Paxil (Generic) is a strong antidepressant.
After receipt of the drug in the gastrointestinal tract, its absorption occurs, followed by a process of metabolism by first passing through the liver. The equilibrium concentration of the drug is achieved after 7-14 days of therapy. The drug is characterized by a nonlinear dependence of pharmacokinetic parameters on the dose and treatment period. Paxil (Generic) is extensively distributed in tissues, only 1% of the dose taken is present in plasma.
Metabolism of the drug occurs in the liver with the formation of inactive metabolites. The major metabolites include conjugated and polar oxidation and methylation products, which have negligible pharmacological activity.
The selective capture of serotonin by neurons due to the action of Paxil (Generic) is not disturbed in the process of metabolism. Through the kidneys, 64% of Paxil (Generic) is excreted as metabolites and 2% in unchanged form.
Less than 1% is excreted through the intestines in unchanged form, and the rest of the preparation is in the form of metabolites. The first phase of excretion of metabolites occurs as a result of the first passage of Paxil (Generic) through the liver.
In the second phase, the excretion process is controlled by systemic elimination.
In case of impaired liver or kidney function and if you old, the level of concentration of paroxetine in the blood plasma increases.
