Generic Stalevo Information

Introduction

Stalevo is a fixed‑dose combination medication indicated for the management of idiopathic Parkinson’s disease in adults. It combines three pharmacologically active agents—levodopa, carbidopa, and entacapone—designed to increase central dopaminergic activity while reducing peripheral side effects and extending the duration of levodopa action. In Hong Kong, Stalevo is prescribed when patients experience motor fluctuations that cannot be adequately controlled with levodopa alone. The product is marketed by Novartis and is classified under the therapeutic groups of mental illness and Parkinson’s disease.

What is Stalevo?

Stalevo is a tablet formulation that contains the three active compounds levodopa, carbidopa, and entacapone in a single dosage unit. Levodopa is a dopamine precursor that crosses the blood–brain barrier; carbidopa is a peripheral dopa‑decarboxylase inhibitor that prevents the premature conversion of levodopa to dopamine outside the central nervous system; entacapone is a catechol‑O‑methyltransferase (COMT) inhibitor that blocks the metabolic inactivation of levodopa, thereby prolonging its plasma half‑life. The combination is manufactured by Novartis and approved by the Hong Kong Department of Health under the same brand name. Generic versions containing the identical active ingredients are also available from licensed overseas suppliers. Our online pharmacy provides these generic alternatives at a cost comparable to the manufacturer’s price while maintaining the same therapeutic efficacy.

How Stalevo Works

Levodopa entered the brain via the large neutral amino‑acid transporter, where aromatic L‑amino‑acid decarboxylase converts it to dopamine, restoring deficient neurotransmission in the basal ganglia. Carbidopa, which does not cross the blood–brain barrier, inhibits peripheral decarboxylation, allowing a larger proportion of the administered levodopa to reach the brain and reducing peripheral adverse effects such as nausea and orthostatic hypotension. Entacapone inhibits COMT, an enzyme responsible for methylating levodopa to 3‑O‑methyldopa in the periphery. By blocking this pathway, entacapone reduces the formation of inactive metabolites, prolongs the plasma concentration of levodopa, and smooths the “on‑off” motor fluctuations that many patients experience after chronic levodopa therapy. The combined effect is a more consistent dopaminergic stimulation, leading to improved motor control and reduced dosing frequency.

Conditions Treated with Stalevo

• Idiopathic Parkinson’s disease (PD) – Stalevo is approved for patients with early‑stage PD who are levodopa‑responsive, as well as for those with advanced disease who experience wearing‑off phenomena.
• Motor fluctuations – In patients whose response to levodopa becomes erratic (e.g., “on” periods followed by “off” periods), the addition of entacapone stabilises plasma levodopa levels and reduces the frequency of off‑episodes.

In Hong Kong, an estimated 13,000 individuals are diagnosed with Parkinson’s disease, and the prevalence rises with age. As the population ages, demand for therapies that minimize motor complications while preserving quality of life continues to increase, positioning Stalevo as a cornerstone of modern PD management.

Suitable Candidates for Stalevo Treatment

• Adults with confirmed idiopathic Parkinson’s disease who are already on a stable levodopa regimen but exhibit motor fluctuations, dyskinesia, or reduced “on” time.
• Patients who tolerate levodopa and carbidopa but require an adjunct to extend levodopa’s effect without increasing the levodopa dose.
• Individuals with early‑stage disease who are expected to need long‑term dopaminergic therapy and for whom a single‑tablet regimen may improve adherence.
• Patients without contraindications such as hypersensitivity to any component, severe hepatic impairment, or a history of neuroleptic malignant syndrome.

Stalevo is not appropriate for:

• Patients with narrow‑angle glaucoma, because dopaminergic agents can increase intra‑ocular pressure.
• Individuals taking non‑selective monoamine oxidase inhibitors (MAO‑Is) or selective MAO‑B inhibitors (e.g., selegiline) without appropriate washout periods, due to the risk of hypertensive crises.
• Those with significant renal dysfunction (creatinine clearance <30 mL/min) where dosage adjustments and close monitoring are required.

Risks, Side Effects, and Interactions

Common

• Nausea, vomiting, or abdominal discomfort
• Dry mouth
• Dizziness or light‑headedness, especially when standing (orthostatic hypotension)
• Dyskinesia (untary movements) during “on” periods
• Diarrhoea or constipation

Rare

• Hallucinations or psychotic symptoms, particularly in older patients or those with pre‑existing cognitive impairment
• Urinary retention or incontinence
• Serotonin syndrome when combined with serotonergic agents (e.g., SSRIs, SNRIs)

Serious

• Severe hypertension or hypertensive crisis, especially when entacapone is taken with non‑selective MAO inhibitors
• Neuroleptic malignant syndrome‑like reactions (hyperthermia, muscle rigidity) if combined with antipsychotics that block dopamine receptors
• Hepatic impairment: entacapone is metabolised in the liver; rare cases of hepatotoxicity have been reported

Clinically Relevant Drug–Drug Interactions

• MAO inhibitors – Avoid concurrent use with non‑selective MAO‑A or MAO‑B inhibitors; a minimum 14‑day washout is required.
• Anticholinergics – May exacerbate dry mouth and constipation.
• Antipsychotics (e.g., haloperidol, risperidone) – Can antagonise the dopaminergic effect of levodopa, reducing clinical benefit and precipitating severe motor worsening.
• Serotonergic antidepressants – Co‑administration can increase the risk of serotonin syndrome; monitor for agitation, fever, or hyperreflexia.

