			==Drug Usage==
			Entacapone is indicated for:
			*Treating "wearing-off" symptoms in patients with Parkinson's disease when used in conjunction with levodopa and carbidopa.

			==Mechanism of Action==
			Entacapone works by inhibiting the enzyme COMT, which metabolizes levodopa. This inhibition increases the bioavailability of levodopa, allowing it to remain active longer in the body and enhancing its therapeutic effects.

			==Route of Administration==
			Orally, and can be taken with or without food.

			==Dosages==
			*200 mg with each dose of levodopa/carbidopa, up to 8 times daily.

			==Side Effects==

			==Pharmacokinetics==
			*Onset Time: Peak plasma concentrations occur approximately 1 hour after oral administration.
			*Duration: The half-life of entacapone is about 0.3 to 0.7 hours.

			==Drug Precautions==
			'''Pregnancy
			*Safety during pregnancy is not established; consult a healthcare provider if or plan to become pregnant.

			'''Breastfeeding
			*It is unknown if entacapone passes into breast milkl nursing mothers should consult their doctor before use.

			'''Drug Monitoring Items

			Monitoring should include:
			*Liver function tests (due to potential liver enzyme elevations)
			*Renal function assessments

			'''Drug Interactions

			Entacpone has major interactions with the following medications:
			*MAO inhibitors (e.g. phenelzine, tranylcypromine): Combining these can potentially lead to severe hypertensive reactions. Entacapone should not be used with non-selective MAO inhibitors.
			*Warfarin: Entacapone may increase INR levels in patinets on warfarin therapy. Close monitoring is recommended.

			Some moderately significant interactions include:
			*Anti depressants (e.g. venlafaxine, desipramine)
			*Antidiabetic medications (e.g. hlipizide, rosiglitazone)
			*Certain antihypertensives (e.g. irbesartan, losartan)
			*Metoclopramide
			*Isoproterenol
			*Methyldopa

			==FAQ==
			'''How Should I Take the Tablet?

			Take entacapone with each dose of levodopa/carbidopa as prescribed. It can be taken with or without food.

			'''What Should I Avoid While Taking?

			Avoid alcohol and other sedatives that may increase drowsiness.

			'''What Happens if I Miss a Dose?

			Take the missed dose as soon as you remember unless it is close to your next scheduled dose. Do not double up on doses.
