About Losartan
Losartan is a widely prescribed oral medication used to manage high blood pressure and protect the heart and kidneys from the damaging effects of excess angiotensin II. As an angiotensin II receptor blocker (ARB), it helps relax blood vessels, lower systemic vascular resistance, and reduce the workload on the heart. Clinicians commonly prescribe it for hypertension, heart failure, and to slow the progression of diabetic kidney disease. In Australia, Losartan is available only by prescription and is supplied in tablet form at strengths of 25 mg, 50 mg, and 100 mg.
What is Generic Losartan?
Generic Losartan is an angiotensin II receptor blocker approved by the Therapeutic Goods Administration (TGA) for the treatment of hypertension, heart failure, and renal protection in patients with type 2 diabetes. The drug is marketed as a tablet that can be taken once daily, and it is listed on the Australian Pharmaceutical Benefits Scheme (PBS) for eligible patients. Although the brand name Cozaar is well known, the generic version offers the same clinical benefit at a lower cost.
How Losartan Works
Losartan selectively blocks the AT₁ receptors that bind angiotensin II, the hormone responsible for vasoconstriction, aldosterone release, and sympathetic activation. By preventing this binding, Losartan - and its active metabolite EXP-3174 - induces vasodilation, reduces sodium and water retention, and blunts maladaptive cardiac remodeling. After oral ingestion, Losartan is rapidly absorbed, reaching peak plasma concentrations within about one hour. It undergoes hepatic metabolism via CYP2C9 and CYP3A4 to form EXP-3174, which has a longer half-life (6-9 hours) than the parent compound (≈2 hours) and contributes most of the antihypertensive effect. The combined action provides sustained blood-pressure control over a 24-hour dosing interval.
Why Losartan Is Used for Cardiovascular Conditions
- Hypertension: By inhibiting AT₁ receptors, Losartan lowers systemic vascular resistance, resulting in an average systolic reduction of 8-10 mmHg. Guidelines from the National Health and Medical Research Council (NHMRC) place ARBs as first-line options, especially in patients who experience cough with ACE inhibitors.
- Heart Failure with Reduced Ejection Fraction: Losartan improves survival and reduces hospitalisation rates by attenuating ventricular remodeling and neurohormonal activation. The PARADIGM-HF trial demonstrated comparable outcomes to enalapril, making it a viable alternative when ACE inhibitors are not tolerated.
- Diabetic Nephropathy: In the RENAAL study, Losartan slowed the decline in glomerular filtration rate and reduced proteinuria by roughly 30 % compared with placebo, supporting its inclusion in renal-protective protocols for type 2 diabetes.
- Stroke Risk Reduction: Post-stroke patients with hypertension benefit from Losartan’s ability to maintain stable blood-pressure control, which correlates with lower recurrence rates.
- Aortic Root Dilatation in Marfan Syndrome (off-label): Small-scale studies suggest that ARBs may limit aortic growth, though larger trials are needed to confirm efficacy.
Off-Label and Investigational Uses of Losartan
Research has explored Losartan in conditions such as chronic kidney disease unrelated to diabetes, pulmonary hypertension, and even as an adjunct in certain cancers where angiotensin II contributes to tumor angiogenesis. These applications remain investigational and are not approved by the TGA. Off-label use should only be considered under the supervision of a qualified healthcare provider.
Is Losartan Right for You?
Losartan suits adults with elevated blood pressure, chronic heart failure, or diabetic kidney disease who need a well-tolerated oral agent. It is particularly appropriate for patients who develop dry cough or angio-edema with ACE inhibitors. Caution is advised in pregnancy (category D) and in individuals with severe hepatic impairment, as dosage adjustments may be required. Elderly patients often respond well to low-dose initiation (25 mg) with gradual titration. Renal function should be monitored, especially when combined with diuretics or NSAIDs, because of the risk of acute kidney injury.
Taking Losartan Effectively
- Timing: Take the tablet at the same time each day, preferably in the morning, to maintain steady plasma levels.
- Food Interaction: Losartan’s absorption is not significantly affected by meals, so it can be taken with or without food.
- Missed Dose: If you miss a dose and it is within 12 hours of the next scheduled dose, skip the missed tablet and resume the regular schedule. Do not double the dose.
- Travel Tips: Carry the medication in its original container, keep it away from excessive heat, and bring a copy of the prescription in case of customs checks.
- Lifestyle Integration: Pair Losartan therapy with sodium-restricted diet, regular aerobic exercise, and limiting alcohol to enhance blood-pressure control.
Understanding Side Effects and How to Manage Them
Most patients tolerate Losartan well, but some experience adverse effects linked to its pharmacology.
- Dizziness or Light-headedness: Result from lowered blood pressure, especially after the first dose. Stand up slowly, stay hydrated, and avoid abrupt position changes.
- Hyperkalemia: Blockade of aldosterone can raise serum potassium. Periodic blood tests are advisable; limit high-potassium foods if levels rise.
- Renal Function Changes: Reduced glomerular filtration pressure may transiently increase serum creatinine. Monitor kidney function after initiation or dose changes.
- Rare Reactions: Angio-edema, hepatic enzyme elevations, or severe allergic responses require immediate medical attention. If side effects become bothersome or persist beyond a few weeks, contact your healthcare provider for possible dose adjustment or alternative therapy.

Frequently Asked Questions
-
What should I do if I feel a sudden drop in blood pressure after starting Losartan? Light-headedness can occur initially. Sit or lie down, drink water, and avoid driving until you know how the medication affects you. If symptoms persist, contact your prescriber.
-
Can Losartan be taken with other blood-pressure medicines? Yes, it is often combined with thiazide diuretics or calcium-channel blockers for synergistic control, but a clinician should guide the combination to avoid excessive lowering of blood pressure.
-
Is Losartan safe for people with mild kidney disease? Losartan is actually beneficial in slowing kidney damage, but renal function should be checked before starting and periodically thereafter, especially if other nephrotoxic drugs are used.
-
Why might my lab results show higher potassium after beginning Losartan? Blocking aldosterone reduces potassium excretion. Your doctor may recommend dietary potassium moderation or adjust the dose if levels become too high.
-
How does Losartan differ from ACE inhibitors? Both target the renin-angiotensin system, but ACE inhibitors block the conversion of angiotensin I to II, while Losartan blocks the receptor directly. Losartan rarely causes the dry cough associated with ACE inhibitors.
-
Will Losartan help reduce my risk of heart attack? By lowering blood pressure and mitigating adverse cardiac remodeling, Losartan contributes to overall cardiovascular risk reduction, though direct evidence for heart-attack prevention is less robust than for stroke and heart-failure outcomes.
-
Can I use Losartan during pregnancy? Losartan is contraindicated in pregnancy because it may harm the developing fetus. Alternative antihypertensives, such as labetalol, are preferred.
-
Is there any benefit to taking Losartan in the evening instead of the morning? Pharmacokinetic data show consistent 24-hour coverage regardless of timing. Choose a time that fits your routine and helps maintain adherence.
-
Do I need to continue Losartan for life? Hypertension often requires long-term therapy. Your physician will assess blood-pressure trends and may taper the medication only if sustained control is achieved without it.
-
What happens if I miss several doses? Resume the regular schedule after a missed dose; do not double up. If you miss more than two consecutive doses, contact your prescriber for guidance.
