Why is Sereupin used? What is it for?

SEREUPIN is a treatment for adults with depression and / or anxiety disorders. The anxiety disorders for which treatment with SEREUPIN is indicated are: obsessive compulsive disorder (repetitive, obsessive thoughts with uncontrollable behavior), panic (panic attacks, including those caused by agoraphobia, or fear of open spaces), social anxiety disorders (being afraid of or avoiding social situations), post-traumatic stress disorder (anxiety caused by a traumatic event), and anxiety disorder "generalized anxiety (generally feeling very anxious or nervous).

SEREUPIN belongs to a group of medicines called SSRIs (selective serotonin reuptake inhibitors). A substance called serotonin is commonly found in the brain. People who are depressed or anxious have lower serotonin levels than others. It is not fully known how SEREUPIN and other SSRIs work, but they can help increase the level of serotonin in the brain. Treating depression or anxiety disorders properly is important to help you feel better.

Contraindications When Sereupin should not be used

Do not take SEREUPIN

If you are taking other medicines called monoamine oxidase inhibitors (MAOIs, including moclobemide and methylthioninium chloride (methylene blue)), or if you have taken them at any time in the last two weeks. Your doctor will advise you on how you should start taking SEREUPIN once you have stopped taking the MAOIs.
If you are taking an anti-psychotic called thioridazine or an anti-psychotic called pimozide.

Children and adolescents under the age of 18

SEREUPIN should not be used in children and adolescents under 18 years of age.

In addition, patients under 18 have an increased risk of side effects such as suicide attempts, suicidal thoughts and hostility (predominantly aggression, oppositional behavior and anger) when taking SEREUPIN. If your doctor has prescribed SEREUPIN for you (or your child) and if you want to talk about it, please go back to your doctor. You should tell your doctor if any of the symptoms listed above appear or worsen when you (or your child) are taking SEREUPIN. Furthermore, the long-term tolerability effects of SEREUPIN related to growth, maturation and cognitive and behavioral development have not yet been demonstrated in this age group.

In studies with SEREUPIN in patients under the age of 18, common side effects affecting less than 1 in 10 children / adolescents were: increased thoughts of suicide and suicide attempts, deliberate harm, hostile behavior , aggressive or unfriendly, loss of appetite, tremors, abnormal sweating, hyperactivity (having too much energy), agitation, change in emotions (including crying and mood swings) and unusual bruising or bleeding (such as nosebleeds). These studies also showed that the same symptoms affected children and adolescents who took sugar pills (placebo) instead of SEREUPIN, although they were observed less often.

In these studies in patients under the age of 18, some patients experienced withdrawal effects after stopping SEREUPIN. These effects were mostly similar to those seen in adults after stopping SEREUPIN (see all " section 3, How to take SEREUPIN) In addition, patients under the age of 18 also commonly (in less than 1 in 10 cases) also experienced stomach pain, feeling jittery and changes in emotions (including crying, mood, attempts to harm yourself, thoughts of suicide and suicide attempts).

You may be more likely to have these kinds of thoughts:

if you have previously had thoughts about killing yourself or harming yourself
if you are a young adult. Data from clinical trials have shown an increased risk of suicidal behavior in adults under the age of 25 with psychiatric disorders who were treated with an antidepressant.

Anytime you have thoughts of harming or killing yourself, contact your doctor or go to a hospital straight away.

As with all antidepressant drugs, the dosage should be reviewed and adjusted as necessary within the first three to four weeks after initiation of therapy and thereafter as deemed clinically appropriate.

In some patients, who have an insufficient response to the 20 mg dose, the dose may be gradually increased up to a maximum of 50 mg per day, in 10 mg increments, based on the patient's response.

Patients with depression should be treated for a sufficient period of at least six months to ensure they are symptom-free.

GENERAL INFORMATIONS

WITHDRAWAL SYMPTOMS OBSERVED AFTER WITHDRAWAL OF PAROXETINE TREATMENT

Abrupt discontinuation of treatment should be avoided (see section 4.4 and section 4.8).

The tapering regimen used in clinical trials used a tapering daily dose of 10 mg at weekly intervals.

If intolerable symptoms occur following dose reduction or upon discontinuation of treatment, resuming the previously prescribed dose may be considered. Thereafter, the doctor may continue to reduce the dose, but more gradually.

Special populations

• Senior citizens

Increased plasma concentrations of paroxetine have been observed in elderly subjects, however the range of plasma concentrations is similar to that seen in younger subjects.

