Levodopa+carbidopa
About Levodopa+carbidopa
Carbidopa+levodopa is a precursor of dopamine (chemical messenger in the brain) primarily used in the treatment of Parkinson’s disease with its symptoms including tremors, spasms, muscle stiffness, and poor muscle control. Parkinson’s disease is a disorder of the central nervous system that affects movement and locomotion, which causes stiffness, shaking, difficulty in walking, coordination, and balance. In Parkinson's patients, there are low dopamine levels as the nerve cells of the brain (neurons) that produce dopamine begin to die.
Carbidopa+levodopa contains 'Levodopa' and 'Carbidopa'. Levodopa belongs to the central nervous system agents, while Carbidopa is a decarboxylase inhibitor. The medicinal component Levodopa changes into dopamine in the brain and helps to control movement. Carbidopa acts by preventing the breakdown of Levodopa in the bloodstream so that more Levodopa can reach to brain.
