What Levodopa / Benserazide ratiopharm is and what it is used for

Levodopa / Benserazide Ratiopharm is used for treating Parkinson’s disease.

The cause of the symptoms of Parkinson’s disease is a lack of dopamine in certain parts of the brain. Dopamine is a substance that transmits nerve signals.
Parkinson’s disease is a lifelong disease and treatment must last a lifetime. Dopamine must be added to alleviate the prevalent deficiency. Dopamine can not reach the brain from other parts of the body, but it can levodopa which in the brain cells is converted to dopamine.
Levodopa / Benserazide Ratiopharm includes levodopa together with benserazide, a substance that prevents levodopa from being converted to dopamine out in the body but allows the transformation to take place in the brain. This largely avoids the unwanted effects of dopamine on the body’s other organs.
Levodopa / Benserazide Ratiopharm relieves many of the symptoms that are characteristic of Parkinson’s disease; tremors, muscle stiffness, slow movements, and difficulty starting movements, difficulty swallowing, difficulty maintaining balance, abnormally large salivary secretion.

Levodopa and benserazide contained in Levodopa / Benserazide Ratiopharm may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or other healthcare professional if you have any further questions, and always follow their instructions.
