Paroxétine Evolugen
Paroxétine Evolugen Uses, Dosage, Side Effects, Food Interaction and all others data.
The efficacy of Paroxétine Evolugen is presumed to be linked to potentiation of serotonergic activity in the central nervous system resulting from inhibition of neuronal reuptake of serotonin (5-hydroxy-tryptamine, 5 HT). Studies at clinically relevant doses in humans have demonstrated that paroxetine blocks the uptake of serotonin into human platelets. In vitro studies in animals also suggest that paroxetine is a potent and highly selective inhibitor of neuronal serotonin reuptake and has only very weak effects on norepinephrine and dopamine neuronal reuptake. In vitro radioligand binding studies indicate that paroxetine has little affinity for muscarinic, alpha1, alpha2, beta adrenergic, dopamine (D2), 5-HT1, 5 HT2 and histamine (H1)-receptors; antagonism of muscarinic, histaminergic and alpha1-adrenergic receptors has been associated with various anticholinergic, sedative and cardiovascular effects for other psychotropic drugs. Because the relative potencies of paroxetine’s major metabolites are at most 1/50 of the parent compound, they are essentially inactive.
Paroxétine Evolugen treats the symptoms of depression, various anxiety disorders, posttraumatic stress disorder, obsessive-compulsive disorder, and the vasomotor symptoms of menopause via the inhibition of serotonin reuptake. The onset of action of paroxetine is reported to be approximately 6 weeks.
Due its serotonergic activity, paroxetine, like other SSRI drugs, may potentiate serotonin syndrome. This risk is especially high when monoamine oxidase (MAO) inhibitors are given within 2 weeks of paroxetine administration. Upon cessation of MAO inhibitors, a 2-week interval before paroxetine administration is recommended. Do not coadminister these agents.

- Social Anxiety Disorder
- Generalized Anxiety Disorder
- Posttraumatic Stress Disorder.
Paroxétine Evolugen is also used to associated treatment for these conditions: Generalized Anxiety Disorder (GAD), Irritable Bowel Syndrome (IBS), Major Depressive Disorder (MDD), Obsessive Compulsive Disorder (OCD), Panic Disorder, Post Traumatic Stress Disorder (PTSD), Premature Ejaculation, Premenstrual Dysphoric Disorder, Social Anxiety Disorder (SAD), Vasomotor Symptoms Associated With Menopause
How Paroxétine Evolugen works
Paroxétine Evolugen enhances serotonergic activity via the inhibition presynaptic reuptake of serotonin by the serotonin (SERT) receptor. This inhibition raises the level of serotonin in the synaptic cleft, relieving various symptoms. This drug has been demonstrated to be a stronger inhibitor of serotonin reuptake than other members of the same drug class, including Citalopram, Fluoxetine, and Fluvoxamine. The mechanism of action of paroxetine in relieving the vasomotor symptoms of menopause is unknown, according to the Brisdelle prescribing information, but may occur due to its effects on thermoregulation.
Paroxétine Evolugen shows a clinically insignificant affinity for adrenergic alpha-1 and alpha-2 receptors and β-adrenergic receptors, dopamine D1 and D2 receptors, histamine H1 receptors and serotonin 5-HT1A, 5-HT2A and 5-HT2C receptors. This drug shows some affinity for muscarinic cholinergic receptors and 5-H2B receptors. The delayed onset of paroxetine therapeutic effects may be explained by the initial paroxetine actions on the 5-HT neurons. In rats, paroxetine activates 5-HT1A receptors when it is first administered, inhibiting the stimulation of the 5-HT neurons and subsequent release of serotonin at the synaptic cleft.

