Renal Dose
Administration
May be taken with or without food. Keep a consistent diet. A change in diet to foods high in protein may delay levodopa absorption & reduce amount taken up in circulation. Excessive acidity also delays stomach emptying & thus delays levodopa absorption. Fe salts (eg in multivit prep) may also reduce amount of levodopa available to the body. Swallow whole.
Contra Indications
Hypersensitivity. Narrow angle glaucoma. Should not be used in patients with suspicious, undiagnosed skin lesions or a history ot melanoma.
Precautions
Periodic monitoring of hepatic, renal, haematopoietic and CV functions in patients on prolonged therapy. Monitor for changes in IOP in patients with chronic wide-angle glaucoma. Caution when used in patients with biliary obstruction. Caution when interpreting plasma and urine levels of catecholamines and their metabolites. Withdrawal should be gradual.
Lactation: not known if excreted in breast milk; use caution
Pregnancy-Lactation
Pregnancy Category: C
Lactation: not known if excreted in breast milk; use caution
Interactions
Increased risk of postural hypotension when used concurrently with hypotensive drugs. Severe orthostatic hypotension may result from concurrent usage with MAOIs. Dopamine D2 receptor antagonists, phenytoin or papaverine may reduce the efficacy of levodopa. Iron salts may reduce the bioavailability. Concurrent usage with drugs that interfere with biliary excretion may lead to increased plasma levels of entacapone. May depress prolactin secretion and increase growth hormone levels.

Mode of Action
Levodopa is the metabolic precurosor of dopamine, it crosses the blood-brain barrier and is converted to dopamine in the brain. Carbidopa increases the amount of levodopa that is transported into the CNS by inhibiting the decarboxylation of peripheral levodopa. Entacapone is a selective inhibitor of catechol-o-methyltransferase. Given concurrently, entacapone results in greater and more substained plasma levels of levodopa, leading to greater control of parkinsonism symptoms.
