Психотропные средства — это группа лекарственных препаратов, которые влияют на психоэмоциональное состояние, поведение, восприятие и сознание человека. Они могут вызывать изменения в настроении, восприятии, познавательных функциях, а также изменять психическую активность, такие как тревожность, депрессия, агрессия или эйфория. Эти препараты применяются в психиатрии и неврологии для лечения различных психических заболеваний, таких как депрессия, шизофрения, биполярные расстройства, тревожные расстройства и другие состояния, сопровождающиеся нарушениями психического здоровья.
Психотропные средства воздействуют на нейрохимические процессы в мозге, регулируя активность нейротрансмиттеров, таких как дофамин, серотонин, норадреналин, ГАМК и другие, которые играют ключевую роль в формировании эмоций, настроения и поведения. Это позволяет использовать их для коррекции психопатологических симптомов и улучшения качества жизни пациентов. Однако важно помнить, что использование этих препаратов требует тщательной диагностики, контроля и наблюдения, так как они могут вызывать побочные эффекты и зависимость при длительном применении.💊

Также существуют препараты, которые комбинируют оба действия, такие как ноотропы.
Фармакокинетика психотропных средств включает всасывание, проникновение через гематоэнцефалический барьер, метаболизм в печени и выведение через почки. Каждый препарат имеет свои особенности в метаболизме, что важно учитывать при назначении.
Побочные эффекты психотропных средств могут включать экстрапирамидные расстройства, седативные эффекты, метаболические нарушения, изменения настроения, а также более серьёзные реакции, такие как нейролептический малигнитет. Важно учитывать противопоказания, такие как заболевания печени и почек, беременность и лактацию, а также возможность зависимости и синдрома отмены.
Знание этих препаратов и их особенностей позволяет правильно использовать их в лечении психических расстройств при минимизации рисков и побочных эффектов, обеспечивая эффективное и безопасное лечение для пациентов. 💊📚
Psychotropic drugs are a group of medications that affect a person's psychoemotional state, behavior, perception, and consciousness. They can cause changes in mood, perception, cognitive functions, as well as alter mental activity, such as anxiety, depression, aggression, or euphoria. These drugs are used in psychiatry and neurology to treat various mental disorders, such as depression, schizophrenia, bipolar disorders, anxiety disorders, and other conditions associated with mental health disturbances.
Psychotropic drugs influence neurochemical processes in the brain by regulating the activity of neurotransmitters such as dopamine, serotonin, norepinephrine, GABA, and others, which play a key role in the formation of emotions, mood, and behavior. This allows them to be used to correct psychopathological symptoms and improve the quality of life of patients. However, it is important to remember that the use of these drugs requires careful diagnosis, control, and monitoring, as they can cause side effects and dependency with prolonged use. 💊
Mental disorders are pathological changes in mental activity that can be associated with disturbances in the neurochemical balance in the brain, genetic factors, trauma, stress, or infections.
Neurochemical disorders:
Dopamine — plays a key role in regulating mood, motivation, and emotional response. Disruptions in the dopamine system can lead to psychosis, delusions, and hallucinations, which are characteristic of schizophrenia. 💡
Serotonin — regulates emotional state, sleep, appetite, sexual behavior, and pain perception. A deficiency in serotonin is often observed in depression and anxiety disorders. 🌙
Norepinephrine — important for the stress response, arousal, and attention. A deficiency in norepinephrine can cause depression, while an excess can lead to hyperactivity and anxiety. ⚡
GABA (Gamma-Aminobutyric Acid) — the main inhibitory neurotransmitter, disruption of its activity can lead to excessive nerve cell activity, causing anxiety disorders and epilepsy. 😰
Genetic factors:
Some mental disorders have a hereditary predisposition, such as schizophrenia and bipolar disorder. Genetic mutations and anomalies can affect the functioning of neurotransmitter systems and predispose a person to the development of psychopathologies. 🌧️
Stressful and traumatic factors:
Stress — a powerful trigger for many mental disorders. Chronic stress can cause disruptions in the hypothalamic-pituitary-adrenal axis, which, in turn, affects the balance of neurotransmitters, leading to depression, anxiety disorders, and psychosis. 💊
Psychological trauma — stressful events (loss, violence, divorce, chronic illness) can cause the development of post-traumatic stress disorder (PTSD), depression, and other disorders.
Infectious and inflammatory brain diseases:
Some mental disorders may be caused by infections or inflammations, such as meningitis or encephalitis, which disrupt normal brain function and neurotransmitter systems.
Disruptions in neural connections and brain structures:
The brains of patients with mental disorders, such as schizophrenia, may show structural changes in certain areas, such as the prefrontal cortex, which is responsible for decision-making, planning, and emotional perception.
The prefrontal cortex and limbic system play an important role in regulating emotions and behavior. Their dysfunction may be associated with conditions such as depression, anxiety, and schizophrenia.
🧠 Mnemonic: "ДоСеНоГа" → Dopamine, Serotonin, Norepinephrine, GABA.
