Valdoxan, 25 mg, film-coated tablets, 14 pcs.

Heavy physical and emotional stress associated with the fast pace of life, stress and a difficult family situation cause the development of prolonged depression.

Antidepressants help cope with the disease. One of these is Valdoxan .

Pharmacodynamics and pharmacokinetics

Agomelatine is a substance with an antidepressant effect aimed at validated models of depression and some other abnormalities in the activity of the nervous system. At the same time, drugs created on its basis do not have a strong negative effect on the activity of other body systems.

Taking agomelatine helps normalize sleep structure, lower body temperature and improve the release of melatonin . The drug can be used to treat nervous system disorders of varying degrees of complexity, therefore both short-term and long-term therapy is allowed.

As a result of internal administration, absorption occurs quite quickly and almost completely. The maximum concentration in plasma is achieved 1-2 hours after administration of the drug. When distributed within the body, the substance is almost completely bound to plasma proteins, regardless of the concentration of the drug, the age of the patient, or the presence of renal impairment. A fairly rapid elimination of the drug from the body was noted, mainly in the form of metabolites through the kidneys. A small part of the unchanged substance is also excreted in the urine.

pharmachologic effect

Valdoxan (an analogue of agomelatine) counteracts the functioning of melatonin MT1 and MT2 receptors and serotonin 5-HT2c receptors.

As a result of scientific research, the activity of Valdoxan in the treatment of:

• Models of depression that meet established requirements, such as acquired helplessness, despair, moderate chronic stress;
• Modeled depression caused by disruption of cyclical fluctuations in the intensity of biological processes associated with the change of day and night (circadian rhythms);
• In situations of experimentally induced anxiety and stress.

It has been proven that Valdoxan has no effect on the uptake of monoamines and does not affect the functioning of α-, β-adrenergic receptors, histamine receptors, cholinergic receptors, dopamine and benzodiazepine receptors.

Valdoxan enhances the release of norepinephrine and dopamine, especially in the prefrontal cortex, and does not affect the concentration of serotonin outside cells.

Research results have shown that by stimulating melatonin receptors, Valdoxan promotes the release of melatonin. This restores circadian rhythms, normalizes sleep patterns and lowers body temperature, slowing down physiological processes.

Even short-term use of Valdoxan (6-8 weeks) 25-50 mg per day is effective for major depressive episodes, more severe forms of depression, with initially high levels of anxiety and with a combination of depressive and anxiety disorders. Research confirms the long-term supportive antidepressant and anti-relapse effects of Valdoxan.

Daily intake of 25 mg of Valdoxan in patients with depression does not affect memory and attention. Promotes rapid falling asleep and improves sleep quality (the duration of the long-term sleep phase increases, the number and duration of REM sleep phases do not change). At night, the heart rate decreases, and during the day there is no lethargy. There is a tendency to reduce sexual dysfunction, and a positive effect on sexual arousal and orgasm is noted.

During the daytime, the heart rate, pulse and blood pressure of patients do not change from taking Valdoxan, and body weight is stable.

Withdrawal syndrome does not occur even if the medication is abruptly stopped; Valdoxan does not cause addiction syndrome.

Side effects

As a rule, the manifestation of side effects is observed at the very beginning of treatment. Patients are especially often concerned about: nausea, dizziness, drowsiness, headache, insomnia, fatigue, anxiety, sweating, and so on. All these symptoms are not severe and usually do not require additional treatment. Gradually their manifestation decreases and completely disappears.

If necessary, carry out symptomatic treatment and monitor the general condition of the patient.

Indications for use

Valdoxan is a modern and safe antidepressant that is indicated for use in the complex treatment of episodes of deep depression with a prolonged feeling of psycho-emotional depression, apathy, and lack of interest in the world around us and the events occurring in it.

Minor changes in the liver occur in most patients in the first month of therapy, but then the situation often stabilizes. Upon completion of the course of treatment, all indicators return to normal without additional use of pharmacological agents.

• In clinical trials, less than 300 cases of pregnant women were considered, so it is too early to draw conclusions on the relativity of the effect of the active substance on the body of the expectant mother based on scant information. Animal studies have not shown direct or indirect threats to the female and fetus.
