Reproductive Flashcards
Danazol: Mechanism
Partial agonist of androgen receptor
Danazol: Use (2)
- Endometriosis
2. Hereditary angioedema
Danazol: Side effect (7)
Masculinization Hirsutism Decreased HDL levels Edema Weight gain Acne Hepatotoxicity
Sildenafil, Vardenafil: Mechanism
Inhibits phophodiesterase 5, causing increased cGMP, smooth muscle relaxation in corpus cavernosum, increased blood flow and penile erection
Sildenafil, Vardenafil: Use
Erectile dysfunction
Sildenafil, Vardenafil: Side effects (5)
Headache Flushing Dyspepsia Impaired blue-green color vision Life-threatening hypotension (with nitrates)
Tamsulosin: Mechanism
alpha-1 antagonist inhibiting smooth muscle contraction
Why is tamsulosin unique as an alpha-1 antagonist
Selective for alpha 1A,D receptors on prostate
Vascular receptors = 1B
Tamsulosin: Use
BPH
Terbutaline: Mechanism
Beta-2 agonist -> uterine relaxation
Terbutaline: Use
Reduce premature uterine contraction
Oral contraception: Estrogen and progestin mechanism
Inhibit LH/FSH and prevent estrogen surge (no LH surge = no ovulation)
Oral contraception: Progestin mechanism (2)
Thickening of cervical mucus, preventing access of sperm to uterus
Inhibit endometrial proliferation - less suitable for implantation
Who should not take oral contraceptives (3)?
Smokers > 35 yo (Increased cardiovascular events)
History of thromboembolism or stroke
History of estrogen-dependent tumor
Mifepristone: Mechanism
Competitive progestin receptor antagonist
Mifepristone: Use
Termination of pregnancy
What is administered with mifepristone for termination of pregnancy?
Misoprostol (PGE1)
Mifepristone: Side effects (2)
Heavy bleeding
GI (abdominal pain, nausea, vomiting, anorexia)
Progestins: Use (2)
Oral contraceptives
Treatment of endometrial cancer and abnormal uterine bleeding
Anastrozole: Mechanism
Aromatase inhibitor
Exemestane: Mechanism
Aromatase inhibitor
