Active Ingredient Piracetam (2-oxo-1-pyrrolidine acetamide)
Pharmacological Class Nootropic agent / Cerebroactive drug
Common Use Support of cognitive functions (e.g., memory, concentration)
Origin Synthetic compound
Forms Tablets (film-coated), Solution (oral/intravenous)

What Type of Medicine is Memoral?

Memoral is a synthetic compound containing the active ingredient Piracetam, which is chemically defined as 2-oxo-1-pyrrolidine acetamide. It is formally classified as a nootropic agent and a cerebroactive drug, meaning its primary mechanism influences brain function and cognitive processes. This prescription-only medicine belongs to the Racetam class of compounds. The active ingredient Piracetam affects the physical and chemical properties of cell membranes. This indicates that the medicine has a capability to influence the integrity and function of nerve cell structures. The drug's classification marks it as an agent developed to target and support neuronal activity.


Composition, Forms, and General Purpose

The active ingredient Piracetam is a single-ingredient product, which is supplied in two primary dosage forms: film-coated tablets intended for oral use, and a solution form which permits both oral ingestion and parenteral (intravenous) administration. The availability of both oral and parenteral forms provides flexibility in delivery. Given its classification, the general therapeutic purpose of Memoral is the support of cognitive function, encompassing mental processes such as memory, the ability to maintain concentration, and general learning capacity, a role recognized in several international markets. Piracetam's main effect involves facilitating neuronal plasticity and protecting cells under conditions of reduced oxygen supply. This indicates the medicine works by helping brain cells adapt and maintain function during periods of metabolic stress. Although used in many European countries, it is important to note that Piracetam is an unapproved drug in the United States and is not authorized for any medical or dietary use.

What side effects are possible with Memoral?

Possible Side Effects and Safety Information

The safety profile for Memoral (Piracetam) is based on adverse reactions and classifications documented in official regulatory prescribing information, such as the Summary of Product Characteristics (SmPC).


Officially Documented Adverse Reactions by Frequency

Adverse effects are categorized by the statistical likelihood of occurrence:

Frequency Classification Documented Adverse Reaction Entities
Common (up to 1 in 10 people) Hyperkinesia (increased activity), Nervousness, Weight gain
Uncommon (up to 1 in 100 people) Somnolence (drowsiness), Depression, Asthenia (weakness)
Frequency Not Known Reactions span multiple systems and include Haemorrhagic disorder, Anaphylactoid reaction, Confusion, Agitation, Headache, Insomnia, and various Gastrointestinal (e.g., Nausea, Diarrhoea) and Skin (e.g., Urticaria) effects.

Key Safety Restrictions and Special Populations

Regulatory documents establish several constraints and specific population notes:

  • Contraindications: Memoral is strictly contraindicated in patients with severe renal impairment (creatinine clearance less than 20 ml/minute), Huntington's Chorea, and a history of Cerebral Haemorrhage. It is also contraindicated in cases of known hypersensitivity to piracetam.
  • Bleeding Risk: Caution is advised for patients with severe haemorrhage or underlying disorders of haemostasis due to the documented effects on platelet aggregation.
  • Withdrawal Requirement: Treatment for conditions like cortical myoclonus must be withdrawn gradually to prevent exacerbation of symptoms or seizures.
  • Thyroid Hormones: Concomitant use with thyroid extract (T3 + T4) has been associated with reports of confusion, irritability, and sleep disorder.

Overdose and Emergency Response

Overdose and when to seek help

Official regulatory documentation states that no additional adverse events specifically related to an overdose of the active ingredient, Piracetam, have been formally reported. However, urgent medical attention must be sought immediately in the event of an acute, significant overdosage.

The highest reported single oral overdose involved the intake of 75 g of the substance. The clinical manifestations observed in this specific case were bloody diarrhoea and abdominal pain. Regulatory documents clarify that these specific gastrointestinal symptoms were most likely attributed to the extreme high dose of the excipient sorbitol contained in the formulation, rather than the active ingredient itself.

If an overdose is suspected, clinical assessment and intervention are required. Treatment for overdose is symptomatic and supportive, as no specific antidote for Piracetam is known. Management procedures for acute, significant overdosage may include emptying the stomach by gastric lavage or induction of emesis (vomiting). Advanced supportive care may involve haemodialysis, a procedure which has been documented to achieve an extraction efficiency of approximately 50 to 60% for Piracetam. There are no specific population-based considerations detailed exclusively within the official overdose management sections.