Psychotropic drugs can be classified based on their effect on the central nervous system (CNS), their impact on neurotransmitters, and their main indications.
Inhibitory agents (depressants):
These drugs have a depressant effect on the CNS, reducing the activity of neurotransmitters such as dopamine and norepinephrine.
Stimulant agents (stimulators):
These drugs increase CNS activity by raising the levels of neurotransmitters such as dopamine and norepinephrine.
Other groups:
🧠 Mnemonic: "НТС САНПГ" — Neuroleptics, Tranquilizers, Sedatives, Antidepressants, Nootropics, Psychostimulants, Hallucinogens.
Neuroleptics (Antipsychotics):
The main mechanism of action is the blockade of dopamine receptors (D2). This leads to a reduction in the activity of the dopamine system in the brain, effectively eliminating the symptoms of psychosis (delusions, hallucinations). Their primary use is for the treatment of schizophrenia and other psychoses. However, the blockade of dopamine can cause extrapyramidal side effects (e.g., parkinsonism), which limits the use of older drugs in this group.
Second-generation neuroleptics (e.g., clozapine) block both dopamine and serotonin receptors, which helps reduce side effects such as movement disorders. 🌟
Antidepressants:
Tranquilizers:
The main mechanism of action is the enhancement of GABA activity (the main inhibitory neurotransmitter), which strengthens inhibitory processes in the CNS. This reduces anxiety, improves sleep, and has a sedative effect. These drugs are commonly used for anxiety and insomnia. 😌
Psychostimulants:
Psychostimulants increase the release of dopamine and norepinephrine, which improves attention, motivation, and alertness. This helps increase work capacity and activity. For example, caffeine increases the release of these neurotransmitters, stimulating the nervous system. ⚡
Absorption — Psychotropic drugs are generally well absorbed when taken orally (per os), especially when they are in the form of tablets or capsules. 💊
Absorption can depend on the physicochemical properties of the drug (solubility, molecule size, presence of food) and the condition of the patient's digestive tract.
Penetration through barriers — All psychotropic drugs can pass through the blood-brain barrier (BBB), which is necessary for their action on the brain.
Drugs that pass through the BBB can affect the central nervous system, which is important for their therapeutic effect, but it can also lead to side effects.
Metabolism — Biotransformation occurs in the liver with the help of cytochrome P450 enzymes. These enzymes are responsible for the metabolism of many psychotropic drugs. 🧪
Inhibitors or inducers of these enzymes can alter the metabolism of other drugs, which requires caution when prescribing them together with other medications.
For example, drugs like fluoxetine (an antidepressant) are metabolized with the involvement of cytochrome P450, which should be considered when prescribing drugs with the same metabolic pathway.
Excretion — Psychotropic drugs are predominantly excreted by the kidneys in the form of metabolites. 🚽
It is important to consider that in cases of impaired kidney function (e.g., in patients with chronic renal failure), the rate of drug excretion may change, requiring dose adjustments.
Neuroleptics — Reduction of dopamine activity in the brain leads to the alleviation of symptoms of psychosis. 🔻
Antidepressants — Increased concentrations of serotonin and norepinephrine in the synapses exert an antidepressant effect.
Tranquilizers — Enhancement of inhibitory processes in the CNS through the activation of GABA receptors reduces anxiety levels.
Psychostimulants — Increase CNS activity, enhancing attention, motivation, and alertness. ⚡

General side effects of all psychotropic drugs:
🧠 Mnemonic: "ТЕКСТГ" → Travel, Extrapyramidal, Coordination, Sleep, Tachycardia, Giddiness
Psychotropic drugs are medications that affect a person's psychoemotional state, behavior, and perception. They are used to treat mental illnesses such as depression, schizophrenia, anxiety disorders, and bipolar disorder. These drugs influence neurochemical processes in the brain by regulating the activity of neurotransmitters such as dopamine, serotonin, norepinephrine, and GABA.
The drugs are classified based on their effects on the central nervous system, the type of neurotransmitters, and their indications. Depressant agents, such as neuroleptics and tranquilizers, reduce CNS activity, while stimulating drugs, such as antidepressants and psychostimulants, enhance it. There are also drugs that combine both effects, such as nootropics.
The pharmacokinetics of psychotropic drugs includes absorption, penetration through the blood-brain barrier, metabolism in the liver, and excretion through the kidneys. Each drug has its own metabolic characteristics, which are important to consider when prescribing.
The side effects of psychotropic drugs can include extrapyramidal disorders, sedative effects, metabolic disturbances, mood changes, and more severe reactions such as neuroleptic malignant syndrome. It is important to consider contraindications, such as liver and kidney diseases, pregnancy and lactation, as well as the possibility of dependence and withdrawal syndrome.
Knowledge of these drugs and their characteristics allows for their proper use in treating mental disorders while minimizing risks and side effects, ensuring effective and safe treatment for patients. 💊📚
