Product Description
Mechanism of Action
Entacapone is a selective, reversible inhibitor of catechol‑O‑methyltransferase (COMT). COMT normally metabolizes levodopa and dopamine via methylation, reducing their bioavailability. By inhibiting peripheral COMT, entacapone prolongs levodopa plasma half‑life, stabilizes dopaminergic stimulation and smooths motor fluctuations in Parkinsonian models. It does not cross the blood–brain barrier significantly.
Benefits and Advantages
Used in dopaminergic‑pathway research, COMT‑inhibition assays, Parkinson’s disease pharmacokinetic modelling, and levodopa‑synergy studies.
Side Effects and Risks
Risks include diarrhea, orange urine discoloration, dyskinesia (via enhanced levodopa effect), hepatotoxicity (rare), and orthostatic hypotension. Handle with COMT‑inhibitor precautions.
