## Biological Motivation

Fioricet is a prescription drug that is a combination of acetaminophen (a pain reliever), butalbital (a barbiturate derivative), and caffeine. Acetaminophen works by reducing the production of prostaglandins, which are substances produced in the body that trigger pain. Butalbital aids in muscle relaxation and helps relieve tension headaches and migraines. Caffeine increases blood flow to the brain, making it easier to think more clearly when you're tense or anxious.
