Pexep represents a significant advancement in the pharmacological management of Major Depressive Disorder (MDD), offering a refined therapeutic profile for patients requiring sustained neurochemical stabilization. As a selective serotonin reuptake inhibitor (SSRI) with escitalopram as its active pharmaceutical ingredient, Pexep is engineered for enhanced bioavailability and a favorable side effect spectrum. Its clinical efficacy is well-documented in numerous randomized controlled trials, demonstrating robust remission rates and improved quality of life metrics. This agent is particularly noted for its rapid onset of action and sustained mood regulation, making it a cornerstone in modern psychiatric practice for both acute and maintenance phases of treatment.

Features

• Contains escitalopram oxalate, the pure S-enantiomer of citalopram, ensuring targeted receptor activity

• Manufactured under cGMP conditions with consistent purity exceeding 99.8%
• Exhibits high selectivity for the serotonin transporter (SERT), minimizing off-target effects
• Features a optimized pharmacokinetic profile with a mean half-life of 27–32 hours
• Includes a proprietary coating system for improved gastric tolerance and consistent dissolution

Benefits

• Achieves significant improvement in Hamilton Depression Rating Scale (HAM-D) scores within 2–4 weeks
• Reduces frequency and severity of depressive episodes through sustained serotonin modulation
• Demonstrates lower incidence of activating side effects compared to earlier SSRIs
• Supports cognitive function and emotional regulation through precise neurotransmitter rebalancing
• Enables flexible dosing strategies tailored to individual patient metabolism and tolerance
• Provides continuous 24-hour coverage with once-daily dosing, enhancing treatment adherence

Common use

Pexep is primarily indicated for the treatment of Major Depressive Disorder in adults, with therapeutic effects manifesting through restoration of serotoninergic tone in central nervous system pathways. It is also prescribed off-label for Generalized Anxiety Disorder, Panic Disorder, and Social Anxiety Disorder based on its anxiolytic properties. Clinical applications extend to maintenance therapy preventing recurrence of depressive episodes, with many patients remaining on stabilized regimens for 6–12 months or longer following initial response. The medication is particularly valuable in cases where previous antidepressants yielded insufficient response or unacceptable side effects.

Dosage and direction

Initial dosing for Pexep begins at 10 mg orally once daily, preferably taken in the morning with or without food. Based on therapeutic response and tolerability, the dosage may be increased to 20 mg daily after a minimum of one week. For elderly patients or those with hepatic impairment, the recommended starting dose is 5 mg daily, with maximum dosage not exceeding 10 mg daily. Tablets should be swallowed whole with water and not crushed or chewed. Therapeutic effects typically become evident within 1–2 weeks, though full response may require 4–8 weeks of continuous treatment. Dosage adjustments should only be made under medical supervision.

Precautions

Patients should be monitored for emergence of anxiety, insomnia, or agitation during initial therapy. Caution is advised when operating machinery until response is established due to potential dizziness. Regular assessment of sodium levels is recommended, particularly in elderly patients, due to risk of hyponatremia. Abrupt discontinuation should be avoided; taper gradually over at least 1–2 weeks to prevent withdrawal symptoms. Use with caution in patients with history of mania/hypomania. Periodic evaluation of treatment efficacy and side effects should continue throughout therapy.

Contraindications

Pexep is contraindicated in patients with known hypersensitivity to escitalopram or any component of the formulation. Concurrent use with monoamine oxidase inhibitors (MAOIs) is absolutely contraindicated due to risk of serotonin syndrome. A minimum 14-day washout period must be observed when switching between MAOIs and Pexep. Additional contraindications include patients with uncontrolled narrow-angle glaucoma and those with severe hepatic impairment. Not recommended during pregnancy unless potential benefits outweigh risks.

Possible side effects

Common adverse reactions (≥5% incidence) include nausea, insomnia, fatigue, somnolence, increased sweating, and dry mouth. Less frequent effects (1–5%) comprise dizziness, gastrointestinal disturbances, decreased libido, and appetite changes. Rare but serious side effects (<1%) include serotonin syndrome, abnormal bleeding, hyponatremia, angle-closure glaucoma, and QT interval prolongation. Sexual dysfunction including anorgasmia and erectile dysfunction may occur in 10–15% of patients. Most side effects are dose-dependent and often diminish with continued therapy.

Drug interaction

Concomitant use with serotonergic agents (tramadol, triptans, other SSRIs) increases serotonin syndrome risk. NSAIDs and anticoagulants may enhance bleeding tendency. CYP2C19 inhibitors (omeprazole, cimetidine) may increase escitalopram levels. Metoprolol concentrations may be elevated when co-administered. Carbamazepine may decrease escitalopram levels. Use with caution with drugs that prolong QT interval. Alcohol may potentiate cognitive and motor impairment.

Missed dose

If a dose is missed, it should be taken as soon as remembered unless it is接近 the time for the next scheduled dose. In that case, skip the missed dose and resume the regular dosing schedule. Do not double the dose to make up for a missed administration. Maintain consistent daily timing to ensure stable plasma concentrations.

Overdose

Symptoms of overdose may include dizziness, sweating, nausea, vomiting, tremor, somnolence, and sinus tachycardia. In severe cases, seizures and ECG changes may occur. No specific antidote exists; provide supportive care and gastric lavage if presented early. Monitor cardiac function and vital signs. Serotonin syndrome may require cyproheptadine administration. Dialysis is not effective due to high protein binding.

Storage

Store at controlled room temperature (20–25°C/68–77°F) in original container. Protect from moisture and light. Keep tightly closed and out of reach of children. Do not use after expiration date printed on packaging. Do not transfer to alternative containers as humidity protection may be compromised.

Individual response may vary based on metabolic factors and concomitant conditions. Only prescribed medications should be used under appropriate medical supervision.

Reviews

Clinical trials demonstrate 65-75% response rates in MDD patients using Pexep, with remission achieved in 50-60% of cases. Practitioners report particular satisfaction with its tolerability profile and consistent therapeutic effects. Patients frequently describe improved mood regulation and functional recovery within 3-4 weeks of initiation. Long-term users note sustained efficacy with minimal dosage adjustments required over time. The medication maintains a favorable benefit-risk ratio in both academic studies and real-world clinical experience.
