Tri-Lo-Marzia is a triphasic oral contraceptive that contains a combination of ethinyl estradiol and trimegestone [1]. It is used to prevent pregnancy [1].
How does Tri-Lo-Marzia work?
Tri-Lo-Marzia prevents pregnancy through three mechanisms: it inhibits ovulation, alters the cervical mucus to make it harder for sperm to penetrate, and changes the lining of the uterus, making it less receptive to implantation [1].
What are the active ingredients in Tri-Lo-Marzia?
The active ingredients in Tri-Lo-Marzia are ethinyl estradiol, a synthetic estrogen, and trimegestone, a progestin [1]. These hormones are present in different amounts across the three phases of the pill pack [1].