Treatment should start at the same doses as in adults. In some patients, increasing the dose may be useful, but the maximum dose cannot exceed 40 mg per day.

• Children and adolescents (7-17 years)

Paroxetine should not be used for the treatment of children and adolescents as it has been found in controlled clinical trials that paroxetine is associated with an increased risk of suicidal behavior and hostile behavior. Furthermore, efficacy was not adequately demonstrated in these studies (see section 4.4 and section 4.8).

• Children under the age of 7

The use of paroxetine in children less than 7 years of age has not been studied. Paroxetine should not be used until safety and efficacy in this age group have been established.

• Renal / hepatic impairment

Increased plasma concentrations of paroxetine have been reported in patients with severe renal impairment (creatinine clearance less than 30 ml / min) or in patients with hepatic impairment. Therefore, the dosage should be limited to the lowest doses of the dosage range.

Method of administration

It is recommended that paroxetine be administered once daily in the morning with food.

The tablets should be swallowed rather than chewed.

Shake the bottle before use.

04.3 Contraindications

Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.

Paroxetine is contraindicated in combination with monoamine oxidase inhibitors (MAO inhibitors). In exceptional cases, linezolid (an antibiotic which is a reversible non-selective MAO-inhibitor) can be administered in combination with paroxetine provided that careful observation of symptoms of the serotonin syndrome and monitoring of blood pressure is possible (see section 4.5). .

Paroxetine treatment can be initiated:

• two weeks after stopping treatment with an irreversible MAO inhibitor or

• at least 24 hours after stopping treatment with a reversible MAO inhibitor (eg moclobemide, linezolid, methylthioninium chloride (methylene blue, a preoperative visualization agent that is a reversible non-selective MAO inhibitor)).

Initiation of therapy with any MAO inhibitor should occur at least one week after stopping treatment with paroxetine.

Paroxetine should not be used in combination with thioridazine as, as with other CYP450 2D6 hepatic enzyme inhibitors, paroxetine may elevate plasma thioridazine levels (see section 4.5).

Administration of thioridazine alone can induce QTc interval prolongation associated with severe ventricular arrhythmias such as torsades de pointes and sudden death.

Paroxetine should not be used in combination with pimozide (see section 4.5).

04.4 Special warnings and appropriate precautions for use

Treatment with paroxetine should be initiated with caution two weeks after cessation of

treatment with irreversible MAO inhibitors or 24 hours after cessation of treatment with reversible MAO inhibitors. Paroxetine dosage should be gradually increased until an optimal response is achieved (see section 4.3 and section 4.5).

Pediatric population

Paroxetine should not be used to treat children and adolescents under 18 years of age. Suicidal behaviors (suicide attempts and suicidal ideation) and hostility (predominantly aggression, oppositional behavior and anger) were observed more frequently in clinical trials in children and adolescents treated with antidepressants than in those treated with placebo. If, based on medical needs, a decision is made to carry out the treatment anyway, the patient should be carefully monitored for the appearance of suicidal symptoms. Furthermore, long-term safety data in children and adolescents relating to growth, maturation and cognitive and behavioral development are not available.

Suicide / suicidal thoughts or clinical worsening

Depression is associated with an increased risk of suicidal thoughts, self harm and suicide (suicide / related events). This risk persists until significant remission occurs. As improvement may not occur during the first or immediate weeks of treatment, patients should be monitored closely until improvement occurs. It is generally clinical experience that the risk of suicide may increase in the early stages of improvement.

Other psychiatric conditions for which paroxetine is prescribed may also be associated with an increased risk of suicidal behavior. Furthermore, these conditions can be associated with major depressive disorder. Therefore, the same precautions followed when treating patients with other psychiatric disorders should be observed when treating patients with major depressive disorders.

Patients with a history of suicidal behavior or thoughts, or who exhibit a significant degree of suicidal ideation prior to initiation of treatment, are at increased risk of suicidal thoughts or suicidal thoughts, and should be closely monitored during treatment.

A meta-analysis of clinical trials conducted with antidepressant drugs compared to placebo in the therapy of psychiatric disorders showed an increased risk of suicidal behavior in the age group below 25 years of patients treated with antidepressants compared to placebo (see also section 5.1). .

Drug therapy with antidepressants should always be associated with close surveillance of patients, particularly those at high risk, especially in the initial stages of treatment and after dose changes.

