Documented Uses

• For the induction of anesthesia prior to the use of other general anesthetic agents and for induction of anesthesia for short surgical, diagnostic, or therapeutic procedures associated with minimal painful stimuli.
• Hexobarbital (Class: Depressants and Tranquilizers, Added Date: 10-1998)
• Drugs used to induce drowsiness or sleep or to reduce psychological excitement or anxiety.
• QN05C - Hypnotics and sedatives
• Hexobarbital binds at a distinct binding site associated with a Cl- ionopore at the GABA-A 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.
