Mebicar (or tetramethylglycoluril) is an anxiolytic medication produced by Latvian pharmaceutical company Olainfarm and sold in Latvia and Russia under the brand name Adaptol. [2]

Contents

Mebicar chemical structure is similar to metabolites in human body and it doesn't interract with acids, alkali, oxidants and reducing agents. It affects all major neurotransmitter systems.

Mebicar has an effect on the structure of limbic-reticular activity, particularly on hypothalamus emotional zone, as well as on all 4 basic neuromediator systems – γ aminobutyric acid (GABA), choline, serotonin and adrenergic activity. Mebicar decreases the brain noradrenaline level, exerts no effect on the dopaminergic systems, increases the brain serotonin level, and does not elicit cholinolytic action. [3]

Mebicar purportedly has anti-anxiety (anxiolytic) properties. [3] [4] [5] [6] [7] It is also used to aid smoking cessation. [2] In addition, mebicar may be useful in the treatment of ADHD symptoms. [8] In contrast with typical anxiolytic medications such as benzodiazepines, mebicar is non-habit forming, non-sedating and does not impair motor function. [4] [2]

It can be prepared by condensation of dimethyl urea (which can be made by n, n methylating urea using paraformaldehyde+oxalic acid dihydrate) with glyoxal. One recent publication described an elegant variation in which the two reactants are combined in an aqueous solution with phosphoric anhydride as the catalyst; the reaction takes place at room temperature, is fast, with essentially quantitative yield, and the procedure is easy and cost efficient because the product precipitates as it is formed, and after removal of the solids by filtration, the leftover solution can be used one or more times with no additional catalyst (with a longer reaction time).[ citation needed ]

As of 2021, mebicar has not been evaluated by the U.S. medical system.

Medical uses

Mebicar is used in Latvia and Russia, as a pharmaceutical drug to treat anxiety and to prevent or reduce anxiety, unrest, fear, internal emotional tension and irritability, reduce neuroses and neurotic disorders, heartburns of non-coronary heart disease origin. These effects are not accompanied with relaxation of muscle tone and impaired coordination of movement, suppression of mental and physical activity, so the drug can be used without interruption of work or school.

Mebicar does not have a direct effect on sleep, however, it enhances the effectiveness of sleep medicines and normalizes the course of disturbed sleep. Mebicar alleviates or eliminates the manifestations of nicotine dependence that occur after smoking cessation. Mebicar does not cause mood swings or euphoria, no habituation and addiction, withdrawal syndrome has been observed.

Side effects

Possible and rare side effects may include dizziness, hypotension, indigestion, allergic reactions (itchy skin) after high doses, hypothermia, fatigue. And lowered blood pressure and / or body temperature decreased by 1-1.5°C. Blood pressure and body temperature return to normal after completion of treatment. [9]

An anxiolytic is a medication or other intervention that reduces anxiety. This effect is in contrast to anxiogenic agents which increase anxiety. Anxiolytic medications are used for the treatment of anxiety disorder and its related psychological and physical symptoms.

Dysautonomia Any disease or malfunction of the autonomic nervous system

Dysautonomia or autonomic dysfunction is a condition in which the autonomic nervous system (ANS) does not work properly. This may affect the functioning of the heart, bladder, intestines, sweat glands, pupils, and blood vessels. Dysautonomia has many causes, not all of which may be classified as neuropathic. A number of conditions can feature dysautonomia, such as Parkinson's disease, multiple system atrophy, and dementia with Lewy bodies, Ehlers-Danlos syndromes, autoimmune autonomic ganglionopathy and autonomic neuropathy, HIV/AIDS, autonomic failure, and postural orthostatic tachycardia syndrome.

Phenylpiracetam

Phenylpiracetam, is a phenylated analog of the drug piracetam. It was developed in 1983 as a medication for Soviet Cosmonauts to treat the prolonged stresses of working in space. Phenylpiracetam was created at the Russian Academy of Sciences Institute of Biomedical Problems in an effort led by psychopharmacologist Valentina Ivanovna Akhapkina. In Russia it is now available as a prescription drug. Research on animals has indicated that phenylpiracetam may have anti-amnesic, antidepressant, anticonvulsant, anxiolytic, and memory enhancement effects.

