Generic Verapamil Information

Introduction

Verapamil is a calcium‑channel‑blocking agent used primarily to lower blood pressure and control heart rhythm. In the United Kingdom it is prescribed for hypertension, angina, and certain cardiac arrhythmias. The medication contains the active compound Arpamyl (verapamil hydrochloride) and belongs to the Blood Pressure therapeutic group. In addition to its core cardiovascular indications, verapamil is sometimes employed off‑label for migraine prophylaxis and cluster‑headache treatment, reflecting its broad vascular effects.

What is Verapamil?

Verapamil is a synthetic phenylalkylamine calcium‑channel blocker. It was first synthesised in the 197s and has been marketed worldwide under several brand names, including Arpamyl, Isoptin, and Verelan. The generic form contains the same active compound, verapamil hydrochloride, identified here as Arpamyl. The drug is manufactured by multiple reputable pharmaceutical firms, each required to meet the United Kingdom’s Medicines and Healthcare products Regulatory Agency (MHRA) standards for quality and safety.

How Verapamil Works

Verapamil inhibits the influx of calcium ions through L‑type voltage‑gated calcium channels in cardiac and smooth‑muscle cells. By reducing intracellular calcium, the drug produces three key effects:

• Vasodilation: Relaxation of arterial smooth muscle lowers systemic vascular resistance, reducing blood pressure.
• Negative inotropy and chronotropy: Diminished calcium entry into cardiac myocytes decreases contractile force and slows conduction through the atrioventricular (AV) node, useful for rate control in supraventricular tachycardia.
• Coronary artery dilation: Improves myocardial oxygen delivery, relieving anginal pain.

The onset of action after oral dosing occurs within 30–60 minutes, with peak plasma concentrations at 1.5–2 hours. Verapamil’s elimination half‑life ranges from 3 to 7 hours, prolonging to 8–12 hours with sustained‑release formulations. Renal and hepatic clearance both contribute, making dose adjustments necessary in severe renal or hepatic impairment.

Conditions Treated with Verapamil

• Essential Hypertension: Verapamil lowers systolic and diastolic pressures, particularly effective in patients whose blood pressure is driven by increased peripheral resistance.
• Chronic Stable Angina: By reducing myocardial oxygen demand and enhancing coronary blood flow, it alleviates exertional chest pain.
• Supraventricular Tachycardia (SVT) and Atrial Fibrillation with Rapid Ventricular Response: AV‑node blockade controls ventricular rate without affecting sinus node function.
• Cluster Headaches (off‑label): High‑dose verapamil has demonstrated efficacy in reducing attack frequency.
• Migraine Prophylaxis (off‑label): Calcium‑channel blockade can decrease cortical excitability, benefiting some migraineurs.

In the UK, hypertension affects approximately 30 % of adults, while coronary artery disease remains a leading cause of morbidity. Verapamil’s dual antihypertensive and anti‑anginal properties make it a valuable option within the National Health Service (NHS) formulary for patients unsuitable for beta‑blockers or ACE inhibitors.

Suitable Candidates for Verapamil Treatment

• Adults with uncomplicated essential hypertension who have contraindications to first‑line agents (e.g., asthma limiting beta‑blocker use).
• Patients with chronic stable angina where nitrate tolerance is problematic or where combined nitrate‑verapamil therapy is desired.
• Individuals with paroxysmal supraventricular tachycardia or atrial fibrillation where rate control is required and digoxin is unsuitable.
• Those requiring a non‑beta‑blocking rate‑control option due to chronic obstructive pulmonary disease (COPD) or peripheral vascular disease.

Verapamil is not appropriate for patients with severe left‑ventricular dysfunction (ejection fraction < 35 %), second‑ or third‑degree AV block without a pacemaker, or uncontrolled heart failure, as its negative inotropic effects can exacerbate these conditions. Caution is also advised in severe hepatic impairment and in patients taking concomitant strong CYP3A4 inhibitors (e.g., ketoconazole) due to increased plasma concentrations.

Risks, Side Effects, and Interactions

Common

• Headache – often mild and transient.
• Peripheral edema – particularly in the ankles; may be mitigated by dose adjustment.
• Constipation – related to reduced gastrointestinal smooth‑muscle activity.
• Dizziness or light‑headedness – especially after the first dose or dose escalation.

Rare

• Bradycardia – heart rate < 50 bpm, usually in patients with pre‑existing conduction disease.
• Hypotension – marked systolic fall (< 90 mmHg) leading to syncope.
• Gingival hyperplasia – over‑growth of gum tissue with prolonged use.

Serious

• Heart block – second‑ or third‑degree AV block requiring temporary or permanent pacing.
• Severe heart failure – worsening of symptoms such as dyspnoea, oedema, and reduced exercise tolerance.
• Liver enzyme elevation – hepatotoxicity manifesting as jaundice or abnormal LFTs.

