What Type of Medicine is Lompasar?

Lompasar is a trade name for the pharmaceutical product containing the active ingredient Folic Acid, which is officially classified as a water-soluble B-complex vitamin and nutritional supplement. Its general purpose is to ensure the body has the critical components required for the healthy development and maintenance of cells.

The ingredient is considered an essential cofactor because the human body cannot produce it internally and must obtain it through diet or supplementation. The central role of Folic Acid in synthesizing DNA and RNA is fundamental for all cell division and growth processes, particularly those supporting red blood cell production.

Differentiating Lompasar's Composition and Form

Lompasar is manufactured by Aversi Pharma and is generally provided as a 5 mg oral tablet, distinguishing it from many low-dose over-the-counter supplements. The core component is synthetic Folic Acid, which achieves higher bioavailability (better absorption) than the naturally occurring folate found in many food sources.

This formulation is typically used to provide therapeutic supplementation, ensuring easy administration for patients who require a consistent supply of this vital nutrient.

What side effects are possible with Lompasar?

Possible Side Effects and Safety Information for Lompasar

Regulatory authorities compile and monitor the safety profile of Lompasar based on clinical trial data and post-marketing surveillance systems (e.g., FDA Adverse Event Reporting System (FAERS), EudraVigilance). Safety data is structured using the Medical Dictionary for Regulatory Activities (MedDRA) terminology, which classifies adverse reactions by System Organ Class (SOC) and Preferred Term.

Categories of Adverse Reactions

The most frequently referenced System Organ Classes for Lompasar and related pharmacological agents include Gastrointestinal disorders (e.g., constipation, abdominal distension), Nervous system disorders, and Metabolism and nutrition disorders (e.g., electrolyte imbalances). Infections and infestations, Hepatobiliary disorders, and Respiratory, thoracic and mediastinal disorders are also documented as relevant safety areas.

Serious Adverse Reactions and Safety Concerns

Specific serious adverse events (SAEs) that require mandatory reporting and regulatory scrutiny include severe conditions such as Renal failure, Sepsis, and specific issues related to Blood and lymphatic system disorders (e.g., haemolytic anaemia). Regulatory documents may use terms like "Rare" or "Very Rare" to categorize the frequency of certain serious adverse events, although precise frequency percentages for all reactions are often determined over time through ongoing surveillance.

Population-Specific Safety Considerations

Safety data has highlighted particular considerations for specific patient populations. Notably, in perinatal safety data associated with similar drug exposure, congenital abnormality or disability has been observed. Exposure-related risk patterns, such as the timing of serious cutaneous adverse reactions (SCARs) being most frequent early in the treatment course, are monitored and inform official labeling.

Regulatory documentation emphasizes the need for continuous analysis and notification of all Serious Adverse Events to ensure the official safety information remains current.

Overdose and Emergency Response

Overdose and When to Seek Help

Official regulatory information states that Folic Acid has a generally low acute toxicity profile. Even extremely high doses are deemed unlikely to cause harm [Source 1.4]. Consequently, regulatory labels frequently state that no specific emergency treatment or antidote is necessary in the event of an overdose [Source 2.4].

Documented Overdose Presentations

While specific symptoms of acute overdose are not generally reported, high doses have been rarely associated with effects on two main systems:

  • Gastrointestinal Effects: These may include anorexia, nausea, and flatulence [Source 1.4].
  • Central Nervous System (CNS) Effects: These effects may manifest as sleep disturbances, agitation, confusion, or depression [Source 1.2].

Critical Regulatory Warnings and Required Action

Regulators emphasize the primary long-term risk: high doses, such as 5 mg or more, may mask the hematological symptoms of an underlying Vitamin B12 deficiency [Source 2.6]. This masking allows irreversible neurological damage (cobalamin neuropathy) to progress [Source 2.4]. This risk is a specific concern for elderly people [Source 2.4].

Immediate medical help is required for the first sign of a severe allergic reaction, such as anaphylactic shock or dyspnoea [Source 1.4]. For general suspected overdose, official guidance mandates seeking medical attention immediately [Source 1.2]. Management is defined as symptomatic and supportive treatment [Source 1.4].

Therapeutic Uses of Lompasar

What Lompasar Treats: Main Uses and Benefits

Lompasar (Folic Acid 5 mg) generally provides supportive therapeutic benefit by addressing vital nutritional deficits and offering assistance during phases of high biological demand. The medication is applied across three primary clinical domains that may ease patient burden and support risk management.


