Release form

The drug is available in biconvex tablets, packaged in blisters of 10 pcs., In one package there can be one, three or ten blisters.

Pharmachologic effect

Renders antidepressant effect by the mechanism of specific inhibition by reuptake serotonin in functional brain cells - neurons.

Pharmacodynamics and pharmacokinetics

Has a low affinity for muscarinic cholinergic receptors. As a result of the research, data were obtained that:

  • On animals anticholinergic properties manifest weakly.
  • In vitro Paroxetine Studies - Weak Affinity α1-, α2- and β-adrenergic receptorsincluding to dopamine (D2), serotonin subtype 5-HT1- and 5-NT2-, including histamine receptors (H1).
  • In vivo studies confirm in vitro results - does not interact with postsynaptic receptors and does not depress the central nervous system and does not cause arterial hypotension.
  • Without breaking psychomotor functions, paroxetine does not increase the inhibitory effect ethanolon central nervous system.
  • Study behavioral changes and EEG showed that paroxetine is able to cause a weak activating effect in a dose exceeding the retardation of serotonin reuptake, while the mechanism is not amphetamine-like.
  • On a healthy body, paroxetine does not have significant changes in blood pressure (blood pressure), Heart rateand ECG.

As for the pharmacokinetics, after oral administration, the drug absorbedand metabolizedwith the "first passage" of the liver, resulting in bloodless paroxetine than absorbed from the digestive tract. By increasing the amount of paroxetine in the body (a single dose of large doses or multiple doses of the usual doses), partial saturation is achieved metabolic pathway and reduced clearance of paroxetine plasma, leading to a disproportionate increase in plasma paroxetine concentrations. This means that the pharmacokinetic parameters are unstable and the kinetics is nonlinear. However, nonlinearity is usually poorly expressed and is observed in patients taking low doses of the drug, which cause low levels of paroxetine in plasma. It is possible to achieve equilibrium plasma concentration in 1-2 weeks.

Paroxetine is distributed in the tissues, and according to pharmacokinetic calculations, 1% of the total amount of paroxetine that is present in the body remains in plasma. At therapeutic concentrations, approximately 95% of plasma paroxetine is associated with squirrels. No relationship was found between the concentration of paroxetine in plasma and clinical effects, adverse reactions. He is able to penetrate breast milk and in embryos.

Biotransformationoccurs in 2 phases: including primary metabolismand system eliminationbefore inactive polar and conjugated products as a result of the process oxidationand methylation. Half-life varies between 16-24 hours. Approximately 64% are excreted in the urine as metabolites, 2% - unchanged; the rest - with feces as metabolitesand 1% - unchanged.

Indications for use

The drug is used for all types depression in adults, including reactive and severe, accompanied by anxiety, obsessive-compulsive disorder for maintenance and preventive therapy. Children and adolescents 7-17 years old with panic disorders with agoraphobia and without, social phobias, generalized anxiety disorders, post-traumatic stress disorders.


Hypersensitivity to paroxetine or other constituent components.

Side effects

A decrease in the frequency and intensity of individual side effects of paroxetine occurs as treatment progresses, and therefore does not require cancellation. The frequency gradation is as follows:

  • very often (≥1 / 10);
  • often (≥1 / 100, <1/10);
  • sometimes happens (≥1 / 1000, <1/100);
  • rarely (≥1 / 10,000, <1/1000);
  • very rarely (<1/10 000), given individual cases.

Frequent and very frequent occurrence is determined on the basis of generalized data on the safety of the drug in more than 8 thousand patients. Clinical trials were conducted to calculate differences in the incidence of side effects in the Paxil group and the second placebo group. The occurrence of side effects of Paxil rare or very rare is determined based on post-marketing information on the frequency of messages, and not the true frequency of these effects.

Side effects indicators are stratified by organs and frequency:

  • Blood and lymphatic system: rarely happen abnormal bleeding(hemorrhage in the skin and mucous membranes). Very rarely possible thrombocytopenia.
  • Endocrine system: very rarely - violation of secretion ADH.
  • The immune system: very rarely happen allergic reactions of type urticaria and angioedema.
  • Metabolism: "often" cases of decline appetite, sometimes in elderly patients with impaired ADH secretion - hyponatremia.
  • CNS: often arises drowsinessor insomnia, convulsive seizures; seldom - blurred consciousness, hallucinations, manic reactions as possible symptoms of the disease itself.
  • Vision: very rarely occurs exacerbation of glaucomahowever, “often” is blurred vision.
  • The cardiovascular system: "rarely" noted sinus tachycardiaas well as a transient decline or increase in blood pressure.
  • Respiratory system, chest and mediastinum: "often" noted yawn.
  • Gastrointestinal tract:"very often" fixed nausea; often - constipationor diarrhea at dry mouth; gastrointestinal bleeding is very rare.
  • Hepatobiliary system: quite "rare" was observed an increase in the level of production liver enzymes; very rare cases hepatitis Aaccompanied by jaundiceand / or liver failure.
  • Epidermis: often recorded sweating; rare case skin rashesand very rare - reactions photosensitivity.
  • urinary system: rarely recorded the delay urine.
  • Reproductive system: very often - cases sexual dysfunction; seldom - hyperprolactinemia and galactorrhea.
  • Among the common violations: often fixed astheniaand very rarely - peripheral edema.

An approximate list of symptoms that may occur after completion of the course is established. paroxetine: "often" noted dizziness and others sensory disturbancessleep disturbances, the presence of anxiety, headache; sometimes - strong emotional arousal, nausea, tremor, sweating, as well as diarrhea. Most often, these symptoms in patients are mild and mild, pass without intervention. Groups of patients at increased risk of side effects have not been registered, but if there is no greater need for treatment with paroxetine, the dose is gradually reduced until completely withdrawn.

Paroxetine does not have specific antidote.


Paroxetine is not recommended for use with MAO inhibitors, and also within 2 weeks after completion of the course; in combination with thioridazine, because, like other drugs that inhibit activity enzyme CYP2 D6 cytochrome P450, increases the concentration of thioridazine in plasma. Paxil is able to enhance the action of alcohol-containing agents and reduce the effectiveness Digoxin and Tamoxifene. Microsomal Oxidation Inhibitors and Cimetidineincrease the activity of paroxetine. Applying with indirect coagulants or antithrombotic agents, an increase in bleeding is observed.
