Lisoretic 10mg/12.5mg №14×2: Effective Hypertension Treatment
Discover Lisoretic, a potent combination of lisinopril and hydrochlorothiazide, designed to effectively manage mild to moderate hypertension. This comprehensive guide will provide you with a detailed understanding of Lisoretic’s composition, mechanism of action, dosage, potential side effects, and interactions with other medications.
Key Features:
- Dual-action formula: Combines the blood pressure-lowering benefits of lisinopril (an ACE inhibitor) and hydrochlorothiazide (a thiazide diuretic) for a synergistic effect.
- Convenient once-daily dosing: Requires just one tablet per day for consistent blood pressure control.
- Available in two strengths: Lisoretic 10mg/12.5mg and Lisoretic 20mg/12.5mg, allowing for tailored dosage adjustments.
Composition:
Lisoretic 10mg/12.5mg tablet contains:
- Active ingredients: Lisinopril (as lisinopril dihydrate) 10.00 mg and hydrochlorothiazide 12.50 mg
- Excipients: Calcium hydrogen phosphate 38.01 mg, mannitol 22.00 mg, corn starch 22.40 mg, pregelatinized starch 3.00 mg, iron dye red oxide (E172) 0.05 mg, iron dye yellow oxide (E172) 0.05 mg, magnesium stearate 1.10 mg.
Lisoretic 20mg/12.5mg tablet contains:
- Active ingredients: Lisinopril (as lisinopril dihydrate) 20.00 mg and hydrochlorothiazide 12.50 mg
- Excipients: Calcium hydrogen phosphate 88.72 mg, mannitol 44.00 mg, corn starch 44.80 mg, pregelatinized starch 6.00 mg, magnesium stearate 2.20 mg.
Mechanism of Action:
Lisoretic acts by effectively lowering blood pressure through two complementary mechanisms:
- Lisinopril: Blocks the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor, leading to vasodilation and reduced blood pressure.
- Hydrochlorothiazide: Increases urine production by promoting sodium and chloride excretion, further contributing to blood pressure reduction.
Dosage and Administration:
- Typical Dosage: One tablet (10mg/12.5mg or 20mg/12.5mg) daily, taken at the same time each day.
- Dosage Adjustments: Dose can be increased to two tablets daily if necessary, after careful evaluation by your doctor.
- Renal Insufficiency: Use with caution in patients with renal impairment; consult your doctor for appropriate dosage adjustment.
- Elderly Patients: Dosage may need to be adjusted based on individual needs; consult your doctor for personalized recommendations.
