Generic Verampil Information

Introduction

Verampil is a calcium‑channel blocker that contains the active ingredient verapamil hydrochloride (Verapamil Hcl). It belongs to the blood‑pressure medication group and is used primarily to lower elevated arterial pressure, control abnormal heart rhythms, and relieve angina pectoris. In Hong Kong, verapamil‑based therapy is listed under the Hospital Authority’s formulary for hypertension and cardiac arrhythmias, making Verampil a relevant option for patients who need an evidence‑based, orally administered drug with a long history of clinical use.

What is Verampil?

Verampil is the generic version of the original brand‑name products Calan, Isoptin, and other verapamil hydrochloride tablets that have been marketed worldwide. It contains the same active compound, verapamil Hcl, in identical crystal form and strength. Our online pharmacy provides this generic alternative as a cost‑effective treatment option, sourced from licensed manufacturers that meet international Good Manufacturing Practice (GMP) standards.

How Verampil Works

Verapamil belongs to the phenylalkylamine class of calcium‑channel blockers. It selectively inhibits L‑type calcium channels in vascular smooth muscle and cardiac myocytes. By reducing calcium influx, the drug causes:

• Vasodilation of arterioles, which lowers systemic vascular resistance and consequently reduces systolic and diastolic blood pressure.
• Negative inotropic and chronotropic effects on the heart, slowing conduction through the atrioventricular (AV) node and decreasing heart rate. These actions help treat supraventricular tachycardia and protect the myocardium during angina.

The onset of antihypertensive effect occurs within 1–2 hours after oral dosing, with peak plasma concentrations reached at 1–3 hours. Verapamil is metabolised primarily by hepatic cytochrome P450 3A4 (CYP3A4) and eliminated via the urine and bile, giving a terminal half‑life of 3–7 hours for immediate‑release formulations and up to 12 hours for extended‑release tablets.

Conditions Treated with Verampil

• Hypertension – Essential (primary) hypertension is prevalent in Hong Kong, affecting an estimated 25 % of adults over 45 years. Verampil reduces peripheral resistance, contributing to longterm blood‑pressure control.
• Angina Pectoris – By decreasing myocardial oxygen demand and improving coronary blood flow, verapamil alleviates stable angina symptoms.
• Supraventricular Tachycardia (SVT) – The drug’s AV‑node blocking properties are useful for controlling atrial fibrillation, atrial flutter, and paroxysmal SVT.
• Migraine Prophylaxis (off‑label) – Some clinicians in Hong Kong prescribe verapamil for chronic migraine prevention, based on its vascular stabilising effect.

These indications are supported by regulatory approval from the US FDA, EMA, and the Hong Kong Department of Health, which recognises verapamil as an essential antihypertensive and anti‑arrhythmic agent.

Who is Verampil For?

Verampil is appropriate for adult patients who:

• Have been diagnosed with stage 1 or stage 2 hypertension and require pharmacologic control in addition to lifestyle modification.
• Experience stable angina that is not adequately managed by β‑blockers or nitrates alone.
• Require rate control for atrial fibrillation, atrial flutter, or other SVTs, especially when β‑blockers are contraindicated (e.g., severe chronic obstructive pulmonary disease).
• Are able to swallow tablets and have adequate hepatic function for metabolism.

Contraindications include:

• Known hypersensitivity to verapamil or any excipients.
• Second‑ or third‑degree AV block without a pacemaker.
• Severe hypotension (systolic < 90 mmHg).
• Sick‑sinus syndrome without pacing support.
• Congestive heart failure with reduced ejection fraction (LVEF < 35 %) when using immediate‑release formulations.

Clinicians should assess renal and hepatic function before initiating therapy, as dose adjustments may be needed in moderate impairment.

Risks, Side Effects, and Interactions

Common

• Headache – Often mild and transient during dose titration.
• Peripheral edema – Swelling of the ankles due to vasodilation; may improve with dose reduction or diuretic addition.
• Constipation – Result of reduced gastrointestinal smooth‑muscle contractility.
• Dizziness or light‑headedness – Related to blood‑pressure lowering, especially after the first dose.

Rare

• Bradycardia – Heart rate < 50 bpm, necessitating review of dose or addition of a pacemaker.
• Gingival hyperplasia – Overgrowth of gum tissue, reported infrequently.
• Photosensitivity – Skin rash after prolonged sun exposure.

Serious

• Severe hypotension – Systolic pressure < 80 mmHg can cause syncope or organ hypoperfusion; immediate medical attention required.
• Heart block – Progression to complete (third‑degree) AV block may occur, especially in patients with pre‑existing conduction disease.
• Liver injury – Rare elevation of transaminases or cholestatic hepatitis; monitor liver function tests in long‑term use.

