Non-selective: Terazosin, doxazosin
Selective: Tamsulosin (Flomax), alfuzosin, silodosin)
Alpha receptors are on the iris dilator muscle of the eye so most of these patients will have a floppy iris syndrome during cataract surgery
Explain the different types of urinary incontinence
Urge, stress, mixed, functional, overflow
Urge: sudden and unstoppable urge to urinate. Associated with neuropathy
Stress: Urine leaks out during any form of exertion
Mixed: a combination of urge and stress
Functional: No abnormality in the bladder, but patient may be cognitively or physically impaired thus hindering access to toilet
Overflow: Leakage that occurs when quantity of urine stored in bladder exceeds capacity. Often occurs without urge to urinate (BPH most common cause)
What is first line treatment for urge incontinence and mixed?
Anticholinergics (oxybutynin) or Beta-3 agonists (Mirabegron)
What is first line treatment for stress incontinence?
Lack of effective options and not FDA approved
Sudafed and duloxetine
are extended release or immediate release preferred for antimuscarinics for incontinence and why? What drugs are selective for M3 and why are they better?
ER due to lower risk of dry mouth
Solifenacin (Vesicare) is selective for M3 so less CNS side effects than non-selective such as oxybutynin (ditropan)

What is the difference in MOA of how Ivacaftor, Lumacaftor, Tezacaftor, and Elexacaftor work for CF?
Ivacaftor works by increasing the time the CFTR channels remain open (NOT approved for use in the homozygous F508del mutation)
Lumacaftor/Tezacaftor/Elexacaftor help correct the CFTR folding defect which increases the amount of CFTR delivered to the cell surface
-approved for use in the homozygous F508del mutation
Take all of them with high fat meal
