Product Name: Carbaspirin calcium Synonyms: carbasalate calcium; calcium 2-(acetyloxy)benzoate – urea (1:2:1) CAS RN.: 5749-67-7 EINECS: 227-273-0 Molecular Weight: 459.44016 Molecular Formula: C19H19CaN2O9 Anti-inflammatory agents that are non-steroidal in nature. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions.They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects.