Patients (or caregivers) should be advised of the need to monitor and report immediately to their physician any worsening clinical picture, the onset of suicidal behavior or thoughts, or changes in behavior.

Akathisia / psychomotor agitation

The use of paroxetine has been associated with the development of akathisia, characterized by an internal feeling of restlessness and psychomotor agitation such as an inability to sit or stand still, usually associated with subjective malaise. This is most likely to happen within the first few weeks of treatment. In patients with these symptoms, increasing the dosage can be harmful.

Serotonin syndrome / neuroleptic malignant syndrome

On rare occasions, there have been reports of serotonin syndrome or neuroleptic malignant syndrome in association with paroxetine treatment, particularly when administered concomitantly with other serotonergic and / or neuroleptic drugs. Since these syndromes can lead to potentially life-threatening conditions, treatment with

paroxetine in case of occurrence of such events (characterized by pictures of symptoms, such as hyperthermia, rigidity, myoclonus, instability of the autonomic system with possible rapid fluctuation of vital signs, changes in mental status including confusion, irritability, extreme agitation leading to delirium and coma) and symptomatic supportive treatment should be initiated. Paroxetine should not be used in combination with serotonin precursors (such as L-tryptophan, oxitriptan) due to the risk of serotonin syndrome (see sections 4.3 and 4.5).

Mania

As with all antidepressants, paroxetine should be used with caution in patients with a history of mania.

Paroxetine should be discontinued in all patients entering a manic phase.

Renal / hepatic insufficiency

Caution is recommended in patients with severe renal insufficiency or in patients with hepatic insufficiency (see section 4.2).

Diabetes

In diabetic patients, treatment with SSRIs can impair glycemic control. The dosage of insulin and / or oral hypoglycaemics may need to be adjusted.

In addition, there have been studies suggesting that an increase in blood glucose may occur when paroxetine and pravastatin are co-administered (see section 4.5).

Epilepsy

As with other antidepressants, paroxetine should be used with caution in patients with epilepsy.

Seizures

The overall incidence of seizures in patients treated with paroxetine is less than 0.1%. The drug should be discontinued in all patients who present with seizures.

Electroconvulsive Therapy (ECT)

There is limited clinical experience in the concomitant administration of paroxetine with electroconvulsive therapy (ECT).

Glaucoma

As with other SSRIs, paroxetine can cause mydriasis and should be used with caution in patients with narrow-angle glaucoma or a history of glaucoma.

Cardiovascular pathologies

In patients with cardiovascular diseases the usual precautions should be observed.

Hyponatremia

Hyponatremia has been reported rarely, predominantly in the elderly. Caution should also be exercised in those patients at risk of hyponatremia, for example from concomitant medications and cirrhosis. Hyponatremia is usually reversible after discontinuation of paroxetine.

Hemorrhages

Cases of cutaneous bleeding disorders such as ecchymosis and purpura have been reported with SSRIs. Other haemorrhagic manifestations have been reported, for example gastrointestinal and gynecological haemorrhages.

Elderly patients may be at increased risk for non-menstruation-related bleeding.

Caution is advised in patients taking SSRIs concomitantly with oral anticoagulants, drugs known to affect platelet function, or other drugs that may increase the risk of bleeding (e.g. atypical antipsychotics such as clozapine, phenothiazine, most tricyclic antidepressants, acid acetylsalicylic, non-steroidal anti-inflammatory drugs (NSAIDs), COX-2 inhibitors) and moles

patients with a history of bleeding disorders or conditions that may predispose to bleeding (see section 4.8).

Interaction with tamoxifen

Paroxetine, a potent inhibitor of CYP2D6, may lead to decreased concentrations of endoxifen, one of the most important active metabolites of tamoxifen. Therefore, paroxetine should be avoided whenever possible during treatment with tamoxifen (see section 4.5).

Drugs that affect gastric pH

In patients taking the oral suspension, the plasma concentration of paroxetine may be affected by gastric pH. Data in vitro showed that an acidic environment is required for the release of the active drug from the suspension, so the absorption can be reduced in patients with an elevated gastric pH or with achlorhydria, as after the use of some drugs (antacids, receptor antagonists H2 histaminergics, proton pump inhibitors), in some diseases (e.g. atrophic gastritis, pernicious anemia, chronic Helicobacter pylori infection), and after surgery (vagotomy, gastrectomy). Dependence on pH should be taken into account when using a different pharmaceutical form of paroxetine (eg plasma concentration of paroxetine may decrease in patients with elevated gastric pH switching from tablets to oral suspension). Therefore, caution is recommended in patients starting or ending treatment with drugs that increase gastric pH. In such situations a dose adjustment may be necessary.

