Generic Requip Information

Introduction

Requip is a prescription medicine used primarily to improve motor control in people with Parkinson’s disease. It contains the active compound ropinirole, a dopamine‑receptor agonist that mimics the action of dopamine in the brain. In the United Kingdom the drug is marketed by Pfizer and is listed on the NHS formulary for both Parkinson’s disease and restless‑legs syndrome (RLS), a condition that causes uncomfortable urges to move the legs. Its availability through specialist clinics makes it a central option for patients who need additional symptom control beyond levodopa therapy.

What is Requip?

Requip is a tablet formulation of ropinirole hydrochloride. It belongs to the class of dopamine agonists and was developed to provide continuous dopaminergic stimulation for patients with Parkinsonian motor symptoms. Pfizer holds the marketing authorisation for the brand‑name product in the UK, while the same active ingredient is also supplied by other manufacturers as generic ropinirole. The medication is supplied as immediate‑release tablets in strengths of .25 mg, .5 mg, 1 mg, 2 mg, 4 mg and 8 mg.

How Requip Works

Ropinirole binds selectively to dopamine D2‑like receptors (mainly D2 and D3) in the basal ganglia. By stimulating these receptors, it compensates for the dopamine deficiency that characterises Parkinson’s disease. The drug’s effect begins within 30 minutes after oral ingestion, reaches peak plasma concentrations in about 1–2 hours, and has an elimination half‑life of roughly 6 hours. This pharmacokinetic profile allows for three‑times‑daily dosing, providing relatively steady dopaminergic activity throughout the day and reducing motor “off” periods.

Conditions Treated with Requip

• Parkinson’s disease (adjunct to levodopa) – Requip is indicated for patients whose motor symptoms are not fully controlled by levodopa alone, helping to reduce “off” episodes and improve overall mobility. In the UK an estimated 145,000 people live with Parkinson’s disease, and dopaminergic adjuncts are a core component of treatment algorithms.
• Restless‑legs syndrome (RLS) – The drug reduces the uncomfortable urge to move the legs and improves sleep quality. RLS affects up to 5 % of the UK adult population, with a higher prevalence among women and the elderly.
• Off‑label or investigational use – In some specialist centres ropinirole is explored for augmentation of antipsychotic regimens or for certain types of focal dystonia, but these uses are not formally approved in the UK.

Who is Requip For?

Requip is suitable for adult patients (generally >18 years) who have:

• A confirmed diagnosis of Parkinson’s disease with motor fluctuations despite optimal levodopa dosing.
• Moderate to severe restless‑legs syndrome that has not responded adequately to non‑pharmacological measures.

The medication is not recommended for:

• Individuals with a known hypersensitivity to ropinirole or any tablet excipients.
• Patients with uncontrolled psychiatric illness (e.g., active psychosis) because dopamine agonists can exacerbate hallucinations.
• Those with severe hepatic impairment (Child‑Pugh C) or end‑stage renal disease not on dialysis, unless dose adjustments are made under specialist supervision.

Risks, Side Effects, and Interactions

Common

• Nausea and vomiting
• Dizziness or light‑headedness (especially on standing)
• Somnolence or insomnia
• Headache
• Dry mouth

Rare

• Peripheral edema
• Orthostatic hypotension leading to fainting
• Hallucinations or vivid dreams
• Dyskinesia (in patients already on levodopa)

Serious

• Sudden onset of compulsive behaviours such as gambling, hypersexuality, or excessive shopping
• Severe hypotension with syncope
• Allergic reactions: rash, pruritus, facial swelling, or anaphylaxis

Drug–drug interactions

• MAO‑B inhibitors (e.g., selegiline, rasagiline) – additive dopaminergic effect may increase risk of hypertension.
• Antipsychotics (e.g., haloperidol, risperidone) – may antagonise ropinirole’s action, reducing efficacy.
• CYP1A2 inhibitors (e.g., fluvoxamine, ciprofloxacin) – can raise ropinirole plasma levels, raising the likelihood of side effects.
• CYP1A2 inducers (e.g., smoking, carbamazepine) – may lower drug concentrations, reducing therapeutic benefit.

Patients should disclose all concurrent medications, including over‑the‑counter products and herbal supplements, to the prescribing clinician.

