Venlaxor is an antidepressant.
Indications of the venlaksora
It is used to prevent or eliminate depressions of various origins.
Release form
The release is produced in tablets with a volume of 37.5, and 75 mg - 10 pieces inside blister packs. The box contains 3 such plates.
Pharmacodynamics
The structure of Venlaxor does not allow to attribute it to some category of antidepressants. Antidepressant medicinal effect and mechanisms of LS influence are conditioned by the fact that the drug is capable of potentiating the transmission of nerve signals. The active element and its product of EFA metabolism are SSRIs, as well as IONS, and besides this substance, which slows down the processes of dopamine capture.
The therapeutic course with the use of medication (single or multiple use) helps to reduce β-adrenergic reactivity. The drug has no tropism for benzodiazepine, opioid, and also non-ciclidine endings.
Pharmacokinetics
The drug is well absorbed inside the digestive tract. The maximum values of the substance within the blood plasma after a single use of 25-150 mg portions are 33-173 ng / ml. These indicators are kept in the body for 24 hours.
Inside the liver, metabolic processes are carried out. The product of drug metabolism is O-desmethylvenlafaxine (EFA) substance, which has medicinal properties similar to the active element.
The half-life of the active component not metabolized is 5 hours; a similar indicator for EFA is 11 hours. Synthesis of the drug with proteins - 30%.
Excretion is mainly done by the kidneys.
In the case of tablets taken with food, the duration of the peak period for drugs within the blood is prolonged for 30 minutes.
If the patient is ill with hepatic cirrhosis, the metabolic rate of the products inside the blood increases, and the process of excretion, on the contrary, becomes slower.
With a severe or moderate degree of kidney failure, Venlaksor's clearance and its elements decrease. The sex and age of patients does not affect the pharmacokinetic characteristics of the medication.
Dosing and administration
You need to take the tablets inside, along with the food, twice a day (1 tablet with a volume of 37.5 mg), in the morning, and also in the evening. The daily dosage is 75 mg. After 2-3 weeks, if the effect of taking drugs is not observed, it is possible to increase the daily dose to 150 mg.
During treatment of severe forms of depression, higher dosages are allowed - start therapy with a two-time intake of 75 mg LS. The daily portion in the presence of the need is allowed to increase by 75 mg at intervals of 3 days. You need to do this until the medication is achieved.
The maximum allowable size of a daily portion is 375 mg. When the desired result is achieved, the serving size must be gradually reduced to the minimum values. Supportive treatment, as well as the prevention of the development of negative symptoms with the intake of minimum allowable portions are allowed to be carried out for six months.
With insufficient kidneys at an easy stage, the size of the daily dosage should not be adjusted. With a moderate stage of the disease - you need to reduce the size of the dose by 25-50% (due to the fact that in this case the half-life will increase). Persons with a serious stage of pathology are forbidden to take medicine. For people who undergo hemodialysis procedures, they complete half the daily dosage at the end.
Very cautiously, Venlaxor should be taken by elderly people - in order to prevent a negative impact on renal activity. This group of patients receiving a minimum effective daily dose, and if the need for its increase, the patient should be monitored by the doctor.
To abolish the use of drugs should be gradually - for a minimum of 7-14 days, during which the dose rate gradually decreases. The end of the medication is determined by the size of the portions, the duration of the course and the individual needs of the patient.

The combination with clusepidom increases the level of medication in the blood, which can lead to the development of epileptic seizures.
The use of warfarin together with Venlaxor increases the anticoagulant effect of the first drug.