Dopaminergic Substance related to dopamine functions

Dopaminergic means "related to dopamine" (literally, "working on dopamine"), dopamine being a common neurotransmitter. Dopaminergic substances or actions increase dopamine-related activity in the brain. Dopaminergic brain pathways facilitate dopamine-related activity. For example, certain proteins such as the dopamine transporter (DAT), vesicular monoamine transporter 2 (VMAT2), and dopamine receptors can be classified as dopaminergic, and neurons that synthesize or contain dopamine and synapses with dopamine receptors in them may also be labeled as dopaminergic. Enzymes that regulate the biosynthesis or metabolism of dopamine such as aromatic L-amino acid decarboxylase or DOPA decarboxylase, monoamine oxidase (MAO), and catechol O-methyl transferase (COMT) may be referred to as dopaminergic as well. Also, any endogenous or exogenous chemical substance that acts to affect dopamine receptors or dopamine release through indirect actions (for example, on neurons that synapse onto neurons that release dopamine or express dopamine receptors) can also be said to have dopaminergic effects, two prominent examples being opioids, which enhance dopamine release indirectly in the reward pathways, and some substituted amphetamines, which enhance dopamine release directly by binding to and inhibiting VMAT2.

Tianeptine Antidepressant

Tianeptine, sold under the brand names Stablon and Coaxil among others, is an atypical antidepressant which is used mainly in the treatment of major depressive disorder, although it may also be used to treat anxiety, asthma, and irritable bowel syndrome.

Piribedil

Piribedil (trade names Pronoran, Trivastal Retard, Trastal, Trivastan, Clarium and others) is an antiparkinsonian agent and piperazine derivative which acts as a D2 and D3 receptor agonist. It also has α2-adrenergic antagonist properties.

Oneiroid syndrome (OS) is a condition involving dream-like disturbances of one's consciousness by vivid scenic hallucinations, accompanied by catatonic symptoms, delusions, or psychopathological experiences of a kaleidoscopic nature. The term is from Ancient Greek "ὄνειρος" and "εἶδος". It is a common complication of catatonic schizophrenia, although it can also be caused by other mental disorders. The dream-like experiences are vivid enough to seem real to the patient. OS is distinguished from delirium by the fact that the imaginative experiences of patients always have an internal projection. This syndrome is hardly mentioned in standard psychiatric textbooks, possibly because it is not listed in DSM.

Mesocarb is a drug that is currently being developed for Parkinson's disease.

Periciazine Chemical compound

Periciazine (INN), also known as pericyazine (BAN) or propericiazine, is a drug that belongs to the phenothiazine class of typical antipsychotics.

Fabomotizole

Fabomotizole is an anxiolytic drug launched in Russia in the early 2000s. It produces anxiolytic and neuroprotective effects without any sedative or muscle relaxant actions. Its mechanism of action remains poorly defined however, with GABAergic, NGF- and BDNF-release-promoting, MT1 receptor agonism, MT3 receptor antagonism, and sigma agonism suggested as potential mechanisms. Fabomotizole was shown to inhibit MAO-A reversibly and there might be also some involvement with serotonin receptors. Clinical trials have shown fabomotizole to be well tolerated and reasonably effective for the treatment of anxiety.

Echinopsidine

Echinopsidine (Adepren) is an antidepressant that was under development in Bulgaria for the treatment of depression. It increases serotonin, norepinephrine, and dopamine levels in the brain and is believed to act as a monoamine oxidase inhibitor (MAOI). Echinopsidine is found naturally in Echinops echinatus along with the related alkaloids echinopsine and echinozolinone.

Mepiprazole

Mepiprazole is an anxiolytic drug of the phenylpiperazine group with additional antidepressant properties that is marketed in Spain. It acts as a 5-HT2A and α1-adrenergic receptor antagonist and inhibits the reuptake and induces the release of serotonin, dopamine, and norepinephrine to varying extents, and has been described as a serotonin antagonist and reuptake inhibitor (SARI). Controlled clinical trials of mepiprazole in patients with irritable bowel syndrome (IBS) were also carried out and suggested some benefits of the drug in relieving symptoms of IBS in some patients. Similarly to other phenylpiperazines like trazodone, nefazodone, and etoperidone, mepiprazole produces mCPP as an active metabolite.
