Origin Synthetic compound

What Type of Medicine is Relaxol?

Relaxol, which contains the active substance Citalopram, is classified as a Selective Serotonin Reuptake Inhibitor (SSRI), a prominent category of antidepressant agents. This classification reflects its highly focused action within the central nervous system. Citalopram is a synthetic compound that is chemically defined as a racemic bicyclic phthalane derivative, indicating its laboratory-derived origin and specific molecular structure. This compound is clinically recognized for its established efficacy in supporting patients experiencing challenges with mood stability, distinguishing it through its well-characterized pharmacological pathway.


Composition, Active Ingredient, and Forms

The therapeutic effect of this single-ingredient product is delivered by Citalopram hydrobromide (Citalopram HBr), which is the active chemical salt. Relaxol is intended for oral administration and is routinely manufactured in two primary dosage forms: film-coated oral tablets and an oral solution in an aqueous vehicle. The availability of the liquid oral solution is a key feature that facilitates administration for patient groups, such as adults who require fine dosage adjustments or those who have difficulty swallowing tablets.


General Purpose and Mechanism Focus

The general purpose of this medication is to support the stabilization of mood regulation by assisting in the restoration of a beneficial chemical equilibrium in the brain. Citalopram's fundamental action is the inhibition of neuronal reuptake of serotonin (5-HT). By slowing the reabsorption of this key neurotransmitter back into the nerve cells, Citalopram increases the duration and concentration of serotonin available in the central nervous system, thereby promoting a more balanced state of emotional function. This mechanism is one of the most widely studied in modern psychopharmacology, underpinning its reliable role in supporting patients with mood-related difficulties.

What side effects are possible with Relaxol?

Relaxol: Possible side effects and safety information

The safety profile of Relaxol is primarily characterized by effects across the Gastrointestinal, Nervous System, and Hepatobiliary systems, as documented by regulatory bodies.

Adverse Reaction Categories

Classification Examples of Reactions
Most Common Nausea, somnolence, headache, sexual dysfunction (e.g., ejaculatory delay, decreased libido), dizziness, fatigue.
Common to Uncommon Stomach pain, vomiting, diarrhea, loss of appetite, depressed mood, swelling (edema), skin rash, fever, irregular/fast heart beat, sweating.
Rare Severe skin reactions (e.g., Stevens-Johnson syndrome), decreased white blood cell counts, severe hematologic changes.

Serious Safety Considerations and Limitations

Official regulatory documents emphasize the potential for severe, sometimes fatal, liver damage (hepatotoxicity), with the risk significantly increased by exceeding the maximum recommended dose (overdose) or concurrent alcohol consumption.

Another dose-related risk is QT interval prolongation, which can lead to life-threatening heart rhythm abnormalities (Torsades de Pointes). This requires lower maximum doses and careful consideration in populations over 60 years of age or those with pre-existing cardiac or hepatic impairment.

Safety limitations mandate that use is contraindicated in patients with a known hypersensitivity to the drug and is generally not recommended for those with severe hepatic impairment, angle-closure glaucoma, or specific severe cardiac conditions. Caution is advised when operating machinery due to potential dizziness and somnolence.

Overdose and Emergency Response

Overdose and When to Seek Help

The overdose profile for Relaxol (Citalopram) is documented in official prescribing information, outlining specific clinical manifestations and mandated emergency actions.

Documented Clinical Presentations and Severe Outcomes An overdose may be characterized by general systemic effects such as somnolence, dizziness, tremor, nausea, vomiting, confusion, and seizures. However, the most severe manifestations are primarily cardiovascular. Regulatory documentation explicitly lists a risk of dose-dependent QT-prolongation, ventricular tachycardia, and the potentially fatal abnormal heart rhythm, Torsade de Pointes (TdP), particularly with very high exposures. The onset of Serotonin Syndrome is also listed as a life-threatening complication requiring immediate medical intervention. Patients with pre-existing heart conditions or electrolyte imbalances (hypokalemia, hypomagnesemia) are noted to be at an increased risk of severe cardiac toxicity.

Mandatory Emergency Actions The official guidance states that immediate medical attention must be sought in all cases of suspected overdose. It is specifically mandated to contact a healthcare professional immediately if signs of an abnormal heart rate or rhythm, such as dizziness, palpitations, or syncope, are experienced. No specific antidote is known for Citalopram overdose; therefore, management is based on symptomatic and supportive treatment. This standard regulatory procedure includes necessary measures like continuous ECG monitoring and correction of any electrolyte disturbances.

Therapeutic Uses of Relaxol

What Relaxol Treats: Main Uses and Benefits

Relaxol is commonly used to help with symptoms related to depressive illnesses, including Major Depressive Disorder, and is considered relevant for conditions involving heightened symptoms such as panic disorder. This medication is an applicable option for low mood and sometimes for panic attacks. It is primarily relevant for easing distress in clinical scenarios involving acute or disruptive symptom patterns, such as profound low mood, chronic fatigue, sleep disturbances, and intense worry.

The medication supports the handling of distressing manifestations across key domains. It provides supportive relief when symptoms interfere with routine activities, covering the core emotional symptoms, the neurovegetative symptoms, and the anxiety-related manifestations. This support helps ease the overall symptom burden.

This support helps address recurrent or episodic manifestations of intense worry and anxiety, providing supportive relief when symptoms interfere with routine activities and general comfort. This supports general well-being and may contribute to improved day-to-day comfort during symptomatic periods.