Practical Use: Dosing, Missed Dose, Overdose

• Parkinson’s disease – Initiate with .25 mg three times daily. Increase by .25 mg–.5 mg every 3–5 days until the desired clinical response is achieved, generally not exceeding 8 mg per day.
• Restless‑legs syndrome – Start with .25 mg taken after the evening meal. After 3 days, the dose may be increased to .5 mg; further increments of .5 mg are possible at weekly intervals up to a maximum of 4 mg/day.

Missed dose – If a dose is forgotten and the scheduled time is more than 4 hours away, skip the missed dose and resume the regular dosing schedule. Do not double‑dose to compensate.

Overdose – Symptoms may include profound nausea, vomiting, severe dizziness, or loss of consciousness. If an overdose is suspected, seek urgent medical attention; treatment is supportive, focusing on symptom control and monitoring of cardiovascular status.

Precautions

• Take tablets with food or a light snack to minimise gastrointestinal upset.
• Alcohol can enhance somnolence; limit intake.
• Patients with cardiovascular disease should be monitored for orthostatic hypotension.
• Dose adjustments may be required in moderate hepatic impairment (reduce by 25 %) and in renal impairment (creatinine clearance <30 mL/min, consider dose reduction).

FAQ

• Is Requip available in both brand‑name and generic forms in the UK?
  Yes. The brand‑name product is marketed as Requip by Pfizer, while the same active ingredient, ropinirole, is also sold under generic names by several licensed manufacturers. Generic versions contain identical amounts of ropinirole and are generally less expensive.

• What is the typical appearance of a Requip tablet?
  Requip tablets are round, film‑coated, and colour‑coded by strength: .25 mg (white), .5 mg (light pink), 1 mg (blue), 2 mg (green), 4 mg (yellow), and 8 mg (orange). Each tablet is imprinted with “R” and the dosage strength on one side.

• Does Requip require refrigeration?
  No. Requip should be stored at controlled room temperature, between 15 °C and 30 °C, away from direct sunlight and moisture. Refrigeration is not necessary and may affect tablet integrity.

• Can I travel internationally with Requip tablets?
  You may carry Requip for personal use when travelling, provided you keep the medication in its original packaging with a copy of the prescription label. Some countries impose limits on the quantity that can be imported, so it is advisable to check local customs regulations before departure.

• Are there notable differences between ropinirole formulations in the EU and the US?
  The active ingredient and approved indications are the same, but tablet sizes, excipients, and colour‑coding can vary. In the EU, the tablets are generally film‑coated and contain lactose, whereas some US formulations may use different binders. These variations do not alter the therapeutic effect but may be relevant for patients with specific allergies.

• What are the inactive ingredients in Requip tablets?
  In addition to ropinirole hydrochloride, Requip tablets contain lactose monohydrate, maize starch, magnesium stearate, and a film‑coating polymer (polyvinyl acetate). Patients with lactose intolerance should discuss alternatives with their clinician.

• Is there a history of regulatory warnings for Asian populations taking ropinirole?
  The European Medicines Agency (EMA) has not issued ethnicity‑specific warnings for ropinirole. However, studies suggest that certain Asian subpopulations may experience higher plasma concentrations due to genetic variations in CYP1A2 metabolism, possibly increasing the risk of side effects. Dose adjustments may be considered on an individual basis.

• Can Requip affect drug testing for employment or sports?
  Ropinirole is not listed as a prohibited substance by major sporting agencies such as WADA. Standard occupational drug screens typically do not include ropinirole, so its presence is unlikely to influence most drug‑testing outcomes.

• What major clinical trials established the efficacy of ropinirole for RLS?
  Two pivotal Phase III trials (the 1999 and 2002 studies) demonstrated that ropinirole .5–4 mg daily significantly reduced the International RLS Study Group rating scale scores compared with placebo. These studies formed the basis for regulatory approval in both the EU and the US.

• How does ropinirole compare with other dopamine agonists such as pramipexole?
  Both drugs act on D2/D3 receptors, but ropinirole has a shorter half‑life, requiring three‑times‑daily dosing, whereas pramipexole can be dosed once or twice daily. Side‑effect profiles are similar, though ropinirole may cause slightly more nausea, while pramipexole is associated with a higher incidence of somnolence. Choice of agent often depends on patient preference, tolerability, and dosing convenience.

• Is it safe to crush or split Requip tablets?
  Immediate‑release ropinirole tablets may be split only if the tablet is scored (e.g., 2 mg tablets). Crushing is not recommended because it can affect absorption and increase the risk of side‑effects, especially nausea. If splitting is required for dose adjustment, discuss it with a pharmacist first.
