As we collect evidence provided to us by our ever-expanding group, we’ve come up with a few good remedies. Anxiolytic drugs are known to “relieve anxiety”.[1] Many of us suffer from anxiety ranging from slight to severe impairment. It is wise to note that some drugs, such as Bacopa, have enhanced efficacy after chronic administration.[2] Others, such as Tenoten, are applied sublingually and can be used to treat acute anxiety.[3] Any of the information here is not to be used or substituted for medical advice.
Bacopa
Bacopa monnieri (also known as Brahmi) is one of the most important herbs in Ayurvedic medicine. It has been used for centuries as a mental tonic originating in India.
Bacopa has been shown in studies to relieve anxiety, improve cognition, and enhance memory formation.[4] [5] In a rat study, Bacopa increased the levels of serotonin and enhanced the gene expression of serotonin transporters[6]. Studies have shown a relationship between high levels of serotonin and positive mood.[7] [8]
Bacopa also appears to have an adaptogenic effect by reducing the biochemical effects of stress.[9]
To fully appreciate the positive effects of Bacopa, it needs to be taken consistently. Studies have shown more improvement as time passes. [10]
Ashwagandha
Withania somnifera, commonly known as Ashwagandha, is a popular herb used in Ayurvedic medicine. In Sanskrit, Ashwagandha means “the smell of a horse”, because of its unmistakable smell. It is also believed to give vitality and the “strength of a stallion”.
Ashwagandha is believed to act as a neuroprotector, anxiolytic, anti-inflammatory, thyroid-booster, and libido enhancer.
Ashwagandha activates GABA-A receptors, the mechanism of action responsible for its anxiolytic and sleep-inducing effects.[11]
It has been shown to be as effective as fluoxetine for obsessive-compulsive disorder (OCD) in a mice study.[12]
L-Theanine
L-Theanine is a natural amino acid contained in green tea. Most store-bought teas contain minimal amounts of L-Theanine, however, concentrations are greater in teas such as matcha, gyokuro, and kabusecha.
L-Theanine is structurally similar the neurotransmitters glutamate and GABA.[13] L-Theanine is also a neuroprotective agent[14] which increases the amounts of serotonin, dopamine, and GABA in various areas of the brain.[15] It’s commonly used with stimulants, — like caffeine or amphetamines —, to reduce side effects, but it is also effective by itself.
Inositol
Inositol is a sugar involved in cellular signaling and as a component of cell membranes. There are nine different inositol molecules. The most abundant of these being myo-inositol.
Inositol was once considered a B vitamin (formerly Vitamin B8). It was later found to be producible by the human body, disproving it as an essential nutrient. It is naturally found in small quantities in milk products, fruits, and vegetables.
Research shows high dose Inositol supplementation (18 g) was as effective as fluvoxamine (150 mg) in decreasing the number of panic attacks[16] and reducing the symptoms of obsessive-compulsive disorder (OCD). [17]
Phenibut
Phenibut is a gamma-aminobutyric acid (GABA) derivative.
GABA is the major inhibitory neurotransmitter in the brain. The mechanism of action of conventional anxiolytics, hypnotics, and sedatives (such as benzodiazepines, barbiturates, and alcohol) increase GABA levels. This is what gives them anti-anxiety, sleep-inducing, tranquilizing, and anticonvulsive effects.
Phenibut was developed in the Soviet Union in the 1960s as a non-sedative alternative to benzodiazepines. Phenibut is part of the Russian cosmonaut medical kit as a treatment for stress.
Phenibut activates GABA-B receptors[18] and boosts dopamine levels.[19]
Picamilon
Picamilon is another Russian nootropic made by combining niacin (vitamin B3) and GABA. This allows Picamilon to cross the blood–brain barrier[20] and have anxiolytic and vasodilating[21] effects.
It is used in Russia as a treatment for anxiety, depression[22], alcoholism[23], and brain damage.[24]
Aniracetam
Aniracetam (known as Ampamet in Europe) is a compound of Racetam family. It is a fat-soluble derivative of Piracetam.
Aniracetam modulates AMPA receptors. AMPA is one of the main three excitatory neurotransmitters (the other two being NMDA and kainate receptors). Compounds that act on AMPA receptors are called AMPAkines.
AMPAkines are substances which exhibit neuroprotective and cognition enhancing effects[25]. Some of these have been investigated as treatment for Alzheimer’s disease and other neurodegenerative conditions[26]. Aniracetam is also a potential anxiolytic[27] and antidepressant.[28] Anecdotal evidence states that Aniracetam is effective in some individuals, while others are non-responders.
Coluracetam
Coluracetam is a relatively new Japanese nootropic drug with little clinical backing. Unlike Piracetam, Coluracetam directly affects High Affinity Choline Uptake.[29] It was shelved after failing to demonstrate efficacy for Alzheimer’s.
