increase creatinine but no kidney effect; ok up to 30mmol or 30%

27
Q

What is the MOA of oxybutynin?

A

Inhibits M2 and M3 receptors in bladder to stop muscarinic ACh action –>antispasmodic
No antinicotinic effects
Avoid in GI obst, narrow angle glaucoma, GORD

28
Q

Which type of incontinence can you use oxybutynin?

A

Urge incontinence

29
Q

What are the other types of antispasmodics, and how are they classified

A

There are nonselective antimuscarinics which act on M2 and M3 receptors eg oxybutynin and tolterodine. Can cross BBB to lead to less dizziness and cog symptoms

There are M3 selective eg solifenacin. Cannot easily cross BBB- M3 selective, increase risk dry mouth at higher dose. Safer if over 65

A

Single dose at 65

A

No
