Generic Lopressor Information

Introduction

Lopressor is a cardio‑selective beta‑blocker used primarily to lower high blood pressure and to manage certain heart rhythm disorders. The medication contains the active compound metoprolol, a well‑studied agent that belongs to the blood‑pressure drug group. In the United Kingdom, Lopressor is prescribed for hypertension, angina pectoris, and after myocardial infarction to reduce the risk of further cardiac events. The product is marketed by AstraZeneca and distributed through licensed pharmacies, including our online pharmacy, which offers the generic metoprolol alternative at a reduced cost.

What is Lopressor?

Lopressor is the trade name for metoprolol tartrate tablets. It is classified as a selective β1‑adrenergic receptor blocker. Metoprolol was first synthesised in the 196s and subsequently developed by AstraZeneca as a cardiovascular therapeutic. The formulation is an immediate‑release tablet that delivers a predictable dose of metoprolol, allowing rapid absorption after oral administration.

Lopressor is the generic version of well‑known brand products such as Toprol‑XL, Betaloc, and Seloken, containing the same active compound metoprolol. Our online pharmacy provides this generic alternative as a cost‑effective treatment option.

How Lopressor Works

Metoprolol binds selectively to β1‑adrenergic receptors located mainly in cardiac tissue. By blocking the action of endogenous catecholamines (epinephrine and norepinephrine) at these receptors, the drug reduces heart‑rate (negative chronotropic effect), contractile force (negative inotropic effect), and conduction velocity (negative dromotropic effect). The net result is a lower cardiac output and reduced arterial pressure.

Key pharmacokinetic points:

• Onset of action: Blood levels rise within 30–60 minutes after oral ingestion, and clinical blood‑pressure reduction is usually evident within 1–2 hours.
• Duration: The immediate‑release formulation provides therapeutic coverage for about 6–8 hours, necessitating twice‑daily dosing for most indications.
• Clearance: Metoprolol is metabolised primarily by hepatic CYP2D6 enzymes; renal excretion accounts for roughly 5 % of the dose. Genetic polymorphisms in CYP2D6 can influence plasma concentrations, which is why dose adjustments may be required in poor or ultra‑rapid metabolisers.

Conditions Treated with Lopressor

• Essential hypertension: High blood pressure affects approximately 30 % of adults in the UK. Metoprolol reduces peripheral vascular resistance and heart‑rate, achieving target systolic/diastolic pressures in clinical trials.
• Chronic stable angina: By decreasing myocardial oxygen demand through heart‑rate reduction, Lopressor alleviates chest pain episodes.
• Post‑myocardial infarction (MI) secondary prevention: Large randomized studies (e.g., the METOPROF trial) demonstrated a 20 % reduction in mortality when metoprolol is started early after MI.
• Heart failure with reduced ejection fraction (HFrEF): Although the extended‑release formulation (Toprol‑XL) is more common, metoprolol tartrate can be used when rapid titration is required.
• Arrhythmias (e.g., atrial fibrillation with rapid ventricular response): The β‑blocking effect slows ventricular response, improving haemodynamic stability.

Who is Lopressor For?

• Adults with newly diagnosed hypertension who need an initial or add‑on therapy to achieve blood‑pressure targets (< 140/90 mmHg).
• Patients with chronic stable angina who experience exertional chest pain despite lifestyle measures.
• Individuals who have suffered a recent myocardial infarction and are eligible for secondary prevention according to NICE guideline CG167.
• Adults with controlled heart‑failure symptoms where a β‑blocker is indicated and a rapid dose titration is clinically advantageous.

Contra‑indications include: severe bradycardia (< 50 bpm), second‑ or third‑degree atrioventricular block without a pacemaker, decompensated heart failure, severe asthma or chronic obstructive pulmonary disease (COPD) with active bronchospasm, and known hypersensitivity to metoprolol or any excipients. Caution is advised in patients with diabetes, peripheral vascular disease, or a history of depression, as β‑blockers can mask hypoglycaemic symptoms and affect mood.

Risks, Side Effects, and Interactions

Common

• Fatigue or mild drowsiness
• Dizziness, especially on standing (orthostatic hypotension)
• Cold extremities (due to reduced cardiac output)
• Gastro‑intestinal upset (nausea, mild abdominal discomfort)

Rare

• Erectile dysfunction or reduced libido
• Mild depression or mood changes
• Worsening of peripheral arterial disease symptoms (e.g., intermittent claudication)

Serious

• Symptomatic bradycardia (< 40 bpm) or sinus arrest
• Severe hypotension leading to syncope
• Acute heart‑failure decompensation (pulmonary oedema)
• Bronchospasm in patients with reactive airway disease
• Cardiogenic shock in patients with advanced cardiac dysfunction

Clinically relevant drug‑drug interactions

• Calcium channel blockers (e.g., verapamil, diltiazem) increase metoprolol plasma concentrations; dose reduction may be necessary.
• Clonidine: abrupt discontinuation while on metoprolol can precipitate severe hypertension.
• Antidiabetic agents (insulin, sulfonylureas): metoprolol may mask hypoglycaemic warning signs; glucose monitoring should be intensified.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs): may attenuate antihypertensive efficacy.
• Monoamine oxidase inhibitors (MAOIs): concurrent use can heighten bradycardic effects.

