Week 14 Fall Flashcards
tolterodine (Detrol LA)
MOA
Tolterodine and its active metabolite are competitive antagonists of acetylcholine at muscarinic receptors. In the bladder, this results in relaxation of the detrusor muscle which reduces urinary incontinence, urgency, and frequency symptoms

Efficacy
Decreased symptoms of bladder overactivity

terazosin (Hytrin)
MOA
In hypertension, competitively inhibits post-synaptic alpha1-adrenergic receptors causing vasodilation and decrease in blood pressure
In BPH, competitively inhibits post-synaptic alpha1-adrenergic receptors in the prostate and bladder tissues, decreasing smooth muscle tone and reducing BPH symptoms
terazosin (Hytrin)
Efficacy
Urinary symptoms
Blood pressure
terazosin (Hytrin)
Safety
Standing and sitting blood pressure
terazosin (Hytrin)
BBW
none
terazosin (Hytrin)
Precautions
caution may cause orthostasis with/without syncope, risk highest during initiation, interruption in therapy for a few days, dose increases, concurrent use of other antihypertensives or phosphodiesterase-5 inhibitors; priapism may occur; must rule out prostate cancer prior to initiation; caution in elderly due to orthostasis risk; risk of intraoperative floppy eye syndrome in cataract surgery
terazosin (Hytrin)
ADR
Common: Dizziness, Orthostatic hypotension, Headache, Syncope
Rare: Floppy iris syndrome, Priapism, Angina
terazosin (Hytrin)
Contraindications
Hypersensitivity to terazosin or any component of the product
terazosin (Hytrin)
Dose Adjust
R: none
H:none
oxybutynin (Ditropan XL)
MOA
Oxybutynin has a direct antispasmodic effect on smooth muscle and inhibits the muscarinic action of acetylcholine on smooth muscle. This results in bladder smooth muscle relaxation and suppression of the urge to void.
oxybutynin (Ditropan XL)
Efficacy
Decreased symptoms of bladder overactivity
oxybutynin (Ditropan XL)
Safety
See ADR
Common: Xerostomia, Constipation, Dizziness, Drowsiness, Nausea
Rare: Angioedema, Heat prostration

BBW
none
oxybutynin (Ditropan XL)
Precaution
caution may cause serious hypersensitivity reactions including angioedema and anaphylaxis; cause anticholinergic side effects (i.e. agitation, confusion, drowsiness, dizziness, hallucinations, headache, and/or blurred vision); may increase risk of heat prostration, caution with extreme heat or strenuous exercise; caution in bladder flow obstruction; caution in patients with CAD, heart failure, or arrhythmias; caution in patients with dementia on cholinesterase inhibitors; caution in patients with GI motility disorders or GI obstructive disorders; caution in glaucoma; caution in Parkinson’s disease; caution in BPH; caution in myasthenia gravis; caution in elderly

tamsulosin (Flomax)
MOA
Tamsulosin works as a selective antagonist at alpha-1 receptors in the prostate. Blockade of alpha-1 receptors leads to smooth muscle relaxation in the bladder neck and prostate. This results in improved urine flow rate and symptoms of benign prostatic hypertrophy.
