., recurrent ovarian cysts) with contraindications/intolerance to other options; difficulties adhering to the 3-hour window for norethindrone despite reasonable efforts
Efficacy Considerations
- Prevents pregnancy primarily by suppressing ovulation
- Pearl Index: 4.0 (95% CI: 2.3–6.4) pregnancies per 100 woman-years in non-breastfeeding women ≤35 years
- Subgroup analyses of higher BMI did not suggest greater pregnancy risk
- Effectiveness may be less than combination products with real-world use due to strict dosing schedule, though DRSP POP offers a 24-hour forgiveness window
Safety & Adverse Reactions
- Most common adverse reactions (≥1%): Acne, metrorrhagia, headache, breast pain, weight increased, dysmenorrhea, nausea, vaginal hemorrhage, libido decreased, breast tenderness, menstruation irregular
- Discontinuations due to adverse events: 11% in pooled data; most frequent: acne, metrorrhagia, irregular menstruation, increased weight, vaginal hemorrhage, decreased libido
- Hyperkalemia: Most common serious adverse event (0.2%); typically isolated, mild, and returns to normal despite continued treatment
- Unscheduled bleeding/spotting: Decreased over time but reported in 40% of patients in cycle 13; amenorrhea reported by nearly three-quarters by end of study
Drug Interactions
- CYP3A4 inducers (e.g., phenytoin, carbamazepine, barbiturates) may decrease DRSP concentrations, potentially reducing contraceptive effectiveness and increasing breakthrough bleeding
- CYP3A4 inhibitors (e.g., ketoconazole) may increase DRSP systemic exposure
- Caution with drugs that increase serum potassium (ACE inhibitors, angiotensin-II receptor antagonists, potassium-sparing diuretics, potassium supplements, heparin, aldosterone antagonists, NSAIDs)
Special Populations
- Pregnancy: Discontinue if pregnancy occurs; epidemiologic studies/meta-analysis show no increased risk of birth defects from early inadvertent use
- Lactation: Negligible amounts excreted in breast milk; no adverse effects on milk production or infant health/development found
- Renal impairment: Mild (CrCL 50-80 ml/min) has comparable DRSP concentrations to CrCL >80 ml/min; increased by 37% in CrCL 30-49 ml/min
- Hepatic impairment: DRSP exposure increased 3-fold in moderate hepatic impairment
