Answer 1

Oxybutynin and tolterodine are medications used to treat overactive bladder. Oxybutynin has more anticholinergic side effects compared to tolterodine. Both drugs work by blocking certain receptors in the bladder to decrease muscle contractions.

Step-by-step explanation:

Oxybutynin and tolterodine are both medications used to treat overactive bladder (OAB) by reducing muscle spasms in the bladder. However, there are several differences between the two drugs:

1. Anticholinergic side effects: Oxybutynin has more anticholinergic side effects compared to tolterodine. Anticholinergic side effects can include dry mouth, constipation, blurred vision, and urinary retention.

2. Drug class: Oxybutynin is an anticholinergic medication, while tolterodine is an antimuscarinic medication. Both drugs work by blocking certain receptors in the bladder to decrease muscle contractions.

3. Route of administration: Both drugs are available in different forms such as tablets, extended-release tablets, and patches. However, tolterodine is also available as an oral suspension for pediatric patients.
