QuestionChoice
This is incorrect. Whilst oxybutinin is used in overactive bladder by reducing the parasympathetic activity on the bladder wall, this is achieved via its anti-muscarinic properties, not muscarinic agonism. Since parasympathetic innervation stimulates bladder wall contractility, oxybutynin aims to antagonise this process to treat an overactive bladder.

e
It is a muscarinic agonist used to treat overactive bladder by reducing the parasympathetic activity on the bladder wall
QuestionChoice
This is correct. Oxybutinin is an anti-muscarinic medication that works by reducing the parasympathetic activation of the bladder wall. This reduces bladder wall contractility and hence helps to treat an overactive bladder.

a
It is an anti-muscarinic used to treat overactive bladder by reducing the parasympathetic activity on the bladder wall
QuestionChoice
This is incorrect. Whilst oxybutinin does work by reducing parasympathetic activity on the bladder wall, it is used to treat overactive bladder, not overflow incontinence. Reducing parasympathetic activity helps to reduce the bladder wall contractility and hence helps in urge incontinence (a.k.a. an overactive bladder)

d
It is an anti-muscarinic used to treat overflow incontinence by reducing the parasympathetic activity on the bladder wall
QuestionChoice
This is incorrect. Oxybutinin is an anti-muscarinic medication that works by reducing the parasympathetic activation of the bladder wall. This reduces bladder wall contractility and hence helps to treat an overactive bladder.

c
It is an anti-muscarinic used to treat overflow incontinence by reducing the sympathetic activity on the bladder wall
QuestionChoice
This is incorrect. Whilst oxybutinin is an anti-muscarinic used in overactive bladder, it does this via reducing parasympathetic, not sympathetic activity. Parasympathetic innervation is responsible for bladder wall contraction and hence this needs to be targeted in overactive bladder.
