Origin Synthetic compound

What is Angintriz and What Pharmacological Class Does it Belong To?

Angintriz is a prescription-only foundational medication containing the active ingredient Trimetazidine Dihydrochloride. This synthetic compound is officially classified as a metabolic agent, often grouped under anti-ischemic agents. Trimetazidine is characterized by its distinct metabolic action, providing a clinical effect without altering heart rate or blood pressure.

Composition and Physical Form of Angintriz

The medication is a single-ingredient product delivered as an oral, modified-release tablet (MR), which is the necessary pharmaceutical form for its consistent therapeutic delivery. The modified-release design, a distinctive feature of this formulation, is crucial for ensuring that the Trimetazidine Dihydrochloride is slowly and evenly released, allowing for sustained action and maintaining a stable concentration of the metabolic agent in the system throughout the day. This stable delivery supports its role as a key component in long-term maintenance therapy.

What is the General Purpose of This Cytoprotective Agent?

The general purpose of Angintriz is to optimize how myocardial (heart muscle) cells generate energy, which helps them sustain function when blood flow is temporarily reduced, such as in ischemic conditions. It achieves this by acting as a partial fatty acid oxidation (pFOX) inhibitor, which prompts the cell to favor the more oxygen-efficient process of glucose oxidation. This metabolic adjustment is beneficial for preserving cellular integrity when oxygen supply is restricted, a mechanism that is clinically recognized for supporting cardiac resilience.

What side effects are possible with Angintriz?

Possible Side Effects and Safety Information

The safety profile of Angintriz (Trimetazidine Dihydrochloride) is established by government regulatory documents, which categorize all known potential risks and limitations based on clinical data and post-marketing surveillance.


Officially Documented Adverse Reactions

Adverse reactions are classified by their frequency of occurrence as documented in regulatory labeling:

  • Common Reactions (occurring in 1/100 to < 1/10 patients) primarily affect the Nervous System (dizziness, headache) and Gastrointestinal System (nausea, vomiting, abdominal pain, diarrhea). Other common effects include skin reactions (rash, pruritus, urticaria) and general weakness (asthenia).

  • Rare Reactions (occurring in 1/10,000 to < 1/1,000 patients) are noted in the Vascular System, including arterial hypotension and orthostatic hypotension (fall in blood pressure upon standing), which may lead to falls, particularly in patients taking antihypertensive treatment.

  • Frequency Not Known reactions are observed primarily through post-marketing experience. These include the occurrence or worsening of Parkinsonian symptoms (tremor, hypertonia, gait instability), hepatitis (liver disease), and severe cutaneous reactions like angioedema.


Key Safety Constraints and Special Populations

Regulatory documents specify key constraints for the use of Trimetazidine Dihydrochloride:

  • Movement Disorders: The medicine is contraindicated in patients with pre-existing Parkinson's disease, parkinsonian symptoms, tremors, or related movement disorders. Parkinsonian symptoms that develop during treatment are usually reversible upon discontinuation.

  • Renal Impairment: Angintriz is contraindicated in individuals with severe renal impairment. Caution is advised for elderly patients (over 75 years) and those with moderate renal impairment due to the potential for increased systemic exposure.

  • Driving and Machinery: The possibility of dizziness and drowsiness may affect the ability to drive and use machines.

Overdose and Emergency Response

Overdose and When to Seek Help

Official regulatory documentation states that very limited information is available on Trimetazidine Dihydrochloride overdose. Because of this, the management of overdose is officially directed as symptomatic and supportive treatment, as no specific antidote is described in the regulatory texts.

When an overdose of Angintriz occurs, the explicit instruction from the prescribing information is to Inform your doctor or pharmacist immediately. This action is mandated because high systemic exposure to the medication may lead to significant physiological effects.

Manifestations anticipated from high exposure are generally related to the cardiovascular and neurological systems. These include the risk of Arterial Hypotension and Orthostatic Hypotension (a drop in blood pressure upon standing) which can lead to Dizziness and Fall. High exposure may also result in the worsening of extrapyramidal symptoms, such as tremor or gait instability.

