How Ortho Tri-cyclen 28 Day works
Progesterone analogs like norgestimate decrease the frequency of gonadotropin releasing hormone pulses from the hypothalamus, decreasing follicle stimulating hormone and luteinizing hormone. These actions prevent ovulation.
Ortho Tri-cyclen 28 Day suppresses the hypothalamo-pituitary-axis, reducing androgen synthesis. It also induces production of sex hormone binding globulin, which decreases free testosterone. These actions together result in less testosterone being available to stimulate sebaceous glands, resulting in effective treatment of some forms of acne.
