What is Entacapone?
Entacapone, the active ingredient in Medapia, is a catechol-O-methyltransferase (COMT) inhibitor presented as an oral tablet for oral use. It is used as adjunct therapy with levodopa/carbidopa in Parkinson's disease to improve motor control and reduce off‑periods.
GNH USA supplies Medapia as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.
What is Entacapone used for?
Entacapone is a COMT inhibitor used in the management of Parkinson's disease.
- Parkinson's disease (early stage): added to levodopa/carbidopa to delay dose escalation. - Parkinson's disease (advanced stage): helps reduce motor fluctuations and off periods. - Parkinson's disease with wearing‑off phenomenon: prolongs levodopa half‑life to improve symptom control.
What are the side effects of Entacapone?
Entacapone may cause a range of adverse reactions, from mild to serious.
Common Side Effects: - Nausea: mild to moderate gastrointestinal upset. - Diarrhea: loose stools that may be transient. - Abdominal pain: discomfort in the stomach area. - Dyspepsia: indigestion or heartburn. - Urine discoloration: darkening of urine without health risk. - Headache: mild to moderate tension-type pain.
Serious or Rare Side Effects: - Hepatotoxicity: elevated liver enzymes or liver injury. - Severe allergic reactions: rash, angioedema, or anaphylaxis. - Neutropenia: reduced white blood cell count increasing infection risk. - Severe liver injury: jaundice, hepatic failure. - Hypotension: marked drop in blood pressure. - Mood changes: depression or suicidal thoughts.
What precautions apply to Entacapone?
Before prescribing Entacapone, clinicians should consider several safety measures.
- Monitor liver function: obtain baseline tests and repeat periodically. - Assess for hypersensitivity: discontinue if rash, angioedema, or anaphylaxis occurs. - Evaluate renal function: adjust use in severe renal impairment. - Avoid in known COMT inhibitor hypersensitivity: contraindicated in patients with prior reactions. - Store at room temperature: keep in the original container, protect from moisture and light.
What does Entacapone interact with?
Entacapone can interact with several medicines, requiring careful management.
Major Interactions (Avoid): - Levodopa/carbidopa: may increase levodopa levels, raising risk of dyskinesia. - Non‑selective MAO inhibitors: risk of hypertensive crisis; avoid concurrent use. - Warfarin: may potentiate anticoagulant effect; monitor INR closely. - Antidiabetic agents: can enhance hypoglycemia; monitor blood glucose.
Moderate Interactions (Monitor Closely): - Antihypertensives: may augment blood‑pressure lowering effects. - CYP2C9 substrates (e.g., phenytoin): possible altered plasma concentrations. - NSAIDs: may increase risk of gastrointestinal irritation.
