Understanding Trimetazidine 80mg: Uses, Dosage, and Side Effects

Jul 31, 2024

What Is Trimetazidine 80 mg?

Trimetazidine 80 mg is a prescription formulation of trimetazidine used primarily as an anti-anginal medicine for patients with stable angina who remain symptomatic despite appropriate first-line treatment or who cannot tolerate it.

An 80 mg formulation has been developed as a modified-release formulation that can allow once-daily administration, unlike some older trimetazidine formulations. Clinical research has compared modified-release trimetazidine 80 mg once daily with 35 mg modified-release twice daily and found comparable safety profiles in the studied population.

Importantly, 80 mg does not mean that every trimetazidine product is interchangeable with every other strength or formulation. Current product information in some markets identifies an 80 mg product as an extended-release capsule containing trimetazidine dihydrochloride 80 mg, while other products may have different strengths and release characteristics.

Trimetazidine 80 mg Uses

The principal use of trimetazidine is the symptomatic treatment of stable angina pectoris.

Angina is chest discomfort caused by inadequate blood flow and oxygen delivery to the heart muscle. It may occur during physical activity or other situations that increase the heart's oxygen requirements.

Trimetazidine has a different mechanism from medicines that primarily reduce heart rate or blood pressure. It acts as a metabolic anti-anginal agent, helping myocardial cells use energy more efficiently when oxygen availability is limited.

According to the European Medicines Agency (EMA), trimetazidine's authorised role was restricted to add-on symptomatic treatment of angina in patients who are inadequately controlled by or intolerant to other anti-anginal medicines.

Is trimetazidine 80 mg used for sudden chest pain?

No.

Trimetazidine should not be considered an emergency treatment for an acute angina attack or unexplained chest pain.

If chest pain is sudden, severe, persistent, occurs at rest, or is accompanied by shortness of breath, sweating, fainting, nausea or pain spreading to the arm, back, neck or jaw, seek urgent medical attention.

Do not wait for trimetazidine to relieve potentially serious chest pain.

How Does Trimetazidine 80 mg Work?

Trimetazidine modifies myocardial energy metabolism.

When the heart has insufficient oxygen, maintaining efficient energy production becomes important. Trimetazidine promotes a metabolic shift toward glucose oxidation, which can improve the efficiency of ATP production under conditions of limited oxygen availability.

In simple terms, trimetazidine helps the heart make better use of available energy during oxygen shortage.

However, this does not mean that trimetazidine removes coronary artery blockages or cures coronary artery disease. It should therefore be viewed as part of an appropriate cardiovascular treatment plan rather than as a replacement for other prescribed heart medicines.

Trimetazidine 80 mg Dosage

The appropriate dose depends on the specific formulation, prescription, kidney function, age and overall clinical condition.

Some modified-release 80 mg formulations have been designed for once-daily use. Clinical studies specifically evaluated trimetazidine modified-release 80 mg once daily against modified-release 35 mg twice daily.

However, patients should not use the research dosage as a personal prescription.

Important dosing point

Do not assume that:

35 mg twice daily = any 80 mg product taken in the same way.

Different formulations release the medicine differently. Current registered product information for an 80 mg extended-release capsule identifies it as a prescription-only medicine, demonstrating why the dosage form needs to be checked rather than relying on the number alone.

How should trimetazidine 80 mg be taken?

Take it exactly according to your doctor's instructions and the product's patient information leaflet.

If your prescribed product is modified- or extended-release, do not crush, chew or alter the capsule/tablet unless the specific product information says that doing so is safe.

If you miss a dose, follow the missed-dose instructions supplied with your medicine. Do not take an extra dose simply to compensate unless your healthcare professional specifically tells you to do so.

Trimetazidine 80 mg Benefits

When appropriately prescribed for stable angina, trimetazidine may help reduce angina symptoms and improve functional capacity.

Research involving modified-release trimetazidine 80 mg once daily has reported reductions in angina attacks and short-acting nitrate use in patients with chronic coronary syndrome who remained symptomatic despite background anti-anginal therapy. A large prospective observational V-GOOD study included 1,026 patients across 70 sites and reported improvement in several symptom-related outcomes after treatment was added.

Earlier real-world research involving more than 3,000 patients also reported reductions in weekly angina attacks and short-acting nitrate consumption after trimetazidine 80 mg once daily was introduced.

These findings should be interpreted correctly: observational studies can demonstrate outcomes in routine practice, but they do not mean every patient will experience the same response.

Potential practical advantage of the 80 mg modified-release formulation

One potential advantage is simplified dosing.

