What is Butalbital, and how does it work (mechanism of action)?
Butalbital/acetaminophen/caffeine is a combination product used to treat headaches.
Butalbital is a medication that depresses the central nervous system.
Butalbital is a softener for pain and fever. It is Tylenol’s active ingredient. Butalbital relieves pain by increasing the threshold of pain, that is, by allowing more pain to occur before a person feels it. By its action on the heat-regulating center of the brain, it decreases fever. In particular, when the temperature is elevated, it tells the center to lower the body’s temperature.
Caffeine has pain-relieving properties and by mechanisms that are not well understood can boost the action of other pain relievers. It may lower the function of nerves in the brain that feels pain. Butalbital/acetaminophen/caffeine was approved in November 1984 by the FDA.
What are the side effects of Butalbital?
Butalbital/acetaminophen/caffeine side effects usually involve lightheadedness, dizziness, shortness of breath, nausea, dry mouth, heart rate increases, and tremors.
Butalbital/acetaminophen/caffeine has a boxed liver toxicity indication when used for extended periods in excessive amounts. To prevent acute liver damage, the dose of acetaminophen should not exceed 4000 mg per day. Butalbital is the development of habit and can be manipulated.
After prolonged periods of barbiturate (butalbital) use, sensitivity, dependency, and physical dependence may occur.
For patients with hypersensitivity to any of its ingredients and patients with porphyria, this medication is contraindicated.