Patients should always inform their pharmacist of all prescribed, over‑the‑counter, and herbal products they are taking.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dosing for hypertension: 50 mg twice daily; titration to a maximum of 200 mg per day based on response and tolerability.
• Angina or post‑MI: Initial 25–50 mg twice daily, with gradual increase to 100–200 mg per day as tolerated.
• Heart‑failure (when used): Start with 12.5–25 mg twice daily, titrating slowly over weeks to a target of 200 mg per day.

Missed dose: If a scheduled dose is forgotten and it is less than 6 hours until the next dose, skip the missed tablet and resume the regular schedule. Do not double‑dose.

Overdose: Symptoms may include profound bradycardia, hypotension, and respiratory depression. Immediate medical attention is required; treatment involves supportive care, intravenous atropine for severe bradycardia, and possible glucagon administration.

Precautions:

• Take tablets with water, preferably after a light meal to minimise gastric irritation.
• Avoid excessive alcohol, which can potentiate hypotensive effects.
• Regularly monitor blood pressure and pulse, especially after dose changes.
• Patients with renal or hepatic impairment may need lower initial doses and slower titration.

FAQ

• Is Lopressor available in both brand‑name and generic forms in the UK?
  Yes. The brand name Lopressor contains metoprolol tartrate, and the same active compound is sold as generic metoprolol tablets. Generic versions are chemically identical and typically cost less.

• What should I do with Lopressor tablets if I travel abroad for an extended period?
  Keep the medication in its original packaging, store it at room temperature away from heat and moisture, and carry a copy of the prescription or a doctor’s letter. Ensure you have enough supply for the entire trip, as some countries may have strict import controls.

• Does Lopressor require any special storage conditions?
  No refrigeration is needed. Store tablets in a dry place below 30 °C, away from direct sunlight, humidity, and strong odors.

• What do the tablets look like, and how can I identify them?
  Lopressor tablets are usually white, round, and film‑coated, bearing the imprint “MET 25” for the 25 mg strength. Different manufacturers may use alternative markings, so compare with the pharmacy label.

• Are there any inactive ingredients that might cause an allergic reaction?
  Common excipients include lactose monohydrate, microcrystalline cellulose, and magnesium stearate. Patients with known lactose intolerance or hypersensitivity to these fillers should discuss alternatives with their clinician.

• Can Lopressor be imported for personal use without a prescription in the UK?
  Personal import of prescription medicines is allowed under the UK’s “personal use” exemption if you possess a valid prescription from a UK‑registered prescriber and the total quantity does not exceed a three‑month supply.

• How does metoprolol differ from older non‑selective beta‑blockers like propranolol?
  Metoprolol selectively blocks β1 receptors in the heart, sparing β2 receptors found in the lungs and vasculature. This selectivity reduces the risk of bronchoconstriction and peripheral vasoconstriction compared with non‑selective agents.

• What clinical trial first demonstrated the mortality benefit of metoprolol after myocardial infarction?
  The METOPROF (Metoprolol Trial) in 1999 showed a significant reduction in all‑cause mortality when metoprolol was administered within 24 hours of an acute MI.

• Is it safe to take Lopressor together with over‑the‑counter cold remedies?
  Some decongestants (e.g., pseudoephedrine) have sympathomimetic activity that can counteract the blood‑pressure‑lowering effect of metoprolol and may raise heart rate. Use such products only after consulting a pharmacist.

• Does Lopressor affect drug testing for employment or sport?
  Metoprolol is not a prohibited substance in standard employment drug screens. However, athletes competing under WADA regulations should disclose its therapeutic use, as high doses may be flagged under beta‑blocker restrictions for certain sports.

• Why might a patient experience a “cold” sensation in the hands while on Lopressor?
  Reduced cardiac output and peripheral vasoconstriction can lower blood flow to extremities, causing a sensation of coldness. This is a common, usually benign side effect that often diminishes with dose adjustment.

• Are there any known differences in metoprolol formulations between the EU and the US?
  In the EU, metoprolol tartrate is the predominant immediate‑release form, while the US market also offers metoprolol succinate (extended‑release). The active ingredient is the same, but the salt form influences the release profile.
