Drug_category:Dopamine Agents; Antiparkinson Agents; Antidyskinetics; ATC:N04BA01; ATC:N04BA04
Indication:For the treatment of idiopathic Parkinson-s disease (Paralysis Agitans),
postencephalitic parkinsonism, symptomatic parkinsonism which may follow injury to
the nervous system by carbon monoxide intoxication, and manganese intoxication.
Pharmacology:Levodopa (L-dopa) is used to replace dopamine lost in Parkinson-s disease because
dopamine itself cannot cross the blood-brain barrier where its precursor can.
However, L-DOPA is converted to dopamine in the periphery as well as in the CNS, so
it is administered with a peripheral DDC (dopamine decarboxylase) inhibitor such as
carbidopa, without which 90% is metabolised in the gut wall, and with a COMT
inhibitor if possible; this prevents about a 5% loss. The form given therapeutically
is therefore a prodrug which avoids decarboxylation in the stomach and periphery,
can cross the blood-brain barrier, and once in the brain is converted to the
neurotransmitter dopamine by the enzyme aromatic-L-amino-acid decarboxylase.
Mechanism_of_action:Striatal dopamine levels in symptomatic Parkinson-s disease are decreased by 60 to
80%, striatal dopaminergic neurotransmission may be enhanced by exogenous
supplementation of dopamine through administration of dopamine-s precursor,
levodopa. A small percentage of each levodopa dose crosses the blood-brain barrier
and is decarboxylated to dopamine. This newly formed dopamine then is available to
stimulate dopaminergic receptors, thus compensating for the depleted supply of
endogenous dopamine.
