Pinazepam, a benzodiazepine derivative, differs from other drugs of its class by the presence of an unsaturated bond, the propargyl group, at the N-1 position. In animals, pinazepam controls anxiety and aggressiveness and exerts anticonvulsant activity. In clinical trials with open or controlled design, pinazepam, compared with diazepam, showed significant and purely anxiolytic action in patients suffering from anxiety with or without somatic manifestations, particularly in gastrointestinal disorders. Even though it is not a specific hypnotic drug, it seems to help patients in whom the physiological course of the sleep is disturbed. Pinazepam is used in the treatment of anxiety and insomnia associated with anxiety.

Arfendazam, a prodrug, is a partial agonist of the benzodiazepine site of GABAA receptors, possesses muscle-relaxant properties.

Tetrazepam was the most widely prescribed muscle relaxant in Germany. After a series of studies, which have shown, that tetrazepam caused cutaneous adverse effects and toxic epidermal necrolysis, the drug was withdrawn from the market.

Lormetazepam (or methyl-lorazepam), possesses hypnotic, anxiolytic, sedative and skeletal muscle relaxant properties. Lormetazepam is not approved for sale in the United States or Canada, though it is licensed in the Netherlands as 1 and 2 mg tablets, under the brand names Loramet and Noctamid and as generic, available from several different manufacturers. Lormetazepam is a short-acting benzodiazepine and is sometimes used in patients who have difficulty in maintaining sleep or falling asleep. Lormetazepam binds to the benzodiazepine receptor which in turn enhances the effect of the GABAA receptor producing its therapeutic effects as well as adverse effects. Lormetazepam appears to be more selective in the type of benzodiazepine receptor it binds to showing a higher affinity for the omega 1 receptor which is responsible for sedation. Changes in electroencephalography can therefore be used to measure the sedative sleep promoting properties of lormetazepam.

KETAZOLAM, a benzodiazepine with an additional d-face-fused heterocyclic ring, possesses anxiolytic, anticonvulsant, sedative and skeletal muscle relaxant properties. It is used for the treatment of anxiety and spasticity.

Brotizolam (marketed under brand name Lendormin) is a sedative-hypnotic thienotriazolodiazepine drug which is a benzodiazepine analog. It possesses anxiolytic, anticonvulsant, hypnotic, sedative and skeletal muscle relaxant properties, and is considered to be similar in effect to short-acting benzodiazepines such as triazolam. It is used in the short-term treatment of severe or debilitating insomnia and in a dose of 0.25 mg can be used as a premedication prior to surgery, this dose was found to be comparable in efficacy to 2 mg flunitrazepam as a premedicant prior to surgery. The drug was developed by a team led by T Nishiyama while working for Takeda Chemical Industries in 1976 in Japan. Brotizolam is not approved for sale in the UK, United States or Canada. It is approved for sale in the Netherlands, Germany, Spain, Belgium, Luxembourg, Austria, Portugal, Israel, Italy, Taiwan and Japan. Insomnia. Brotizolam is prescribed for the short-term treatment, 2–4 weeks only of severe or debilitating insomnia. Insomnia can be described as a difficulty falling asleep, frequent awakening, early awakenings or a combination of each. Brotizolam inhibits the hypothalamus and cerebral limbic system controlling emotion through GABA, a typical inhibitory transmitter of central nervous system. As a result, unnecessary stimulation from the autonomic nervous system and other sites is blocked, demonstrating central nervous action including hypnosis, sedation and anti-anxiety

Trimetozine (brand name Trioxazine) is a sedative agent, which has been used in the treatment of anxiety.

Bromazepam (marketed under several brand names, including Lectopam, Lexotan, Lexilium, Lexaurin, Brazepam, Rekotnil, and Lexotanil)[1] is a benzodiazepine derivative drug, patented by Roche in 1963 and developed clinically in the 1970s. It is mainly an anti-anxiety agent with similar side effects to diazepam (Valium). In addition to being used to treat anxiety or panic states, bromazepam may be used as a premedicant prior to minor surgery. Bromazepam typically comes in doses of 3 mg and 6 mg tablets.[5] Bromazepam is contraindicated and should be used with caution in women who are pregnant, the elderly, patients with a history of alcohol or other substance abuse disorders and children. Prolonged use of bromazepam causes tolerance and may lead to both physical and psychological dependence on the drug, and as a result, it is a medication which is controlled by international law. Bromazepam binds to the GABA receptor GABAA, causing a conformational change and increasing the inhibitory effects of GABA. Bromazepam is a long-acting benzodiazepine and is lipophilic and metabolized hepatically via oxidative pathways.

Opipramol (Insidon, Pramolan, Ensidon, Oprimol) is an antidepressant and anxiolytic used in Germany and other European countries. Although it is a member of the tricyclic antidepressants, opipramol's primary mechanism of action is much different in comparison, it doesn’t represent a tricyclic antidepressant drug as it does not inhibit the neuronal uptake of norepinephrine and/or serotonin. Opipramol also acts as a low to moderate affinity antagonist for the D2, 5-HT2, H1, H2, and muscarinic acetylcholine receptors. H1 and H2 receptor antagonism account for its antihistamine effects, and muscarinic acetylcholine receptor antagonism is responsible for its anticholinergic properties. Opipramol was developed by Schindler and Blattner in 1961. Opipramol is typically used in the treatment of generalized anxiety disorder (GAD) and somatoform disorders. Its anxiolysis becomes prominent after only one to two weeks of chronic administration. Upon first commencing treatment, opipramol is rather sedating in nature due to its antihistamine properties, but this effect becomes less prominent with time. The therapy with Opipramol indicates an additional therapy with neuroleptics, hypnotics and tranquilizers (e.g. Barbiturates, Benzodiazepines). Therefore, it should be noted that some specific reactions, particularly CNS depressant effects could be intensified and an intensification of common side effects may occur. If necessary the dosage may be reduced. Co-administration with alcohol can cause stupor. MAO Inhibitors should be discontinued at least 14 days before the treatment with Opipramol. Concomitant use of Opipramol with β-blockers, antiarrhythmics (of class 1c), as well as drugs from tricyclic antidepressant group and preparations which influence the microsomal enzyme system, can lead to change in plasma concentration of these drugs. Co-administration of neuroleptics (example- haloperidol, risperidone) can increase the plasma concentration.

Pipamperone (INN, USAN, BAN), also known as Carpiperone and Floropipamide or Fluoropipamide, and as Floropipamide hydrochloride (JAN), is a typical antipsychotic of the butyrophenone family used in the treatment of schizophrenia. It is or has been marketed under brand names including Dipiperon, Dipiperal, Piperonil, Piperonyl, and Propitan. Pipamperone acts as an antagonist of the 5-HT2A, 5-HT2B, 5-HT2C D2, D3, D4, α1-adrenergic, and α2-adrenergic receptors. It shows the much higher affinity for the 5-HT2A and D4 receptors over the D2receptor (15-fold in the case of the D4 receptor, and even higher in the case of the 5-HT2A receptor), is regarded as "highly selective" for the former two sites at low doses. Pipamperone has low and likely insignificant affinity for the H1 and mACh receptors, as well as for other serotonin and dopamine receptors. Low-dose pipamperone (5 mg twice daily) has been found to accelerate and enhance the antidepressant effect of citalopram. Pipamperone is approved in some European countries. At its usually recommended antipsychotic dose (120–360 mg/d), it has relatively weak neuroleptic activity because it is only moderately effective as a dopamine D2-receptor antagonist, even at high doses.
