Selank spray is an artificially synthesized heptapeptide with an amino acid sequence of Thr Lys Pro Arg Pro Gly Pro. It is usually made through a specific spray device after being dissolved in an appropriate solvent. The spray is easy to use and can directly act on the nasal mucosa and enter the blood circulation through nasal absorption, thus playing a pharmacological role. It was initially developed as a synthetic analogue of pro phagocytic peptides. With the deepening of research, it has been found to have various pharmacological activities, such as anti anxiety, improving cognitive function, regulating immunity, etc. In order to make it more convenient to use, researchers made it into a spray form, so that it can be administered through the nasal cavity to improve the bioavailability of the drug and the compliance of patients.

Treatment of anxiety disorders
For the crowd:
It is suitable for patients with various types of anxiety disorders, including generalized anxiety disorder, social anxiety disorder, panic disorder, etc. For patients who are intolerant or ineffective with traditional anti anxiety drugs, It may be an effective alternative treatment option.
Treatment Plan:
When using Selank spray to treat anxiety disorders, it is usually necessary to develop personalized treatment plans based on the patient's specific situation. It is generally recommended to start with 1-2 sprays per day, and gradually adjust the dosage based on the patient's response. The treatment cycle is generally several weeks to several months, depending on the severity of the patient's condition and the effectiveness of the treatment.
Improvement of cognitive impairment
Alzheimer's disease:
In the early stage of Alzheimer's disese, It may help improve the cognitive function of patients and delay the progress of the disese. It can improve patients' memory, attention, and thinking abilities, and enhance their quality of life. However, at present, there are relatively few studies on It in the treatment of Alzheimer's disese, and further clinical trials are needed to verify its efficacy and safety.
mild cognitive impairment:
For patients with mild cognitive impairment, It can be used as an auxiliary treatment. It can promote neural repair and regeneration in the brain, improve cognitive function, and prevent further deterioration of the condition.
Treatment of stress-related diseases
Post traumatic stress disorder (PTSD):
PTSD is a mental disorder caused by experiencing traumatic events, in which patients often experience symptoms such as anxiety, fear, and recalling traumatic scenes. It can reduce the stress reaction of patients and improve their symptoms by regulating the neurotransmitter system and immune system. In some preliminary studies targeting PTSD patients, It has shown certain therapeutic effects.
chronic fatigue syndrome:
Patients with chronic fatigue syndrome often have emotional problems such as anxiety and depression, as well as cognitive dysfunction. It can improve the emotional state and cognitive function of patients, reduce fatigue, and improve the quality of life of patients.
Mechanism of Action
It plays an anti anxiety role by regulating the neurotransmitter system, such as γ - aminobutyric acid (GABA) system and serotonin system. GABA is an important inhibitory neurotransmitter in the central nervous system, which can suppress the excitability of neurons and alleviate anxiety symptoms. Selan can increase the activity of GABA receptors and enhance the inhibitory effect of GABA. Meanwhile, Selan can also regulate the levels of serotonin, a neurotransmitter closely related to emotion regulation.
Imbalance in its levels may lead to emotional disorders such as anxiety.
Clinical study
In many clinical studies, spray has been proved to have significant anti anxiety effect. For example, in a clinical trial for patients with anxiety disorder, the anxiety symptoms of patients have been significantly improved after the use of sprays, such as tension, anxiety, fear and other emotions have been reduced, and the quality of sleep has also been improved.
Improve cognitive function
The impact on learning and memory
Can improve learning and memory abilities. It can enhance the brain's information processing and storage capabilities by promoting the growth of neurons and synaptic plasticity. In animal experiments, rats showed a significant improvement in their learning and memory performance in maze experiments, indicating an improvement in their cognitive function.
The impact on attention and reaction speed
Selan can also improve attention and reaction speed. It can regulate the neural activity of the brain, enhance the efficiency of information transmission between neurons, thereby making individuals more focused on tasks and more responsive. In some cognitive function tests, individuals who use Selank spray perform well in terms of attention and reaction speed.
