Generic Inderal Information

Introduction

Inderal (generic name propranolol) belongs to the beta‑adrenergic blocking agents, a class of medicines that reduce the activity of the sympathetic nervous system. In Hong Kong, Inderal is prescribed primarily for hypertension, angina pectoris, cardiac arrhythmias, and the prevention of migraine attacks. It is also used off‑label for essential tremor, anxiety‑related tachycardia, and certain hyperthyroid symptoms. The drug is marketed by AstraZeneca and other manufacturers worldwide. Because propranolol is inexpensive and widely studied, it remains a cornerstone of cardiovascular therapy in the local health system.

What is Inderal?

Inderal is a brand‑name formulation of propranolol, a non‑selective beta‑blocker that blocks both β₁ and β₂ adrenergic receptors. The original brand was launched in the 196s and remains on the market in many countries. Generic versions contain the identical active ingredient and are approved by the Hong Kong Department of Health.

Inderal is the generic version of the well‑known brand Propranolol, containing the same active compound propranolol. Our online pharmacy provides this generic alternative as a cost‑effective treatment option.

Common commercial strengths include 10 mg, 20 mg, 40 mg, and 80 mg tablets, as well as extended‑release (Inderal LA) and oral solution forms. Inactive ingredients vary by manufacturer but typically include lactose, microcrystalline cellulose, and magnesium stearate.

How Inderal Works

Propranolol binds competitively to β₁ receptors in the heart and β₂ receptors in the lungs, blood vessels, and skeletal muscle. By preventing catecholamines (epinephrine and norepinephrine) from activating these receptors, the drug produces several physiologic effects:

• Reduced heart rate (negative chronotropy) – slowing the sinus node reduces myocardial oxygen demand.
• Decreased contractility (negative inotropy) – lower stroke volume further eases cardiac workload.
• Diminished renin release – β₁ blockade in the juxtaglomerular cells reduces the renin‑angiotensin‑aldosterone cascade, contributing to blood‑pressure lowering.
• Stabilisation of vascular tone – β₂ blockade attenuates peripheral vasodilation that can trigger reflex tachycardia.

Onset of action occurs within 30–60 minutes after oral dosing, with a plasma half‑life of 3–6 hours for immediate‑release tablets. Extended‑release formulations maintain therapeutic concentrations for 12–24 hours, allowing once‑daily dosing in many patients.

Conditions Treated with Inderal

• Hypertension – Reduces systolic and diastolic pressure by lowering cardiac output and inhibiting renin secretion.
• Angina pectoris – Decreases myocardial oxygen consumption, preventing ischemic episodes during exertion.
• Supraventricular and ventricular arrhythmias – Controls heart‑rate‐related arrhythmias such as atrial fibrillation, atrial flutter, and ventricular premature beats.
• Migraine prophylaxis – Modulates central pain pathways and vascular tone, reducing the frequency of migraine attacks.
• Essential tremor – Dampens peripheral β‑adrenergic stimulation that contributes to tremor amplitude.
• Anxiety‑related tachycardia / performance anxiety – Limits the peripheral manifestations of sympathetic arousal.

In Hong Kong, hypertension affects approximately 30 % of adults over 40 years, and cardiovascular disease remains the leading cause of death. Beta‑blockers like propranolol are incorporated into local clinical guidelines (e.g., Hong Kong Cardiology Society recommendations) as first‑line agents for many of these indications.

Who is Inderal For?

• Adults with diagnosed hypertension who require additional blood‑pressure control beyond lifestyle measures or ACE‑inhibitors.
• Patients with stable angina who need heart‑rate reduction to alleviate chest pain during exertion.
• Individuals experiencing recurrent migraines (≥ 4 attacks per month) for whom preventive therapy is indicated.
• Those with essential tremor that interferes with daily activities, provided they have no contraindications to β‑blockade.
• Patients undergoing treatment for hyperthyroidism who need symptomatic control of tachycardia and tremor.

Contraindications include severe bradycardia (heart rate < 50 bpm), second‑ or third‑degree AV block without a pacemaker, uncompensated heart failure, active bronchospasm (asthma, COPD), and severe peripheral vascular disease. Caution is advised in patients with diabetes (masking of hypoglycaemic symptoms) and in the elderly, who may experience exaggerated hypotensive responses.

Risks, Side Effects, and Interactions

Common

• Fatigue, dizziness, or light‑headedness, especially after the first few doses.
• Cold extremities or mild peripheral vasoconstriction.
• Gastrointestinal discomfort (nausea, abdominal cramping).
• Sleep disturbances (insomnia or vivid dreams).

Rare

• Depression or mood changes.
• Erectile dysfunction or decreased libido.
• Bradycardia with heart rate < 45 bpm.
• Worsening of peripheral arterial disease symptoms (claudication).

Serious

• Severe hypotension (systolic < 90 mmHg) leading to syncope or organ hypoperfusion.
• Bronchospasm or acute asthma exacerbation in patients with underlying reactive airway disease.
• Heart block (second‑ or third‑degree) requiring pacemaker insertion.
• Congestive heart failure decompensation in patients with reduced ejection fraction.

