Aspirin uses vary according to its strength. In a low dose (about 75 mg), Aspirin acts as a blood-thinning or antiplatelet agent used to prevent heart attack and stroke. On the other hand, a high dose (about 325 mg) acts as an analgesic, relieving minor aches, pains and fevers. Your doctor may also prescribe this immediately after a heart attack to prevent further clots and heart tissue death. CV Sprin 75mg Tablet contains Aspirin, which plays a vital role in the thinning of blood to decrease the risk of blood clot formation and subsequent heart attack. Low-dose aspirin makes the blood less sticky, preventing the risk of heart attack and stroke. Besides this, it inhibits the activity of the cyclooxygenase (COX) and prostaglandins (PGs), which cause inflammation, swelling, pain, and fever. In some cases, you may experience side effects such as stomach upset, heartburn, drowsiness, mild headache, ankle swelling (oedema), slow heart rate, and nausea.
