Generic Losartan Information

Introduction

Losartan (active compound: Losartan Potassium) belongs to the class of angiotensin II receptor blockers (ARBs) and is prescribed primarily for the management of hypertension. In the United Kingdom it is listed on the NHS formulary and is also approved for reduction of cardiovascular risk in patients with left‑ventricular hypertrophy, for diabetic nephropathy protection, and for the treatment of primary hyper‑aldosteronism after appropriate testing. The medication is manufactured by several reputable pharmaceutical companies; the most widely recognised brand name is Cozaar. Losartan is therefore frequently encountered both as a branded product and as a low‑cost generic alternative.

What is Losartan?

Losartan is the generic version of the original branded product Cozaar, containing the same active compound Losartan Potassium. It is classified as an angiotensin II type 1 (AT₁) receptor antagonist. The drug was first approved in the United States in 1995 and subsequently received UK marketing authorisation in 1997. Multiple manufacturers produce Losartan to the same monograph standards set by the Medicines and Healthcare products Regulatory Agency (MHRA).

Our online pharmacy provides this generic alternative as a cost‑effective treatment option, delivering the identical pharmacological profile of Cozaar while reducing the financial burden on patients.

How Losartan Works

Losartan blocks the binding of angiotensin II to AT₁ receptors located on vascular smooth muscle, adrenal cortex, and renal tubules. Angiotensin II is a potent vasoconstrictor that also stimulates aldosterone secretion, leading to sodium and water retention. By preventing this interaction, Losartan produces three clinically relevant effects:

1. Vasodilation – arterial smooth muscle relaxes, lowering systemic vascular resistance.
2. Reduced aldosterone secretion – decreases sodium reabsorption and promotes natriuresis, contributing to volume reduction.
3. Attenuation of myocardial remodelling – long‑term blockade mitigates hypertrophic signalling in the heart, lowering the risk of left‑ventricular hypertrophy.

Onset of blood‑pressure lowering is typically observed within 2 hours, with a peak effect around 4–6 hours. The drug’s elimination half‑life is approximately 2 hours for Losartan and 6–9 hours for its active metabolite (EXP‑3174), allowing once‑daily dosing for most adults. Clearance is primarily hepatic; renal excretion accounts for about 35 % of the metabolite.

Conditions Treated with Losartan

• Essential (primary) hypertension – reduces systolic and diastolic pressure, decreasing stroke and myocardial infarction risk. In the UK, hypertension affects ~13 % of adults, making effective antihypertensives a public‑health priority.
• Diabetic nephropathy – slows progression of micro‑albuminuria and preserves glomerular filtration rate in type 2 diabetes, as demonstrated in the RENAAL trial.
• Left‑ventricular hypertrophy – improves echocardiographic parameters and reduces cardiovascular events in patients with hypertension‑induced cardiac remodelling.
• Primary hyper‑aldosteronism (after confirmatory testing) – provides a medical alternative when surgery is unsuitable, controlling blood pressure and serum potassium.

All indications are supported by NICE technology appraisal guidance (TA560) and by peer‑reviewed clinical trials published in The Lancet and JAMA.

Suitable Candidates for Losartan Treatment

Losartan is appropriate for adult patients (≥ 18 years) who:

• Require antihypertensive therapy but have contraindications or intolerance to ACE inhibitors (e.g., cough, angio‑edema).
• Have type 2 diabetes with early signs of renal involvement.
• Exhibit left‑ventricular hypertrophy on echocardiography and need secondary cardiac protection.
• Are confirmed to have primary hyper‑aldosteronism and are not surgical candidates.

Conversely, Losartan should be avoided or used with caution in:

• Pregnant or breastfeeding women (category X – teratogenic risk).
• Patients with severe hepatic impairment (dose adjustment required).
• Individuals with a history of angio‑edema related to ARBs or ACE inhibitors.
• Those on concurrent potassium‑sparing diuretics or high‑dose potassium supplements, due to hyperkalaemia risk.

Risks, Side Effects, and Interactions

Common

• Dizziness or light‑headedness – usually related to postural hypotension, particularly after initiation or dose escalation.
• Headache – mild and transient in most cases.
• Fatigue – may occur as the body adjusts to lower blood pressure.
• Upper respiratory tract infection symptoms – not causally linked but reported in clinical trials.

Rare

• Dry cough – less frequent than with ACE inhibitors but can occur.
• Elevated serum creatinine – indicative of reduced renal perfusion; monitor in patients with pre‑existing renal disease.
• Hypokalaemia – when combined with thiazide or loop diuretics.

Serious

• Angio‑edema – swelling of face, lips, tongue, or airway; requires immediate medical attention.
• Severe hyperkalaemia – especially in patients with renal insufficiency or those taking potassium‑sparing agents; can precipitate cardiac arrhythmia.
• Acute renal failure – may develop in volume‑depleted patients or in those with bilateral renal artery stenosis.

