Lopressor HCT is used in the treatment of hypertension (high blood pressure). Metoprolol is a selective beta-1 blocker. It works on the heart and decreases heart rate. It also prevents the release of renin in the kidney (a hormone which causes vessels constriction) and so dilates and relaxes vessels, which lowers blood pressure to normal and increases the supply of oxygen and blood to the heart.
Hydrochlorothiazide is a thiazide diuretic (water pill). It prevents absorption of salt in kidney and increases excretion of water in urine and so decreasing amount of water (fluids) in the body which decreases pressure on vessels.
It is available in the form of the tablet only with doctor’s prescription.