Phase IIa clinical trials have demonstrated efficacy for comorbid MDD with GAD (Generalized Anxiety Disorder).
Anecdotal reports state Coluracetam is responsible for a sensation of “HD Vision” as well as lowered anxiety.
Fasoracetam
Fasoracetam, also referred to as NS-105, is a novel cognitive enhancer. Fasoracetam is a high-affinity choline reuptake inhibitor, similar to Coluracetam.[30] Many refer to this particular mechanism of action as “HD vision”.
Fasoracetam can act as a sustainable anxiolytic since long-term administration upregulates GABA-B receptors.[31] Anecdotal reports have noted both acute and chronic anxiolytic effects.
Treatment of ADHD, by NS-105, is mediated through modulation of mGluR glutamate receptors.[32] In other words, those suffering from ADHD and/or anxiety may benefit from Fasoracetam’s purported effects.
Tianeptine
Tianeptine is a tricyclic antidepressant (TCA) developed in France circa 1960. Tianeptine embodies a unique mechanism of action, unlike other TCAs.
Tianeptine was originally believed to be a Serotonin Reuptake Enhancer. Recent research suggests its antidepressant effect is due to the activation of μ-opioid and δ-opioid receptors[33] as well as modulation of AMPA and NMDA receptors.[34]
Tianeptine efficacy is comparable to fluoxetine, amitriptyline, and imipramine (with significantly fewer side effects).[35]
Tenoten
Tenoten is a simultaneous nootropic and anxiolytic with novel properties. Unlike GABA agonists, Tenoten treats anxiety “based on antibodies to the brain-specific protein S-100B”.[36]
“Testing at the Russian Institute of Molecular Biology and Biophysics indicate Tenoten was as clinically effective as amitryptiline (Elavil), sertraline (Zoloft), and phenazepam (a benzodiazepine) for the reduction of anxiety but without sedation. It further recommended Tenoten for patients with moderate cognitive impairment”.[37]
“[Tenoten] demonstrated considerable improvement of the control over brain frontal compartment effector functions”.[38]
In a small trial group of 50 children, Tenoten showed efficacy for the treatment of ADHD symptoms.[39]
Selank
Selank, is an analog of the endogenous peptide tuftsin. Since tuftsin has innate immunomodulatory capabilities, Selank is also able to regulate T cell cytokines.[40] In this way, Selank can be seen as having immunomodulatory properties.
Unlike common anxiolytics, Selank does not cause sedation or cognitive impairment. It is non-habit forming and does not cause withdrawal symptoms.
Selank modulates monoamine transmitters[41] and catalyzes the metabolism of serotonin.[42] Selank causes rapid elevation of BDNF, solidifying its place as a cognitive enhancer.[43]
Although Selank’s mechanism of action is largely misunderstood, evidence suggests it lowers levels of tau(1/2) leu-enkephalin.[44]
Afobazole
Afobazole (also known by its scientific name Fabomotizole) is a Russian anxiolytic drug which does not possess sedative properties unlike most anxiolytics. Afobazole, similar to Fasoracetam, upregulates GABA receptors.[45] Afobazole restores GABA to healthy levels following ischemia.[46] This is widely regarded to be Afobazoles main anxiolytic mechanism of action.
Fabomotizole also induces BDNF and NGF release, agonizes MT3 receptors, and reversibly inhibits MAO-A [47] [48] [49] [50] [51]. Since Afobazole directly effects BDNF and NGF, it is also classified as a nootropic. Caution should be taken when combining Afobazole with other MAO inhibiting substances. Afobazole may also have an antidepressant effect.
Kava
Kava is a GABAergic drug which affects the GABA-A receptor in several ways. Kava exhibits reverse tolerance. It is a less-harmful alternative to common GABA-A benzodiazepine receptor agonists. The alkaloids chiefly responsible for Kava’s mechanism of action are called kavalactones.[52] It is becoming apparent that although Kava is confirmed to modulate GABA-A receptors, it may do so in a different method than direct agonism.[53] It appears Kava potentiates GABA-A through poorly understood means.[54] GABA-A receptor density increased following administration of Kava, suggesting both upregulating and sensitizing properties.[55]
A common concern for Kava usage lies in its purported hepatotoxicity. Hepatotoxicity of Kava is a direct result of the extract or plant matter obtained, suggesting quality is paramount to avoiding liver damage. “Risk factors included overdose, prolonged treatment, and comedication with synthetic drugs and dietary supplements”.[56] Indigenous tribes have been using Kava for centuries, with minimal consequences. One can assume toxicity is directly affected by the quality of the plant used.
Most, but not all, of clinical studies, have demonstrated Kava’s efficacy as an anxiolytic. Standardized extract demonstrated the highest efficacy versus placebo. 1 week of chronic administration may be necessary to feel its effects. Evidence suggests Kava may aid in the treatment of insomnia and sleeplessness.[57]
