Overview of Циталопрам

What is Citalopram? An Overview

Property Description
Active Ingredient Citalopram Hydrobromide
Form Oral Tablet or Solution
Pharmacological Class Selective Serotonin Reuptake Inhibitor (SSRI)
Origin Synthetic Compound
General Purpose Stabilizing Mood and Emotional Balance

What Type of Medicine is Citalopram?

Citalopram is a widely used prescription medication that belongs to the class of antidepressants known as Selective Serotonin Reuptake Inhibitors (SSRIs).

It is clinically recognized for its high selectivity, primarily targeting the reabsorption of serotonin, a crucial brain chemical that helps regulate mood. This high selectivity profile is a distinguishing feature, making it an option when targeted support for emotional stability is needed. The drug's action increases the amount of available serotonin in the space between nerve cells, providing a foundational adjustment to brain chemistry. A typical scenario involves using the medication to help a patient regain emotional stability and manage persistent, debilitating low mood.


Composition and General Purpose

Citalopram is a fully synthetic chemical compound, manufactured in a controlled setting, ensuring a precise and standardized dose of the active ingredient, Citalopram Hydrobromide.

This synthetic origin guarantees reliable consistency across the available dosage forms, which include both an oral tablet and a liquid solution. The medication's core purpose is to re-regulate the brain's emotional circuitry. While chemically related to Escitalopram, Citalopram contains a mixture of two mirror-image molecules (racemate), and it is a safe and effective treatment choice. The ultimate goal is to provide a solid foundation for sustained improvement in overall emotional well-being and daily function.

What side effects are possible with Циталопрам?

Possible Side Effects and Safety Information

The safety profile of Citalopram is established through official regulatory documentation, classifying potential effects based on frequency and impact on organ systems. The most Very Common adverse reactions, defined as affecting 1 in 10 individuals or more, include headache, nausea, dry mouth, somnolence, insomnia, and increased sweating (hyperhidrosis). Common effects, reported in 1 to 10 in 100 people, often involve the gastrointestinal and nervous systems, such as diarrhea, vomiting, fatigue, and decreased libido.


Regulatory Safety Constraints

Official labels define several serious adverse reactions. These include the risk of QT Prolongation, a dose-dependent effect on heart rhythm, and Serotonin Syndrome, a rare but potentially fatal condition, particularly when Citalopram is combined with other serotonergic medicines. A Boxed Warning highlights the increased risk of suicidal thoughts and behaviors in children, adolescents, and young adults (up to age 24), primarily during the initial treatment and dose adjustments.


Population and Time-Related Safety

Population-specific constraints are formally documented: a lower maximum recommended dose is required for older adults and individuals with hepatic impairment due to expected higher drug exposure and increased risk of QT prolongation. Safety and effectiveness are not established in pediatric patients. Time-related patterns note that psychiatric symptoms, like agitation or akathisia (psychomotor restlessness), are more likely to occur early in the course of therapy. Citalopram is strictly prohibited (contraindicated) for use with Monoamine Oxidase Inhibitors (MAOIs) or Pimozide.

Overdose and Emergency Response

Overdose and When to Seek Help

The following information details the documented manifestations and mandatory emergency actions for Citalopram overdose, based strictly on government regulatory labeling.

Documented Overdose Manifestations

Official documents indicate that an overdose may present with a range of symptoms, including central nervous system (CNS) effects such as drowsiness (somnolence), tremor, agitation, and seizures.

Cardiovascular effects are also documented, including sinus tachycardia (rapid heart rate), hypotension, and, critically, QTc prolongation (an ECG abnormality). Gastrointestinal effects like nausea and vomiting may also occur. Severe overdose can lead to coma, Serotonin Syndrome, and potentially fatal arrhythmias such as Torsade de Pointes.

Mandatory Emergency Actions

The most important action is to seek immediate medical attention for any suspected overdose. Emergency services should be contacted immediately if the person has experienced a seizure, has trouble breathing, or has become unresponsive.

No specific antidote is known for Citalopram overdose, meaning treatment is strictly symptomatic and supportive. Due to the documented risk of QTc prolongation, continuous cardiac monitoring and correction of electrolyte abnormalities (like hypokalemia) are required management measures in a medical setting.

