Valnoctamide is a valproic acid derivative associated with a decreased risk for congenital abnormalities and developed by Beersheva Mental Health Center for treatment mania. Valnoctamide has been marketed as an anxiolytic and sedative in several European countries (as Nirvanil), including Italy, Holland, and Switzerland, until the year 2000 but was not actively promoted as an anticonvulsant. It was marketed in the U.S. as Axiquel by McNeil Laboratories in the 1970s. In mice, valnoctamide has been shown to be distinctly less teratogenic than valproic acid. Injection of 3 mkmol ⁄ kg at day 8 of gestation produced only 1% exencephaly (as compared to 0–1% in control mice and 53% in valproate-treated mice). Embryolethality rates showed similar results: 52% with valproate versus 5% in the controls and 2% with valnoctamide. Valnoctamide's patent is expired, and it is not the property of any major pharmaceutical company. Valnoctamide has potential as a therapy in epilepsy including status epilepticus (SE) and neuropathic pain and is currently being developed for the treatment of mania and Schizoaffective Disorder. In clinical trials, Valnoctamide was well tolerated but lacked efficacy in the treatment of symptoms in patients with acute mania.

Chlorhexadol (or Chloralodol), a hypnotic compound which is included in the list of Schedule III drugs of the United States Controlled Substances Act.

Ethyl loflazepate (Lof) has been used widely as a sedative and anxiolytic agent for nearly 20 years. Ethyl loflazepate was designed to be a prodrug for descarboxyloflazepate, its active metabolite. It is the active metabolite which is responsible for most of the pharmacological effects rather than ethyl loflazepate. The main metabolites of ethyl loflazepate are descarbethoxyloflazepate, loflazepate and 3-ydroxydescarbethoxyloflazepate which are the benzodiazepine receptor agonists. Ethyl loflazeplate is commercialized in Mexico, under the trade name Victan. It is officially approved for the following conditions Anxiety: Post-trauma anxiety; Anxiety associated with severe neuropathic pain; Generalized anxiety disorder (GAD); Panic attack; Delirium tremens. It possesses anxiolytic, anticonvulsant, sedative and skeletal muscle relaxant properties. Accumulation of the active metabolites of ethyl loflazepate are not affected by those with renal failure or impairment. The symptoms of an overdose of ethyl loflazepate include sleepiness, agitation and ataxia. Hypotonia may also occur in severe cases. These symptoms occur much more frequently and severely in children. High doses of the antidepressant fluvoxamine may potentiate the adverse effects of ethyl loflazepate.

Etizolam is an analogue of benzodiazepine that contains thienotriazolodiazepine group. The drug was developed and approved in Japan and now is used in Japan, Italy and India for the treatment of anxiety disorders. Etizolam exerts its action through activation of GABA A receptors, moreover, the agonistic behavior was shown on isolated neurons. There are several cases when etizolam dependence was reported. In many countries the drug is recognized as a psychoactive substance and its distribution is illegal there.

Fluanisone, a butyrophenone derivative, is a neuroleptic agent, which was used in the treatment of schizophrenia and mania. Veterinary formulation fentanyl/fluanisone (Hypnorm) is used for rodent analgesia during short surgical procedures. Hypnorm is a combination often used as a neuroleptanalgesic and anaesthetic. Fentanyl-fluanisone has stimulating effects on the amount of spike-wave discharges, but not in a dose-dependent manner. A low dose of 0.01 mg/kg fentanyl with 0.5 mg/kg fluanisone causes a large increase in epileptic activity. This effect is larger than with a middle dose of 0.1 mg/kg fentanyl and 5 mg/kg fluanisone and much larger than with a high dose of 0.2 mg/kg fentanyl with 10 mg/kg fluanisone. The last two doses cause a prolonged anaesthetic state in rats. Fluanisone alone in the same doses as in the mixture induces a large dose-dependent increase in spike-wave activity, with only a small effect on spike frequency. This might be caused by the antagonistic action of this drug at dopamine receptors.

Fludiazepam is a potent benzodiazepine and 2ʹ-fluoro derivative of diazepam,[3] originally developed by Hoffman-La Roche in the 1960s. Fludiazepam is marketed in Japan and Taiwan under the brand name Erispan. Fludiazepam exerts its pharmacological properties via enhancement of GABAergic inhibition. Fludiazepam has 4 times more binding affinity for benzodiazepine receptors than diazepam. Fludiazepam possesses anxiolytic, anticonvulsant, sedative, hypnotic and skeletal muscle relaxant properties.

Moperone is a first-generation (typical) antipsychotic drug that belongs to the butyrophenone type approved in Japan for the treatment of schizophrenia. It has higher antagonist affinity for D2- than 5-HT2A-receptors. It also has high binding affinity for sigma receptors. It was indicated for schizophrenia, paranoid state, psychoses, epilepsy,alcohol withdrawal syndrome. It can induce extrapyramidal motor side effects, insomnia, and thirst, but it displays generally low toxicity.

Perazine (Taxilan) is a moderate-potency typical antipsychotic of the phenothiazine class. Perazine is an older antipsychotic drug first introduced in the 1950s. It is suggested to have a low level of side effects (especially for movement disorders). Its use is regional and restricted to countries like Germany, Poland, the Netherlands and the former Yugoslavia. Perazine has being shown to be a potent inhibitor of human CYP1A2. It acts as a dopamine antagonist.

Etifoxine (etafenoxine, StresamⓇ) is a non-benzodiazepine anxiolytic with an anticonvulsant effect. It was developed in the 1960s for anxiety disorders and is currently being studied for its ability to promote peripheral nerve healing and to treat chemotherapy-induced pain. In addition to being mediated by GABA-A2 receptors like benzodiazepines, etifoxine appears to produce anxiolytic effects directly by binding to 2 or 3 subunits of the GABAA receptor complex. It also modulates GABAA receptors indirectly via stimulation of neurosteroid production after etifoxine binds to the 18 kDa translocator protein (TSPO) of the outer mitochondrial membrane in the central and peripheral nervous systems, previously known as the peripheral benzodiazepine receptor (PBR). Therefore, the effects of etifoxine are not completely reversed by the benzodiazepine antagonist flumazenil. Etifoxine is used for various emotional and bodily reactions followed by anxiety. It is contraindicated in situations such as shock, severely impaired liver or kidney function, and severe respiratory failure. The average dosage is 150 mg per day for no more than 12 weeks. The most common adverse effect is drowsiness at the initial stage. It does not usually cause any withdrawal syndromes. In conclusion, etifoxine shows less adverse effects of anterograde amnesia, sedation, impaired psychomotor performance, and withdrawal syndromes than those of benzodiazepines.

Mosapramine (Cremin) is used to treat chronic schizophrenia in Japan. It is a potent dopamine antagonist with high affinity to the dopamine receptor subtypes 2, 3 and 4, and with moderate affinity for the 5-HT2 receptors