Clinically Relevant Drug Interactions

• CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin, grapefruit juice) increase verapamil plasma levels, raising the risk of bradycardia and hypotension.
• CYP3A4 inducers (e.g., rifampicin, carbamazepine, St. John’s wort) reduce efficacy, potentially requiring dose escalation.
• β‑blockers – Combined use may cause excessive bradycardia or AV‑node suppression; careful monitoring is advised.
• Digoxin – Verapamil raises digoxin concentrations; dose adjustment may be necessary.
• Lithium – Concomitant therapy can increase lithium levels, risking toxicity.

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

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing for hypertension – Immediate‑release tablets: 80–120 mg taken three times daily. Extended‑release tablets: 240 mg once daily, titrated up to 480 mg based on response.
• Angina – 80–120 mg three times daily (immediate‑release) or 240 mg once daily (extended‑release).
• SVT rate control – 80 mg three times daily initially; may increase to 240 mg per day as tolerated.

Missed dose: If a dose is missed by less than 12 hours, take it as soon as remembered. If more than 12 hours have passed, skip the missed dose and resume the regular schedule. Do not double‑dose.

Overdose: Symptoms may include profound hypotension, severe bradycardia, cardiac arrest, or seizures. Immediate medical emergency care is required. Activated charcoal may be considered if ingestion occurred within one hour. Supportive measures such as intravenous fluids, atropine, or vasopressors are employed in hospital settings.

Precautions:

• Take tablets with a full glass of water; food does not significantly affect absorption, but a light meal may reduce gastrointestinal upset.
• Avoid excessive alcohol, which can enhance hypotensive effects.
• Patients with hepatic impairment should start at the lower end of the dosing range.
• Pregnant or lactating women must consult a physician; verapamil is classified as Category C (risk cannot be ruled out).

FAQ

• Is Verampil available in both brand‑name and generic forms in Hong Kong?
  Yes. The brand‑name products such as Calan and Isoptin are registered in Hong Kong, while Verampil is the approved generic version containing the same verapamil Hcl. Both meet the same regulatory standards for safety and efficacy.

• Does Verampil require any special storage conditions?
  Store the tablets at room temperature (15 °C–30 °C), protected from moisture, direct sunlight, and heat. Do not refrigerate or freeze, as extreme temperatures may degrade the active ingredient.

• What do the tablets look like and how are they packaged?
  Verampil tablets are typically round, film‑coated, and available in 80 mg, 120 mg, and 240 mg strengths. They are packaged in sealed blister packs or high‑density polyethylene bottles, each bearing a batch number and expiry date for traceability.

• Can Verampil be imported for personal use without a prescription in Hong Kong?
  Personal import of prescription‑only medicines is regulated by the Hong Kong Department of Health. While Verampil is classified as prescription‑only, our online pharmacy operates as a licensed broker, ensuring that all orders comply with local import rules and are accompanied by the necessary documentation.

• Are there any specific warnings for Asian populations?
  Pharmacogenomic data suggest that certain CYP3A4 polymorphisms, more prevalent in East Asian groups, may slightly reduce verapamil metabolism, leading to higher plasma concentrations. Clinicians often start at the lower end of the dosing range and monitor blood pressure and heart rate closely.

• Does the formulation differ between regions such as the US, EU, and Asia?
  The core active ingredient, verapamil Hcl, is identical worldwide. However, inactive excipients (e.g., fillers) may vary to meet regional pharmacopeial standards. These differences rarely affect therapeutic outcomes but can influence allergies to specific additives.

• What should I do if I need to travel with Verampil?
  Keep the medication in its original packaging with a copy of the prescription or a physician’s letter. Carry it in hand luggage to avoid temperature extremes in cargo holds, and ensure the supply covers the entire trip plus a few extra days in case of delays.

• Is it safe to take Verampil with over‑the‑counter antacids?
  Antacids containing aluminium or magnesium hydroxide do not significantly interfere with verapamil absorption. Nonetheless, avoid taking large doses of antacids within one hour of the Verampil dose to minimise any potential gastric pH‑related effects.

• How does Verampil compare with other calcium‑channel blockers like amlodipine?
  Verapamil has stronger negative inotropic and chronotropic effects, making it preferable for rate control in arrhythmias, whereas amlodipine primarily induces peripheral vasodilation with minimal cardiac conduction impact. Choice depends on the clinical target—blood‑pressure reduction alone versus combined anti‑arrhythmic therapy.

• What clinical trials established Verampil’s efficacy for hypertension?
  Large‑scale, double‑blind trials such as the INSIGHT and PRACTICAL studies demonstrated that verapamil achieved an average systolic reduction of 10–12 mmHg compared with placebo, with a comparable safety profile to other first‑line antihypertensives. These trials included diverse Asian cohorts, confirming its efficacy across ethnic groups.
