Butalbital, 5-allyl-5-isobutylbarbituric acid, is a barbiturate with an intermediate duration of action. The different combinations with butalbital is approved. One of them is fioricet with codeine (butalbital, ccetaminophen, caffeine, and codeine phosphate) which is indicated for the relief of the symptom complex of tension (or muscle contraction) headache. Evidence supporting the efficacy and safety of fioricet with codeine in the treatment of multiple recurrent headaches is unavailable. Butalbital is well absorbed from the gastrointestinal tract and is expected to distribute to most tissues in the body. This compound in general may appear in breast milk and readily cross the placental barrier. Monoamine oxidase (MAO) inhibitors may enhance the CNS effects. The mechanism of action for butalbital is proposed the following: this compound binds at a distinct binding site associated with a Cl- ionopore at the GABAA receptor, increasing the duration of time for which the Cl- ionopore is open. The post-synaptic inhibitory effect of GABA in the thalamus is, therefore, prolonged.   NCATS
