Q

Urinary Incontinence

What are the types of urinary incontinence?

A
  • overactive bladder (OAB) or urge (UUI)= bladder overactivity; urgency, frequency, large amount of urinary leakage, may be unable to reach toilet, frequent nocturia, nocturnal incontinence; micturition occurs > 8 times a day
  • stress (SUI)= urethral underactivity; leaking during physical activity, typically a small amount of leakage; risk factors: pregnancy, childbirth, menopause, cognitive impairment, obesity, aging
  • overflow= urethral underactivity and/or bladder underactivity; bladder leakage due to disease or medication, increased post void residual urine volume, straining to void, interrupted stream; associated with BPH
  • functional= difficult reaching toilet in time due to physical limitations
  • mixed= often stress and urge, but can be a combination of any

25
# Urinary Incontinence What are the 2 receptors found on the detrusor muscle that are targeted in overactive bladder (OAB)?
- beta adrenergic receptors - muscarinic receptors (M2 and M3)
26
# Urinary Incontinence What is the mechanism of action of antimuscarinics?
supressed the involuntary bladder contractions by blocking muscarinic receptors in the bladder
27
# Urinary Incontinence What drugs are antimuscarinics?
- oxybutynin - tolterodine - fesoterodine - trospium - darifenacin (selective M3) - solifenacin (selective M3)
28
# Urinary Incontinence What dosage form of oxybutynin may be preferred?
transdermal patch | due to less SE than IR tablet, but similar efficacy
29
# Urinary Incontinence What are the patient counseling points for oxybutynin patch?
rotate sites and avoid same site within 7 days, avoid sunlight on patch
30
# Urinary Incontinence What drugs for overactive bladder (OAB) require renal adjustments?
- tolterodine - fesoterodine - trospium
31
# Urinary Incontinence What drugs for overactive bladder (OAB) require hepatic adjustments?
- tolterodine - darifenacin
32
# Urinary Incontinence What medication used for overactive bladder (OAB) may cause QT prolongation?
tolterodine
33
# Urinary Incontinence What is the important patient counseling point for trospium?
take on empty stomach
34
# Urinary Incontinence What CYP isoenzyme is used by antimuscarinics?
CYP3A4 and 2D6 | except trospium
35
# Urinary Incontinence What are the contraindications to antimuscarinic agents?
- narrow angle glaucoma - urinary retention - severely decrease GI motility
36
# Urinary Incontinence What drugs are beta3 adrenergic receptor agonists?
- mirabegron - vibegron
37
# Urinary Incontinence What are the adverse effects of beta3 agonists?
- headache - nasal congestion - mirabegron= cardiovascular effects (hypertension, tachycardia, palpitations)
38
# Urinary Incontinence What are the contraindications of mirabegron?
pregnancy or breastfeeding
39
# Urinary Incontinence What are the drug interactions of mirabegron?
CYP2D6 inhibitor
40
# BPH What are the risk factors of BPH?
- advancing age - levels of endogenous testosterone and dihydrotestosterone levels - black race - obesity - diabetes - high levels of EtOH consuption - physical inactivity - medication
41
# BPH How is BPH diagnosed?
- digital rectal exam - prostate specific antigen (PSA) - international prostate symptom score (I-PSS)
42
# BPH When should pharmacologic treatment be initiated in BPH?
I-PSS score 8+ or bothersome symptoms
43
# BPH What are the pharmacologic treatment options for BPH?
- alpha adrenergic receptor antagonists - 5alpha reductase inhibitors - phosphodiesterase type 5 (PDE5) inhibitors
44
# BPH What drugs are alpha adrenergic receptor antagonists?
- doxazosin - terazosin - alfuzosin, tamsulosin, silodosin (alpha 1 selective, uroselective)
45
# BPH What alpha adrenergic antagonists requires renal adjustment?
silodosin
46
# BPH What alpha adrenergic antagonists require titrations?
non-selective agents (doxazosin, terazosin)
47
# BPH What are the adverse effects of alpha adrenergic agents?
- dizziness, syncope - hypotension - floppy iris - headache - 1A, uroselective agents= erectile dysfunction, anejaculation, nasal congestion, flu-like symptoms
48
# BPH T/F: Alpha adrenergic antagonists decrease the size of the prostate.
false, size of prostate is not affected, but I-PSS scores can be decreased 4-7 points= effective agents
