Overview of Selectra (Escitalopram)

Quick Facts

Property Description
Active ingredient Escitalopram (typically as the oxalate salt)
Form Film-coated tablets, Oral solution
Pharmacological class Selective Serotonin Reuptake Inhibitor (SSRI)
Common use General improvement of mood stability and reduction of anxiety
Origin Synthetic, Enantiomerically pure compound

What Type of Medicine is Selectra (Escitalopram)?

Selectra is a prescription-only medicine containing the active compound Escitalopram, which is categorized as an antidepressant and a psychotropic agent. The medication belongs specifically to the Selective Serotonin Reuptake Inhibitor (SSRI) class. This classification reflects that the compound operates by selectively targeting the reuptake mechanism of a specific neurotransmitter. Escitalopram is unique among some related drugs because it is the S-enantiomer, an enantiomerically pure compound representing the single therapeutically active isomer.

Escitalopram: Composition, Form, and Origin

The product is a single active ingredient product, relying entirely on the synthesized compound Escitalopram, often formulated as the oxalate salt. Escitalopram is a synthetic chemical entity developed for oral use and is available to patients in the form of film-coated tablets and an oral solution. These diverse dosage forms facilitate flexible administration and delivery of the active substance to the systemic circulation. The brand Selectra is recognized across multiple markets for its application in adult and adolescent patient groups.

What is the General Purpose of Selectra (Escitalopram)?

The general purpose of Selectra is to promote improved mood stability and reduce pervasive feelings of excessive anxiety or emotional tension. Its action, called serotonin reuptake inhibition, results in higher concentrations of serotonin available for communication between nerve cells. This medication is used in managing symptoms requiring a rebalancing of these chemical messengers. This means the drug provides a foundation for helping to normalize the signaling pathways that influence a person's emotional state and overall psychological well-being.

What should I know about interactions with other medicines?

Interactions with other medicines and products

Contraindicated Combinations

Escitalopram must not be used concurrently with Monoamine Oxidase Inhibitors (MAOIs) intended for psychiatric treatment. This includes a washout period, requiring at least 14 days between discontinuing one medicine and starting the other, due to the risk of Serotonin Syndrome. This risk also applies to other MAOIs such as Linezolid (an antibiotic) and intravenous Methylene Blue. Concomitant use with the antipsychotic medicine Pimozide is also contraindicated due to the risk of heart rhythm abnormalities, specifically QT interval prolongation.

Caution Required

  • Serotonergic Agents: Use with caution, and generally avoid, combinations with other medicines that increase serotonin levels, including certain triptans, Tricyclic Antidepressants, Lithium, Tramadol, Buspirone, and the herbal supplement St. John's Wort, as this significantly increases the risk of Serotonin Syndrome.
  • Drugs that Affect Hemostasis: Increased risk of abnormal bleeding exists when escitalopram is used with medicines that interfere with blood clotting, such as NSAIDs (e.g., ibuprofen, naproxen), Aspirin, and Warfarin. Monitoring is necessary when combining these agents.
  • QT Prolonging Agents: Co-administration with other medicines known to prolong the QT interval (e.g., certain antipsychotics and antiarrhythmics) is not recommended due to additive cardiac risk.

Pharmacokinetic Interactions

Escitalopram is a weak inhibitor of the CYP2D6 enzyme, which may lead to increased plasma concentrations of medicines metabolized by this pathway, such as Desipramine and Metoprolol. Conversely, inhibitors of the CYP2C19 enzyme (e.g., Omeprazole) can increase the body's exposure to escitalopram.

Mechanism of Action

Highly Selective Blockade of the Serotonin Transporter

Escitalopram's mechanism begins with the selective inhibition of the Serotonin Transporter (SERT), a protein pump responsible for clearing the neurotransmitter Serotonin (5 -HT) from the synapse. The compound is the S-enantiomer, binding to both the primary site and an allosteric site on the transporter, which enhances the inhibitory effect. This immediate molecular action causes a rapid and sustained rise in the concentration of Serotonin available for communication between nerve cells.


Delayed Process of Neuronal Adaptation

The sustained high levels of synaptic Serotonin initiate a crucial neuronal adaptation process, involving the slow desensitization and downregulation of inhibitory Serotonin autoreceptors. This cellular change is the physiological constraint that explains the delay between initial exposure and the full establishment of the drug's sustained effect. The adaptation allows the chronic Serotonin elevation to finally translate into enhanced postsynaptic signaling and sustained activity changes in the CNS regulatory pathways.


Sustained Alteration of Central Nervous System Tone

The complete mechanistic cascade—from selective molecular blockade to delayed neuronal adaptation—results in a sustained alteration of Serotonergic tone within the Central Nervous System (CNS). This process alters and sustains changes within the affected CNS pathways. The mechanism's high specificity results in a focused modulation of Serotonin-dependent pathways.

Recent Clinical Evidence

Selectra (Escitalopram): Recent Clinical Evidence

This section summarizes clinical research evaluating escitalopram, a highly selective serotonin reuptake inhibitor (SSRI), for its approved uses.


Clinical Efficacy and Study Design

Escitalopram has been studied across numerous randomized, placebo-controlled trials for conditions including Major Depressive Disorder (MDD) and Generalized Anxiety Disorder (GAD). For the acute treatment of GAD in adults, studies comparing escitalopram to placebo reported a statistically significant difference in the mean change from baseline on the Hamilton Rating Scale for Anxiety (HAMA) score at the study endpoint. Findings suggesting a difference in outcome were observed as early as Week 1 of treatment in some trials.

Research has also investigated the long-term use of escitalopram. Maintenance treatment studies in adult patients with MDD who initially responded to treatment demonstrated that continuing escitalopram was associated with a statistically relevant benefit in preventing relapse or recurrence of depressive episodes.


Safety and Tolerability Profile

The tolerability of escitalopram is typically assessed using discontinuation rates due to adverse events and the incidence of specific side effects. The most frequently reported adverse events across clinical trials, observed at a rate of 5% or more and at least twice the rate of placebo, include nausea, somnolence, insomnia, and sexual dysfunction (specifically ejaculation disorder and decreased libido).

  • Cardiac Risk: Studies have noted that escitalopram is associated with a mild, dose-dependent prolongation of the QTc interval. However, the observed risk of related serious heart rhythm disturbances (such as Torsades de Pointes) has been reported as very low.
  • Other Risks: Monitoring for the emergence of symptoms of Serotonin Syndrome is standard, particularly when the drug is co-administered with other serotonergic agents. Trials also noted the potential for hyponatremia (low sodium levels), especially within the initial weeks of beginning treatment.
