Final answer:
Anticholinergic drugs, such as oxybutynin, are commonly used to treat bladder spasm by relaxing the muscles of the bladder and reducing spasms.
Step-by-step explanation:
The drug commonly used to treat bladder spasm is called anticholinergics. Anticholinergics work by blocking the action of acetylcholine, a neurotransmitter that stimulates muscle contractions. By blocking acetylcholine, anticholinergics help relax the muscles of the bladder, reducing bladder spasms.
One example of an anticholinergic drug used to treat bladder spasm is oxybutynin. Oxybutynin is available in different forms, including tablets, patches, and extended-release capsules.
It's important to note that the use of any medication should be prescribed and monitored by a healthcare professional to ensure it is safe and appropriate for the individual's specific condition.
