Definitions
- the invention belongs to the technical field of medicinal chemical synthesis, relates to an agomdatine crystal and a preparation thereof, and an application of agomelatine crystal as an active ingredient in preparing a medicine for treating depression.
- depression is the main type of mood disorder, a syndrome characterized by significant and persistent low mood. Mainly manifested as depression, low interest, pessimism, slow thinking, lack of initiative, self-blame, poor diet, poor sleep, worry about suffering from various diseases, feeling multiple discomforts in the body, serious suicidal thoughts and behaviors .
- the treatment of depression mainly relies on western medicine. Although it has certain effects, it has different degrees of side effects and dependence.
- Agomelatine is the first agonist of melatonin 1, 2 (MT1 MT2 ) receptor, and an antagonist of serotonin 2c ( 5HT2c ) receptor. .
- Antidepressants are effective in reducing depression by increasing the concentration of serotonin, but they also have many side effects, such as weight changes, sexual dysfunction, and withdrawal syndrome.
- agomelatine directly binds to the serotonin 2c (5HT2c) receptor of the synaptic membrane, thereby exerting its antidepressant effect without increasing the serotonin concentration in the synaptic cleft.
- This unique mechanism of action allows agomelatine to quickly and effectively exert its antidepressant effects while minimizing the side effects of the drug.
- the MT1 MT2 receptor is densely distributed in the human suprachiasmatic nucleus, which mainly controls the human sleep rhythm.
- Agomelatine is an agonist of the MT1 MT2 receptor.
- the quality of sleep has a causal relationship with the outcome of depression. According to reports, 80% of people with depression have problems with sleep disorders to varying degrees. The improvement in sleep quality directly contributes to the improvement of the overall clinical status of patients with depression.
- Agomelatine has an ideal Long-term and short-term efficacy, the drug works quickly, and significantly reduces the recurrence and re-ignition rate of depressed patients; safety is significantly better than SSRI, SNRI drugs, while improving the core symptoms of depression, significantly improve the patient's sleep quality , improved the morning state of awakening. There is no doubt that the advent of Agomelatine has opened up new options for doctors and patients in the treatment of depression.
