Generic Cozaar Information

Introduction

Cozaar (Losartan potassium) is an oral antihypertensive medication indicated for the treatment of hypertension and for protecting the kidneys in patients with type 2 diabetes‑related nephropathy. It belongs to the class of angiotensin II receptor blockers (ARBs) and is widely prescribed in Hong Kong for both primary and secondary cardiovascular risk reduction. The drug is manufactured by Merck & Co. and is listed on the Hong Kong Department of Health’s medicines register. In addition to blood‑pressure control, Cozaar is approved for use in heart‑failure management and for reducing the risk of stroke in patients with left‑ventricular hypertrophy.

What is Cozaar?

Cozaar is a brand‑name formulation that contains the active compound Losartan potassium (50 mg, 100 mg, or 150 mg tablets). Losartan was first approved in the United States in 1995 and later introduced in Hong Kong under the Cozaar trademark. The drug is classified as an angiotensin II receptor blocker (ARB), a subclass of renin‑angiotensin‑system inhibitors. Cozaar is produced by Merck & Co. and distributed locally by authorized pharmaceutical importers.

Other well‑known Losartan‑based products include Hyzaar (Losartan + hydrochlorothiazide) and generic Losartan tablets marketed by various manufacturers. Patients who prefer a cost‑effective alternative can obtain the generic version of Losartan, which contains the same active ingredient as Cozaar.

How Cozaar Works

Losartan selectively blocks the binding of angiotensin II to the angiotensin II type 1 (AT₁) receptor on vascular smooth‑muscle cells and adrenal gland tissue. This inhibition prevents angiotensin II‑mediated vasoconstriction, aldosterone secretion, and sympathetic activation. The net effect is a reduction in systemic, lowered sodium‑water retention, and modest diuresis. Clinically, these mechanisms translate into a gradual decline in systolic and diastolic blood pressure, typically observable within 2 weeks of initiation. Losartan has a half‑life of approximately 2 hours for the parent drug and 6–9 hours for its active metabolite, EXP‑3174, which contributes to sustained antihypertensive activity over a 24‑hour dosing interval.

Conditions Treated with Cozaar

• Essential (primary) hypertension – Cozaar lowers both systolic and diastolic pressures, reducing the risk of myocardial infarction, stroke, and renal disease.
• Diabetic nephropathy (type 2 diabetes) – Clinical trials in Asian cohorts have demonstrated that Losartan slows the progression of albuminuria and preserves glomerular filtration rate.
• Heart failure with reduced ejection fraction – In combination with standard therapy, Losartan improves morbidity outcomes by decreasing after‑load and attenuating ventricular remodeling.
• Left‑ventricular hypertrophy – By reducing systemic pressure, Cozaar diminishes myocardial wall stress, lowering the incidence of stroke in this high‑risk group.

In Hong Kong, hypertension affects roughly 30 % of adults over 40 years, and the prevalence of diabetic kidney disease is rising alongside the region’s increasing diabetes burden. Cozaar addresses both conditions, offering a dual‑benefit strategy for many patients.

Patient Groups Most Likely to Benefit

• Adults with newly diagnosed or uncontrolled hypertension who require a once‑daily oral agent.
• Patients with type 2 diabetes and micro‑albuminuria where renal protection is a priority.
• Individuals with chronic heart failure already receiving ACE‑inhibitors or β‑blockers and needing additional after‑load reduction.
• Elderly patients who may be intolerant to ACE‑inhibitor–related cough; ARBs such as Cozaar are less likely to provoke this adverse effect.

Contra‑indications include severe hepatic impairment, pregnancy, and known hypersensitivity to Losartan or any component of the tablet. Caution is advised in patients with bilateral renal artery stenosis or those on potassium‑sparing diuretics.

Risks, Side Effects, and Interactions

Common

• Dizziness, especially after the first dose or when standing up quickly (orthostatic hypotension)
• Headache
• Nasal congestion
• Fatigue

Rare

• Hyperkalemia (elevated blood potassium)
• Elevated serum creatinine or reduced eGFR in patients with pre‑existing renal disease
• Ankle edema

Serious

• Angio‑edema (swelling of lips, tongue, or throat) – rare but potentially life‑threatening
• Severe hypotension leading to syncope or falls, particularly in volume‑depleted individuals
• Acute kidney injury in the setting of concurrent nephrotoxic agents or renal artery stenosis

Drug–drug interactions

• Potassium‑rich supplements or potassium‑sparing diuretics (e.g., spironolactone): increase risk of hyperkalemia.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs): may blunt antihypertensive effect and impair renal function.
• Lithium: Losartan can raise lithium levels, precipitating toxicity; close monitoring is required.
• Concomitant ACE inhibitors or other ARBs: combined use heightens the risk of renal dysfunction, hyperkalemia, and hypotension and is generally avoided.