Withdrawal symptoms observed on discontinuation of paroxetine treatment

Discontinuation symptoms observed when treatment is stopped are common, particularly in the event of abrupt discontinuation (see section 4.8).

In clinical trials, adverse events observed with treatment discontinuation occurred in 30% of patients taking paroxetine, compared with 20% of patients taking placebo:

the onset of withdrawal symptoms is not the same in cases where a drug is addictive or addictive.

The risk of withdrawal symptoms may be dependent on several factors, including the duration of therapy, the dose and the rate of dose reduction.

Dizziness, sensory disturbances (including paraesthesia, electric shock sensation and tinnitus), sleep disturbances (including intense dreams), agitation or anxiety, nausea, tremor, confusion, sweating, headache, diarrhea, palpitations, emotional instability, have been reported. irritability and visual disturbances. Generally, the intensity of these symptoms is mild to moderate, however in some patients they may be severe. They usually appear within the first few days of stopping treatment, but there have been very rare cases in which they have appeared in patients who inadvertently skipped. one dose.

Generally these symptoms are self-limiting, and usually resolve within two weeks, although in some individuals they may last longer (two to three months or more). It is recommended that the dose of paroxetine should be reduced gradually, when treatment is discontinued, over a period of several weeks or months, depending on the patient's need (see "Withdrawal Symptoms Observed After Stopping Paroxetine Treatment. "in paragraph 4.2).

Important information about some of the ingredients

Parabens

Paroxetine oral suspension contains methyl parahydroxybenzoate (E218) and propyl parahydroxybenzoate (E216) (parabens), which can cause allergic reactions (including delayed).

Orange yellow dye

Paroxetine oral suspension contains yellow-orange dye FCF (E110), which may cause allergic reactions.

Sorbitol E420

Paroxetine oral suspension contains sorbitol (E420). Patients with rare rare hereditary problems of fructose intolerance should not take this medicine.

04.5 Interactions with other medicinal products and other forms of interaction

Serotonergic drugs

As with other SSRIs, co-administration with serotonergic drugs may lead to the onset of serotonin-associated effects (serotonin syndrome: see section 4.4). Caution should be advised and closer clinical monitoring is required when serotonergic drugs (such as L-tryptophan, triptans, tramadol, linezolid, methylthioninium chloride (methylene blue), SSRIs, lithium, pethidine and St. John's wort preparations - Hypericum perforatum) are administered concomitantly with paroxetine. Caution is also advised with fentanyl, used in general anesthesia or in the treatment of chronic pain. The concomitant use of paroxetine and MAO inhibitors is contraindicated due to the risk of serotonin syndrome (see section 4.3).

Pimozide

A mean 2.5-fold increase in pimozide levels occurred in a low single dose study of pimozide (2 mg) when it was co-administered with paroxetine (at a dose of 60 mg). This can be explained on the basis of the inhibitory effect that paroxetine has on CYP2D6. Due to the reduced therapeutic index of pimozide and its known ability to prolong the QT interval, concomitant use of pimozide and paroxetine is contraindicated (see section 4.3 ).

Enzymes responsible for drug metabolism

The metabolism and pharmacokinetics of paroxetine may be affected by the induction or inhibition of drug metabolizing enzymes.

When paroxetine is administered concomitantly with a drug known to inhibit enzyme metabolism, the use of the lowest doses in the dosage range should be considered.

No starting dose adjustment is required when co-administered with drugs known to induce enzyme metabolism (e.g. carbamazepine, rifampicin, phenobarbital, phenytoin), or with fosamprenavir / ritonavir. Any modification of the paroxetine dosage (either after initiation or following discontinuation of a metabolic inducing drug) should be based on clinical response (tolerability and efficacy).

Neuromuscular blockers

SSRIs may reduce plasma cholinesterase activity resulting in prolongation of the neuromuscular blocking action of mivacurium and succinylcholine.