Clinically Relevant Interactions

• Calcium channel blockers (e.g., verapamil, diltiazem) – additive negative‑chronotropic effect, may precipitate bradycardia.
• Antidiabetic agents (insulin, sulfonylureas) – propranolol can mask hypoglycaemic symptoms, necessitating closer glucose monitoring.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs) – may attenuate antihypertensive efficacy.
• CYP2D6 inhibitors (e.g., fluoxetine, paroxetine) – increase propranolol plasma concentrations, raising the risk of adverse events.
• Clonidine – abrupt discontinuation of clonidine while on propranolol can cause rebound hypertension.

Practical Use: Dosing, Missed Dose, Overdose

• Initial dosing for hypertension: 40 mg twice daily (immediate‑release) or 80 mg once daily (extended‑release). Titration is guided by blood‑pressure response, usually in increments of 20 mg every 1–2 weeks.
• Migraine prophylaxis: 80 mg at bedtime, titrated up to 240 mg per day as tolerated.
• Essential tremor: 40 mg three times daily, with possible increase to 120 mg per day.

Missed dose: Take the missed tablet as soon as remembered if at least 6 hours remain before the next scheduled dose. Otherwise, skip the missed dose and resume the regular dosing schedule; do not double‑dose.

Overdose: Symptoms may include severe bradycardia, hypotension, bronchospasm, and hypoglycaemia. Immediate medical attention is essential. Activated charcoal may be considered if ingestion occurred within one hour. Supportive care—intravenous fluids, atropine for bradycardia, and glucagon for refractory hypotension—are standard emergency measures.

Practical precautions

• Take tablets with food or a light snack to minimise gastrointestinal upset.
• Avoid abrupt discontinuation; taper the dose over 1–2 weeks to prevent rebound tachycardia or hypertension.
• Alcohol can potentiate hypotensive effects; limit intake.
• Patients with hepatic impairment may require dose reduction because propranolol is extensively metabolised by the liver.

FAQ

• Is Inderal available in both brand‑name and generic forms in Hong Kong?
  Yes. The original brand‑name product is marketed as Inderal, while generic propranolol tablets containing the same active ingredient are widely distributed. Generic versions are typically less expensive and are approved by the Hong Kong Department of Health.

• What should I do with Inderal if I travel to a hot climate?
  Store the tablets at a controlled room temperature (15‑30 °C). Prolonged exposure to high heat or humidity can degrade the active ingredient, so keep the medication in a sealed container away from direct sunlight.

• Does Inderal require refrigeration?
  No. Propranolol tablets are stable at ordinary room temperature. Refrigeration is unnecessary and may cause condensation that affects tablet integrity.

• How does the tablet appearance differ between manufacturers?
  Immediate‑release tablets are usually round or oval, scored for easy splitting, and may be white, pink, or orange depending on the brand. Extended‑release tablets are often oval and may have a distinct imprint such as “PR‑80”. Check the packaging label for specific identifiers.

• Can Inderal be imported for personal use without a prescription in Hong Kong?
  Hong Kong customs permits the import of a 30‑day supply of prescription medications for personal use without a prescription, provided the quantity is clearly for self‑treatment and the product is for personal consumption only.

• Are there any special warnings for Asian populations taking Inderal?
  Studies indicate that Asian patients may experience slightly higher plasma concentrations of propranolol due to genetic variations in CYP2D6 metabolism. Clinicians often start at lower doses and titrate more cautiously.

• Does propranolol affect drug testing for athletes?
  Propranolol is not a prohibited substance in most sports, but it can be listed as a "beta‑blocker" in certain auto‑racing or shooting disciplines where tremor suppression is regulated. Athletes should consult their sport’s governing body.

• What is the difference between immediate‑release and extended‑release formulations?
  Immediate‑release tablets deliver the full dose quickly, requiring multiple daily administrations. Extended‑release (Inderal LA) releases propranolol gradually, allowing once‑daily dosing and more stable plasma levels.

• Can I take Inderal with a low‑sodium diet?
  Yes. A low‑sodium diet complements the antihypertensive effect of propranolol and does not interfere with its pharmacokinetics. However, abrupt dietary changes should be discussed with a healthcare professional.

• Is there any interaction between Inderal and herbal supplements such as St. John’s wort?
  St. John’s wort induces CYP3A4 and may modestly reduce propranolol levels, potentially diminishing its efficacy. Patients using such supplements should inform their physician.

• How long can I safely stay on Inderal therapy?
  Propranolol can be used long‑term when monitored regularly. Periodic assessment of heart rate, blood pressure, and signs of bronchospasm is recommended, especially in elderly patients.

• What should I do if I experience sudden dizziness after taking Inderal?
  Dizziness may indicate orthostatic hypotension. Rise slowly from seated or lying positions, stay hydrated, and avoid alcohol. If dizziness persists or is accompanied by fainting, seek medical attention promptly.
