FDA approves blood-thinning drug Brilinta to treat acute coronary syndromes (USA)

The U.S. Food and Drug Administration has approved the blood-thinning drug Brilinta (ticagrelor) to reduce cardiovascular death and heart attack in patients with acute coronary syndromes (ACS). ACS includes a group of symptoms for any condition, such as unstable angina or heart attack, that could result from reduced blood flow to the heart. Brilinta works by preventing the formation of new blood clots, thus maintaining blood flow in the body to help reduce the risk of another cardiovascular event. Brilinta has been studied in combination with aspirin. A boxed warning to health care professionals and patients warns that aspirin doses above 100 milligrams per day decrease the effectiveness of the medication

AstraZeneca shares hit by US drug approval delay

"Shares in AstraZeneca dropped 5% in early London trading after US regulators further delayed approval of its heart drug Brilinta. Markets had expected the UK drugmaker's blood thinner to get the go-ahead. The US Food and Drug Administration (FDA) said it wanted further analysis of existing drugs studies, although no further studies are needed. Brilinta, which is already approved in Europe, is expected to reach $2bn (£1.3bn) sales in the US once approved. The FDA had already postponed its review of the heart drug since September after patients in a North American trial of the drug failed to show significant benefits. AstraZeneca is hoping Brilinta will challenge Plavix produced by rivals Bristol-Myers Squibb and Sanofi-Aventis, which is the second best-selling drug in the world with over $9.5bn sales last year. The UK company is about to see patents on some of its other major brands expire, including schizophrenia drug Seroquel and heartburn relief Nexium" - BBC
