Improvement in blood pressure control when hypertension is poorly controlled by monotherapy
This medication is used for patients with hypertension whose blood pressure is not adequately controlled with monotherapy. It effectively lowers blood pressure, reducing the burden on the cardiovascular system and helping to prevent complications.
The usual dose for this medication is one tablet of Losartan Potassium 50 mg/Hydrochlorothiazide 12.5 mg once daily. A dose exceeding Losartan Potassium 100 mg/Hydrochlorothiazide 25 mg per day is not recommended. 1. Start therapy with Losartan Potassium 50 mg/Hydrochlorothiazide 12.5 mg once daily; if blood pressure remains uncontrolled after three weeks of use, the maximum dose of Losartan Potassium 100 mg/Hydrochlorothiazide 25 mg once daily may be used for increase. 2. Patients whose blood pressure is not controlled with single therapy of Losartan or Hydrochlorothiazide: start with Losartan Potassium 50 mg/Hydrochlorothiazide 12.5 mg once daily; if blood pressure remains uncontrolled after three weeks, the dose may be increased to Losartan Potassium 100 mg/Hydrochlorothiazide 25 mg once daily. 3. For patients whose blood pressure is not controlled with a single therapy of Losartan Potassium 100 mg: Start with Losartan Potassium 100 mg/Hydrochlorothiazide 12.5 mg once daily; if blood pressure is still not controlled after three weeks, the dose may be increased to Losartan Potassium 100 mg/Hydrochlorothiazide 25 mg once daily. 4. For patients whose blood pressure is not controlled with 25 mg of Hydrochlorothiazide once daily or who exhibit hypokalemia at this dose: start with Losartan Potassium 50 mg/Hydrochlorothiazide 12.5 mg once daily, which can reduce the overall antihypertensive effect without decreasing Hydrochlorothiazide dosage. If blood pressure remains uncontrolled after three weeks, the dose may be increased to Losartan Potassium 100 mg/Hydrochlorothiazide 25 mg once daily. ○ For patients with renal impairment For patients with a creatinine clearance of 30 mL/min or more, the usual dose may be administered. For more severe renal impairment, it is preferable to use loop diuretics rather than thiazide medications, so administration in these patients is not recommended. ○ For patients with liver impairment The initial dose of 25 mg of Losartan Potassium for patients with liver impairment requiring dose adjustment cannot be given with this medication, so administration in these patients is not recommended. ○ For children (under 18 years old) There is no experience in using this medication in children and adolescents, so the combination of Losartan and Hydrochlorothiazide is not to be given to children and adolescents.
There is no experience in using this medication in children and adolescents, so the combination of Losartan and Hydrochlorothiazide is not to be given to children and adolescents.
This drug can cause serious harm to the fetus if taken during pregnancy, especially in the second and third trimesters, so it must be discontinued immediately upon confirmation of pregnancy. There is a risk of complications for the fetus during pregnancy, such as decreased lung development, skeletal malformations, decreased skull formation, and renal failure, which can even lead to neonatal death. This medication should not be administered to patients with certain conditions, for example, those with anuria, severe liver dysfunction, severe kidney dysfunction, or allergies to sulfonamide drugs. Patients with electrolyte imbalances, such as hyperuricemia, gout, hypokalemia, hypercalcemia, and hyponatremia, should be careful. Elderly patients and those with cardiovascular diseases, cerebrovascular disorders, or diabetes may experience excessive hypotensive effects or worsening conditions, so treatment should be cautious. This medication affects potassium concentration, so taking it with potassium supplements or potassium-sparing diuretics may be dangerous; consultation with a doctor is required before taking. During treatment, blood pressure, kidney function, and electrolyte levels should be regularly monitored to ensure no abnormalities occur. Dizziness or drowsiness may occur while taking this medication, so caution is necessary when driving or operating machinery.

In the case of overdose, symptoms may include hypotension and arrhythmias, and medical attention should be sought immediately.
