Accuretic 10/12.5mg (Quinapril/HCTZ)

Accuretic general information

What is Accuretic used for?

Accuretic tablets 10/12.5mg are a fixed dose combination medication used to treat hypertension, in people whose blood pressure cannot be controlled by a single medication.  Although there are usually no other symptoms, essential hypertension, which is high blood pressure when at rest with usually no obvious and identifiable cause, increases risk of cardiovascular disease and if uncontrolled can cause kidney damage, stroke, heart attack and heart failure.  Accuretic tablets 10/12.5mg lower blood pressure to normal resting levels, which helps the heart to cope better and reduces the risk of cardiovascular disease and end organ damage.  

How does Accuretic work?

Accuretic tablets 10/12.5mg contain a fixed dose combination of two medications that work together to reduce blood pressure, in a way that is more effective that if each drug is used alone.  Quinapril is an Angiotensin Converting Enzyme (ACE) inhibitor that prevents the formation of angiotensin II, a hormone that has several actions involved in regulating blood pressure, which is the force needed to pump blood around the body.  Angiotensin II causes salt and water retention by the kidneys, and causes blood vessels to constrict (narrow); this increases blood volume while at the same time reducing blood vessel volume, which increases blood pressure.  Quinapril in Accuretic tablets 10/12.5mg inhibits the conversion of angiotensin II from angiotensin I, which allows blood vessels to relax and widen, reducing the force needed by the heart to pump blood around the body, reducing its workload and lowering blood pressure.  Hydrochlorothiazide is a thiazide diuretic and acts directly on the distal convoluted tubule of the kidneys to promote the removal of salts and water from the blood.  It works by inhibiting reabsorption of salts (sodium and chloride ions) back into the blood in the kidney tubules, and this action promotes excretion of salt along with water, which increases urine volume and decreases blood volume.  The combined action of quinapril and hydrochlorothiazide in Accuretic tablets 10/12.5mg provides a significant and additive reduction in blood pressure, which is maintained for as long as you take your Accuretic tablets 10/12.5mg

Treating hypertension (high blood pressure) with Accuretic

Accuretic tablets 10/12.5mg contain a fixed dose combination of two medications that are used to treat hypertension, which is high blood pressure when at rest, in people whose blood pressure cannot be controlled by a single medication.  Blood pressure is the force needed to pump blood around the body and if too high can increase risk of cardiovascular disease, resulting in kidney damage, stroke, heart attack and heart failure.  The two antihypertensive drugs work together to reduce blood pressure, by causing relaxing and widening of blood vessels (vasodilation) and by increasing the removal water and salt from the blood, in a way that is more effective than if each drug is used alone.  Quinapril is an Angiotensin Converting Enzyme (ACE) inhibitor that prevents the formation of angiotensin II, a hormone that has several actions involved in regulating blood pressure.  Angiotensin II causes salt and water retention by the kidneys, and causes blood vessels to constrict (narrow); this increases blood volume while at the same time reducing blood vessel volume, which increases blood pressure.  Quinapril in Accuretic tablets 10/12.5mg inhibits the conversion of angiotensin II from angiotensin I, which allows blood vessels to relax and widen lowering blood pressure.  Hydrochlorothiazide in Accuretic tablets 10/12.5mg is a diuretic and acts directly on the kidneys and also promotes the removal of salts and water from the blood, which increases urine volume and decreases blood volume.  The combined action of quinapril and hydrochlorothiazide in Accuretic tablets 10/12.5mg lowers blood pressure to normal resting levels, which helps the heart to cope better and reduces the risk of cardiovascular disease and end organ damage.

• are taking Co-trimoxazole (Sulphamexthoxazole/Trimethoprim) [Trusul/Bactrim DS]

What medications interact with Accuretic?

Several medications interact with Accuretic tablets 10/12.5mg and should either not be taken while you are taking Accuretic or only after discussion and instruction from your doctor:
