Table of contents:

Prolopa is a combination medication used to treat the symptoms of Parkinson's disease. It is a combination medication that contains two active ingredients - levodopa and benserazide.

Levodopa is a precursor to the neurotransmitter dopamine, a chemical in the brain that is responsible for controlling movement. When taken orally, levodopa crosses the blood-brain barrier and is converted into dopamine in the brain, which helps to alleviate the symptoms of Parkinson's disease. However, much of the levodopa in the body is converted into dopamine in peripheral tissues before it can cross the blood-brain barrier, which can cause side effects.

Benserazide, on the other hand, is an inhibitor of the enzyme that converts levodopa into dopamine in peripheral tissues, which helps to increase the amount of levodopa that reaches the brain and reduces the risk of side effects.

Together, levodopa and benserazide work to increase dopamine levels in the brain, which helps to alleviate the symptoms of Parkinson's disease such as tremors, muscle stiffness, and slow movements.

Use and Dosage

Prolopa is taken orally in the form of capsules, with food as directed by the doctor, usually 4 to 6 times a day. The capsules should be swallowed whole and should not be opened or dissolved in any liquid. Avoid a high-protein diet during treatment, unless directed otherwise by your doctor. Iron supplements or products containing iron (such as multivitamins with minerals) should be taken at separate times, as iron can reduce the amount of levodopa absorbed by the body.

The dosage of Prolopa is based on the patient's medical condition and response to treatment. To reduce the risk of side effects, the doctor may direct the patient to start with a low dose and gradually increase it according to their instructions.

Some patients may experience a "wearing-off" (worsening of symptoms) before the next dose is due, or an "on-off" effect with sudden short periods of stiffness. If these effects occur, the doctor should be contacted for possible dose adjustments.

Prolopa should not be stopped suddenly without consulting the doctor, as doing so may cause withdrawal symptoms such as anxiety, depression, confusion, fever, and muscle stiffness. To prevent withdrawal, the doctor may lower the dose gradually, especially if the medication has been used for a long time or in high doses. If withdrawal symptoms occur, the doctor or pharmacist should be informed immediately.
