Introduction
Ulipristal tablet is a selective progesterone receptor modulator used mainly as emergency contraception following unprotected intercourse or contraceptive failure. It contains ulipristal 5mg tablets as its chemical composition and acts by modulating the effects of progesterone, an essential hormone in the reproductive system. This medication, also known under various brand names internationally, offers a potent and effective option to prevent unintended pregnancy when taken within 120 hours (5 days) after unprotected sex. The ulipristal tablet 5mg is also indicated for other gynecological uses such as treatment of uterine fibroids under specialist guidance.
Mechanism of Action
Ulipristal tablet functions primarily by binding to progesterone receptors, acting as a selective progesterone receptor modulator. It exhibits both antagonist and partial agonist effects at these receptors in tissues such as the uterus, ovaries, and hypothalamus. The main contraceptive mechanism is the inhibition or delay of ovulation by suppressing or delaying the luteinizing hormone (LH) surge that triggers follicular rupture and egg release. Additionally, ulipristal 5mg tablets may reduce endometrial thickness, potentially affecting the uterine environment to prevent embryo implantation. However, the major recognized effort is ovulation delay or inhibition, distinguishing it from other contraceptives that act post-fertilization.
Uses and Indications
Emergency contraception: To prevent pregnancy after unprotected sexual intercourse or contraception failure, ideally taken within 120 hours.
Treatment of uterine fibroids: In some cases, under specialist supervision, ulipristal is used for nonsurgical management of symptomatic fibroids.
Off-label uses: Occasionally explored for other gynecological conditions due to its progesterone receptor modulating actions.
Efficacy and Clinical Evidence
Clinical trials have demonstrated that ulipristal acetate, delivered as ulipristal 5mg tablets, is highly effective in preventing pregnancy when taken up to 5 days post-unprotected sex. Its efficacy is superior or comparable to other emergency contraceptive methods such as levonorgestrel. Ulipristal's ability to delay ovulation even when administered near the LH surge is key to its high efficacy rate
Side Effects and Safety Profile
Common side effects of ulipristal tablet include:
Headache
Nausea
Abdominal pain or cramps
Fatigue
Dizziness
Most side effects are mild and transient. It is generally well tolerated and considered safe for use by women of reproductive age not currently pregnant.
Contraindications and Precautions
Known or suspected pregnancy (ulipristal should not be used to terminate established pregnancy).
Hypersensitivity to ulipristal or any ingredient in the formulation.
Liver impairment requires caution; avoid if severe liver disease is present.
Women under 18 or postmenopausal women typically are not candidates for this emergency contraceptive.
Drug Interactions
Ulipristal is metabolized primarily by CYP3A4 enzymes; thus, co-administration with strong CYP3A4 inducers (e.g., rifampicin, carbamazepine) may reduce effectiveness.
Caution with other hormonal contraceptives as ulipristal may interfere with their efficacy during and shortly after use.
Warnings and Regulatory Status
Ulipristal acetate tablets are approved by regulatory agencies globally for emergency contraception and specific gynecological uses. Regular use or repeated dosing within one menstrual cycle is not recommended. The medication is often listed on essential medicine lists, reflecting its clinical importance.
