Description

General description

Aspirin (acetylsalicylic acid) is a nonsteroidal anti-inflammatory drug. It occurs as white crystalline powder and is derived from salicylic acid.

Application

Aspirin has been used:

• as a stabilizer for blood during 13,14-dihydro-15-keto-prostaglandin F2α (PGFM) measurement
• to evaluate cell viability of BV-2 microglial cell line
• in morphogenesis assay

Biochem/physiol Actions

Aspirin is an analgesic and antipyretic agent used in the treatment of fever and pain as in arthritis. It is also associated with cardiovascular diseases.

Blocks the production of prostaglandins by inhibiting cyclooxygenase (prostaglandin H synthase), with greater selectivity toward the COX-1 isoform. The antithrombotic effect is due to the inhibition of COX-1 in platelets that blocks thromboxane production and platelet aggregation. Chemopreventive against colorectal and other solid tumors.
