Trivastal LA

Product Overview

Trivastal LA is a prescription medication containing piribedil as its active component. This dopamine receptor agonist is primarily prescribed for managing symptoms of Parkinson’s disease and restless legs syndrome (RLS). The long-acting tablet formulation ensures gradual medication release, providing continuous symptom control with convenient once-daily administration. By stimulating dopamine receptors in the central nervous system, Trivastal LA enhances motor function and alleviates characteristic symptoms of these neurological conditions, thereby improving patients’ daily functioning and quality of life.

Uses

This medication is clinically approved for:
– Symptomatic treatment of Parkinson’s disease (including tremor, rigidity, and bradykinesia)
– Management of moderate-to-severe restless legs syndrome (RLS)
Trivastal LA effectively reduces motor dysfunction in Parkinson’s patients and diminishes the uncomfortable limb sensations and movement urges associated with RLS, particularly during nighttime rest periods.

How to Use

Administration guidelines:
– Take orally with water; do not crush, chew, or split tablets
– Standard dosing is once daily, preferably with morning meals
– Dosage adjustments should only be made under medical supervision
– Maintain consistent timing for optimal therapeutic effects
– If a dose is missed, take when remembered unless close to next scheduled dose

Mechanism of Action

Piribedil functions as:
– A selective dopamine D2/D3 receptor agonist
– An alpha-2 adrenergic receptor antagonist
This dual mechanism enhances dopaminergic neurotransmission in nigrostriatal pathways while improving cerebral blood flow. The sustained-release formulation maintains stable plasma concentrations, ensuring continuous receptor stimulation for prolonged symptom control.

Dosage and Administration

Standard dosing protocol:
– Initial dose: Typically 50mg once daily
– Maintenance range: 50-150mg daily (adjusted gradually)
– Maximum daily dose: 250mg (in divided doses)
Special populations:
– Elderly: Initiate with lower doses
– Hepatic impairment: Requires dose reduction
– Renal impairment: No significant adjustment needed

Therapeutic Benefits

Clinical advantages include:
– Improved motor coordination and mobility
– Reduced Parkinsonian tremor severity
– Decreased RLS symptom frequency/intensity
– Enhanced sleep quality and duration
– Lower incidence of peak-dose dyskinesias
– Convenient dosing schedule improves compliance

Common Adverse Effects

Frequently reported reactions (≥1% incidence):
– Gastrointestinal: Nausea (15%), dyspepsia (8%)
– Neurological: Dizziness (12%), somnolence (9%)
– Cardiovascular: Orthostatic hypotension (5%)
– Psychiatric: Vivid dreams (4%)
Most side effects are dose-dependent and diminish with continued therapy.

Important Precautions

Special warnings:
– Monitor for impulse control disorders
– Caution in patients with cardiovascular risk factors
– Risk of sudden sleep onset during daily activities
– Potential for drug-induced psychosis in elderly
Contraindications:
– Hypersensitivity to piribedil
– Severe hepatic dysfunction
– Concomitant use with antipsychotics

Storage Requirements

Proper storage conditions:
– Temperature: 15-30°C (59-86°F)
– Protection from humidity and light
– Keep in original blister packaging
– Store securely away from children
– Discard expired medication properly
