Generic Inderal La Information

Introduction

Inderal La is a long‑acting formulation of the non‑selective β‑adrenergic blocker propranolol. It belongs to the blood‑pressure medication group and is used primarily to lower elevated blood pressure, control abnormal heart rhythms, and reduce the workload of the heart. In Hong Kong, cardiovascular disease remains a leading cause of morbidity, with hypertension affecting roughly one‑third of adults over 45 years of age. A reliable β‑blocker such as Inderal La therefore plays a central role in the management of hypertension, angina, and several arrhythmic conditions. The product is manufactured by a global pharmaceutical company that licenses the proprietary “La” (long‑acting) delivery system, providing once‑daily dosing convenience for many patients.

What is Inderal La?

Inderal La is a brand‑name tablet that contains the active compound propranolol hydrochloride. The “La” suffix denotes a specially engineered matrix that releases the drug gradually over 24 hours, allowing a single daily dose. Propranolol was first synthesized in the early 196s and became one of the earliest β‑blockers marketed worldwide. While the original brand name is Inderal, many generic versions containing the same active ingredient are available across different regions. Our online pharmacy supplies this formulation as a cost‑effective alternative, adhering to the same pharmaco‑technical standards required by the Hong Kong Medicines (Traditional Chinese Medicine) Ordinance.

How Inderal La Works

Propranolol blocks β₁ and β₂ adrenergic receptors in the heart, vascular smooth muscle, and bronchial tree. By preventing catecholamines (epinephrine and norepinephrine) from binding to these receptors, the drug produces three core physiological effects:

• Negative chronotropy: a reduction in heart‑rate, lowering myocardial oxygen demand.
• Negative inotropy: a modest decrease in the force of cardiac contraction, which reduces systolic blood‑pressure spikes.
• Negative dromotropy: slower conduction through the atrioventricular node, useful for certain supraventricular arrhythmias.

The extended‑release matrix of Inderal La yields steady plasma concentrations that are typically achieved within 6–8 hours after ingestion and maintained for approximately 24 hours. The drug is metabolised hepatically (primarily by CYP2D6) and eliminated via the kidneys; a half‑life of 3–5 hours for immediate‑release propranolol is effectively lengthened to about 12 hours in the LA formulation, supporting once‑daily administration.

Conditions Treated with Inderal La

• Essential hypertension: Propranolol reduces systemic vascular resistance and cardiac output, lowering systolic and diastolic pressures. In Hong Kong, hypertension prevalence is estimated at 27 % among adults aged ≥ 35 years, making β‑blockers a core component of many treatment algorithms.
• Angina pectoris: By decreasing myocardial oxygen consumption, propranolol alleviates chest‑pain episodes caused by coronary artery disease.
• Atrial fibrillation and other supraventricular tachyarrhythmias: The drug’s AV‑node‑blocking properties help control ventricular rate.
• Migraine prophylaxis: Although not a blood‑pressure indication, propranolol is widely accepted for reducing migraine frequency, especially in patients with comorbid hypertension.
• Essential tremor: The central β‑adrenergic blockade diminishes tremor amplitude in many individuals.

Each indication is supported by randomized controlled trials and meta‑analyses that demonstrate modest but clinically meaningful reductions in blood‑pressure readings, arrhythmic episodes, or migraine days per month.

Who is Inderal La For?

Inderal La is appropriate for adults who require sustained β‑blockade without the inconvenience of multiple daily tablets. Typical candidates include:

• Patients with stage 1–2 hypertension who have not achieved target blood pressure on monotherapy with diuretics or calcium‑channel blockers.
• Individuals with chronic stable angina whose symptoms persist despite nitrates or lifestyle modification.
• Adults with paroxysmal atrial fibrillation who need rate control and have normal or mildly reduced left‑ventricular ejection fraction.
• Migraine sufferers who also have hypertension, providing dual therapeutic benefit.

Contra‑indications limit use in certain populations: patients with severe asthma or chronic obstructive pulmonary disease (COPD), uncontrolled heart‑failure (NYHA class III–IV), second‑ or third‑degree AV block without a pacemaker, and those with symptomatic bradycardia (< 50 bpm). Caution is also advised for individuals with diabetes mellitus who rely on adrenergic symptoms to recognize hypoglycaemia.

Risks, Side Effects, and Interactions

Common

• Fatigue or generalized weakness
• Dizziness, especially upon standing (orthostatic hypotension)
• Cold extremities (hands/feet) due to peripheral vasoconstriction
• Gastro‑intestinal upset (nausea, mild abdominal discomfort)

Rare

• Depression or mood changes
• Sleep disturbances, including vivid dreams or insomnia
• Skin rash or pruritus
• Impaired glucose tolerance (may unmask latent diabetes)

Serious

• Significant bradycardia (< 40 bpm) or high‑grade AV block
• Exacerbation of severe asthma or bronchospasm
• Acute heart‑failure decompensation
• Hypoglycaemic unawareness in insulin‑treated diabetics

Clinically Relevant Drug–Drug Interactions

• Calcium‑channel blockers (e.g., verapamil, diltiazem): additive AV‑node slowing → heightened risk of bradycardia.
• Other antihypertensives (ACE inhibitors, diuretics): synergistic blood‑pressure reduction may cause symptomatic hypotension.
• Antidiabetic agents (insulin, sulfonylureas): β‑blockade can mask tachycardia, a key hypoglycaemia warning sign.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs): may blunt antihypertensive effect.
• CYP2D6 inhibitors (e.g., fluoxetine, quinidine): increase propranolol plasma levels, raising toxicity risk.