A once-daily modified-release regimen may be easier for some patients to follow than a regimen requiring multiple daily doses. A clinical acceptability study specifically investigated this simplified 80 mg once-daily approach.

Nevertheless, convenience should never be a reason to switch formulations without medical advice.

Trimetazidine 80 mg Side Effects

Like other medicines, trimetazidine can cause adverse effects.

Potential side effects can include:

  • Dizziness
  • Headache
  • Nausea
  • Vomiting
  • Indigestion
  • Abdominal discomfort
  • Diarrhoea
  • Weakness or fatigue
  • Movement-related symptoms in susceptible patients

The most important safety issue to understand is the possibility of movement disorders, including Parkinsonian symptoms.

The EMA has specifically warned about Parkinsonism and related movement disorders associated with trimetazidine. It recommends that patients with Parkinson disease or Parkinsonian symptoms should not receive the medicine.

Symptoms that require medical attention

Contact your doctor promptly if you develop new:

  • Tremors
  • Muscle stiffness
  • Slowness of movement
  • Difficulty walking
  • Balance problems
  • Shuffling gait
  • Restless-leg symptoms
  • Other unusual involuntary movements

The EMA recommends definitive withdrawal of trimetazidine if movement disorders such as Parkinsonian symptoms develop.

Trimetazidine 80 mg Precautions

Before taking trimetazidine, tell your doctor if you have kidney disease, Parkinson disease, tremors, balance problems or other neurological symptoms.

Kidney function

Kidney function is particularly important because reduced renal clearance can increase exposure to trimetazidine.

EMA safety recommendations contraindicate trimetazidine in patients with severe renal impairment, while dose reduction and additional caution may be necessary in certain patients with moderate renal impairment. Older patients may also require particular attention because kidney function can decline with age.

Do not calculate your own dose based on a creatinine value found on a laboratory report. Your doctor needs to interpret kidney function in the context of your age, clinical history and other medicines.

Who Should Not Take Trimetazidine 80 mg?

According to EMA safety recommendations, trimetazidine should not be used in patients with:

  • Parkinson disease
  • Parkinsonian symptoms
  • Tremors or certain related movement disorders
  • Severe renal impairment
  • Known hypersensitivity to the active substance or relevant excipients

The EMA also recommends caution in patients with moderate renal impairment and older adults.

The exact contraindications and prescribing information applicable to a product can depend on its approved product information and jurisdiction, so Indian patients should check the medicine leaflet and follow their prescribing doctor's instructions.

Can Trimetazidine 80 mg Be Used for Tinnitus or Vertigo?

Patients should not self-medicate with trimetazidine for tinnitus or vertigo.

The EMA concluded that the benefits of trimetazidine did not outweigh the risks for tinnitus, vertigo and certain visual-field disturbances and recommended that these uses no longer be authorised in the European Union.

If you experience dizziness or vertigo, the cause should be evaluated rather than automatically treating it with trimetazidine.

Trimetazidine 80 mg Price in India

The price of trimetazidine 80 mg in India varies by brand, formulation, pack size, seller, location and current discounts.

Current Indian online pharmacy listings show several 80 mg trimetazidine products. For example, recent listings include 80 mg extended-release products such as Timzid OD 80, Trineed-MR 80 mg, Cytogard OD 80 and other products. These listings also identify the products as prescription medicines.

Because medicine prices and stock can change, a website price should not be treated as a permanent MRP or universal India-wide price.

Where can I buy trimetazidine 80 mg?

Use a licensed pharmacy and follow applicable prescription requirements.

Current Indian listings demonstrate that 80 mg products are available through online pharmacy channels, but availability, pricing and delivery depend on location and stock.

Do not purchase an unfamiliar product solely because it is cheaper.

Trimetazidine 80 mg: Brand vs Generic

Trimetazidine is the active ingredient; individual pharmaceutical companies may market different products containing the same medicine.

When considering a replacement product, do not compare only the 80 mg number.

A pharmacist or doctor should confirm that the proposed alternative has:

  • The same active ingredient
  • The same strength
  • The appropriate modified/extended-release characteristics
  • The correct dosage form
  • Appropriate regulatory status

An 80 mg extended-release product should not automatically be treated as interchangeable with a different trimetazidine formulation.

Trimetazidine 80 mg vs 35 mg

Both strengths can be used in modified-release treatment strategies, but they are not simply interchangeable tablet-for-tablet.

Clinical research evaluated modified-release 80 mg once daily against modified-release 35 mg twice daily and found similar safety profiles in the studied stable-angina population.

The choice depends on the formulation and prescription.

Never change from 35 mg to 80 mg—or from 80 mg to 35 mg—without medical advice.
