TRI-LINYAH (ethinyl estradiol)
TRI-LINYAH is indicated for the treatment of Acne Vulgaris.
How TRI-LINYAH Works
Tri-Linyah prevents pregnancy primarily by suppressing ovulation. Secondary mechanisms include changes in cervical mucus to inhibit sperm penetration and alterations to the endometrium to reduce the likelihood of implantation. In the context of acne, the combination of ethinyl estradiol and norgestimate increases sex hormone-binding globulin (SHBG) and decreases free testosterone. While these changes are thought to counter the androgenic stimulation of sebum production, a definitive relationship between these specific hormonal shifts and reduced acne severity has not been established.