Patients should disclose all prescribed, over‑the‑counter, and herbal products before initiating therapy.

Practical Use: Dosing, Missed Dose, Overdose

• Typical starting dose for hypertension: 80 mg of Inderal La taken once daily in the morning. Dose titration may proceed in 40–80 mg increments every 2–4 weeks to a maximum of 240 mg daily, depending on blood‑pressure response and tolerability.
• Angina or arrhythmia dosing: initial 80 mg daily, with possible increase to 320 mg daily (divided as 160 mg twice daily of immediate‑release equivalents, or equivalent LA dosing under specialist guidance).
• Missed dose: If a dose is forgotten, take it as soon as it is remembered provided that at least 8 hours have not elapsed since the scheduled time. Otherwise, skip the missed dose and resume the regular schedule; do not double‑dose.
• Overdose management: Symptoms may include severe bradycardia, hypotension, bronchospasm, and hypoglycaemia. Immediate medical attention is required; treatment may involve intravenous glucagon, atropine, or supportive cardiovascular monitoring.
• Food and alcohol: Inderal La can be taken with or without meals; however, high‑fat meals may slightly delay absorption. Alcohol may potentiate hypotensive effects and should be consumed cautiously.
• Renal or hepatic impairment: Dose reduction is advisable in moderate hepatic dysfunction (Child‑Pugh B) and severe renal impairment (eGFR < 30 mL/min).

FAQ

• Is Inderal La available in both brand‑name and generic forms in Hong Kong?
  Yes. The original brand is marketed as Inderal (or Inderal La for the long‑acting version), while numerous generic propranolol tablets meet the same regulatory standards. Generic options are typically less expensive and widely prescribed.

• Does Inderal La require special storage conditions?
  The tablets should be stored at room temperature, between 20 °C and 25 °C (68 °F–77 °F), protected from excess moisture, direct sunlight, and heat. No refrigeration is needed.

• What does the “La” designation signify on the packaging?
  “La” stands for “long‑acting,” indicating that the tablet contains a controlled‑release matrix designed to deliver propranolol steadily over a 24‑hour period.

• Can I travel internationally with Inderal La?
  Yes, provided you carry the medication in its original labelled container, have a copy of the prescription (if required by the destination country), and keep the quantity within personal‑use limits.

• Are there any dietary restrictions while taking Inderal La?
  No strict restrictions exist, but large amounts of caffeine or high‑sodium foods can counteract the blood‑pressure‑lowering effect. Maintaining a balanced diet supports optimal therapeutic outcomes.

• How does the formulation differ between regions such as the US, EU, and Asia?
  The active ingredient (propranolol hydrochloride) is identical worldwide. Differences may lie in inert excipients, tablet size, or coating agents to meet local regulatory specifications. Such variations do not alter the clinical efficacy.

• What are the most common reasons for discontinuing Inderal La?
  Patients often stop due to intolerable fatigue, pronounced dizziness, or emergent respiratory issues such as asthma exacerbation. Any decision to cease therapy should be discussed with a qualified clinician.

• Does propranolol cross the placenta, and is it safe during pregnancy?
  Propranolol does cross the placenta and is classified as pregnancy category C in many jurisdictions. It should only be used when the potential maternal benefit justifies possible fetal risk, and under strict medical supervision.

• Can Inderal La affect laboratory test results, such as drug screening?
  Routine drug screens generally do not detect propranolol. However, specialized pharmacokinetic assays may quantify β‑blocker levels if clinically indicated.

• Is there a difference in onset of action between immediate‑release and long‑acting propranolol?
  Immediate‑release tablets begin to lower heart rate and blood pressure within 30–60 minutes, while the long‑acting formulation achieves a steadier plasma concentration over several hours, minimizing peaks and troughs.

• What should I do if I experience sudden shortness of breath while on Inderal La?
  Shortness of breath may signal bronchospasm, especially in patients with underlying asthma or COPD. Seek immediate medical attention; the healthcare provider may need to discontinue β‑blockade and initiate bronchodilator therapy.

• Does Inderal La interact with over‑the‑counter herbal supplements?
  Certain herbs such as St. John’s wort induce CYP2D6 and could lower propranolol levels, reducing effectiveness. Conversely, high‑dose ginseng may increase blood pressure, counteracting the drug’s action.
