Aniracetam is not aspirin. Anacin and aspirin are both antipyretic and anti-inflammatory drugs. The anti-inflammatory effect of antipyretic and anti-inflammatory drugs is different from the anti-inflammatory effect of glucocorticoids, also known as non-steroidal anti-inflammatory drugs. Non-steroidal anti-inflammatory drugs work by inhibiting the activity of cyclooxygenase in the body and reducing the synthesis of prostaglandins in local tissues. Anacin belongs to the pyrazolone class of non-steroidal anti-inflammatory drugs, is the combination of aminopyrine and sodium sulfite to form a compound, antipyretic and analgesic effect is strong, rapid onset of action, and a relatively strong anti-rheumatic effect, but the side effects are many and serious, many countries in the world has long been banned. Aspirin, also known as acetylsalicylic acid, belongs to the salicylic acid class of non-steroidal anti-inflammatory drugs, because the antipyretic and analgesic effects are not strong, now the main use of anti-platelet effect to prevent thrombosis.
