1. What is Lozap HCT and what is it used for

Lozap HCT is a combination medicine containing an angiotensin II receptor antagonist (losartan) and a diuretic (hydrochlorothiazide). Angiotensin II is a substance produced by the body that binds to receptors in blood vessels, causing them to narrow. This results in increased blood pressure. Losartan prevents angiotensin II from binding to these receptors, causing blood vessels to widen, and consequently, lowering blood pressure. Hydrochlorothiazide increases the excretion of water and salt by the kidneys. This also helps to lower blood pressure.
Lozap HCT is indicated for the treatment of primary hypertension (high blood pressure).

2. Important information before taking Lozap HCT

When not to take Lozap HCT

if the patient is allergic to losartan, hydrochlorothiazide, or any of the other ingredients of this medicine (listed in section 6);
if the patient is allergic to other sulfonamide-derived substances (e.g., other thiazide diuretics, certain antibacterial drugs, such as cotrimoxazole - in case of doubt, consult a doctor);
if the patient has severe liver dysfunction;
if the patient has low potassium, low sodium, or high calcium levels in the blood that cannot be corrected by treatment;
if the patient has gout;
