How do Quinapril, Istin and Bendrofluazide tablets work?
Answers:
Quinapril is used alone or in combination with other medications to treat high blood pressure. It is used in combination with other medications to treat heart failure. Quinapril is in a class of medications called angiotensin-converting enzyme (ACE) inhibitors. Istin works by decreasing certain chemicals that tighten the blood vessels, so blood flows more smoothly and the heart can pump blood more efficiently Istin tablets contain the active ingredient amlodipine besilate, which is a type of medicine called a calcium channel blocker. (NB. Amlodipine tablets are also available without a brand name, ie as the generic medicine.) Calcium channel blockers act on the heart and blood vessels.
Amlodipine works by slowing the movement of calcium through the muscle cells that are found in the walls of blood vessels. It does this by blocking 'calcium channels' in these muscle cells. Calcium is needed by muscle cells in order for them to contract, so by depriving them of calcium, amlodipine causes the muscle cells to relax.
Amlodipine acts specifically on the muscle cells in the walls of arteries, causing them to relax. This allows the arteries in the body to widen, an effect that has two main uses.
The relaxing and widening of the small arteries in the body decreases the resistance that the heart has to push against in order to pump the blood around the body. This reduces the pressure within the blood vessels. Amlodipine can therefore be used to treat high blood pressure.
The widening effect on the small arteries and the arteries in the heart also improves the blood and therefore oxygen supply to the heart. This feature means amlodipine can be used to treat angina. The chest pain of angina is caused by insufficient oxygen supply to the heart. As amlodipine improves this oxygen supply, and also reduces the effort the heart has to make to pump blood, it can be taken regularly to prevent angina attacks
Bendrofluazide: A thiazide diuretic with actions and uses similar to those of HYDROCHLORTHIAZIDE. It has been used in the treatment of familial hyperkalemia, hypertension, edema, and urinary tract disorders.
There you go....Good Luck!
