Why is this medication prescribed?

Belladonna alkaloid combinations and phenobarbital are often prescribed together to treat various conditions, primarily gastrointestinal issues such as irritable bowel syndrome (IBS), stomach cramps, and spasms. Belladonna alkaloids help to relax smooth muscles in the digestive tract, reducing spasms and cramping. Phenobarbital is a barbiturate that can also help to relieve muscle spasms and may have sedative effects.

The combination of these medications can help alleviate symptoms associated with gastrointestinal disorders, such as abdominal pain, cramping, and discomfort.