Fosamprenavir / ritonavir

Co-administration of fosamprenavir / ritonavir 700/100 mg twice daily with paroxetine 20 mg daily to healthy volunteers for 10 days significantly reduces plasma paroxetine levels by approximately 55%. Plasma levels of fosamprenavir / ritonavir during co-administration with paroxetine were similar to reference values from other studies, indicating that paroxetine has no significant effect on the metabolism of fosamprenavir / ritonavir. There are no data on the long-term effect of co-administration of paroxetine and fosamprenavir / ritonavir for longer than 10 days.

Procyclidine

Daily administration of paroxetine significantly increases the plasma levels of procyclidine. If anticholinergic effects are observed, the dose of procyclidine should be reduced.

Anticonvulsants

Carbamazepine, phenytoin, sodium valproate. Concomitant administration does not appear to show

no effect on the pharmacokinetic and pharmacodynamic profile in epileptic patients.

Inhibitory potency of paroxetine on CYP2D6

Like other antidepressants, including other SSRIs, paroxetine inhibits the hepatic cytochrome P450 enzyme CYP2D6. Inhibition of CYP2D6 may lead to increased plasma concentrations of co-administered drugs metabolised by this enzyme. They include these drugs. some tricyclic antidepressants (e.g. clomipramine, nortriptyline and desipramine), phenothiazine neuroleptics (e.g. perphenazine and thioridazine, see section 4.3), risperidone, atomoxetine, some Type 1 C antiarrhythmics (e.g. propafenone and flecainide) and metoprolol.

The use of paroxetine in combination with metoprolol administered in heart failure is not recommended due to the reduced therapeutic index of metoprolol in this indication.

Pharmacokinetic interaction between CYP2D6 inhibitors and tamoxifen has been reported in the literature, showing a 65-75% reduction in plasma levels of endoxifen, one of the most active forms of tamoxifen. In some studies, reduced efficacy of tamoxifen has been reported with the concomitant use of some SSRI antidepressants. Since a reduced effect of tamoxifen cannot be excluded, concomitant administration with potent CYP2D6 inhibitors (including paroxetine) should be avoided whenever. possible (see section 4.4).

Alcohol

As with other psychotropic drugs, patients should be advised to avoid alcohol use while taking paroxetine.

Oral anticoagulants

There may be a pharmacodynamic interaction between paroxetine and oral anticoagulants. Concomitant use of paroxetine and oral anticoagulants may lead to increased anticoagulant activity and the risk of bleeding. Therefore paroxetine should be used with caution in patients receiving oral anticoagulants (see section 4.4).

Non-steroidal anti-inflammatory drugs (NSAIDs), acetylsalicylic acid and other antiplatelet agents

A pharmacodynamic interaction between paroxetine and NSAID / acetylsalicylic acid may occur. Concomitant use of paroxetine and NSAIDs / acetylsalicylic acid may lead to an increased risk of haemorrhage (see section 4.4).

Caution is advised in patients taking SSRIs concomitantly with oral anticoagulants, drugs known to affect platelet function or other drugs that may increase the risk of bleeding (e.g. atypical antipsychotics such as clozapine, phenothiazine, most tricyclic antidepressants, acetylsalicylic acid , non-steroidal anti-inflammatory drugs (NSAIDs), COX-2 inhibitors) and in patients with a history of bleeding disorders or conditions that may predispose to bleeding.

Pravastatin

Interaction between paroxetine and pravastatin has been observed in studies suggesting that co-administration of paroxetine and pravastatin may lead to an increase in the blood glucose level. Patients with diabetes mellitus receiving both paroxetine and pravastatin may require dose adjustments of the hypoglycaemic agents and / or insulin (see section 4.4).

Drugs that affect gastric pH

Data in vitro showed that the release of paroxetine from the oral suspension is pH-dependent.Therefore, drugs that alter gastric pH (such as antacid drugs, proton pump inhibitors or histamine H2 receptor antagonists) may affect the plasma concentrations of paroxetine in patients taking the oral suspension (see section 4.4).

04.6 Pregnancy and lactation

Pregnancy

Some epidemiological studies have indicated an increased risk of congenital malformations, particularly cardiovascular (eg ventricular and atrial septal defects) associated with paroxetine use during the first trimester of pregnancy. The mechanism is unknown. The data indicate that the risk of giving birth to a newborn with a cardiovascular defect following maternal exposure to paroxetine is less than 2/100 compared to the risk of approximately 1/100 expected for such defects in the general population.

Paroxetine should only be administered during pregnancy when strictly indicated. The physician, at the time of the prescription, will have to evaluate the option of alternative treatments in women who are pregnant or who are planning to become pregnant. Abrupt termination during pregnancy should be avoided (see "Withdrawal symptoms observed following discontinuation of paroxetine treatment" in section 4.2).