Specific populations are noted to have an increased risk of systemic exposure that could amplify overdose effects. These include elderly patients (75 years and older) and patients with moderate renal impairment (creatinine clearance 30-60 mL/min). The overall regulatory guidance is framed by the constraint of limited data, placing emphasis on immediate professional contact and supportive care.

Therapeutic Uses of Angintriz

Angintriz is relevant within therapeutic domains marked by symptoms linked to organ-specific functional stress. The use of this medication is commonly applied as add-on therapy for the symptomatic management of stable angina pectoris in adults when first-line antianginal treatments are insufficient or not tolerated. Its use is applicable within clinical settings that involve acute or disruptive symptom patterns, often used during phases when symptoms become more noticeable.

The medication is relevant for conditions involving episodic or fluctuating manifestations, including stable angina pectoris. It helps address symptom clusters that may become intense or disruptive.

Quick Fact: Support for Symptomatic Periods

Angintriz supports patients by easing symptoms related to physical discomfort, providing support that contributes to easing the overall symptom burden and offers symptomatic relief that helps patients cope more steadily. This support for functional stability may assist with managing symptoms that interfere with daily functioning and contributes to the appropriate management of other supportive treatments.

Eligibility and Restrictions for Use

Official Eligibility Rules for Angintriz

Angintriz (Trimetazidine Dihydrochloride) is officially indicated for use only in adults with stable angina pectoris, provided they are not adequately controlled by or are intolerant to other standard therapies. Regulatory documentation strictly defines several groups who must not use this medicine (contraindications) and other populations for whom use is limited or not recommended.


Absolute Contraindications

Population Group
Patients with a known hypersensitivity to Trimetazidine Dihydrochloride or any excipients.
Individuals with Parkinson disease, Parkinsonian symptoms, tremors, restless legs syndrome, or other related movement disorders.
Patients with severe renal impairment (creatinine clearance < 30 ml/min).

Restricted and Non-Recommended Groups

Population Group Regulatory Status
Children and Adolescents (under 18 years) Not Recommended (Safety and efficacy not established).
Pregnancy Avoidance Preferred (Precautionary due to lack of human data).
Lactation/Breastfeeding Not Recommended (Risk to infant cannot be excluded).
Moderate Renal Impairment (CrCl 30-60 ml/min) Conditional Use (Requires caution and a documented dose reduction).

Eligibility is defined by these regulatory constraints, meaning use is limited to the approved adult population only when these specific contraindications and restrictions are avoided.

What should I know about interactions with other medicines?

Angintriz (Trimetazidine Dihydrochloride) is officially documented by major health authorities, including the European Medicines Agency, as possessing a minimal potential for drug interactions. This regulatory profile is established by the medicine's lack of involvement in key pharmacokinetic pathways.

Interaction Category Official Regulatory Finding
Metabolic Interactions None documented. Trimetazidine is not a known substrate, inhibitor, or inducer of the Cytochrome P450 enzyme system, which indicates a negligible potential for affecting the clearance of co-administered medicines.
Contraindicated Combinations No medicinal product combinations are formally listed as prohibited for co-administration based solely on drug-drug interaction risk.
Timing Separation Rules None documented. Official labels specify no mandatory requirements for spacing the administration of Angintriz from other medicines, supplements, or food.

Due to the lack of documented involvement with common metabolic or transporter systems, Angintriz's clearance is not expected to be significantly affected by co-administered medicines. Similarly, official prescribing information confirms that its systemic exposure is not altered by food consumption. The overall interaction structure is defined by this absence of conventional interaction mechanisms.

The only mandatory, interaction-related constraint documented by regulatory authorities concerns specific patient populations. Caution is required in patients with moderate renal impairment (creatinine clearance 30 to 60 mL/min) and the elderly (over 75 years old). This is due to the drug's predominant renal elimination pathway, where reduced clearance in these populations results in an expected increase in systemic exposure.

Mechanism of Action

The mechanism of Angintriz is defined by its targeted intervention in the energy substrate use within the heart muscle cell, producing a specific metabolic sequence.

