Drug Class: Angiotensin II Receptor Blocker (ARB) | Form: Oral Tablet | Prescription Status: Prescription Only (Rx) — DRAP Registered
What is Eziday 100mg Tablet? Eziday 100mg contains Losartan Potassium — the first ARB ever developed and one of the most extensively studied angiotensin receptor blockers with over three decades of proven clinical use. The 100mg strength is the maximum approved Losartan dose — prescribed for patients whose hypertension, diabetic nephropathy, or cardiovascular risk reduction requires stronger angiotensin II blockade than the standard 50mg dose achieves. Losartan has the unique additional benefit of lowering uric acid levels — making it particularly advantageous for hypertensive patients with gout or hyperuricaemia where most other antihypertensives are neutral or worsen uric acid levels. Like all ARBs it does not cause the persistent dry cough associated with ACE inhibitors — improving long-term treatment compliance significantly compared to ACE inhibitor therapy.
What is Eziday 100mg Used For?
- Hypertension — maximum dose for blood pressure inadequately controlled on 50mg (ہائی بلڈ پریشر)
- Cardiovascular risk reduction — reducing stroke risk in hypertensive patients with left ventricular hypertrophy (فالج کی روک تھام)
- Diabetic nephropathy — slowing kidney disease progression in Type 2 diabetic patients with proteinuria (ذیابیطس میں گردوں کی حفاظت)
- Heart failure — as alternative to ACE inhibitors in patients who cannot tolerate ACE inhibitor cough
- Hypertension with gout or hyperuricaemia — Losartan uniquely lowers uric acid levels (یورک ایسڈ کم کرنے میں مددگار)
- Chronic kidney disease — reducing proteinuria and slowing progression in diabetic kidney disease
How Does it Work? Losartan selectively blocks AT1 angiotensin II receptors — preventing angiotensin II from causing vasoconstriction, aldosterone secretion, sodium retention, and pathological cardiac and renal remodelling. At 100mg this AT1 receptor blockade is more complete and sustained than at 50mg — providing stronger blood pressure reduction and more comprehensive organ protection. Losartan is converted in the liver to its active metabolite E-3174 which has significantly higher AT1 receptor affinity and a longer half-life — contributing to the sustained antihypertensive effect throughout the full 24-hour dosing period. Losartan additionally inhibits uric acid reabsorption in the renal tubule through a uricosuric mechanism — uniquely lowering serum uric acid levels and providing added benefit in hypertensive patients with gout.
Dosage and Administration
⚠️ Never stop suddenly — abrupt discontinuation causes dangerous rebound hypertension. Takes 3 to 6 weeks for full blood pressure lowering effect at 100mg. Monitor kidney function and blood potassium regularly. Can be taken with or without food. Correct volume depletion before starting or escalating dose.
| Indication | Usual Adult Dose | Frequency | Notes |
|---|---|---|---|
| Hypertension — maximum dose | 100mg | Once daily | When 50mg provides insufficient control |
| Diabetic nephropathy | 100mg | Once daily | With or without other antihypertensives |
| Cardiovascular risk reduction | 100mg | Once daily | In patients with LVH — as prescribed |
| Heart failure | 50 – 100mg | Once daily | Under cardiologist supervision |
| Hypertension with gout | 100mg | Once daily | Uricosuric benefit maximised at higher dose |

Who Should NOT Take Eziday 100mg?
- Allergy to Losartan or any ARB medicine
- Pregnancy — strictly contraindicated in all trimesters; causes serious foetal kidney damage and death
- Breastfeeding
- Severe liver impairment — Losartan extensively hepatically metabolised to active form
- Severe kidney impairment or bilateral renal artery stenosis
- Concurrent use of Aliskiren in patients with diabetes or kidney impairment
- Hereditary angioedema or prior angioedema with any ARB or ACE inhibitor
- Severe hypotension — systolic blood pressure below 90mmHg
- Significant volume or sodium depletion — correct before starting 100mg dose
Side Effects
Common: Mild dizziness especially on standing (اٹھتے وقت چکر — خاص طور پر 100mg پر), mild headache, mild fatigue, mild upper respiratory symptoms — extremely well tolerated at this highest dose; notably no dry cough unlike ACE inhibitors. Mild hyperkalaemia — potassium level rise usually within normal range at standard doses.
Serious — Stop and seek emergency help immediately: Angioedema — sudden swelling of face, lips, tongue or throat with breathing difficulty (چہرے اور گلے کی سوجن — فوری ہسپتال جائیں), severely low blood pressure with fainting particularly after first dose escalation to 100mg (بے ہوشی — فوری مدد لیں), dangerous hyperkalaemia — severe muscle weakness and irregular heartbeat from elevated potassium (پٹھوں کی کمزوری اور دل کی دھڑکن میں خلل — فوری ڈاکٹر کو بتائیں), significant worsening of kidney function — reduced urination with ankle swelling and weight gain, severe allergic reaction with widespread rash, significant liver toxicity — yellowing of skin or eyes (یرقان — فوری مدد لیں).
Drug Interactions
| Medicine | Interaction |
|---|---|
| ACE inhibitors (Enalapril, Lisinopril) | Significantly increased hyperkalaemia and acute kidney failure risk — avoid dual RAAS blockade |
| Aliskiren | Increased hyperkalaemia and kidney damage risk — contraindicated in diabetes and kidney disease |
| Potassium supplements / Potassium-sparing diuretics | Significantly increased hyperkalaemia risk — monitor potassium closely at 100mg dose |
| NSAIDs (Ibuprofen, Diclofenac) | Reduce antihypertensive effectiveness and significantly worsen kidney function — avoid regular combined use |
| Fluconazole | Inhibits Losartan conversion to active metabolite E-3174 — significantly reduces antihypertensive effectiveness |
| Rifampicin | Reduces Losartan and active metabolite blood levels — reduced antihypertensive effectiveness |
| Lithium | Losartan increases Lithium blood levels — toxicity risk; monitor closely |
| Antidiabetic medicines | Losartan may enhance hypoglycaemic effect — monitor blood glucose in diabetic patients |
| Other antihypertensives / diuretics | Additive blood pressure lowering — particularly significant when escalating to 100mg dose |
| Alcohol (شراب) | Increases blood pressure lowering and dizziness risk — avoid excessive consumption |

FAQs
Q: Why is Losartan in Eziday particularly beneficial for hypertensive patients who also have gout? Losartan uniquely inhibits uric acid reabsorption in the renal proximal tubule through a uricosuric mechanism — actively increasing urinary uric acid excretion and lowering serum uric acid levels. This benefit is unique among ARBs and most antihypertensives — making Eziday the preferred antihypertensive choice for patients with both hypertension and gout or hyperuricaemia where other antihypertensives are uric acid neutral or worsen levels.
Q: When should Eziday be escalated from 50mg to the maximum 100mg dose? If blood pressure remains inadequately controlled after 3 to 6 weeks of consistent once-daily 50mg use — your cardiologist will assess whether escalation to 100mg is appropriate. The 100mg dose provides significantly stronger AT1 receptor blockade and greater blood pressure reduction — particularly important for diabetic nephropathy where maximum RAAS blockade provides the greatest kidney protection benefit.
Q: Is Eziday 100mg safe for patients with Type 2 diabetes and kidney disease? Yes — Losartan 100mg is specifically indicated for Type 2 diabetic patients with nephropathy and proteinuria where clinical trials demonstrated significant slowing of kidney disease progression beyond simple blood pressure control. Regular monitoring of kidney function, blood potassium, and urine protein is essential throughout treatment — your nephrologist and diabetologist will guide the optimal monitoring frequency based on your individual kidney function level.