Therapeutic Uses of Циталопрам

Citalopram is primarily used across domains involving distressing emotional and mood symptoms. The medication is commonly used to help manage clinical conditions like Major Depressive Disorder (MDD) in adults, though its therapeutic scope is considered relevant for related anxiety conditions in clinical practice. The medication helps ease the overall burden of symptoms, assisting with maintaining functional stability.

Supporting Core Emotional Stability and Low Mood

The medication is commonly used to help manage Major Depressive Disorder and conditions marked by a persistent mood dysregulation. It is used to help address the core symptoms of depression, such as chronic sadness, hopelessness, and feelings of worthlessness, and may assist in supporting emotional balance and general well-being.

Easing Excessive Anxiety and Panic Symptoms

Citalopram is applied in clinical settings that involve acute or disruptive symptom patterns characteristic of anxiety-related conditions, including Panic Disorder. It is relevant for easing the intensity and frequency of sudden fear attacks and pervasive worry, which supports patients during difficult episodes by easing generalized distress and functional strain.

Eligibility and Restrictions for Use

Who Can and Cannot Use Citalopram?

This section defines the official population-eligibility rules for Citalopram, strictly based on government regulatory documentation. Citalopram is generally approved for adults 18 years and older.


Absolute Contraindications

Official labeling mandates that Citalopram must not be used by the following groups due to the risk of serious adverse reactions:

  • Patients currently taking, or within 14 days of discontinuing, a Monoamine Oxidase Inhibitor (MAOI), including Linezolid.
  • Patients taking Pimozide or other medications known to prolong the QT interval.
  • Patients with a known history of QT interval prolongation or Congenital Long QT Syndrome.
  • Patients with known Hypersensitivity to the active ingredient or any excipients.

Conditional and Restricted Use

Eligibility is conditional for certain populations, often requiring a restricted maximum dose:

  • Older Adults (Geriatric Patients) and patients with Hepatic Impairment (liver disease) have a restricted maximum daily limit of 20 mg.
  • Children and Adolescents (under 18 years) are not approved for use, as safety and efficacy have not been established in this age group.
  • Pregnancy and Lactation require careful consideration; use during late pregnancy may be associated with neonatal issues, and Citalopram is present in breast milk.

These official rules clarify who is eligible and who is formally excluded from treatment.

What should I know about interactions with other medicines?

Citalopram Interactions with other medicines and products

Interactions with Citalopram are primarily categorized by additive pharmacodynamic effects or pharmacokinetic alteration of its clearance.


Contraindicated Combinations

Certain combinations are officially restricted due to high risk:

  • Monoamine Oxidase Inhibitors (MAOIs): Concurrent use is contraindicated due to the serious risk of Serotonin Syndrome. A washout period of at least 14 days is required when switching between Citalopram and an MAOI.
  • Medicinal Products that Prolong the QT Interval: Co-administration with drugs known to prolong the QT interval, such as Pimozide, is contraindicated due to the risk of serious cardiac arrhythmias (e.g., Torsade de Pointes).

Combinations Requiring Caution and Monitoring

  • Serotonergic Agents: Using Citalopram with other serotonergic agents (e.g., triptans, other SSRIs, SNRIs) requires close monitoring for signs of Serotonin Syndrome.
  • Agents that Affect Hemostasis: Co-administration with drugs like NSAIDs, aspirin, or anticoagulants (e.g., warfarin) increases the risk of bleeding due to Citalopram's effect on platelet function.
  • CYP2C19 Inhibitors: Potent inhibitors of the enzyme CYP2C19 (e.g., Cimetidine) can decrease Citalopram clearance. This pharmacokinetic interaction requires caution, and a maximum dose reduction may be necessary to mitigate the risk of dose-dependent cardiac effects.

Mechanism of Action

How Циталопрам Works

This section explains the biological mechanism of action and the resulting physiological effects of the drug.


Selective Blocking of the Serotonin Transporter

Циталопрам acts as a selective inhibitor by binding to the Serotonin Transporter (SERT), a protein located on the presynaptic neuronal membrane that normally removes the chemical messenger serotonin from the synaptic space. By blocking this reuptake process, the drug immediately increases the concentration and duration of serotonin at the synapse, which initiates heightened activation of postsynaptic receptors.