Newborns should be observed if maternal use of paroxetine continues into the later stages of pregnancy, particularly in the third trimester.

The following symptoms may occur in newborns following maternal use of paroxetine in the later stages of pregnancy: respiratory distress, cyanosis, apnea, seizures, unstable temperature, difficulty in feeding, vomiting, hypoglycemia, hypertonia, hypotonia, hyperreflexia , tremor, nervousness, agitation, irritability, lethargy, constant crying, drowsiness and difficulty falling asleep. These symptoms may be due to either serotonergic effects or withdrawal symptoms. In most cases, complications begin immediately upon delivery. delivery or soon after (less than 24 hours).

Epidemiological data have suggested that the use of SSRIs during pregnancy, particularly during late pregnancy, may cause an increased risk of persistent pulmonary hypertension of the newborn (PPHN). The observed risk was approximately five in 1000 pregnancies. general population one to two cases of PPHN occur in 1000 pregnancies.

Studies in animals have shown reproductive toxicity but did not indicate direct harmful effects with respect to pregnancy, embryo-fetal development, parturition or postnatal development (see section 5.3).

Feeding time

Small amounts of paroxetine are excreted in breast milk. In published studies, serum concentrations in breastfed infants were not detectable (sign of drug effect. Since no effects are expected, breastfeeding may be considered.

Fertility

Animal data have shown that paroxetine may affect sperm quality (see section 5.3). In vitro data on human material show some effect on sperm quality, however, in humans, patients treated with SSRIs (including paroxetine) have shown that the effect on sperm quality is reversible. Impact on fertility has not been observed so far.

04.7 Effects on ability to drive and use machines

Clinical experience has shown that paroxetine therapy is not associated with impaired cognitive or psychomotor functions. However, as with all psychoactive drugs, patients should be advised to exercise caution when driving and operating machinery.

Although paroxetine does not increase the psychic and motor damaging effects induced by alcohol intake, concomitant use of paroxetine and alcohol is not recommended.

It is therefore recommended that, if treatment with paroxetine is no longer required, there is a gradual discontinuation, conducted by a gradual decrease of the dose (see section 4.2 and section 4.4).

ADVERSE EVENTS OBSERVED DURING CLINICAL STUDIES IN PEDIATRIC AGE PATIENTS

The following adverse events were observed:

Increased suicide-related behaviors (including suicide attempts and suicidal thoughts), self-harming behavior and increased hostile attitude. Suicidal thoughts and suicide attempts were mainly observed in clinical trials with adolescents with Major Depressive Disorder. "hostile attitude has particularly occurred in children with OCD, and especially in children under the age of 12.

Additional events observed were: decreased appetite, tremor, sweating, hyperkinesia, agitation, emotional lability (including crying and mood fluctuations), bleeding-related adverse events, especially of the skin and mucous membranes.

Events observed after discontinuation / tapering of paroxetine are: emotional lability (including crying, mood swings, self harm, suicidal thoughts and suicide attempts), nervousness, dizziness, nausea and abdominal pain (see section 4.4).

See section 5.1 for more information on clinical studies.

Reporting of suspected adverse reactions

Reporting of suspected adverse reactions occurring after authorization of the medicinal product is important as it allows continuous monitoring of the benefit / risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system. "Street address: www.aifa.gov.it/responsabili

04.9 Overdose

Symptoms and signs

Based on the available information regarding overdose with paroxetine, a large margin of safety appears evident.

Experience with paroxetine overdose has indicated that, in addition to the symptoms described in section 4.8 "Undesirable effects", fever and involuntary muscle contractions have been reported.

Patients generally recovered without serious sequelae even in cases where paroxetine was taken alone up to doses of 2000 mg. Events such as coma or ECG changes have occasionally been reported, very rarely with a fatal outcome, but generally when paroxetine was taken in combination with other psychotropic drugs, with or without alcohol.

Treatment

No specific antidote is known.

Treatment should be based on the general measures used in the treatment of overdose with antidepressants. To reduce the absorption of paroxetine, administration of 20-30 g of activated charcoal may be considered, if possible within hours of taking the overdose. Supportive therapy with careful observation and frequent monitoring of vital signs is indicated. Patient management should follow clinical indications.