Common manifestations in a paroxetine overdose include fatigue, fever, insomnia hypertension, tachycardia, nausea, vomiting, somnolence, tremor, dizziness, agitation, confusion, anxious symptoms, headache, insomnia, hyperhidrosis, dilated pupils, seizures, paresthesia, serotonin syndrome, involuntary muscle contraction, and change in mental status. It should be noted that in some cases, patients may have consumed alcohol in addition to taking an overdose of paroxetine. Some of these symptoms may also be seen with clinical use. There is no specific antidote to an overdose of paroxetine.
Precaution
Cardiac conditions: Paroxétine Evolugen does not produce clinically significant changes in blood pressure, heart rate and ECG. Nevertheless, as with all psychoactive drugs, caution is advised when treating patients with cardiac conditions.
Epilepsy: As with other antidepressants, Paroxétine Evolugen should be used with caution in-patients with epilepsy.
Seizures: Overall, the incidence of seizures is < 0.1% in patients treated with Paroxétine Evolugen. Paroxétine Evolugen should be discontinued in any patient who develops seizures.
ECT: There is little clinical experience of concurrent administration of Paroxétine Evolugen with ECT.
Ability to drive/use machines: Clinical experience has shown that therapy with Paroxétine Evolugen is not associated with impairment of cognitive or psychomotor function. However, as with all psychoactive drugs, patients should be cautioned about their ability to drive a car and operate machinery.
Discontinuation of Treatment with Paroxétine Evolugen: Recent clinical trials supporting the various approved indications of Paroxétine Evolugen employed a taper phase regimen, rather than an abrupt discontinuation of treatment. The taper phase regimen used in GAD and PTSD clinical trials involved an incremental decrease in the daily dose by 10 mg/day at weekly intervals. When a daily dose of 20 mg/day was reached, patients were continued on this dose for 1 week before treatment was stopped.
Interaction
Food/antacids: The absorption and pharmacokinetics of Paroxétine Evolugen are not affected by food or antacids.
Tryptophan: As with other 5-HT re uptake inhibitors, animal studies indicate that an interaction between Paroxétine Evolugen and Tryptophan may occur, resulting in a ‘serotonin syndrome’ suggested by a combination of agitation, restlessness and gastrointestinal symptoms including diarrhoea.
Drug metabolizing enzyme inducers /inhibitors: The metabolism and pharmacokinetics of Paroxétine Evolugen may be affected by drugs, which induce or inhibit hepatic drug metabolizing enzymes. When Paroxétine Evolugen is to be coadministered with a known drug metabolizing inhibitor, consideration should be given to using doses at the lower end of the range. No initial dosage adjustment of Paroxétine Evolugen is considered necessary when it is to be co-administered with known drug metabolizing enzyme inducers. Any subsequent dosage adjustment should be guided by clinical effect (tolerabilityand efficacy).
Alcohol: Although Paroxétine Evolugen does not increase the impairment of mental and motor skill caused by alcohol, the concomitant use of Paroxétine Evolugen and alcohol in depressed patients is not advised.
Haloperidol/amylobarbitone/oxazepam: Experience in a limited number of healthy subjects has shown that Paroxétine Evolugen did not increase the sedation and drowsiness associated with haloperidol, amylobarbitone or oxazepam when given in combination.
MAOls: As with other 5-HT re uptake inhibitors, animal studies indicate that an interaction between Paroxétine Evolugen and monoamine oxidase (MAO) inhibitors may occur.
Lithium: Since there is little clinical experience, and there have been reports of interaction of lithium with other 5-HT re-uptake inhibitors, the concurrent administration of Paroxétine Evolugen and lithium should be undertaken with caution.
Lithium levels should be monitored. Phenytoin / anticonvulsants: Co-administration of Paroxétine Evolugen and phenytoin is associated with decreased plasma concentrations of Paroxétine Evolugen and increased adverse experiences. Co-administration of Paroxétine Evolugen with other anticonvulsants may also be associated with an increased incidence of adverse experiences.
Warfarin: Preliminary data suggest that there may be a pharmacodynamic interaction between Paroxétine Evolugen and warfarin, which may result in increased bleeding in the presence of unaltered prothrombin times. Paroxétine Evolugen should therefore be administered with great caution to patients receiving oral anticoagulants.
Food Interaction
- Avoid alcohol.
- Take with or without food. Food does not significantly affect absorption.
[Moderate] GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents.
Use in combination may result in additive central nervous system depression and
MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol.
Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

Paroxétine Evolugen Disease Interaction
Major: depressionModerate: bone fractures, renal dysfunction, hyponatremia, glaucoma, liver disease, mania, platelet function, seizure disorders, SIADHMinor: weight loss
Volume of Distribution
Paroxétine Evolugen has a large volume of distribution and is found throughout the body, including in the central nervous system. Only 1% of the drug is found in the plasma. Paroxétine Evolugen is found in the breast milk at concentrations similar to the concentrations found in plasma.
Elimination Route
Paroxétine Evolugen is readily absorbed from the gastrointestinal tract. Due to the first-pass metabolism, the bioavailability ranges from 30-60%. Cmax is attained 2 to 8 hours after an oral dose. Mean Tmax is 4.3 hours in healthy patients. The steady-state concentration of paroxetine is achieved within 7 to 14 days of oral therapy. In a pharmacokinetic study, AUC in healthy patients was 574 ng·h/mL and 1053 ng·h/mL in those with moderate renal impairment.
Half Life
The mean elimination half-life of paroxetine is about 21 hours. In healthy young subjects, mean elimination half-life was found to be 17.3 hours.
Clearance
The apparent oral clearance of paroxetine is 167 L/h. The clearance of paroxetine in patients with renal failure is significantly lower and dose adjustment may be required, despite the fact that it is mainly cleared by the liver. Dose adjustments may be required in hepatic impairment.
Elimination Route
About 2/3 of a single paroxetine dose is found to be excreted in the urine and the remainder is found to be excreted in feces. Almost all of the dose is eliminated as metabolites; 3% is found to be excreted as unchanged paroxetine. About 64% of a 30 mg oral dose was found excreted in the urine, with 2% as the parent drug and 62% appearing as metabolites. Approximately 36% of the dose was found to be eliminated in the feces primarily as metabolites and less than 1% as the parent compound.
Pregnancy & Breastfeeding use
This drug should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Labor and Delivery: The effect of Paroxétine Evolugen on labor and delivery in humans is unknown.
Nursing Mothers: Like many other drugs, Paroxétine Evolugen is secreted in human milk, and caution should be exercised when Paroxétine Evolugen hydrochloride is administered to a nursing woman.
Contraindication
Concomitant use in patients taking either monoamine oxidase inhibitors (MAOIs) or thioridazine is contraindicated. This is contraindicated in patients with a hypersensitivity to Paroxétine Evolugen.
