Butalbital
Butalbital
Butalbital (pronounced: byoo-TAL-bi-tal) is a barbiturate with an intermediate duration of action. It has the same chemical formula as phenobarbital except for one additional oxygen atom.
Etymology
The term "Butalbital" is derived from "butyl", referring to the four-carbon butyl group in its chemical structure, and "barbital", a common suffix for barbiturates.
Usage
Butalbital is often combined with other medications, such as paracetamol (acetaminophen) or aspirin, and is commonly prescribed for the treatment of pain and headache. The various formulations are FDA approved for the treatment of tension headaches.
Mechanism of Action
Butalbital works by slowing down the central nervous system and causing relaxation of the muscle tension. It does this by mimicking the action of GABA, an inhibitory neurotransmitter in the brain.
Side Effects
Common side effects of Butalbital include drowsiness, dizziness, and feeling intoxicated. Serious side effects can include dependency and withdrawal symptoms on abrupt discontinuation.