05.0 PHARMACOLOGICAL PROPERTIES

05.1 Pharmacodynamic properties

Pharmacotherapeutic group: Antidepressants - selective serotonin reuptake inhibitors, ATC code: N06A B05

Mechanism of action

Paroxetine is a potent and selective 5-hydroxytryptamine (5-HT; serotonin) reuptake inhibitor; its antidepressant action and its efficacy in the treatment of obsessive compulsive disorder, social anxiety disorder / social phobia, generalized anxiety disorder, post-traumatic stress disorder and panic disorder are believed to be related to this specific inhibition of reuptake of 5-HT in brain neurons.

Paroxetine is not chemically related to tricyclics, tetracyclics and other available antidepressants.

Paroxetine has low affinity for muscarinic-type cholinergic receptors and studies in animals have shown only weak anticholinergic properties.

In accordance with this selectivity of action, studies in vitro showed that, unlike tricyclic antidepressants, paroxetine has low affinity for alpha 1, alpha 2 and beta-adrenoceptors, for dopaminergic receptors (D2), for 5-HT1 like and 5-HT2 receptors, and for those of "histamine (H1). This lack of interaction with postsynaptic receptors in vitro has been confirmed by studies in vivo, which demonstrated the absence of depressive properties on the central nervous system and of hypotensive properties.

Pharmacodynamic effects

Paroxetine does not alter psychomotor functions and does not potentiate the depressive effects of ethanol.

Similar to other selective serotonin reuptake inhibitors, paroxetine causes symptoms related to excessive stimulation of the serotonin receptor when administered to animals previously treated with monoamine oxidase (MAO) inhibitors or tryptophan.

Behavioral and EEG studies indicate that paroxetine is weakly activating at doses generally higher than those required to inhibit serotonin reuptake. The activating properties are not by nature "amphetamine-like". Animal studies indicate that paroxetine is well tolerated by the cardiovascular system. Paroxetine does not cause significant changes in blood pressure, heart rate and ECG after administration to healthy subjects.

Studies indicate that paroxetine, unlike antidepressants which inhibit noradrenaline reuptake, has a more reduced propensity to inhibit the antihypertensive effects of guanethidine.

Paroxetine, in the treatment of depressive disorders, demonstrates efficacy comparable to that of standard antidepressants.

There is also some evidence that paroxetine may have therapeutic value in patients who are unresponsive to standard therapy.

Administration of the dose in the morning has no adverse effect on the quality or duration of sleep. Additionally, patients may report improved sleep when they respond to paroxetine therapy.

Analysis of suicidality in adults

A paroxetine-specific analysis of clinical trials conducted in comparison with placebo in adult patients with psychiatric disorders showed a higher frequency of suicidal behavior in young adults (aged 18 to 24 years) treated with paroxetine compared to placebo ( 2.19% compared to 0.92%). In the older age group, no such increase was observed. In adults (of all ages) with major depressive disorder, there was an increased frequency of suicidal behavior in patients treated with paroxetine compared to placebo (0.32% compared to 0.05%); all events were suicide attempts. However, the majority of such attempts for paroxetine (8 of 11) occurred in young adults (see also section 4.4).

Dose response

In fixed dose studies, the dose response curve is flat, not indicating an advantage in terms of efficacy in using higher than recommended doses. However, there are some clinical data that

suggest that subsequent dose increases may be of benefit to some patients.

Long-term efficacy

The long-term efficacy of paroxetine in depression was demonstrated in a 52-week maintenance study designed to evaluate relapse prevention: relapses in patients treated with paroxetine (20-40 mg per day) occurred in the 12% of cases, compared to 28% of cases in patients taking placebo.

The long-term efficacy of paroxetine in the treatment of OCD was examined in three 24-week maintenance studies, designed to evaluate relapse prevention. In one of the three studies, a significant difference was achieved in the proportion of patients with relapses between paroxetine (38%) and placebo (59%).

The long-term efficacy of paroxetine in the treatment of panic disorder was demonstrated in a 24-week maintenance study designed to evaluate relapse prevention: relapses in patients treated with paroxetine (10-40 mg per day) occurred in 5% of cases, compared to 30% of patients taking placebo.This was supported by a 36-week maintenance study.

The long-term efficacy of paroxetine in the treatment of social and generalized anxiety disorders and post-traumatic stress disorder has not been sufficiently demonstrated.

