Drug 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.
Drug 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.
