Levonorgestrel/Etinilestradiol Durban (Ethinylestradiol, Levonorgestrel)

Levonorgestrel/Etinilestradiol Durban is a combined oral contraceptive used within the hormonal contraceptive pathway to prevent unintended pregnancy.

• Contraception: Prevents pregnancy in women of childbearing potential.
• Menstrual cycle regulation: Helps to establish regular menstrual bleeding patterns.
• Acne improvement: May reduce acne associated with androgen excess.

• Ethinylestradiol binds to estrogen receptors while levonorgestrel binds to progesterone receptors, together suppressing the mid‑cycle luteinizing hormone surge, inhibiting ovulation, inducing changes in the endometrial lining, and increasing cervical mucus viscosity, thereby reducing the likelihood of fertilisation and implantation.
