Aspirin is one of the most well-known non-steroidal anti-inflammatory drugs used in modern medical practice.

Release form and composition

The active substance is acetylsalicylic acid serving as the basis for many drugs, the so-called “salicylates”. Pharmacies medicine can be purchased in tablets of 100 or 500 mg of the active ingredient, as well as in the form of effervescent tablets in which the content of active substance is equal to 350 mg.

Pharmacological action

According to the fact that this tool is a NSAID (non-steroidal anti-inflammatory drug), it has anti-inflammatory, antipyretic and analgesic effect. The effectiveness of Aspirin is due to the influence of acetylsalicylic acid on COX-2 (cyclooxygenase) that is responsible for the production of prostaglandins, and thus for the development of inflammation, pain and fever. This drug has antiplatelet effects, and thus, it thins the blood and inhibits platelet aggregation. So, Aspirin reduces mortality in case of unstable angina and myocardial infarction.
