Generic Nimotop Information

Introduction

Nimotop (generic name : nimodipine) is a calcium‑channel blocker classified within the cardiovascular therapeutic group. It is principally prescribed to reduce the risk of cerebral vasospasm and delayed neurological deficits following aneurysmal subarachnoid haemorrhage (SAH). In Hong Kong, the drug is listed under the Hospital Authority formulary for neurosurgical patients and may also be obtained through licensed pharmacies for off‑label uses that are supported by clinical evidence, such as certain types of chronic migraine and vasospastic disorders. The active compound, nimodipine, exerts selective vasodilatory effects on cerebral arteries while having limited impact on systemic blood pressure, which makes it especially valuable in neurovascular care.

What is Nimotop?

Nimotop is a brand name for the oral formulation of nimodipine, a dihydropyridine calcium‑channel antagonist. It was originally developed by Bayer AG and launched under the trade name Nimotop®. The medication is supplied as film‑coated tablets containing 30 mg of nimodipine each. Although Nimotop is the commercial brand, the same active ingredient is available from other manufacturers under generic names, enabling cost‑effective therapy without compromising efficacy.

Nimotop is the generic version of the original brand Nimodipine, containing the same active compound nimodipine. Our online pharmacy provides this generic alternative as a cost‑effective treatment option.

How Nimotop Works

Nimodipine blocks L‑type voltage‑gated calcium channels predominantly located in the smooth muscle of cerebral arteries. By inhibiting calcium influx, it reduces vascular smooth‑muscle contraction, leading to vasodilation of the small‑diameter intracranial vessels. The resulting increase in cerebral blood flow helps to prevent the narrowing (vasospasm) that frequently follows SAH.

Key pharmacologic points:

• Onset of action: Clinical vasodilatory effects are observed within 30‑60 minutes after oral administration.
• Peak plasma concentration: Reached at approximately 1–2 hours post‑dose.
• Half‑life: 8–12 hours in adults with normal hepatic function, supporting a twice‑daily dosing schedule.
• Metabolism and excretion: Extensively metabolised by hepatic cytochrome P450 3A4; metabolites are eliminated primarily via the bile. Renal excretion is minimal, which reduces dose adjustment in mild to moderate renal impairment.

The selective cerebral vasodilation, coupled with a modest systemic effect, underpins its therapeutic benefit in preventing delayed cerebral ischemia after SAH.

Conditions Treated with Nimotop

• Aneurysmal Subarachnoid Haemorrhage (SAH):

  • Primary indication approved by the US FDA, European Medicines Agency, and Hong Kong’s Department of Health. Clinical trials demonstrate that nimodipine reduces the incidence of delayed cerebral ischemia from ≈30 % to ≈15 % and improves functional outcome at 3 months.
  • In Hong Kong, SAH accounts for roughly 7 % of all strokes, translating to several hundred cases annually; nimodipine is therefore a cornerstone of neurocritical care.

• Cerebral Vasospasm of Non‑Aneurysmal Origin:

  • Off‑label use in reversible cerebral vasoconstriction syndrome (RCVS) and post‑traumatic vasospasm is supported by case series indicating favorable cerebral perfusion responses.

• Migraine Prophylaxis (Selected Patients):

  • Small randomized studies have shown reduction in migraine frequency when nimodipine is added to conventional prophylactic agents, likely due to its cerebral vasodilatory properties.

• Peripheral Vascular Disease (Adjunctive Use):

  • Limited evidence suggests benefit in improving microcirculatory flow in lower‑extremity claudication, though this remains an experimental indication.

Who is Nimotop For?

Nimotop is most appropriate for adult patients who meet the following criteria:

• Confirmed aneurysmal SAH within 72 hours of symptom onset, regardless of age, provided there are no contraindications to calcium‑channel blockade.
• Patients undergoing neurosurgical clipping or endovascular coiling where prevention of delayed cerebral ischemia is critical.
• Individuals with documented cerebral vasospasm on transcranial Doppler or angiography, who have not responded adequately to conventional therapies such as hypertensive hypervolemic therapy.
• Select migraine sufferers who have failed first‑line prophylactic agents and have been evaluated by a neurologist for off‑label use.

Contraindications / situations where nimodipine is not appropriate:

• Known hypersensitivity to nimodipine or any dihydropyridine calcium‑channel blocker.
• Severe hepatic impairment (Child‑Pugh C) because metabolism is reduced, increasing systemic exposure.
• Uncontrolled hypotension (systolic blood pressure < 90 mmHg) as further vasodilation may compromise cerebral perfusion pressure.
• Concurrent use of potent CYP3A4 inhibitors (e.g., clarithromycin, ritonavir) without dose adjustment, due to risk of elevated plasma levels.

Risks, Side Effects, and Interactions

Common

• Headache – often mild and transient, may reflect cerebral vasodilation.
• Dizziness or light‑headedness – related to modest systemic blood‑pressure reduction.
• Flushing – warm sensation, usually resolves with continued therapy.
• Nausea / gastrointestinal upset – may be reduced by taking tablets with food.

Rare

• Hypotension – systolic pressure drop > 20 mmHg, uncommon at standard doses but more likely in elderly or volume‑depleted patients.
• Bradycardia – heart rate < 50 bpm, reported in isolated case reports.
• Peripheral edema – mild swelling of the ankles, typically reversible after discontinuation.