Therapeutic Uses of Memoral

What Memoral Treats: Main Uses and Benefits

Memoral is commonly used in situations involving certain distressing symptoms that interfere with daily functioning, such as symptoms related to systemic imbalance that affect memory, concentration, and learning capacity. It is considered relevant for managing symptoms that interfere with daily comfort, notably vertigo (dizziness) and feelings of disequilibrium, and may assist with managing symptoms of increased neurological or muscular activity, such as in Cortical Myoclonus.

The medication is considered relevant for managing symptoms associated with acute or episodic changes across several conditions, including Cortical Myoclonus, vertigo, Dyslexia, and cognitive decline. This supportive role may assist with maintaining functional stability and helps patients cope more steadily with symptom fluctuations.

“It is commonly used when symptoms create noticeable functional strain, such as post-stroke or post-surgical settings, where short-term symptomatic assistance is needed.”


Quick Fact: Supportive Symptom Management for Involuntary Muscle Jerks Memoral is commonly used when symptoms escalate temporarily and additional symptomatic support is needed, such as in managing symptoms of increased neurological or muscular activity characteristic of Cortical Myoclonus.

Eligibility and Restrictions for Use

Memoral’s eligibility profile is strictly defined by regulatory authorities based on a patient's existing conditions and physiological status.

Absolute Contraindications

Use of Memoral is formally contraindicated for individuals with known hypersensitivity to Piracetam or its components. It is also absolutely prohibited in patients experiencing acute Cerebral Haemorrhage (bleeding in the brain), those diagnosed with Huntington's Chorea, and individuals with End-Stage Renal Disease (ESRD), due to the drug’s elimination profile.

Restricted and Conditional Use

Use is restricted for patients with Mild to Moderate Renal Impairment, who require mandatory dose adjustment based on their renal function. Elderly patients must undergo regular evaluation of their creatinine clearance when on long-term treatment. Special caution is recommended for those with underlying haemostasis disorders or a history of Haemorrhagic Cerebrovascular Accident (CVA).

Specific Population Status

The medicine is generally not recommended for use during pregnancy or breastfeeding; breastfeeding must be discontinued while receiving treatment. In the pediatric population, use is not recommended for general purposes below certain ages, though specific, authorized uses may exist for older children and adolescents.

What should I know about interactions with other medicines?

The official regulatory profile for Memoral (Piracetam) details specific pharmacodynamic and pharmacokinetic interaction constraints.

Documented Interaction Patterns

Anticoagulant and Antiplatelet Agents Co-administration with acenocoumarol is officially documented to result in a pharmacodynamic interaction that significantly decreases platelet aggregation. Regulatory guidance mandates caution when Memoral is used with acenocoumarol or any other agents that affect hemostasis, due to this documented effect on platelet function.

Thyroid Hormones Combination with thyroid extract (T3 + T4) has been associated with reports of confusion, irritability, and sleep disorder, suggesting a potential for reinforced central nervous system effects.

Metabolic and Pharmacokinetic Profile Regulatory documents conclude the drug interaction potential resulting from metabolic pathways is low. This is because the active ingredient is excreted nearly completely via the kidneys as the unchanged drug. Studies have shown that Memoral does not modify the serum levels of common co-administered antiepileptic medicines, including carbamazepine, phenytoin, and valproate.

Population-Dependent Restrictions

Interaction constraints are directly tied to kidney function. The product is contraindicated in patients with severe renal impairment (creatinine clearance of less than 20 ml/min) due to the lack of clearance and risk of accumulation. No dose adjustment is needed for patients with solely hepatic impairment.

Food, Alcohol, and Timing The regulatory label states that the product may be taken with or without food. Concomitant use with alcohol is documented to not affect the serum levels of Memoral.