Patients should disclose all prescribed, over‑the‑counter, and herbal products to their healthcare provider before initiating Stalevo.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing – The usual adult starting dose is one tablet containing 100 mg levodopa, 25 mg carbidopa, and 200 mg entacapone, taken three times daily with meals. Dosage may be titrated in 50‑mg levodopa increments based on clinical response and tolerability, up to a maximum of eight tablets per day.
• Missed dose – If a dose is missed and the scheduled time for the next dose is more than 3 hours away, take the missed tablet as soon as remembered. If the next dose is imminent, skip the missed tablet and resume the regular dosing schedule; do not double‑dose.
• Overdose – Symptoms may include severe nausea, vomiting, hyperthermia, confusion, or cardiac arrhythmias. Seek emergency medical attention immediately. Management is primarily supportive, with gastric decontamination if presentation is early and close monitoring of cardiovascular status.
• Food considerations – High‑protein meals can compete with levodopa for intestinal transport, reducing absorption. It is advisable to take Stalevo with a moderate protein intake and avoid large protein‑rich meals immediately before dosing.
• Alcohol – Moderate alcohol consumption does not markedly affect Stalevo’s efficacy but may exacerbate dizziness or orthostatic hypotension; patients should limit intake and monitor symptoms.
• Comorbidities – In patients with hepatic or renal impairment, dose reductions and more frequent monitoring of liver enzymes and renal function are recommended.

FAQ

• Can Stalevo be taken with other Parkinson’s medications such as rasagiline?
  Yes, Stalevo may be co‑administered with selective MAO‑B inhibitors like rasagiline, provided an appropriate wash‑out period from non‑selective MAO inhibitors has been observed. Clinical guidance recommends monitoring for signs of hypertension or serotonin excess.

• Is a dose adjustment needed for elderly patients with Parkinson’s disease?
  Older adults often have reduced renal and hepatic clearance and may be more sensitive to dopaminergic side effects. Starting at a lower dose (e.g., one tablet three times daily) and titrating slowly is standard practice.

• What should I do if I experience sudden severe nausea after taking Stalevo?
  Severe nausea may indicate excessive peripheral dopamine. Contact a healthcare professional for possible dose reduction or addition of an anti‑emetic such as domperidone, which does not cross the blood–brain barrier.

• Does Stalevo require special storage conditions in Hong Kong’s humid climate?
  Store tablets at room temperature (20‑25 °C) away from direct sunlight, moisture, and heat. Use a sealed container to protect against humidity, especially in high‑humidity seasons.

• Are there any differences between the brand‑name and generic tablets in terms of appearance?
  Brand‑name Stalevo tablets are typically bicolour, pink and white, scored for easy splitting. Generic versions may vary in colour and imprint but contain the same active ingredients and meet identical regulatory standards.

• Can I travel internationally with Stalevo in my carry‑on luggage?
  Yes, Stalevo can be taken in hand luggage. Keep the medication in its original packaging with a copy of the prescription (if required) and declare it at customs if asked.

• How long does it take for Stalevo to start improving motor symptoms?
  Clinical trials show that patients usually notice an improvement in “on” time within 1–2 weeks of initiation, with maximal benefit observed after 4–6 weeks of stable dosing.

• Is Stalevo compatible with dietary supplements such as vitamin B12?
  Vitamin B12 does not interfere with the pharmacokinetics of Stalevo. However, high‑dose antioxidant supplements should be discussed with a clinician, as they may influence oxidative stress pathways involved in Parkinson’s disease.

• What are the most common reasons for switching from levodopa alone to Stalevo?
  The primary reasons include wearing‑off phenomena, reduced “on” time, and the need to limit levodopa dose escalation. Adding entacapone prolongs levodopa’s effect, reducing motor fluctuations.

• Are there any known ethnic differences in Stalevo metabolism for Asian populations?
  Pharmacogenetic studies suggest modest variations in COMT activity across ethnic groups, but standard dosing is generally appropriate for Hong Kong patients. Clinicians may monitor therapeutic response and adjust dose individually.

Glossary

Levodopa

A synthetic precursor of dopamine that crosses the blood–brain barrier and is converted to dopamine in central nervous system neurons, thereby restoring deficient dopaminergic transmission in Parkinson’s disease.

Carbidopa

A peripheral dopa‑decarboxylase inhibitor that prevents the conversion of levodopa to dopamine outside the brain, increasing levodopa’s availability to the central nervous system and reducing peripheral side effects.

Entacapone

A catechol‑O‑methyltransferase (COMT) inhibitor that blocks the enzymatic breakdown of levodopa in the periphery, extending its plasma half‑life and smoothing motor fluctuations.

Wearing‑off phenomenon

The re‑emergence of Parkinsonian symptoms before the next scheduled dose of levodopa, indicating a shortening of the drug’s therapeutic window.