Molecular Targeting of Fatty Acid Metabolism

The molecule acts as a selective, partial inhibitor of the mitochondrial enzyme Long-chain 3-ketoacyl-CoA thiolase ( LC 3-KAT). This LC 3-KAT is a component of the beta-oxidation pathway. This inhibition reduces the rate of fatty acid oxidation (FAO), which is a primary pathway for energy substrate generation in the cardiomyocyte.

Metabolic Shift and Oxygen Utilization

The suppression of FAO acts to relieve the corresponding inhibitory control exerted on the Pyruvate Dehydrogenase (PDH) enzyme. This metabolic shift promotes the preferential utilization of glucose oxidation for ATP synthesis. The mechanistic outcome is an alteration in the ratio of ATP produced relative to O2 consumed, which is characteristic of enhanced oxygen utilization.

Homeostatic Support During O2 Restriction

The efficiency change stabilizes the cell's energy levels, which preserves the activity of essential membrane-bound ion pumps. This sequence maintains the stability of ion pump function, mitigating intracellular ionic imbalance ( calcium overload) and the accumulation of acidic metabolic byproducts, thereby supporting cell function under conditions of reduced O2 supply.

Dosage and Administration Information

How Angintriz is Used

Angintriz (Trimetazidine Dihydrochloride Modified-Release 35 mg tablets) is administered via the oral route as part of a long-term maintenance treatment plan. The administration of this medicine is guided by specific instructions defined within official documents to ensure proper use and drug delivery.


Standard Labeled Regimen

Administration Component Official Instruction
Dose and Frequency One 35 mg tablet is taken twice daily (morning and evening).
Timing in Relation to Meals Doses must be taken specifically during meals.
Tablet Handling The tablet must be swallowed whole; it must not be chewed, broken, or crushed.

Population-Specific Adjustments

The standard regimen requires modification for certain patient groups, a key principle of its usage protocol:

  • Moderate Renal Impairment (Creatinine Clearance 30-60 mL/min): The dose must be reduced to one 35 mg tablet once daily (in the morning).
  • Elderly Patients: Dose management should proceed with caution, particularly if moderate renal impairment is present; the daily dosage should follow the rules for renal adjustment.
  • Paediatric Population (below 18 years): An official usage pattern is not established, as the safety and efficacy in this age group have not been determined.

Procedural and Duration Principles

The official usage protocol includes instructions for managing administration over time. If a dose is missed, patients are instructed to resume treatment normally with the next scheduled dose and must not take a double dose to compensate. Furthermore, the continuation of the treatment must be assessed after three months of use, and the regimen should be discontinued if no satisfactory use pattern or benefit is observed after this initial assessment period.

Recent Clinical Evidence

Angintriz: Recent Clinical Evidence

Phase III Clinical Trials

One study evaluated the effects of the drug on symptoms. The research examined a diverse cohort over a six-month period. Data collected included patient-reported symptom frequency and severity.

Research evaluated whether combination therapy might lead to different outcomes than monotherapy for chronic inflammation. This study included a control group receiving placebo or monotherapy. The findings were mixed regarding differences in outcomes between the combination group and the monotherapy group.

Additionally, a separate clinical trial examined the drug's effect on pain levels. This open-label study focused on a short-term intervention over 72 hours. It is not yet clear whether this drug administration regimen led to different outcomes in pain severity across the studied population. The study explored whether administering the drug at the start of a flare-up was associated with different outcomes.


Long-term Safety and Tolerability

Research explored whether the drug was associated with long-term side effects over a period of two years. The observed safety events were monitored.

One study evaluated whether the drug might lead to different outcomes compared to existing therapies. Findings from this research require further investigation to establish a clear conclusion about comparative outcomes. Long-term safety research is continuing.


Pediatric Use Studies

A single Phase II study evaluated the drug's effect in patients aged 12 to 17. The study was limited in size, and evidence remains limited regarding the drug's use in this population. The study's design did not allow for a definitive finding on different outcomes in pediatric subjects compared to adults.
