Pan-tranquil - General Information
A carbamate with hypnotic, sedative, and some muscle relaxant properties, although in therapeutic doses reduction of anxiety rather than a direct effect may be responsible for muscle relaxation. Pan-tranquil has been reported to have anticonvulsant actions against petit mal seizures, but not against grand mal seizures (which may be exacerbated). It is used in the treatment of anxiety disorders, and also for the short-term management of insomnia but has largely been superseded by the benzodiazepines. (From Martindale, The Extra Pharmacopoeia, 30th ed, p603) Pan-tranquil is a controlled substance in the U.S.
Pharmacology of Pan-tranquil
Pan-tranquil is an anxiolytic drug. It was the best selling minor tranquilizer for a time but has largely been replaced by benzodiazepines. Pan-tranquil has most of the pharmacological effects and dangers of the barbiturates (though it was marketed as being safer). However, it is less sedating at effective doses. It is reported to have some anticonvulsant properties against absence seizures, but can exacerbate generalized tonic-clonic seizures. It has also been used as a hypnotic (sleeping pill). However, its is currently only licensed as an anxiolytic and it is a third or fourth-order choice.

Mechanism Of Action: Pan-tranquil's mechanism of action is not known. It has been shown in animal studies to have effects at multiple sites in the central nervous system, including the thalamus and limbic system. Pan-tranquil binds to GABAA receptors which interrupt neuronal communication in the reticular formation and spinal cord, causing sedation and altered perception of pain.
