Drug Class: Angiotensin II Receptor Blocker (ARB) | Form: Oral Tablet | Prescription Status: Prescription Only (Rx) — DRAP Registered
What is Eziday 50mg Tablet?
Eziday 50mg contains Losartan Potassium — one of the most widely prescribed and clinically proven angiotensin receptor blockers (ARBs) in cardiovascular medicine. It works by selectively blocking the angiotensin II type 1 (AT1) receptor — preventing the body's most powerful blood vessel-narrowing hormone from raising blood pressure, retaining sodium and water, and damaging blood vessel walls. Unlike ACE inhibitors that block the production of angiotensin II, Losartan blocks the receptor it acts on — producing equivalent blood pressure lowering with a significantly lower risk of the persistent dry cough that affects many patients on ACE inhibitors. Eziday 50mg is prescribed for high blood pressure (ہائی بلڈ پریشر), stroke prevention in patients with left ventricular hypertrophy, and kidney protection in Type 2 diabetic patients — offering cardiovascular and renal protection beyond simple blood pressure control.
What is Eziday 50mg Used For?
- Essential hypertension — first and second-line treatment of high blood pressure in adults and elderly patients (ہائی بلڈ پریشر)
- Stroke prevention — reducing the risk of stroke in hypertensive patients with left ventricular hypertrophy (LVH) — an established and unique indication of Losartan supported by the landmark LIFE trial (فالج کی روک تھام)
- Diabetic nephropathy — slowing the progression of kidney disease and reducing protein leakage into urine in hypertensive patients with Type 2 Diabetes (ذیابیطس میں گردوں کی حفاظت)
- Cardiovascular risk reduction — reducing long-term risk of heart attack, stroke, and heart failure in high-risk hypertensive patients
- Heart failure — used in patients who cannot tolerate ACE inhibitors to reduce cardiovascular mortality and hospitalisation
How Does Eziday 50mg Work?
Angiotensin II Receptor Blockade: The renin-angiotensin-aldosterone system (RAAS) is the body's primary hormonal blood pressure regulator. When blood pressure falls or sodium levels drop, the kidneys release renin — triggering a cascade that produces angiotensin II. Angiotensin II is an extremely potent vasoconstrictor — it narrows blood vessels, promotes aldosterone release causing sodium and water retention, stimulates the heart to work harder, and causes long-term damage to blood vessel walls, the heart, and the kidneys. Losartan selectively blocks the AT1 receptor — the receptor through which angiotensin II exerts all these harmful effects. By blocking this receptor, Losartan causes blood vessels to relax and widen, reduces fluid retention, lowers blood pressure, and protects target organs from angiotensin II-mediated damage.
Kidney Protection in Diabetic Patients: In diabetic nephropathy, angiotensin II causes raised pressure inside the kidney's filtering units (glomeruli) — damaging the filtration barrier and causing protein to leak into urine (proteinuria). Losartan reduces this intraglomerular pressure — protecting the filtration barrier, reducing proteinuria, and slowing the progression of kidney disease independently of its blood pressure lowering effect.
Unique Uricosuric Effect: Unlike other ARBs, Losartan has a mild uricosuric effect — increasing uric acid excretion through the urine and mildly lowering serum uric acid levels. This makes Eziday 50mg the preferred ARB in hypertensive patients who also have gout or elevated uric acid levels.
Dosage and Administration
⚠️ Always take exactly as prescribed by your doctor. Never stop Eziday suddenly without medical advice — abrupt discontinuation can cause dangerous rebound hypertension.
| Indication | Usual Starting Dose | Frequency | Maximum Daily Dose |
|---|---|---|---|
| Hypertension | 50mg | Once daily | 100mg |
| Stroke prevention (LVH) | 50mg | Once daily | 100mg |
| Diabetic nephropathy | 50mg | Once daily | 100mg |
| Heart failure | 12.5–25mg | Once daily | 150mg (divided) |
| Elderly / Volume-depleted patients | 25mg | Once daily | 50mg |
Critical Dosing Rules:
- If blood pressure is not adequately controlled on 50mg after 3 to 4 weeks, your doctor may increase the dose to 100mg once daily — never increase the dose without medical advice
- Kidney function (creatinine and eGFR) and potassium levels must be checked before starting and monitored regularly throughout treatment — Losartan retains potassium and can impair kidney function particularly in dehydrated patients
- Avoid potassium supplements, potassium-rich salt substitutes, or potassium-sparing diuretics without your doctor's advice — dangerous hyperkalaemia risk
- Elderly patients and those with low blood volume should start at 25mg — higher sensitivity to first-dose blood pressure drop
- Never stop suddenly — always taper under your doctor's direct supervision
How to Take:
- Swallow the tablet whole with a full glass of water
- May be taken with or without food — take consistently the same way each day
- Take at the same time each day — consistent once-daily dosing maintains stable blood pressure control
- If a dose is missed, take it the same day as soon as remembered — skip if it is the next day; never double the dose

Who Should NOT Take Eziday 50mg?
Do not take if you:
- Are allergic to Losartan or any ingredient in the tablet
- Have diabetes and are also taking Aliskiren — combination is contraindicated
- Have severe liver disease or biliary cirrhosis
- Are pregnant — Losartan causes serious foetal harm and is strictly contraindicated in all trimesters (حمل میں سختی سے منع ہے)
- Are breastfeeding
- Have a history of angioedema with any ARB or ACE inhibitor — swelling of face or throat
Always consult your doctor before taking Eziday if you have:
- Any degree of kidney disease (گردے کی بیماری) — monitor kidney function and potassium regularly
- Mild to moderate liver disease — Losartan is extensively liver-metabolised; dose reduction may be required
- Bilateral renal artery stenosis — ARBs can cause dangerous kidney failure in this condition
- Heart failure — requires careful initiation under cardiologist supervision
- Low blood volume or dehydration — risk of severe first-dose hypotension
- Diabetes (ذیابیطس) — monitor potassium levels closely; Losartan retains potassium
- Gout (گنٹھیا) — Losartan is the preferred antihypertensive in gout due to its mild uric acid lowering effect
- Are elderly — start at 25mg; increased sensitivity to blood pressure lowering and falls risk
- Are taking ACE inhibitors, potassium supplements, or NSAIDs
Side Effects
Common Side Effects:
- Dizziness or light-headedness — particularly when standing up quickly (postural hypotension)
- Fatigue or tiredness — usually mild and temporary
- Headache — mild and typically improves with continued use
- Upper respiratory symptoms — mild cold-like symptoms including runny nose; ARB class effect
- Back pain or muscle cramps — Losartan related class effect
- Mild nausea or stomach discomfort — usually temporary
- Hyperkalaemia (raised potassium) — mild elevation common; serious levels require immediate attention
Serious Side Effects — Stop Taking and Seek Medical Help Immediately:
