About Butalbital (BAC 123)
BAC 123 contains Butalbital, a short-to-intermediate-acting barbiturate used in combination formulations for tension headaches and migraines. It is typically combined with caffeine and acetaminophen (and sometimes codeine) to provide multi-component headache relief.
Benefits of Butalbital (BAC 123)
- Headache Relief: Effective for tension-type headache and migraine combinations.
- Muscle Relaxation: Barbiturate component relieves cranial muscle tension contributing to headache.

How Butalbital Works
Butalbital enhances GABA-A receptor activity, producing CNS depression and skeletal muscle relaxation that reduces the muscle tension component of tension headaches. Combined analgesic and stimulant co-ingredients (acetaminophen, caffeine) address pain and vascular components of headache.