Quick Fact: Symptomatic Support

This medication may assist with maintaining a sense of stability by managing symptoms related to systemic imbalance, such as fatigue, changes in appetite, and impaired concentration.

Eligibility and Restrictions for Use

The eligibility for using Relaxol (Citalopram) is strictly defined by regulatory bodies based on age, concurrent medication use, and specific health conditions.

Contraindicated Populations

Use is absolutely prohibited for patients taking Monoamine Oxidase Inhibitors (MAOIs), including linezolid, or within 14 days of stopping an MAOI. It is also contraindicated in patients taking Pimozide or those with a history of congenital long QT syndrome or known hypersensitivity to Citalopram.

Age and Physiological Restrictions

Population Regulatory Status Restriction/Limitation
Adults (18+ years) Approved for use. Standard labeled use.
Older Adults (over 60) Use is restricted. Maximum daily dose is 20 mg due to cardiac risk.
Children/Adolescents Not approved (use not established). Safety and effectiveness have not been established.
Hepatic Impairment Use is restricted. Maximum daily dose is 20 mg (reduced clearance).

Conditional Use

Patients with certain conditions, such as severe renal impairment or those with risk factors for QT prolongation (e.g., uncompensated heart failure, hypokalemia), require caution or their use is not recommended. Regarding Pregnancy and Lactation, use is generally permitted only if the clinical benefit outweighs the potential risk; exposure in the third trimester may be associated with complications like Persistent Pulmonary Hypertension of the Newborn (PPHN).

What should I know about interactions with other medicines?

Relaxol Interactions with other medicines and products

The official interaction profile for Relaxol is structured around substances that pose an additive risk or significantly alter the drug's plasma concentration, as documented by regulatory authorities.

Contraindicated Combinations

Co-administration with several medicinal products is strictly prohibited. This includes Monoamine Oxidase Inhibitors (MAOIs), such as Linezolid, due to the additive risk of Serotonin Syndrome. The concomitant use of Pimozide is also contraindicated, as is the use of other agents that are known to prolong the QT interval (e.g., certain antiarrhythmics and antipsychotics like Thioridazine).

Metabolic and Exposure Constraints

Relaxol is primarily cleared by the liver enzymes CYP2C19 and CYP3A4. Agents that inhibit CYP2C19 (e.g., Cimetidine, Omeprazole) can decrease Citalopram clearance, leading to increased plasma concentrations. This necessitates a dose restriction for CYP2C19 poor metabolizers, patients with hepatic impairment, and elderly patients (over 60 years old).

Pharmacodynamic and Other Interactions

  • Serotonergic Agents: Increased risk of adverse serotonergic effects exists with other serotonergic substances, including Triptans (e.g., Sumatriptan), Tramadol, Lithium, and the herbal product St. John's wort.
  • Hemostasis: Concomitant use with products that affect platelet function or increase bleeding risk (e.g., NSAIDs, Aspirin, Warfarin) is officially associated with an increased risk of abnormal bleeding.

Administration Rules

There is a mandatory separation period: at least 14 days must elapse after discontinuing an MAOI before starting Relaxol, and vice versa. Furthermore, the FDA label advises against the consumption of alcohol while using Citalopram.

Mechanism of Action

Central Nervous System Modulation

Relaxol engages key GABAA and glycine receptors in the central nervous system, particularly within the spinal cord and brain. This action potentiates inhibitory neurotransmission, which regulates overactive neural pathways and influences systemic physiological states.


Inhibition of Signaling Sequences

The drug modulates pathways characterized by overactivation through initiating or suppressing specific signaling sequences. This modification of early molecular steps in the cascade influences the activity of overactive physiological pathways and decreases the effects associated with excessive mediator activity. The compound's interaction with its primary targets alters ion flux across neuronal membranes, leading to hyperpolarization and a subsequent reduction in cellular excitability, thereby shaping the overall profile of neurophysiological responses.

Recent Clinical Evidence

Research Evidence / Overview of Studies for Relaxol


Evidence for Use in Major Depressive Disorder (MDD)

Research explored Relaxol in the context of MDD, a condition characterized by fluctuating or episodic manifestations of symptoms. The core research available for this indication consists of randomized controlled trials (RCTs) and pooled analyses. These studies have examined how Relaxol was associated with changes in depressive symptoms in adult populations experiencing an acute episode of MDD. Research primarily focused on short-term changes in depression severity over four to eight weeks.

However, the follow-up durations were limited in many core studies. There is limited information for long-term outcomes regarding the extended observation of Relaxol and the durability of observed symptom patterns. Comparative evidence is lacking against every other available treatment, meaning direct head-to-head research is not available for all possible drug comparisons.


Evidence for Use in Generalized Anxiety Disorder (GAD)

Research was evaluated in settings involving GAD, a condition where symptoms may vary in intensity. Studies exploring this use were generally fewer in number and often involved smaller populations compared to the research for MDD. These clinical trials monitored outcomes linked to anxiety symptom intensity using specific rating scales.

Research describes patterns related to changes measured during the study period for those diagnosed with GAD. However, because the number of dedicated, high-quality RCTs is limited, the overall evidence quality varies across studies, and certainty remains low for the generalizability of these findings.


What is Still Uncertain About Relaxol Research

Most available research is focused on short-term symptom changes. While this research contributes to the broader evidence landscape, long-term effects are not fully established. Additionally, research has monitored Relaxol in certain subgroups, such as older adults, but sample sizes were modest and evidence for certain groups remains insufficient. The results apply only to the populations studied and the specific conditions under which the trials were conducted.