Drug–Drug Interactions

• CYP3A4 inhibitors (e.g., itraconazole, clarithromycin) increase verapamil levels → heightened risk of bradycardia and hypotension.
• CYP3A4 inducers (e.g., rifampicin, carbamazepine) reduce efficacy → possible loss of blood‑pressure control.
• Beta‑blockers – additive negative‑chronotropic effect may cause profound bradycardia.
• Digoxin – verapamil raises digoxin concentrations; monitor serum levels closely.
• Statins metabolised by CYP3A4 (e.g., simvastatin, atorvastatin) – increased risk of myopathy; dose reduction may be required.

Patients should inform healthcare providers of all current medications, including over‑the‑counter supplements and herbal products such as St John’s wort.

Practical Use: Dosing, Missed Dose, Overdose

• Standard oral dose for hypertension: 80 mg to 240 mg daily, divided into two or three doses.
• Extended‑release tablets: 120 mg to 360 mg once daily; may be increased gradually based on response.
• Angina: 80 mg to 120 mg three times daily (immediate‑release) or 240 mg to 360 mg once daily (extended‑release).
• SVT rate control: 80 mg to 120 mg three times daily; loading dose is generally avoided.

Missed dose: Take the missed tablet as soon as it is remembered unless it is close to the time of the next scheduled dose. Do not double‑dose to compensate, as this may provoke hypotension or bradycardia.

Overdose: Symptoms may include severe hypotension, bradycardia, heart block, and respiratory depression. Immediate medical attention is required. Gastric lavage and activated are recommended if presentation occurs within one hour. Intravenous calcium gluconate, glucagon, or atropine may be administered by clinicians to counteract cardiovascular toxicity.

Precautions:

• Avoid large meals high in fat immediately before dosing, as they can delay absorption.
• Alcohol may potentiate hypotensive effects; limit consumption.
• Patients with renal or hepatic dysfunction should start at the lower end of the dosing range and be monitored closely.

FAQ

• Is Verapamil available in both immediate‑release and extended‑release formulations?
  Yes, the medication is marketed in tablets that release the active compound rapidly (usually three times daily) and in a sustained‑release form taken once daily. The choice depends on the clinical indication and patient tolerability.

• Can Verapamil be stored in a bathroom cabinet?
  Verapamil should be kept at room temperature, away from excessive heat, moisture, and direct sunlight. A bathroom cabinet is discouraged because humidity can degrade the tablet coating over time.

• What does the imprint on a generic Verapamil tablet look like?
  Imprints vary by manufacturer, but common markings include “VR‑80” or “VR‑240” indicating the dose strength. The colour is typically white or pale yellow, with a film coating that may be smooth or slightly textured.

• Does Verapamil interact with common herbal supplements?
  Herbal products such as St John’s wort (a CYP3A4 inducer) can reduce verapamil plasma levels, potentially diminishing its therapeutic effect. Patients should discuss any supplement use with their prescriber.

• Are there specific warnings for elderly patients taking Verapamil?
  Older adults are more susceptible to orthostatic hypotension and bradycardia. Starting at a low dose and titrating slowly is recommended, as is monitoring for dizziness or falls.

• Can Verapamil be taken while travelling across time zones?
  For immediate‑release tablets, maintain the original dosing interval (e.g., every 8 hours) as closely as possible, adjusting for the new local time. Extended‑release tablets should be taken at the same clock time each day to maintain steady plasma levels.

• How does Verapamil differ from other calcium‑channel blockers like amlodipine?
  Verapamil predominantly affects cardiac conduction and contractility, making it useful for rate control in arrhythmias, whereas amlodipine mainly induces peripheral vasodilation with minimal cardiac effects. The side‑effect profiles also differ, with verapamil more likely to cause constipation and bradycardia.

• Is Verapamil subject to UK import restrictions for personal use?
  Personal import of prescription medicines into the UK is allowed when the quantity does not exceed a three‑month supply and a valid prescription is held. Our online pharmacy assists customers in complying with these regulations.

• What are the differences between Verapamil tablets produced for the EU versus the US market?
  EU‑approved tablets must meet the European Pharmacopoeia specifications, which often include stricter limits on impurity levels. US tablets follow the United States Pharmacopeia (USP) standards. Formulation excipients may also differ, potentially affecting tolerability.

• Does Verapamil affect drug testing for employment or sport?
  Verapamil is not a prohibited substance in standard workplace or anti‑doping drug screens. However, it may appear in comprehensive blood chemistry panels, so informing the testing authority of legitimate medication use is advisable.

• Can Verapamil be safely combined with antihypertensive diuretics?
  Yes, combination therapy is common. Diuretics can counteract peripheral edema caused by verapamil, while verapamil provides additional blood‑pressure lowering. Dose adjustments and close monitoring are recommended to avoid excessive hypotension.