Drug–Drug Interactions

• Non‑steroidal anti‑inflammatory drugs (NSAIDs) – may blunt antihypertensive effect and increase renal risk.
• Potassium‑sparing diuretics (e.g., spironolactone), potassium supplements, or salt substitutes – raise serum potassium; concomitant use warrants close monitoring.
• Lithium – Losartan can increase lithium levels, heightening the risk of toxicity.
• Dual‑renin‑angiotensin system blockade (e.g., ACE inhibitor + ARB) – not recommended due to excess risk of hypotension, hyperkalaemia, and renal impairment.

All patients should disclose over‑the‑counter medications and herbal products (e.g., St John’s wort) to their healthcare professional.

Practical Use: Dosing, Missed Dose, Overdose

• Initial adult dose – 50 mg taken orally once daily.
• Titration – may be increased to 100 mg once daily after 2 weeks if blood‑pressure targets are not met. In patients with severe hypertension, a loading dose of 100 mg may be considered under specialist guidance.
• Renal or hepatic impairment – start at 25 mg once daily; avoid exceeding 50 mg daily unless closely monitored.
• Elderly patients – initiate at 25–50 mg daily, observing for orthostatic symptoms.

Missed dose: If a dose is forgotten and the next scheduled dose is ≥ 12 hours away, take the missed tablet as soon as remembered. If the time for the next dose is near, skip the missed tablet and resume the regular schedule. Do not double‑dose.

Overdose: Symptoms may include profound hypotension, dizziness, and renal dysfunction. Immediate medical attention is required. Management is supportive: monitor blood pressure, administer intravenous fluids as needed, and consider activated charcoal if ingestion was recent. No specific antidote exists.

Food & Alcohol: Losartan may be taken with or without food; however, excessive alcohol can amplify hypotensive effects and should be limited.

Lifestyle considerations: Maintain a low‑salt diet, regular aerobic exercise, and weight control to optimise blood‑pressure outcomes.

FAQ

• Is Losartan available in both brand‑name and generic forms in the UK?
  Yes. The original brand name is Cozaar, produced by Merck Sharp & Dohme. Generic Losartan Potassium, which contains the identical active ingredient, is widely marketed by multiple manufacturers and is typically less expensive.

• Does Losartan require special storage conditions?
  Losartan tablets should be stored at controlled room temperature (15–30 °C), protected from moisture and direct sunlight. They do not require refrigeration.

• What does a Losartan tablet look like?
  Generic tablets are usually white, round or oval, and may be film‑coated. The imprint varies by manufacturer; common markings include “L‑50” for a 50 mg strength.

• Can Losartan be safely imported for personal use in the UK?
  Personal importation of a three‑month supply of a prescription‑only medicine is permitted under UK customs rules provided the medication is for personal use, the importer holds a valid prescription, and the product complies with MHRA standards.

• Are there any ethnic‑specific dosage recommendations for Losartan?
  Clinical data indicate that Asian patients may experience a greater blood‑pressure response at standard doses; however, the NHS does not prescribe ethnic‑specific dosing. Clinicians may individually adjust dosage based on therapeutic response and tolerability.

• How does Losartan compare with ACE inhibitors in terms of cough?
  Cough is a class effect of ACE inhibitors due to accumulation of bradykinin. Losartan, as an ARB, has a markedly lower incidence of cough, making it a preferred alternative for patients who develop this side effect.

• What is the role of Losartan’s active metabolite, EXP‑3174?
  EXP‑3174 is approximately ten times more potent at AT₁ receptors than the parent compound and contributes significantly to the antihypertensive effect, especially during the later part of the dosing interval.

• Is there any impact of Losartan on laboratory drug testing?
  Losartan does not typically appear on standard employment drug screens. However, specific pharmacokinetic testing can detect the drug if required for clinical monitoring.

• Can Losartan be taken together with a low‑dose aspirin?
  Yes. Low‑dose aspirin (≤ 100 mg daily) does not interfere with Losartan’s antihypertensive action and is often recommended for cardiovascular protection in hypertensive patients.

• What should a patient do if they experience sudden swelling of the lips or tongue while on Losartan?
  Swelling may indicate angio‑edema, a serious adverse reaction. The patient should seek emergency medical care immediately; the medication must be stopped and alternative therapy considered.

Glossary

Angiotensin II receptor blocker (ARB)

A class of drugs that inhibit the vasoconstrictive and aldosterone‑secreting effects of angiotensin II by blocking AT₁ receptors, leading to blood‑pressure reduction.

Hyperkalaemia

An abnormally high concentration of potassium in the blood, which can cause muscle weakness, cardiac arrhythmias, and, in severe cases, cardiac arrest.

Left‑ventricular hypertrophy (LVH)

Thickening of the muscular wall of the heart’s left ventricle, often resulting from chronic high blood pressure and associated with increased cardiovascular risk.

Active metabolite (EXP‑3174)

A chemically transformed version of a parent drug that retains pharmacological activity; for Losartan, EXP‑3174 is more potent and contributes to the overall therapeutic effect.
