Sinemet C is a sustained-release combination of carbidopa and levodopa for the treatment of Parkinson’s disease and syndrome.

How does it work?

This pharmaceutical preparation is a combined antiparkinsonian drug of a systemic nature.

The main active substances are levodopa and carbidopa. These substances belong to dopaminergic drugs. Levodopa is a metabolic precursor of dopamine. Carbidopa, in turn, is a substance that has the ability to inhibit peripheral dopa-decarboxylase. Levodopa also has the property of stopping the symptoms of Parkinson’s disease due to metabolic processes, including decarboxylation of the brain.

Carbidopa, in turn, promotes the penetration of levodopa into the brain, as well as its conversion to dopamine. If carbidopa is not present in the preparation, then a significantly larger amount of levodopa must be used to provide the expected effect.

The dug reduces impaired motor reactions, dyskinesia and hyperkinesia. The effect is observed from the first days of therapy.

Composition and release form

The main active components: levodopa, carbidopa.

Auxiliary substances: starch, lactose, cellulose, magnesium stearate, etc.

The drug is produced in tablet form. Each tablet contains 250 mg of levodopa and 25 mg of carbidopa.
