Usage
This drug combination is prescribed for anxiety disorders, panic disorders, and insomnia. It is classified as a sedative-hypnotic (Etizolam) and antidepressant (Paroxetine). Etizolam enhances the effect of the inhibitory neurotransmitter GABA, leading to a calming effect. Paroxetine, an SSRI, increases serotonin levels in the brain, which helps improve mood and reduce anxiety.
Alternate Names
Etizolam is sometimes referred to as Depas, Etilaam, Sedekopan while Paroxetine is also known as Paxil, Seroxat, and Aropax. Etizolam + Paroxetine is marketed under brand names like Etizola P.
How It Works
Etizolam: This drug binds to the benzodiazepine site on the GABA-A receptor, increasing the inhibitory effects of GABA, leading to sedation, muscle relaxation, and anti-anxiety effects. It’s metabolized in the liver and eliminated primarily through renal excretion.
Paroxetine: This SSRI inhibits the reuptake of serotonin in the synaptic cleft, increasing its concentration and enhancing serotonergic neurotransmission. Paroxetine affects mood, sleep, and anxiety. It’s metabolized primarily in the liver by CYP2D6 enzyme and eliminated via renal excretion.
Dosage
The dosage for this combination varies depending on the individual and the severity of the condition. It’s crucial to follow the doctor’s instructions.
Standard Dosage
Adults:
A common starting dose is Paroxetine 12.5mg and Etizolam 0.5mg once daily, usually in the morning with food. The dosage can be adjusted upwards by your doctor as needed, usually not exceeding Paroxetine 50mg/day or Etizolam 1mg/day.
Children:
This combination is generally not recommended for children.
Special Cases:
- Elderly Patients: Lower starting doses of both medications are recommended due to age-related changes in drug metabolism and clearance. Careful titration is necessary.
- Patients with Renal Impairment: Dosage adjustments, especially for Paroxetine, may be required depending on the degree of impairment.
- Patients with Hepatic Dysfunction: Lower starting doses and cautious monitoring are recommended for both drugs.
- Patients with Comorbid Conditions: Close monitoring and dosage adjustment may be required depending upon specific comorbidities.
Clinical Use Cases
This combination is not typically used in clinical settings like intubation, surgical procedures, mechanical ventilation, ICU, or emergency situations.
Dosage Adjustments
Dosage must be individualized based on patient response, renal/hepatic function, and drug interactions. Genetic polymorphisms affecting CYP2D6 activity can influence Paroxetine metabolism, necessitating dose adjustments.
Side Effects
Common Side Effects
Nausea, diarrhea, vomiting, dizziness, drowsiness, fatigue, decreased libido, dry mouth, insomnia, confusion, uncoordinated body movements, and memory impairment.
Rare but Serious Side Effects
Serotonin syndrome (high fever, muscle rigidity, seizures, coma), severe allergic reactions, bleeding problems, increased risk of suicidal thoughts (especially in young adults), mania, and hyponatremia.
Long-Term Effects
Withdrawal symptoms (anxiety, irritability, insomnia) upon abrupt discontinuation, sexual dysfunction, and potential dependence with Etizolam.
Adverse Drug Reactions (ADR)
Severe allergic reactions, seizures, serotonin syndrome, and paradoxical reactions (increased anxiety, agitation).
Contraindications
Hypersensitivity to either drug, concomitant use of MAOIs, pimozide, or thioridazine. Use with caution in patients with glaucoma, seizure disorders, bipolar disorder, bleeding disorders, liver or kidney disease.
Drug Interactions
Alcohol, CNS depressants (opioids, benzodiazepines, barbiturates), other antidepressants (SSRIs, SNRIs, TCAs), antipsychotics, anticoagulants (warfarin), anticonvulsants, CYP2D6 inhibitors (fluoxetine, paroxetine), CYP3A4 inhibitors, and some antifungal medications.
Pregnancy and Breastfeeding
Paroxetine is generally considered one of the safer antidepressants during pregnancy but has been associated with a slight increase in the risk of some heart defects. It is excreted in breast milk. Etizolam’s safety during pregnancy and breastfeeding is unknown. Consult with a specialist.
Drug Profile Summary
- Mechanism of Action: Etizolam enhances GABAergic activity; Paroxetine inhibits serotonin reuptake.
- Side Effects: Nausea, dizziness, drowsiness, sexual dysfunction, potential for dependence.
- Contraindications: Hypersensitivity, concomitant MAOI use.
- Drug Interactions: CNS depressants, other antidepressants, alcohol.
- Pregnancy & Breastfeeding: Paroxetine relatively safe; Etizolam’s safety unknown.
- Dosage: Varies; typically starts low and titrated upwards.
- Monitoring Parameters: Mood, anxiety levels, side effects, liver function, renal function (especially with prolonged use or in elderly patients), and complete blood count in case of any indication of bleeding.
Popular Combinations
This particular combination is not a common or recommended practice. Typically, benzodiazepines like Etizolam are used for short-term anxiety management while Paroxetine alone is used for long-term management.
Precautions
Pre-existing medical conditions should be evaluated before starting therapy. Caution is advised in elderly patients and those with liver or kidney dysfunction. Patients should be monitored for suicidal thoughts and behaviors. Avoid alcohol.

A: While used for anxiety and insomnia in some regions, this specific combination isn’t generally recommended due to the risk of dependence and other potential side effects.
Q3: What are the major side effects?
A: Common side effects include nausea, dizziness, drowsiness, and sexual dysfunction. Serious side effects include serotonin syndrome, increased suicidal ideation, and withdrawal symptoms.
Q4: Are there any specific contraindications?
A: Yes. Contraindications include hypersensitivity to the drugs and concomitant MAOI use.
Q5: How does this combination work?
