Final answer:
To treat Overactive Bladder (OAB), medications such as Tolterodine, Oxybutynin, Solifenacin, Darifenacin, and Mirabegron are commonly prescribed to relax the bladder muscle and reduce spasms.
Step-by-step explanation:
The five drugs commonly used to treat Overactive Bladder (OAB) are Tolterodine, Oxybutynin, Solifenacin, Darifenacin, and Mirabegron. These medications are anticholinergics or beta-3 agonists, which help control the symptoms of OAB by relaxing the bladder muscle and reducing muscle spasms. Most overactive bladder drugs used to address the symptoms work by targeting the cholinergic receptors in the bladder, except for Mirabegron which works as a beta-3 adrenergic agonist, stimulating relaxation of the bladder muscle.
