Q

which alpha antagonists are associated with first dose syncope and what should be done about it

A

doxazocin and terazosin- start at low dose and titrate up- also take HS. This is not required with the others as they have greater selectivity for alpha 1a receptor which predominates in prostate, bladder neck, and urethra- these other 3 also have more constant drug concentrations when taken with meal

Q

name anticholinergics for UI-how do they work

A

darifenacin, fesoterodine, oxybut, solfenacin, tolteridine, trospium. Work- improve bladder capcity, improve urge sx, enhance QOL and reduce incontinence

19
Q

what is mirabegron- what is it for/ SE?

A

beta 3 agonist for urge incontinence. AE= HTN, tachy, nasopharyngitis, UTI. Uncommon QT

20
Q

absolute CI to COC

A

breast cancer, cerobrovascular disease or hx, valvular heart idsease, current or past clot, diabetes with micovascular complications, less than 6 weeks post partum if breastfeeding, migraines with aura at any age, HTN, smoker over 35

21
Q

what generation of progestins are less andorgenic and why is this important

A

third gen (desorgestrel, norgestimate)- better for acne

22
Q

which progestin is not approved for contraception, but only for acne

A

cyproterone acetate

23
Q

what might drospirenone be useful for

A

a progestin- related to aldosterone antagonist spironolactone- both progestin and antiandrogenic activity therefore may be good for PMDD. However, might have higher risk VTE

24
Q

what is the window for taking progestin only pills

A

3 hours- or use backup

25
Q

T/F- continuous COC dosing can only be done with monophasic

A

F- any with estrogen less than 50mcg which is all in Canada can be used

26
Q

when is breakthrough bleeding common with contraception? when should it stop?

A

first 3-6 months- less or stopped after

27
Q

lengths of time to best effect of emergency contraception

A

7 days copper, 3 days plan B,

28
Q

difference between 1’ and 2’ dysmennorhea

A

both abdominal and pelvic pain associated with menses. 2’ has underlying cause of organic pathology (endometriosis, obstructed uterine flow, etc) vs 1’ has no identifiable cause

29
Q

non pharm for dysmennorhea

A

heat, exercise, smoking cessation

30
Q

pharm for dysmennorhea-how long to determine if working?

A

NSAIDs at onset of menses for 2-3 days scheduled with LD if needed, acet only ever if CI to NSAIDs, CHC. Need 3-6 month trial

31
Q

sign might be endometriosis vs dysmen

A

pain persists after mentrual day 2, dyspareunia, infertility

32
Q

how to manage endometriosis pain

A

NSAID or opioid first, then COC or progest only, then GnRH analogue or IUD

33
Q

comment on Gonadotropin releasing hormone analogues (use, efficacy, dosage forms, se), what is used in conjunction

A

inhibit secretio of LH and FSH,not more effective than COC or progestin for pain, not good for endometriomas, nafarelin is intranasal, goserelin is SC, leuproide is IM, none more effective vs others. SE= hypoestrogenic state (hot flash, insomnia, mood changes, vaginal atrophy, decrease BMD). Hormone therapy is added back for this: estrogen and medroxyprogesterone acetate or norethindrone alone

34
Q

what is danazol

A

androgen agonist for endometriosis, can be effective for dysmennorhea portion, limtied by SE (androgenic= hirsutism, acne, negative effect of lipids)

35
Q

how is clomiphene dosed for endometriosis associated infertility

A

50mg daily f5d starting on day 5 if bleeding, but any day if none- helps induce ovulation. Limit to 3 cycles- if no result, quit.

36
Q

drugs of choice for ED, CI

A

PDE5 inh- silden, tadal, varden. CI= nitrates, symptomatic hypotension,

37
Q

what are the injections given for ED

A

prostaglandin E analogues- alprostadil (intracavernosal or urethral instillation)

38
Q

counselling on PDE5inh

A

take 30-60 minutes before activity, efficacy depends on mental arousal, high fat meal delays absorption except in tadalafil, CI with nitrates (24 hours, 48 for tadal), common SE flushing, HA, dyspepsia (transiet), transient visual disturbance (blue/green color hard to distingush, blurry, increased light sensitive, etc- most common with silden) , may take a few times before works so don’t be discouraged first try

39
Q

first line therapy for vasomotor sx (and what that is)- what if you’ve had a hysterectomy? What if 1st line is CI?

A

vaso sx=hot flashes and night sweats. Estrogen; if no hysterectomy, need combined HT or do non hormonal.If hysterectomy can do estrogen alone. If CI estrogen, non hormonal therapy only

40
Q

non pharm for hot flashes

A

dress in layers, fan, cool drinks, smoking cessation, stretching, yoga possibly

41
Q

how long does it take to see benefit with estrogen used for menopausal sx

A

4 weeks on standard dose, 8-12 if low

42
Q

why is progesterone always added to estrogen in menopause? what dose?

A

to reduce risk of endometrial hyperplasia; use MPA 5mg daily if cyclical regimen (estrogen all the time, MPA for days 1-14, expect withdrawal bleed when estrogen is stopped), and 2.5 mg daily for continuous (minimum 1.5)

43
Q

how long should estrogen therapy be used for for menopause