Serious

• Severe hypotensive shock – exceedingly rare; requires immediate medical attention.
• Allergic reactions – anaphylaxis, angio‑edema, or severe skin rash; discontinue drug and seek emergency care.
• Liver enzyme elevation – transaminases may rise > 3 × ULN; monitor liver function in patients with pre‑existing hepatic disease.

Drug–Drug Interactions

• CYP3A4 inhibitors (e.g., ketoconazole, erythromycin, HIV protease inhibitors) → increase nimodipine plasma concentration, heightening risk of hypotension and dizziness.
• CYP3A4 inducers (e.g., carbamazepine, rifampicin, St. John’s wort) → reduce efficacy by accelerating metabolism; dose adjustment may be required.
• Other antihypertensives (e.g., beta‑blockers, ACE inhibitors) → additive blood‑pressure‑lowering effect; monitor hemodynamics.
• Antacids containing aluminium or magnesium → may modestly reduce oral absorption; separate administration by at least 2 hours is advisable.

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

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing for SAH: 60 mg orally every 4 hours (total 360 mg per day) for 21 days, beginning within 24 hours of aneurysm securing.
• Off‑label migraine or vasospasm: 30 mg twice daily is commonly used, though dosing should be individualized by a qualified clinician.

Administration tips

• Tablets should be taken with food or milk to improve gastrointestinal tolerance.
• Swallow whole; do not crush or chew, as this can increase peak concentration and adverse effects.

Missed dose

• If a dose is missed within 2 hours, take it as soon as remembered.
• If the next scheduled dose is imminent, skip the missed dose and continue the regular schedule. Do not double‑dose.

Overdose

• Symptoms may include severe hypotension, profound dizziness, and syncope.
• Immediate medical evaluation is required; supportive care with intravenous fluids and vasopressors may be necessary.
• No specific antidote exists; management is symptomatic and based on vital‑sign monitoring.

Precautions

• Avoid excessive alcohol consumption, which can potentiate hypotensive effects.
• Patients with congestive heart failure should be monitored closely for fluid overload, as nimodipine can cause mild peripheral vasodilation.
• Renal impairment does not usually require dose modification, but hepatic function should be assessed before initiation.

FAQ

• Is nimodipine available in both brand‑name and generic forms in Hong Kong?
  Yes. The original brand, Nimotop®, is registered with the Hong Kong Department of Health, and several local distributors also market generic nimodipine tablets that contain the same 30 mg active ingredient.

• Does Nimotop require refrigeration or special storage conditions?
  No. Nimotop tablets should be stored at controlled room temperature (15 °C – 30 °C), protected from moisture, direct sunlight, and heat sources. A bathroom cabinet is not recommended because humidity can degrade the film coating.

• What does the film coating of Nimotop tablets look like?
  The tablets are round, bicolour (light‑blue core with a dark‑blue coating), and each bears the imprint “30 mg NIMO”. The coating is designed to mask the bitter taste of nimodipine and to facilitate swallowing.

• Can Nimotop be taken with grapefruit juice?
  Grapefruit juice strongly inhibits CYP3A4 enzymes in the intestinal wall, potentially raising nimodipine plasma levels and increasing the risk of hypotension. Patients are advised to avoid large quantities of grapefruit or its juice while on Nimotop.

• Are there any travel restrictions for bringing Nimotop into Hong Kong?
  Personal import of up to a 30‑day supply of prescription‑only medicines is permitted under Hong Kong customs regulations, provided the medication is for personal use and is declared if requested. Carry a copy of the prescription or a doctor’s note to avoid customs delays.

• How long does a typical shipment from our online pharmacy take to arrive in Hong Kong?
  Express shipping usually arrives within 7 business days to any address on Hong Kong Island, Kowloon, or the New Territories. Standard airmail may require up to 3 weeks, depending on customs clearance and carrier schedules.

• Does Nimotop contain any allergens or excipients that could cause reactions?
  In addition to nimodipine, the tablet contains lactose, magnesium stearate, and povidone. Patients with known lactose intolerance or hypersensitivity to any of these excipients should discuss alternative formulations with their healthcare provider.

• What clinical trial established the efficacy of Nimotop for subarachnoid haemorrhage?
  The pivotal multicentre randomized trial published in The New England Journal of Medicine (1993) enrolled 404 patients with aneurysmal SAH and demonstrated a statistically significant reduction in poor clinical outcome at 6 weeks for those receiving nimodipine versus placebo.

• How does Nimotop differ from other calcium‑channel blockers such as amlodipine?
  While both belong to the dihydropyridine class, nimodipine has a higher affinity for cerebral arterial smooth muscle and limited systemic vasodilatory effects, making it suitable for neurovascular protection. Amlodipine primarily reduces systemic arterial pressure and is used for hypertension and angina.

• Can Nimotop be safely used in patients who are pregnant or breastfeeding?
  Animal studies have shown adverse developmental effects at high doses, and there are insufficient controlled human data. Consequently, nimodipine should be prescribed during pregnancy or lactation only when the potential benefit outweighs the potential risk, and after careful risk assessment by the treating physician.

• Is there a known difference in nimodipine formulation between Europe and Asia?
  The European Union and Asian markets both use film‑coated 30 mg tablets, but inactive ingredients may vary slightly (e.g., different colourants or fillers). These differences do not affect the pharmacokinetic profile, but patients sensitive to a particular excipient should review the product label for region‑specific details.