Immune regulatory effect
Regulating immune cell activity
It can regulate the activity of immune cells, such as enhancing the phagocytic function of macrophages and the proliferation ability of lymphocytes. Macrophages are important cells in the immune system that can engulf and eliminate pathogens and foreign substances. It can promote the activation of macrophages, enhance their phagocytic ability, and thus strengthen the body's immune defense function. Lymphocytes participate in the specific immune response of the body, promoting their proliferation and differentiation, and enhancing the body's immune response ability.
Regulating cytokine levels
Cytokines are a class of small molecule proteins secreted by immune cells that play an important role in immune regulation. It can regulate the levels of cytokines, such as increasing the secretion of anti-inflammatory cytokines and reducing the secretion of pro-inflammatory cytokines, thereby maintaining the balance of the immune system. This immune regulatory effect helps alleviate inflammatory reactions, prevent and treat some immune related diseses.
Stable regulation of GABAergic system (eliminating the interference of anxiety on cognition)
Selank does not directly bind to the benzodiazepine site to forcibly activate GABA receptors, but acts as an indirect allosteric modulator to upregulate the gene expression of GABA-A receptor α 2 and γ 2 subunits in the hippocampus and amygdala, enhancing the efficiency of endogenous GABA inhibitory signals in the brain; In simple terms, sedatives are used to induce sedation, while Selank repairs the natural calm regulation ability of the brain.
When there is excessive anxiety, the amygdala becomes overly excited and seizes the brain's computing power, blocking hippocampal memory encoding; Selank reduces background anxiety arousal, clears cognitive computing power occupation, improves thinking clarity and attention synchronously, and completely avoids the typical side effects of benzodiazepines such as drug brain, memory fragmentation, and delayed response.

Comparison between Selank spray and Other Similar Products
Comparison with traditional anti anxiety drugs
Differences in mechanism of action
Traditional anti anxiety drugs, such as benzodiazepines, mainly exert their anti anxiety effects by enhancing the inhibitory effect of GABA, but long-term use may lead to adverse reactions such as dependence and tolerance. And not only can it exert its effects by regulating the GABA system, but it can also regulate the serotonin system and immune system, with a more complex and comprehensive mechanism of action.
Safety and tolerability
High safety, relatively few adverse reactions, and generally no dependence or tolerance. Traditional anti anxiety drugs may cause adverse reactions such as dizziness, drowsiness, and fatigue, and long-term use may also affect cognitive function and motor coordination.
Comparison with other nasal administration products
Differences in ingredients and efficacy
At present, there are some other nasal drug delivery products on the market, such as nasal spray, nasal gel, etc., but their ingredients and efficacy are different. For example, some nasal sprays are mainly used to relieve nasal congestion, runny nose and other symptoms, while Selan is mainly used to regulate the nervous system and immune system, improve anxiety, cognitive and other functions.
User's experience
The use experience is relatively good. The spray is delicate and easy to absorb, and will not bring obvious discomfort to patients. Some nasal medication products may cause inconvenience or discomfort to patients due to their thick texture or strong irritation.
FAQ
1. What is the core mechanism that distinguishes it from conventional anti-anxiety medications?
Selank is a synthetic heptapeptide. Its mechanism of action does not directly target the receptors of classic neurotransmitters such as GABA or serotonin. Instead, it regulates the metabolism of natural "calming agents" in the brain (such as enkephalin and galapine), and affects the expression of neurotrophic factors (BDNF), thereby more "originally" regulating emotions and stress responses. The risk of addiction and sedative side effects is relatively low.
2. What is the unique neuroscientific significance of nasal spray formulations?
Intranasal administration enables peptide substances to pass through the olfactory nerve pathway, partially bypassing the blood-brain barrier, and directly or more rapidly entering the central nervous system. This administration route aims to mimic the local delivery mode of peptides in the brain and may offer a faster onset pattern and unique target sites compared to oral or injection administration.
3. What is the current biggest controversy and unknown area?
Although it is a prescription drug in Russia, its clinical data are mainly presented in Russian literature and lack the reproducibility that has been widely reviewed by international peers. The precise molecular targets, the impact of long-term use on neural plasticity, and whether the efficacy is significantly better than that of a placebo, remain core issues that the international neuroscience community is cautiously observing and awaits verification.
