It is a barbiturate derivative drug. It possesses anaesthetic, anticonvulsant, sedative and hypnotic properties. In the United Kingdom, it was known as Quinalbarbitone. Secobarbital binds at a distinct binding site associated with a Cl<sup>-</sup> ionopore at the GABA<sub>A</sub> receptor, increasing the duration of time for which the Cl<sup>-</sup> ionopore is open. The post-synaptic inhibitory effect of GABA in the thalamus is, therefore, prolonged."}]
