Bladder Flashcards
Bladder first
tier: exercise, lifestyle, and complementary therapies
Bladder second
tier: pharmacotherapies
Anti-muscarinic agents
Beta-adrenergic therapy
Initial agent depends on side effect profile and insurance coverage
Anti-muscarinics most
Most commonly prescribed
Anti-muscarinics act primarly
Act primarily by increasing bladder capacity and decreasing urgency through blockade of muscarinic receptor stimulation by acetylcholine during bladder storage
Anti-muscarinics start
Start lowest dose and titrate up (if needed) after 2 weeks
Anti-muscarinics f/u
Start lowest dose and titrate up (if needed) after 2 weeks
Anti-muscarinics CI
CI: uncontrolled tachyarrhythmias, myasthenia gravis, gastric retention and narrow angle-closure glaucoma
Anti-muscarinics AE
AE: urinary retention, dry mouth, constipation, blurred vision for near objects, tachycardia, drowsiness, and decreased cognitive function
Beta3-adrenoceptor agonist (mirabegron
Promotes selective beta receptor stimulation of the detrusor muscle to enhance smooth muscle relaxation.
Mirabegron - Initial medication and as different choice for patients who do not tolerate or respond to antimuscarinic medications
Are at risk for central nervous system side effects (eg, dementia), orr have a contraindication to antimuscarinic medication.
Mirabegron maybe useful
for patients already taking a cholinesterase inhibitor for whom it is preferable to avoid adding antimuscarinic agents.
Mirabegron has similar efficacy to
antimuscarinics but may be somewhat better tolerated.
Mirabegron - Close monitoring
Close monitoring – monitor for new-onset urinary retention by measuring at f/u in 4 to 6 weeks or has any new symptoms
Mirabegron adverse effects
– CI in severe or uncontrolled HTN
HTN – monitor BP
Dry mouth, constipation
Urinary retention
Can use anti-muscarinic and
beta 3 agonist medications together
BPH increases as men
age and can contribute to urinary symptoms that may benefit from medical or surgical treatment.
treatements for BPH
Lifestyle modifications
Alpha-adrenergic receptor blockers
Phosphodiesterase type 5 inhibitors
5-alpha reductase inhibitors to prevent progression
Alpha-adrenergic receptor blockers initial
therapy in most patients with LUTS/BPH
Alpha-adrenergic receptor blockers bladdder outlet
outlet obstruction (BOO) is primarily mediated by alpha-1 adrenergic receptors located on prostatic smooth muscle, which are upregulated in the stromal glandular hyperplasia seen in BPH.
Alpha-adrenergic receptor blockers blcoking
signaling through the alpha-adrenergic receptorsleads to relaxation of the smooth muscle of the bladder neck and the prostatic urethra.
Alpha-adrenergic blockers - SE
SE: dizziness and rhinitis; hypotension
Alpha-adrenergic blockers - Agents with greater
Agents with greater selectivity have fewer systemic SE but are associated with a higher frequency of retrograde or anejaculation (8 to 28 percent).
Alpha-adrenergic blockers patietns
prescribed alpha-1adrenergicblockers should be counseled about the possibility of intraoperative floppy iris syndrome (IFIS).
Phosphodiesterase type 5 inhibitors - used in men with
Used in men with BPH-related symptoms and ED
