LOSARK-H Tablet is a fixed-dose combination of Losartan Potassium and Hydrochlorothiazide, used to treat high blood pressure (hypertension). It effectively lowers blood pressure by relaxing blood vessels and promoting the excretion of excess salt and water, thereby reducing the risk of heart attack, stroke, and kidney problems.

This product is manufactured under the Dr Precision label, ensuring GMP-compliant quality and precision formulation standards.

LOSARK-H Tablet is a well-established combination medication comprising Losartan Potassium, an angiotensin II receptor blocker (ARB), and Hydrochlorothiazide, a thiazide diuretic. This dual-action antihypertensive therapy is designed to manage mild to moderate hypertension, particularly in patients whose blood pressure is not adequately controlled by monotherapy. By addressing two different mechanisms of action, LOSARK-H offers a synergistic and more potent effect on lowering elevated blood pressure levels, thus playing a vital role in cardiovascular and renal protection.

Losartan Potassium, the primary component of LOSARK-H, selectively blocks the angiotensin II receptor type 1 (AT1), which is responsible for vasoconstriction and aldosterone secretion. By inhibiting the effects of angiotensin II, Losartan causes the blood vessels to relax, leading to a decrease in systemic vascular resistance and subsequently lowering blood pressure. It also reduces the secretion of aldosterone, a hormone that retains sodium and water, thus contributing further to blood pressure reduction.

Hydrochlorothiazide complements the action of Losartan by acting on the distal convoluted tubules in the kidneys, where it inhibits sodium and chloride reabsorption. This diuretic effect leads to increased excretion of sodium, chloride, and water, reducing plasma volume and blood pressure. Additionally, the mild potassium-retaining effect of Losartan helps offset the potassium loss commonly associated with diuretics, making the combination more balanced and safer over long-term use.

LOSARK-H Tablet is clinically proven to provide superior blood pressure control compared to monotherapies, especially in patients with coexisting conditions such as diabetes mellitus, chronic kidney disease, or heart failure. It reduces the workload on the heart and prevents complications such as left ventricular hypertrophy, stroke, myocardial infarction, and progression of kidney dysfunction.

This medication is typically administered once daily, preferably in the morning, with or without food. Its 24-hour antihypertensive effect ensures consistent blood pressure control, improving adherence and treatment outcomes. It is well-tolerated by most patients, with side effects being generally mild and transient. Common adverse reactions may include dizziness, fatigue, headache, increased urination, or electrolyte imbalances. Rarely, hypersensitivity reactions or hypotension may occur, especially in volume-depleted individuals.

LOSARK-H is contraindicated during pregnancy, particularly in the second and third trimesters, due to the risk of fetal toxicity. It should also be used cautiously in patients with severe renal impairment, hepatic dysfunction, or those on potassium supplements or potassium-sparing diuretics. Regular monitoring of renal function, electrolytes, and blood pressure is advisable during prolonged therapy.

Manufactured under WHO-GMP and ISO-certified facilities, LOSARK-H Tablet meets global quality standards for efficacy, purity, and safety. The formulation is available in tamper-evident, moisture-resistant packaging that preserves its stability and extends shelf life. Advanced manufacturing protocols ensure uniformity of dosage and compliance with pharmacopeial specifications.

LOSARK-H is an integral part of modern antihypertensive therapy protocols. Its ability to offer additive or even synergistic effects in controlling blood pressure makes it a preferred choice among clinicians treating patients with essential hypertension or at risk of cardiovascular complications. In clinical practice, it is often selected when monotherapy proves insufficient or when a combination strategy is needed for rapid and sustained results.

In summary, LOSARK-H Tablet represents a comprehensive and dependable solution for hypertension management. Its dual mechanism of action, favorable safety profile, and once-daily dosing schedule contribute to its widespread acceptance and clinical efficacy. Whether used as a step-up therapy or part of an initial fixed-dose strategy, LOSARK-H plays a critical role in improving blood pressure outcomes and reducing long-term cardiovascular risk.
