Q

Why would pt benefit from levonorgestrel-containing IUD vs Copper IUD

A

Levonorgestrel IUDs decrease menstrual blood loss up to 50% and the severity of dysmenorrhea

Q

Mechanism by which Cytochrome P-450 increases production of liver enzymes and decrease effect of COCs

A
  • Cytochrome P450 (CYP450) enzymes in the liver and gut metabolize COCs.

  • Ovum/tubal transport is altered
  • Cervical mucus thickens, inhibiting sperm transport
  • Implantation is inhibited by suppression of the endometrium and alteration of uterine secretions.

A

Etonogestrel (a progestin-only implant)

Q

Physiologic effects exerted by estrogen component of CHCs and what serum level is decreased?

A

The estrogenic component acts by suppressing secretion of FSH, preventing maturation of a follicle as well as potentiation of the action of the progestational agent.

27
Q

Effectiveness of patch in obese patients

  • Body weight is associated with lower serum levels of the hormones in patch users, but only limited and inconsistent evidence suggests that a person weighing more than 90kg (198lbs) may be at higher risk of pregnancy
