HOW SUSTAMETO 25MG TABLET WORKS

In hypertension, SUSTAMETO 25MG TABLET works by blocking the effect of adrenaline on the heart and decreasing cardiac output, also reducing the outflow of sympathetic neurons, and suppressing renin activity (normally responsible for the increase in blood pressure). Together, these actions lower blood pressure effectively.

In angina pectoris, SUSTAMETO 25MG TABLET works by blocking adrenaline effects on the heart and decreases the heart rate, blood pressure, and extent of heart contraction. It also reduces the oxygen requirements of the heart, providing relief from angina.

In heart failure, SUSTAMETO 25MG TABLET slows down the heart rate and makes it easier for the heart to pump blood around the body.