Patients should disclose all prescription, over‑the‑counter, and herbal products to their healthcare provider before initiating Cozaar.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dosing for hypertension:

  • Initiation: 50 mg once daily.
  • titration: increase to 100 mg once daily after 2 weeks if target blood pressure is not achieved.
  • Maximum: 100 mg daily; some patients may be escalated to 150 mg under specialist supervision.

• Diabetic nephropathy: 50 mg once daily, with dose adjustment based on renal function.

• Heart failure: 12.5–50 mg once daily, often combined with other heart‑failure agents.

• Missed dose: Take the forgotten tablet as soon as remembered unless it is close to the time of the next scheduled dose; in that case, skip the missed tablet and continue the regular regimen. Do not double‑dose.

• Overdose: Symptoms may include severe hypotension, fainting, or renal dysfunction. Immediate medical attention is required. Management is supportive, focusing on blood pressure stabilization and monitoring of renal indices.

• Food and alcohol: Cozaar can be taken with or without food. Excessive alcohol may exacerbate hypotension and should be avoided.

• Comorbidities: Patients with hepatic impairment may need lower initial doses; dose adjustment is not required for mild to moderate renal impairment but is advised for severe renal dysfunction (eGFR < 30 mL/min/1.73 m²).

FAQ

• Is Cozaar covered by the Hong Kong Hospital Authority’s drug formulary?
  The Hospital Authority includes Losartan (generic) in its formulary for hypertension, but coverage may depend on the specific clinical pathway and patient eligibility. Private insurance plans vary; some may reimburse the brand‑name Cozaar if a generic alternative is not deemed appropriate.

• Can Cozaar be taken during pregnancy or breastfeeding?
  Losartan is contraindicated in pregnancy because it can cause fetal renal dysplasia and other congenital anomalies. Women of child‑bearing potential should use effective contraception while on Cozaar. Limited data exist for lactation; it is generally advised to avoid breastfeeding during treatment unless the benefit outweighs the potential risk.

• How does Cozaar compare with ACE inhibitors for blood‑pressure control?
  Both drug classes achieve comparable reductions in systolic and diastolic pressure. However, ARBs such as Cozaar are less likely to cause a dry cough and angio‑edema, making them preferable for patients who experience these side effects with ACE inhibitors.

• What monitoring is required while on Cozaar?
  Baseline and periodic measurement of blood pressure, serum potassium, and renal function (creatinine, eGFR) are recommended, especially within the first month of therapy and after any dose adjustment.

• Are there any ethnic‑specific dosage considerations for Asian patients?
  Clinical studies suggest that Asian populations may achieve target blood pressure with lower initial doses (e.g., 25 mg) due to differences in body mass and pharmacogenomics. Physicians often start at 50 mg but may individualize dosing based on response and tolerance.

• Can Cozaar be combined with a thiazide diuretic?
  Yes, fixed‑dose combinations such as Hyzaar (Losartan + hydrochlorothiazide) are available and commonly used to enhance antihypertensive efficacy while simplifying the pill burden.

• Is a special storage condition required for Cozaar tablets?
  Cozaar should be stored at room temperature (15‑30 °C), protected from moisture, direct sunlight, and excessive heat. No refrigeration is needed.

• What is the legal status of importing Cozaar for personal use into Hong Kong?
  The import of prescription medication for personal use is permitted when the importer holds a valid prescription issued by a licensed Hong Kong practitioner. Our online pharmacy assists customers in obtaining the required professional evaluation to satisfy local regulatory requirements.

• How does the professional evaluation process work for online orders?

• Can Cozaar be used in patients with chronic liver disease?
  Losartan is primarily eliminated unchanged and via hepatic metabolism of its active metabolite. Mild to moderate hepatic impairment does not usually require dose adjustment, but severe liver disease may increase plasma concentrations of the metabolite, warranting careful monitoring and possibly a lower starting dose.

• Is there a difference between US‑approved and Asian‑market Cozaar tablets?
  The active ingredient, Losartan potassium, is identical across regions. Excipients may differ slightly to meet local regulatory standards, but therapeutic efficacy and safety profiles remain equivalent.

• What should I do if I experience a persistent cough while taking Cozaar?
  A cough is uncommon with ARBs, but if it occurs, it may indicate an unrelated condition such as asthma or upper‑respiratory infection. Contact your healthcare provider for assessment; they may consider switching to an alternative antihypertensive class if the symptom is bothersome.