The medication is commonly used to manage megaloblastic anemia related to systemic imbalance, to manage the risk of serious Neural Tube Defects (NTDs) in the periconceptional period, and is applied in clinical settings involving specific drug treatments, such as methotrexate. This application contributes to easing the symptom burden on the patient, helping address distressing and disruptive symptoms like chronic fatigue, weakness, painful mouth ulcers, and associated gastrointestinal issues.

“The use of the medication is focused on providing supportive relief during symptomatic periods and assists with maintaining functional stability.”


Quick Fact: Relief for Systemic Imbalance

Lompasar supports the maintenance of energy and physical comfort by managing symptoms related to systemic imbalance caused by the deficiency, helping patients cope more steadily with fatigue and weakness that create noticeable interference with daily functioning.

Eligibility and Restrictions for Use

Eligibility Map: Who can and cannot use Lompasar — Official Regulatory Information

Eligibility Scope

Category Official Regulatory Statement
Populations for whom use is allowed (as stated in label) Adults and children over 1 year; women at high risk for neural tube defects; prophylaxis in chronic hemolytic states and renal dialysis patients.
Populations for whom use is not recommended (if applicable) The 5 mg tablet is not recommended for infants or very young children; long-term use is not recommended for the elderly unless B12 deficiency is ruled out.
Populations for whom use is contraindicated Patients with hypersensitivity to Folic Acid or excipients; untreated cobalamin (Vitamin B12) deficiency or undiagnosed megaloblastic anemia; malignant disease (unless for confirmed folate deficiency); and those with rare hereditary sugar intolerances.

Key Eligibility Classifications

Category Official Regulatory Statement
Age-related eligibility rules Adults are eligible. Children over 1 year are eligible, but infants are eligible by weight and require an alternative formulation.
Pregnancy and lactation eligibility status (if explicitly documented) Permitted (Category A) for use during both pregnancy and lactation, especially for high-risk indications.
Eligibility-related restrictions Use requires caution in patients who may have folate-dependent tumors.

Connection to the overall eligibility profile: Regulatory documents strictly define eligibility based on the critical exclusionary principle: Folic Acid must not be used alone to treat undiagnosed megaloblastic anemia, due to the severe neurological risks associated with masked Vitamin B12 deficiency. Eligibility is otherwise governed by allergy status, the presence of specific comorbidities, and the suitability of the 5 mg tablet formulation for different age groups.

What should I know about interactions with other medicines?

Interactions with other medicines and products

Lompasar (Folic Acid 5 mg) has formally documented interaction patterns that are specified in regulatory labeling, primarily involving medications used for epilepsy and certain antifolate agents.

Documented Drug-Drug Interactions

Interacting Substance Category Official Interaction Outcome
Anticonvulsants (e.g., Phenytoin, Primidone, Phenobarbital) Folic Acid is documented to antagonize the anticonvulsant action; co-administration may result in decreased anticonvulsant plasma levels and potential loss of seizure control.
Antifolate Agents (e.g., Methotrexate, Pyrimethamine) Folic Acid may reduce the effects of antifolate medicines. However, Folic Acid is also intentionally co-administered with Methotrexate in certain contexts to reduce the risk of toxic adverse reactions.
Absorption-Reducing Agents (e.g., Sulfasalazine, Cholestyramine, Antacids) Co-administration may reduce the absorption of Folic Acid, which may necessitate a specific separation of administration timing.

Other Official Interaction Constraints

Official labeling mandates specific conditions for co-administration:

  • Timing Separation Rules: Folic Acid must be taken at least two hours after aluminum or magnesium-containing antacids, and must be separated by four to six hours from cholestyramine to maintain expected absorption.
  • Procedural Interference: Certain antibiotics, such as chloramphenicol, are documented to interfere with the laboratory assay used to measure folate levels, which may result in falsely low diagnostic results.
  • Population Restriction: Long-term therapy with Folic Acid at doses exceeding 0.1 mg daily is officially contraindicated in patients with untreated Vitamin B12 deficiency (pernicious anemia), as it may mask the blood disorder while allowing severe neurological damage to progress.

Mechanism of Action

The mechanism of Folic Acid (Lompasar) is centered on its critical role as a metabolic precursor, which, once activated, functions as an essential co-enzyme in fundamental biosynthetic pathways.

