A
  1. Off-label replacement therapy for menopausal women (to see if it would increase libido; off-label means not approved by FDA)

3.__________: (Cholestatic ______or ____ cancer): Monitor LFTs. This only occurs with 17-alpha-alkylated androgens, which should not be used long term

A
  1. Virilization (male enhancing) in women and girls and boys - in women can cause acne, deep voice, male pattern baldness, increased ibido, clitoral enlargement and menstrual irregularities.
  2. Premature epiphyseal closure: bone fusing, basically. If testosterone is used in children, monitor bone growth!

Q

How do PDE-5 inhibitors help erectile dysfunction?

They take the med (PDE-5), as well as having a _____ _____. ____________ nervous system is stimulated and impacts ____

Know that the result is..

A

They take the med (PDE-5), as well as having a sexual stimulus/arousal. Parasympathetic nervous system is stimulated and impacts cGMP.

Know that the result is vasodilatation of the arteries in the penis (arterial engorgement), in addition to reduced venous outflow- resulting in penis engorged with blood = erection

  2. Rare: vision changes, sudden hearing loss, vertigo
17
Q

Priapism is a painful erection lasting over __ hours- for ALL PDE5s- by 4 hrs go to ED because it can damage penile tissue, causing permanent loss of _____

Need to have blood aspirated from corpus cavernosum and ______ w a _________

A

Priapism is a painful erection lasting over 6 hours- for ALL PDE5s- by 4 hrs go to ED because it can damage penile tissue, causing permanent loss of potency.

Need to have blood aspirated from corpus cavernosum and irrigation w a vasoconstrictor

18
Q

Contraindicated drugs for PDE-5 inhibitors

A

Nitroglycerin/Nitrates- ABSOLUTELY CONTRAINDICATED FOR MEN TAKING NITRATES- need at least 24 hrs in between these meds for safety, and longer if using a CYP3A4 inhibitor or hepatic or renal pathology

Alpha-blockers (dilate arterioles which lead to hypotension)

Inhibitors of cytochrome P450 (CYP3A4)- grapefruit juice

19
Q

Two classes of drugs used for management of benign prostatic hyperplasia (BPH)

A

Alpha-blockers/Alpha 1 antagonists

5-alpha reductase inhibitors

20
Q

5-alpha reductase inhibitors name and what’s it for

A

-asteride

For a very large obstruction, mechanical obstruction (with BPH)

21
Q

Alpha-blockers/Alpha 1 antagonists name and

are for

A

-osin
Are for smaller prostates (dynamic obstruction)

22
Q

MOA of Alpha-blockers/Alpha 1 antagonists

A
  • Relaxation of the smooth muscle surrounding the prostate gland
  • Reduces dynamic obstruct of urthera (opening is larger)- they DO NOT reduce prostate size
23
Q

Adverse effects of Alpha-blockers/Alpha-1 antagonists

A

Selective blockers: Can cause abnormal ejaculation

Nonselective blockers:

Increased risk for floppy-iris syndrome with cataract surgery (tell ophthalmologist and postpone alpha-blocker therapy until after)

24
Q

MOA of 5-alpha reductase inhibitors

-_______ the growth of the ______ and causes ____ of the enlarged prostate tissue by _______ a hormone

-Promotes _______ of prostate epithelial tissue (decreases mechanical obstrux)

-Inhibits 5-alpha reductase found ONLY in ________ ________

A

-Delays the growth of the prostate and causes shrinkage of the enlarged prostate tissue by blocking a hormone

-Promotes regression of prostate epithelial tissue (decreases mechanical obstrux)

-Inhibits 5-alpha reductase found ONLY in reproductive tissues

25
Q

Adverse effects of 5-alpha reductase inhibitors (-asteride)

A

Finasteride/Dutasteride:

  • Decreases ejaculate volume and libido
