Meptazinol is a unique opioid analgesic. Binding studies suggest a relative selectivity for mu-1 opioid receptor sites. Meptid is indicated for the treatment of moderate to severe pain, including post-operative pain, obstetric pain and the pain of renal colic. The most commonly reported adverse reactions after treatment with meptazinol are nausea, vomiting, dizziness, diarrhoea and increased sweating, constipation, abdominal pain, rash, vertigo, headache, drowsiness, somnolence and dyspepsia.

Ipidacrine (Neiromidin) is a drug first synthesized by the National Research Center for Biologically Active Compounds in the Russian Federation. Neuromidin has a direct stimulating effect on the conduct of the pulse along the nerve fibers, interneuronal and neuromuscular synapses of the CNS and peripheral nervous system. Pharmacological action neuromidin is based on a combination of two mechanisms of action: blockade of potassium channels of the membrane of neurons and muscle cells; reversible inhibition of cholinesterase in synapses. Neuromidin enhances the effect on smooth muscle acetylcholine not only, but epinephrine, serotonin, histamine and oxytocin. It has the following pharmacological effects: - Improve and stimulate impulse conduction in the nervous system and neuromuscular transmission; - Enhances contractility of smooth muscle organs under the influence of acetylcholine agonists, adrenaline, serotonin, histamine and oxytocin receptors, with the exception of potassium chloride; - Improves memory, slows progressive course of dementia. In preclinical studies Neuromidin is not teratogenic, embryotoxic, mutagenic, carcinogenic and immunotoxic action, had no effect on the endocrine system

Clotiazepam is a compound of the benzodiazepine class. The drug was developed in Japan and approved for the treatment of insomnia, anxiety and before anesthesia. Clotiazepam was marketed worlwide under different names, however, currently it is available only in South America under the name Neuroval and presumably in Japan. Clotiazepam exerts its action by binding and activating GABA-A receptors.

Butanilicaine (Hostacain) is a local anesthetic. It uses may associate with a risk of allergy. Butanilicaine has a vasodilator effect.

Tofisopam (marketed under brand names Emandaxin and Grandaxin) is a 2,3-benzodiazepine derivative that is marketed in several European countries as the anxiolytic drug. Tofisopam does not bind to the benzodiazepine binding site of the gamma-aminobutyric acid receptor. One study has shown that tofisopam acts as an isoenzyme-selective inhibitor of phosphodiesterases (PDEs) with the highest affinity to PDE-4A1 followed by PDE-10A1, PDE-3, and PDE-2A3. Like other benzodiazepines, tofisopam possesses anxiolytic properties but unlike other benzodiazepines, it does not have anticonvulsant, sedative, skeletal muscle relaxant, motor skill-impairing or amnestic properties. While it may not be an anticonvulsant in and of itself, it has been shown to enhance the anticonvulsant action of classical 1,4-benzodiazepines such as diazepam (but not sodium valproate, carbamazepine, phenobarbital, or phenytoin). Tofisopam is not approved for sale in the United States or Canada. However, Vela Pharmaceuticals of New Jersey is developing the D-enantiomer (dextofisopam) as a treatment for irritable bowel syndrome, with moderate efficacy demonstrated in clinical trials so far.

Vinpocetine is a synthetic derivative of the vinca alkaloid vincamine. Vinpocetine was first isolated from the plant in 1975 by the Hungarian chemist Csaba Szántay. The mass production of the synthetic compound was started in 1978 by the Hungarian pharmaceutical company Richter Gedeon. Vinpocetine has been reported to have cerebral blood-flow enhancing and neuroprotective effects, and has been used as a drug in Eastern Europe for the treatment of cerebrovascular disorders and age-related memory impairment. Vinpocetine acts as a phosphodiesterase (PDE) type-1 inhibitor in isolated rabbit aorta, Independent of vinpocetine's action on PDE, vinpocetine inhibits IKK preventing IκB degradation and the following translocation of NF-κB to the cell nucleus. Increases in neuronal levels of DOPAC, a metabolic breakdown product of dopamine, have been shown to occur in striatal isolated nerve endings as a result of exposure to vinpocetine. Such an effect is consistent with the biogenic pharmacology of reserpine, a structural relative of vinpocetine. However, this effect tends to be reversible upon cessation of vinpocetine administration, with full remission typically occurring within 3–4 weeks. Vinpocetine is generally well-tolerated in humans. No serious side effects have thus far been noted in clinical trials although none of these trials were long-term. Some users have reported headaches, especially at doses above 15 milligrams per day, as well as occasional upset stomach. The safety of vinpocetine in pregnant women has not been evaluated. Vinpocetine is not FDA approved in the United States for therapeutic use. The U.S. Food & Drug Administration (FDA) has ruled that vinpocetine, due to its synthetic nature and proposed therapeutic uses, was ineligible to be marketed as dietary supplement under the Federal Food, Drug, and Cosmetic Act (FDCA).

Imipraminoxide (brand names Imiprex, Elepsin) is a tricyclic antidepressant and imipramine metabolite that was used in Europe for the treatment of depression. In comparison with the imipramine, Imipraminoxide efficacy was identical to imipramine. However, in clinical trials, imipraminoxide was found to have a faster onset of action, and fewer and less marked side effects, including diminished orthostatic hypotension and anticholinergic effects like dry mouth, sweating, dizziness, and fatigue. Imipraminoxide's pharmacology has not been well elucidated, but based on its very close relationship with imipramine, it likely acts as a serotonin and norepinephrine reuptake inhibitor and serotonin, adrenaline, histamine, and muscarinic acetylcholine receptor antagonist, though with weaker antiadrenergic and anticholinergic actions

Fenozolone is a psychostimulant drug. Upon administration, it exhibits an amphetamine-like effect and increases transmission of all monoamines. Its action depends on noradrenergic, dopaminergic and serotoninergic systems. The drug was used medically as a psychostimulant and antidepressant and is known under tradename Ordinator.

Zotepine is a potent antipsychotic and antidepressive drug, which was developed in Japan and used in many countries for the treatment of schizophrenia. Zotepine has high affinity to D2, 5-HT2A, 5-HT2C, 5-HT6, 5-HT7, alpha1A, H1, and D1 receptors at therapeutically relevant concentrations and has similar affinities to 5-HT1A, alpha2A, and M1 receptors at high concentrations. In human zotepine is metabolized to a major metabolite, norzotepine, which has profile similar to that of zotepine for important neurotransmitter receptors known to be responsible for zotepine antipsychotic activity.The drug is still available in Asia.

Melperone is an antipsychotic drug which is used in Europe for the treatment of sleep disorders, agitation and confusion states. The exact mechanism of melperone action is unknown.