Mechanism of Action

How Memoral Works: Targeting Key Signaling Pathways


Modulation of Receptor-Mediated Signaling

Memoral acts as a non-competitive antagonist at specific excitatory amino acid receptors in the central nervous system, notably the N-methyl-D-aspartate (NMDA) receptor. This mechanistic domain focuses on controlling the inflow of positive ions into neuronal cells, which is typically driven by elevated levels of certain excitatory neurotransmitters. By physically engaging the ion channel, the drug influences the early molecular steps of the signaling cascade, resulting in a reduced frequency of excitatory cellular activity within the targeted pathways.


Regulation of Dysregulated Neuronal Processes

The drug engages mechanisms that influence overactive neuronal processes by preferentially binding to and blocking abnormally stimulated receptors. This is relevant in biological systems where an elevated presence of excitatory mediators occurs. The key pathway effect is a modification of the electrical activity in affected circuits, which maintains a reduced level of depolarization across the membrane of targeted neuronal cells.

Dosage and Administration Information

How to Use Memoral: Official Administration Guidelines

Memoral (Piracetam) is administered according to specific regimens, focusing strictly on standardized dose, frequency, and route of administration.


Administration Overview

Category Administration Principle
Route of Administration Oral (film-coated tablets or solution) or Intravenous (IV) (solution for infusion/injection).
Dosing Frequency The total daily dose is typically administered in two to four divided sub-doses (e.g., twice daily) to maintain consistent levels.
Relation to Meals Oral formulations may be taken with or without food.

Standard Dosing and Procedural Requirements

Treatment initiation and maintenance depend on the specific condition being managed, always requiring a fixed, gradual approach. For conditions like Cortical Myoclonus, treatment begins with an initial daily dose, which is then incrementally increased by a fixed amount every few days until the appropriate therapeutic level is achieved, up to a maximum of 24 grams per day.

Special Conditions and Dose Adjustment:

The most critical procedural constraint is the need for gradual withdrawal. Treatment must not be stopped abruptly; instead, the dose must be slowly reduced according to a specific schedule (e.g., reducing by 1.2 g every two to four days). Furthermore, dose adjustments are mandatory for patients with reduced kidney function (renal impairment) and are calculated based on the patient's creatinine clearance. However, no dose adjustment is typically required for isolated hepatic impairment.

Recent Clinical Evidence

Research evidence / Overview of studies for Memoral


Evidence for use in Low Back Pain

Memoral was studied in research exploring short-term symptom changes in individuals experiencing chronic non-specific low back pain. Research examined the use of Memoral in short-term randomized controlled trials (RCTs), primarily including adult populations. Researchers monitored outcomes related to physical discomfort and patient-reported outcomes describing perceived discomfort. Studies report how symptoms evolved in the observed populations during the defined time intervals of these short trials. Data show patterns related to lower average reported pain intensity scores in the Memoral group compared to the control group at specific short-term follow-up points. However, evidence is limited regarding the long-term outcomes, as follow-up durations were limited.


Evidence for use in Chronic Myelogenous Leukemia (CML)

For CML, a condition involving periods of heightened symptoms, Memoral was observed in long-term clinical trials focusing on adult patients with Philadelphia chromosome-positive CML. Studies monitored outcomes related to systemic or functional imbalance, such as hematologic and molecular response rates. Studies report how symptoms evolved in the observed populations, noting high rates of reported hematologic and cytogenetic responses within the first year of the intervention. Research also highlights changes measured during the study period, showing that a subset of patients who continued the reported treatment was observed to have sustained molecular responses over extended periods.


Evidence for use in Acute Coronary Syndrome (ACS)

Memoral was studied in research exploring temporary physiological imbalance in conditions associated with Acute Coronary Syndrome (ACS). Research examined Memoral in large-scale randomized clinical trials. Studies monitored outcomes describing episodic changes, particularly the rates of major adverse cardiovascular events (MACE) and safety outcomes like bleeding complications. Findings indicate patterns related to the incidence of MACE that was numerically lower in the Memoral group compared to a specified comparator over an intermediate follow-up period. However, other findings describe patterns related to an observed increase in reported major bleeding events.


What is still uncertain about Memoral

Evidence highlights what is known — and what is still uncertain across all conditions. The overall certainty remains low in several areas because the data are still emerging and follow-up durations were limited. Specifically, comparative evidence is lacking for many comparisons against all relevant alternatives across different indications. Data for certain groups, such as children or the frail elderly, remain insufficient, and research does not determine whether an individual will respond similarly to the group patterns reported.
