What is Prozac?
Fluoxetine belongs to the group of antidepressants. It is produced by a Russian pharmaceutical company in contrast to its foreign counterpart – Prozac. The latter is the brainchild of the British pharmaceutical Corporation. Therefore, it costs an order of magnitude more expensive, and its effectiveness is comparable to the domestic drug.
How does Fluoxetine work?
Fluoxetine (Prozac) blocks the reverse flow of serotonin to neuronal synapses (places where nerve cells connect). As a result, the content of this mediator (a substance involved in the transmission of nerve impulses) in the connective elements increases significantly, so for a long time, it manages to affect the postsynaptic regions, causing characteristic changes. This is manifested by:
- Stimulating effect on the nervous system;
- Improved mood;
- Activation of mental processes;
- Suppression of anxiety and anxiety;
- Reduced appetite, ultimately leading to weight loss.
In addition to inhibiting serotonin uptake in the nervous tissue, Fluoxetine similarly affects platelets, reducing their aggregation (bonding) ability. This positive effect helps prevent thrombosis in patients at risk. But as the main therapeutic effect, this property is not used, it is a "pleasant" addition to antipsychotic effects.
An important advantage of this antidepressant is the lack of sedation. Therefore, Fluoxetine (Prozac) can be used by people engaged in precision work that requires care:
- Aviation industry, etc.
Prozac is a selective serotonin reuptake inhibitor, belongs to the group of third-generation antidepressants, and is used for the treatment of depressive, anxiety, and panic disorders (in the complex therapy). The pharmacological effect of the drug is based on an increase in the concentration of serotonin – the "happiness hormone" in the brain, which increases its effect on the nervous system. Prozac has a strong antidepressant effect and reduces anxiety, nervous tension, and fear.
The structural formula of Fluoxetine
It also treats dysphoria – a very low mood, which is characterized by strong irritability and hostility to others, sometimes bordering on aggression. Also, the medication does not negatively affect the heart, does not have a sedative effect, and does not cause an excessive decrease in blood pressure when taking an upright position.
It is well absorbed by the body. The optimal concentration of the drug in the blood plasma is reached at 2-3 weeks of administration. It is almost completely excreted by the kidneys. It is also excreted in breast milk in an amount of up to 25% of the total concentration in the blood. The therapeutic effect of Prozac is due to its mechanism of action, which is aimed at suppressing the reuptake of serotonin.
Thus, the concentration of the neurotransmitter in the synapse increases, and its effect is enhanced and prolonged. The medication improves mood and stimulates the nervous system, helps to overcome obsessive thoughts and nervous breakdown, removes feelings of anxiety and fear, and reduces appetite. It does not have a sedative effect and does not cause drowsiness.
Prozac is a drug that has antidepressant properties. It stabilizes the nervous system and improves the general condition of the patient. After passing a full therapeutic course, the lack of serotonin is restored. This substance is necessary for the transmission of nerve impulses.
Mechanism of action
Prozac slows down the serotonin uptake. The active substance does not react with other compounds. This indicates that the drug does not interact with cholinergic, adrenergic, histamine, and dopaminergic receptors.
Antidepressants affect the levels of serotonin. Due to this, dysphoria is relieved, fear, anxiety, and tension are removed. The active ingredient does not affect the work of the myocardium. It should be noted that there is no sedative activity. The risk of orthostatic hypotension is minimal.
Prozac can only be prescribed by the attending physician. The drug has a long-lasting effect. The maximum concentration of the active substance in the patient's blood is fixed 7-8 hours after taking a single norm. The medication is allowed to drink both once and during the course. The medicinal composition is excreted through the urinary system.
The active components of the drug are fluoxetine hydrochloride. Additional substances include Dimethicone and starch. The shell contains the following components: patent dye, yellow iron oxide, and titanium dioxide.
Prozac is characterized by relative safety. However, it is strictly forbidden to take it for minor patients, persons with a history of hypersensitivity to the ingredients of the composition.
Special care should be taken when prescribing an antidepressant to patients with suicidal tendencies. Factors that aggravate this condition include severe depression and sleep problems. Among the relative contraindications are old age, diabetes, epilepsy, liver, and kidney diseases. Absolute include glaucoma, convulsive syndrome, benign prostatic hyperplasia. Expressed psychomotor agitation can provoke the development of negative manifestations.
Pregnant women have been prescribed the drug if the intended benefit is greater than the possible risk. If the capsules were prescribed to a woman in the last months of pregnancy, the doctor should regularly monitor the condition of the fetus, and subsequently the newborn child. This is because fluoxetine penetrates the placental barrier and into breast milk.
