Madopar Cr (Benserazide, Levodopa)

Levodopa, the active ingredient in Madopar CR, is a dopamine precursor presented as a controlled‑release tablet for oral use. It treats Parkinson's disease by replenishing central dopamine in patients with this neurodegenerative disorder, helping to improve motor function and reduce rigidity and tremor. The formulation ensures steady plasma concentrations over several hours, which can lessen the frequency of dosing compared with immediate‑release preparations.

GNH India supplies Madopar CR as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, providing reliable sourcing, regulatory support and logistics for global healthcare providers and after‑sales service.

Indications & Clinical Uses

Madopar CR is used in the management of Parkinsonian disorders, targeting the dopaminergic pathway to improve motor symptoms.

  • Parkinson's disease: improves motor control, reducing rigidity and tremor.
  • Parkinsonian syndrome: alleviates bradykinesia and gait disturbances.
  • Motor fluctuations in Parkinson's disease: provides more stable symptom control throughout the day.

How It Works

  • Levodopa crosses the blood‑brain barrier and is decarboxylated to dopamine, directly replenishing depleted central dopamine stores. Benserazide, a peripheral DOPA decarboxylase inhibitor, prevents conversion of levodopa outside the brain, thereby increasing the amount of levodopa that reaches the central nervous system and enhancing its therapeutic effect.

Side Effects

Levodopa/Benserazide may cause a range of adverse reactions, which are grouped by frequency.

Common Side Effects

  • Nausea: upset stomach often occurring at treatment initiation.
  • Dizziness: light‑headedness, especially when standing quickly.
  • Orthostatic hypotension: drop in blood pressure upon standing.
  • Headache: mild to moderate intensity.
  • Insomnia: difficulty falling or staying asleep.
  • Dyskinesia: involuntary movements, especially with higher doses.

Serious or Rare Side Effects

  • Hallucinations or psychosis: visual or auditory disturbances requiring medical review.
  • Severe hypotension: marked blood pressure drop that may cause fainting.
  • Cardiac arrhythmias: irregular heart rhythms observed in susceptible patients.
  • Anaphylactic reaction: rare but potentially life‑threatening allergy.

Precautions & Warnings

When prescribing Madopar CR, several safety considerations should be observed.

  • Renal impairment: adjust dose or monitor closely.
  • Hepatic impairment: use with caution and monitor liver function.
  • Cardiovascular disease: monitor blood pressure and heart rate.
  • History of melanoma or other cancers: evaluate risk versus benefit.
  • Concomitant MAO‑B inhibitors: avoid use within 14 days of stopping.
  • Pregnancy and breastfeeding: safety not established; prescribe only if essential.
  • Store at ambient temperature: keep in original container, protect from moisture and light.

Avoid Interactions

Madopar CR can interact with other medicines, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid)

  • Non‑selective MAO inhibitors: risk of hypertensive crisis.
  • Antipsychotic agents (e.g., haloperidol): may diminish therapeutic effect.
  • High‑protein meals: can reduce levodopa absorption and efficacy.

Moderate Interactions (Monitor Closely)

  • Selective MAO‑B inhibitors (selegiline, rasagiline): may increase levodopa levels.
  • Antihypertensive drugs: additive hypotensive effect.
  • SSRIs or SNRIs: potential for serotonin syndrome when combined with MAO‑B inhibitors.

Frequently Asked Questions

Madopar CR is prescribed for the treatment of Parkinson's disease. It helps to restore dopamine levels in the brain, which can improve motor symptoms such as tremor, rigidity, and bradykinesia, and may also reduce the frequency of motor fluctuations experienced by patients.

Levodopa is a precursor of dopamine that crosses the blood‑brain barrier. Once inside the central nervous system, it is converted into dopamine, directly replenishing the neurotransmitter that is deficient in Parkinson's disease. This increase in dopamine improves motor control and reduces characteristic Parkinsonian symptoms.

The dose of Madopar CR is individualized for each patient. A qualified prescriber determines the appropriate starting dose, titration schedule, and maintenance dose based on the patient's clinical response, disease severity, and tolerability. Specific dosing regimens should be obtained from the prescribing clinician.

Safety of Madopar CR during pregnancy and lactation has not been established. It should only be used when the potential benefit to the mother outweighs any possible risk to the fetus or infant, and this decision must be made by the treating physician.

To place an order, submit an enquiry on the Madopar CR product page at gnhindia.com, specifying the required quantity. GNH India supplies hospitals, pharmacies and procurement teams worldwide, and will request verification of trade or institutional credentials before providing pricing, availability, shipping details and import documentation.

Madopar CR provides a controlled‑release delivery that maintains steadier plasma levodopa concentrations over several hours, potentially reducing dosing frequency and minimizing peaks and troughs associated with immediate‑release tablets. This can lead to smoother symptom control and may lessen the occurrence of motor fluctuations in some patients.

Madopar CR tablets should be stored at ambient temperature, below 25 °C. Keep them in the original packaging, protect from moisture and direct light, and ensure the container is tightly closed to maintain tablet integrity throughout its shelf life.

Madopar CR is taken orally. The tablet should be swallowed whole with a glass of water and not chewed, crushed, or split, as altering the tablet can disrupt the controlled‑release mechanism and affect drug absorption.

Serious adverse reactions include hallucinations or psychosis, severe hypotension that may cause fainting, cardiac arrhythmias, and rare anaphylactic reactions. Patients should seek immediate medical attention if they experience sudden confusion, severe dizziness, palpitations, or signs of an allergic response.

Madopar CR is contraindicated in patients with known hypersensitivity to levodopa, benserazide, or any excipients of the tablet. It should also be avoided in individuals taking non‑selective MAO inhibitors, or in those with narrow‑angle glaucoma, malignant melanoma, or severe cardiovascular disease without careful medical supervision.