Adverse events observed in clinical trials in pediatric patients

During short-term clinical trials (up to 10-12 weeks) in children and adolescents, the following adverse events have been observed in patients treated with paroxetine with a frequency of at least 2% of patients and these events occurred with an incidence at least twice as high as placebo: increased suicide-related behaviors (including suicide attempts and suicidal thoughts), self-harming behavior and increased hostile attitude. Suicidal thoughts and suicide attempts were mainly observed in clinical trials with adolescents with Major Depressive Disorder. The increased hostile attitude occurred particularly in children with OCD, especially in children under the age of 12. Additional events that were observed more frequently in the paroxetine group than in the paroxetine group. that treated with placebo were: decrease in appetite, tremor, sweating, hyperkinesis, agitation, emotional lability (including crying and mood swings).

In studies where the tapering regimen was used, symptoms reported during the tapering phase or upon discontinuation of paroxetine, observed with a frequency of at least 2% of patients and occurring occurred with at least two times higher incidence than placebo were: emotional lability (including crying, mood fluctuations, self-harm, suicidal thoughts and suicide attempts), nervousness, dizziness, nausea and abdominal pain (see section 4.4 ).

In five parallel group studies of treatment duration from eight weeks to eight months, bleeding-related adverse events, mainly of the skin and mucous membranes, were observed at a frequency of 1.74% in patients treated with paroxetine compared to a frequency of 0.74% observed in patients treated with placebo.

05.2 Pharmacokinetic properties

Absorption

Paroxetine is well absorbed after oral administration and undergoes first pass metabolism.

Due to first pass metabolism, the amount of paroxetine available in the systemic circulation is less than that absorbed from the gastrointestinal tract. In case of increased body burden following higher single doses or multiple doses, partial saturation of the first pass effect and a reduction in plasma clearance occur. This leads to a disproportionate increase in plasma concentrations of paroxetine and therefore Pharmacokinetic parameters are not constant, resulting in non-linear kinetics, however non-linearity is generally

modest and is limited to those subjects who reach low plasma levels at low doses.

Systemic steady-state levels are achieved within 7-14 days of initiation of treatment with the immediate or controlled release formulations and pharmacokinetics do not appear to change during long-term treatment.

Distribution

Paroxetine is widely distributed in tissues and pharmacokinetic calculations indicate that only 1% of the paroxetine present in the body is found in the plasma. About 95% of the paroxetine present in plasma is bound to proteins at therapeutic concentrations.

No correlation has been demonstrated between paroxetine plasma concentrations and clinical effects (adverse events and efficacy).

Biotransformation

The major metabolites of paroxetine are polar and conjugated products of oxidation and methylation, which are readily cleared. In view of their relative lack of pharmacological activity, they are extremely unlikely to contribute to the therapeutic effects of paroxetine.

Metabolism does not compromise the selectivity of action of paroxetine on neuronal reuptake of serotonin.

Elimination

Urinary excretion of unchanged paroxetine is generally less than 2%, while that of metabolites is about 64% of the dose. Approximately 36% of the dose is excreted in the faeces, probably via bile, of which unchanged paroxetine represents less than "1% of the dose. Thus paroxetine is almost completely eliminated by metabolism.

Excretion of metabolites is biphasic, being initially the result of first pass metabolism and subsequently controlled by the systemic elimination of paroxetine.

The elimination half-life is variable but is generally about one day.

Special patient populations

Elderly and renal / hepatic insufficiency

An increase in plasma concentrations of paroxetine has been observed in elderly subjects and in subjects with severe renal insufficiency and in subjects with hepatic insufficiency, but the range of plasma concentrations is similar to that of healthy adult subjects.

05.3 Preclinical safety data

Toxicological studies were conducted in the rhesus monkey and in the albino rat; in both species the metabolic profile is similar to that described in humans. As expected with lipophilic amines, including tricyclic antidepressants, phospholipidosis was detected in rats. Phospholipidosis was not observed in primate studies, lasting up to a year, at doses six times higher than the recommended clinical dose range.

Carcinogenicity: In two-year studies in mice and rats, paroxetine did not show carcinogenic effects.

Genotoxicity: Genotoxicity was not observed in a series of tests in vitro And in vivo.

Reproductive toxicity studies in rats showed that paroxetine affects male and female fertility by reducing the fertility index and the pregnancy rate. In rats, higher infant mortality and delayed ossification were observed. The latter effects are likely related to maternal toxicity and are not considered to be a direct effect on the fetus / neonate.