Folic Acid requires activation by the enzyme Dihydrofolate Reductase ( DHFR) to form tetrahydrofolate ( THF) cofactors. These cofactors do not modulate receptors but act as essential carriers of one-carbon units within the cell. This initial enzymatic process provides the necessary co-enzymes for metabolic reactions requiring one-carbon transfer.

The active THF derivatives directly support nucleotide synthesis by engaging enzymes like Thymidylate Synthase. By facilitating the creation of the DNA and RNA building blocks (Purines and Thymine), the mechanism is fundamental to genetic material synthesis and is required for mitosis (cell division). This action influences the maturation of cells, particularly those in rapidly reproducing tissues.

This mechanism is crucial for the Hematopoietic System and is required for the proliferation of precursor cells in the bone marrow, thus influencing the morphology of red blood cells. However, the pathway is interdependent; the function of the folate co-enzyme is absolutely dependent on Vitamin B12 (Cobalamin) for the essential homocysteine recycling step, a dependency that presents a key limitation to the mechanism.

Dosage and Administration Information

Official Administration Guidelines for Lompasar

Lompasar (Folic Acid 5 mg) is administered orally and must be swallowed whole with a drink of water. The tablet can be taken with or without food, establishing a flexible time-relationship with meals.

Dosage Regimens and Frequency

The standard regimen for adults and children over one year is typically 5 mg once daily for high-strength supplementation. For cases involving severe malabsorption, the dose may be increased, potentially up to 15 mg daily. While a daily schedule is most common for therapeutic use, certain prophylactic and maintenance regimens may follow a once weekly pattern.

Administration Scope Official Guidelines
Route of Administration Oral (Tablet).
Standard Dosing 5 mg once daily (Adults/Children >1 Year).
Frequency Pattern Daily or Weekly (maintenance/prophylaxis).

Use Patterns and Procedural Rules

Treatment duration is defined by the underlying condition. For instance, the initial course for anaemia is typically four months, whereas use for chronic conditions (e.g., ongoing renal dialysis) may extend to long-term maintenance. When used for the prevention of Neural Tube Defect recurrence in high-risk patients, the regimen begins before conception and continues throughout the first trimester.

Antacids containing aluminium or magnesium must be taken at least two hours after Lompasar to mitigate reduced absorption. If a daily dose is missed, a double dose should not be taken; the patient should continue with the next scheduled dose. For infants (up to one year), a liquid formulation is usually prescribed, with dosing calculated based on body weight.

Recent Clinical Evidence

Lompasar: Recent Clinical Evidence


Evidence for Managing Folate-Related Anemia and Deficiency

Research exploring the use of high-dose Folic Acid for systemic folate deficiency includes Randomized Controlled Trials (RCTs) and observational studies. These studies primarily monitored hematological endpoints, such as red blood cell folate concentration, and also tracked patient-reported outcomes describing discomfort like chronic fatigue and weakness. Studies reported shifts in these markers and associated symptom patterns following supplementation. However, the evidence primarily focuses on short-term physiological correction of the deficit, and long-term effects regarding maintenance requirements are not fully established. Research notes the critical need to differentiate this context from co-existing Vitamin B12 deficiency in trials.

Evidence for Reducing Risk of Neural Tube Defects (NTDs)

The evidence base for this application relies on large-scale RCTs that largely focused on a similar high-dose (4 mg) in high-risk women during the periconceptional period. Research examined the incidence of Neural Tube Defects (NTDs) in offspring. Studies reported that the rate of NTD occurrence in supplemented groups was lower compared to controls. The 5 mg dose is extrapolated from this robust evidence base, although limited direct RCT evidence exists specifically comparing the 5 mg dose to lower doses in the high-risk setting.

Evidence for Supportive Use with Methotrexate Therapy

The research examining the use of Lompasar alongside methotrexate (MTX) primarily consists of Double-blind RCTs. Research was conducted to explore the association between the supplement and specific side effects observed during MTX therapy for chronic inflammatory conditions. Studies reported that groups receiving supplementation had a pattern of lower rates of elevated liver enzymes compared to those receiving placebo, and the use was associated with higher rates of patient treatment continuation.

Research Gaps and Study Limitations

The evidence landscape highlights areas of ongoing research. Comparative evidence is lacking for the 5 mg dose versus lower doses for NTD risk reduction. Furthermore, data for certain groups remain insufficient, as the evidence surrounding MTX therapy primarily focused on adults with rheumatoid arthritis and psoriasis, leaving subgroup findings uncertain for other patient groups or specific comorbidities.