Long-Term Regulation of Neural Circuitry

The sustained elevation of serotonin activity triggers adaptive changes in the brain's circuitry—a process known as neuroplasticity. Over weeks, this leads to the adjustment of receptor sensitivity and promotes the remodeling of neuronal connections. This chronic modulation influences activity within the systems regulating emotional state, leading to the resulting adjustment of signaling patterns within circuits governing stress and emotional processing.

Dosage and Administration Information

How to Use Citalopram: Official Administration Guidelines

Citalopram is administered orally (by mouth) once a day, with or without food. The medication should be taken at the same time each day, either in the morning or evening.


Dosing and Schedule

Population Starting Dose Maximum Recommended Daily Dose
Adults (under 60 years) 20 mg once daily 40 mg
Older Adults (60 years and older) 20 mg once daily 20 mg
Patients with Hepatic Impairment 20 mg once daily 20 mg
  • Dose Adjustment: Any increase in dosage must be implemented gradually, with at least a one-week interval between dose adjustments. The maximum dose limit of 40 mg daily (or 20 mg for specific populations) must not be exceeded.
  • Missed Dose: If a dose is missed, the next dose should be taken at the regular time. Do not take two doses to make up for the missed dose.
  • Discontinuation: When stopping the medication, the dosage should be reduced gradually over a period of time to avoid adverse effects. The reduction schedule must be determined by a healthcare provider.

Administration Requirements

  • Tablets: Tablets should be swallowed whole and should not be chewed.
  • Oral Solution: If using the liquid form, shake the bottle well before use and measure the dose accurately using a marked measuring device, such as a medicine cup, oral syringe, or measuring spoon.

These instructions define the standardized procedure for the correct intake, titration, and cessation of the medication.

Recent Clinical Evidence

Research evidence / Overview of studies for Citalopram


Conditions Characterized by Periods of Low Mood and Functional Limitation

Citalopram was studied for conditions marked by functional limitations and cycles of stability and flare-ups, specifically focusing on outcomes related to physical discomfort and patient-reported outcomes describing perceived discomfort. The research examined how symptoms change over defined time intervals, often applied in studies focusing on patient-reported outcomes and reflecting daily functioning or activity level. These investigations were often used in research exploring how symptoms change over time in populations experiencing fluctuating or unstable symptoms.

The studies monitored patterns related to outcomes reflecting daily functioning or activity level, and the findings describe patterns observed in the studies. Research describes that studies report how symptoms evolved in the observed populations, and this evidence describes symptom patterns.

It is important to understand the context of this evidence. Follow-up durations were limited in many of the initial trials, meaning long-term effects are not fully established, and certainty remains low regarding very long-term outcomes. Data for certain groups, such as those with co-occurring medical conditions or those outside of specific age brackets, remain insufficient, and the research is ongoing.

Studies describe patterns observed in the studies, and research provides context but not individual predictions. Findings describe group patterns, not personal outcomes, and research does not determine whether an individual will respond similarly. The results apply only to the populations studied under the specific conditions of the research.


Conditions Associated with Acute or Disruptive Episodes of Anxiety

Citalopram was evaluated in research involving conditions characterized by fluctuating or episodic manifestations, such as those associated with acute or disruptive episodes of anxiety. This research was relevant in trials assessing short-term or episodic symptom patterns, and was used in studies examining symptom intensity or variability. The focus was on outcomes describing episodic or acute changes and outcomes capturing phases of heightened symptom activity.

Studies focusing on episodes where symptoms become more noticeable explored short-term symptom changes. The data show patterns related to outcomes monitoring physiological strain or stress. Research was conducted during periods of increased symptom activity, and Citalopram was observed in those studies. This evidence describes patterns regarding how short-term changes may present in these conditions.

The evidence for this area is limited in some respects, as comparative evidence is lacking for all possible treatment approaches, and sample sizes were modest in some of the initial research. Subgroup findings are uncertain. Therefore, evidence appears to provide insight into short-term changes, but the data are still emerging.

Evidence describes what is known and what is still uncertain about this condition. The study results reflect the specific conditions under which they were conducted, and findings help contextualize how patients reported their experience during the trials.
