Common Use
Vastarel (trimetazidine) is an anti-ischemic metabolic agent indicated for the long-term symptomatic treatment of stable angina pectoris in adult patients. Unlike conventional antianginal drugs that work by reducing heart rate or dilating blood vessels, trimetazidine operates through a unique cytoprotective mechanism: it inhibits long-chain 3-ketoacyl CoA thiolase (3-KAT), an enzyme involved in fatty acid oxidation in the heart muscle. By partially shifting the heart's energy metabolism from fatty acid oxidation to the more oxygen-efficient glucose oxidation pathway, Vastarel enables cardiac cells to produce more ATP per molecule of oxygen consumed. This metabolic optimization helps the heart muscle function more efficiently under ischemic conditions — when oxygen supply is limited — thereby reducing the frequency and severity of angina attacks, improving exercise tolerance, and decreasing the need for short-acting nitrate rescue medication. Vastarel is prescribed as adjunctive (add-on) therapy when first-line antianginal treatments (beta-blockers, calcium channel blockers, nitrates) are insufficient or not tolerated.

Dosage and Direction
The standard recommended dose of Vastarel is 35 mg twice daily (modified-release/MR tablets), taken during meals — typically one tablet in the morning and one in the evening with food. Swallow the tablet whole with a full glass of water; do not crush, chew, or split modified-release tablets, as this destroys the controlled-release mechanism and may lead to dose dumping. Maintain a consistent dosing schedule for optimal therapeutic effect. Your doctor will determine the appropriate treatment duration based on your clinical response and overall cardiovascular management plan. Do not exceed the prescribed dose or discontinue treatment without consulting your cardiologist.

Precautions
Before starting Vastarel, inform your doctor about all existing medical conditions, particularly kidney impairment (renal insufficiency), movement disorders such as Parkinson's disease, restless legs syndrome, tremors, or any other extrapyramidal symptoms. Trimetazidine has been associated with rare cases of parkinsonian symptoms (tremor, rigidity, bradykinesia, gait instability) — these are usually reversible upon drug discontinuation but require prompt recognition. Patients over 75 years of age are at higher risk for these neurological effects. Vastarel is not intended for the acute treatment of angina attacks — it does not provide immediate relief during chest pain episodes and should not replace sublingual nitroglycerin or other rescue medications. Regular cardiology follow-up with assessment of symptom control and exercise capacity is recommended during long-term therapy. Dose adjustment is necessary in patients with moderate renal impairment.

Contraindications
Vastarel is contraindicated in patients with known hypersensitivity or allergy to trimetazidine dihydrochloride or any excipient in the formulation. It is strictly contraindicated in patients with Parkinson's disease, parkinsonian symptoms, tremors, restless legs syndrome, or any other movement disorders, as trimetazidine may worsen or trigger these conditions. The medication is also contraindicated in patients with severe renal impairment (creatinine clearance below 30 mL/min). Vastarel should not be used during pregnancy or breastfeeding due to insufficient safety data.

Possible Side Effects
Common side effects of Vastarel include dizziness, headache, abdominal pain, nausea, vomiting, diarrhea, indigestion, skin rash, itching, and general weakness or fatigue. These effects are generally mild and transient. The most clinically significant rare adverse effect is the development of parkinsonian or extrapyramidal symptoms — including resting tremor, muscle rigidity, shuffling gait, bradykinesia (slowness of movement), and balance instability. These neurological symptoms typically resolve after drug discontinuation but may take several months to fully clear. Other rare side effects include orthostatic hypotension, palpitations, flushing, and blood count changes (agranulocytosis, thrombocytopenia). Seek immediate medical evaluation if you develop any unexplained tremor, movement difficulties, or persistent neurological symptoms.

Drug Interaction
Vastarel has relatively limited known drug interactions compared to many cardiovascular medications, which is one of its therapeutic advantages. However, it should be used cautiously with other medications that affect the central nervous system, particularly dopamine antagonists (antipsychotics, metoclopramide) which could theoretically potentiate parkinsonian side effects. While no clinically significant interactions with standard cardiovascular drugs (beta-blockers, calcium channel blockers, nitrates, aspirin, statins) have been established, always inform your healthcare provider about all prescription medications, over-the-counter drugs, vitamins, and herbal supplements you are taking.

Missed Dose
If you miss a dose of Vastarel, take it as soon as you remember with food. If it is close to the next scheduled dose, skip the missed dose and continue your regular twice-daily schedule. Do not take a double dose to compensate for a missed one.

Overdose
Limited data is available on Vastarel overdose. An overdose may potentially increase the frequency and severity of known side effects, particularly dizziness, nausea, and neurological symptoms. Seek immediate emergency medical attention if an overdose is suspected. Treatment is supportive and symptom-based, with monitoring of cardiovascular and neurological function.

Storage
Store Vastarel modified-release tablets at controlled room temperature between 15°C and 25°C (59°F to 77°F), protected from moisture and direct sunlight. Keep in original packaging and out of reach of children. Do not use after the expiration date printed on the blister or box.
