Carbidopa and Levodopa Tablets 25 mg/100 mg, 100 Count (RX)

Carbidopa and Levodopa Tablets 25 mg/100 mg by Teva Pharmaceuticals are a combination medication used to treat symptoms of Parkinson's disease, such as tremors, stiffness, and difficulty with movement. Carbidopa helps prevent the breakdown of levodopa in the body, allowing more of it to reach the brain where it is converted into dopamine - a chemical that is lacking in Parkinson's disease. This combination tablet is manufactured by Teva Pharmaceuticals and contains 25 mg of carbidopa and 100 mg of levodopa. It may be prescribed by a doctor as part of an overall treatment plan for Parkinson's disease.

Parkinson's disease is a progressive, neurodegenerative disorder of the extrapyramidal nervous system affecting the mobility and control of the skeletal muscular system. Its characteristic features include resting tremor, rigidity, and bradykinetic movements. Symptomatic treatments, such as levodopa therapies, may permit the patient better mobility.Current evidence indicates that symptoms of Parkinson's disease are related to depletion of dopamine in the corpus striatum. Administration of dopamine is ineffective in the treatment of Parkinson's disease apparently because it does not cross the blood- brain barrier. However, levodopa, the metabolic precursor of dopamine, does cross the blood-brain barrier, and presumably is converted to dopamine in the brain. This is thought to be the mechanism whereby levodopa relieves symptoms of Parkinson's disease.
