Nimesulide is a nonsteroidal arylsulfonamide with anti-inflammatory properties. Nimesulide inhibits the cyclooxygenase-mediated conversion of arachidonic acid to pro-inflammatory prostaglandins. Modestly selective for COX-2, this agent binds to the enzyme, thereby inactivating it. Nimesulide may inhibit some carcinogenic COX-2-related carcinogenic effects on xenobiotic metabolism, apoptosis, immune surveillance and angiogenesis (overexpressed COX-2 in tumor epithelial cells enhances production of vascular growth factors and the formation of capillary-like networks).

5 Pharmacology and Biochemistry
5.1 Pharmacology

Food, gender and advanced age have negligible effects on nimesulide pharmacokinetics.


5.2 MeSH Pharmacological Classification

Anti-Inflammatory Agents, Non-Steroidal

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. (See all compounds classified as Anti-Inflammatory Agents, Non-Steroidal.)


Cyclooxygenase Inhibitors

Compounds or agents that combine with cyclooxygenase (PROSTAGLANDIN-ENDOPEROXIDE SYNTHASES) and thereby prevent its substrate-enzyme combination with arachidonic acid and the formation of eicosanoids, prostaglandins, and thromboxanes. (See all compounds classified as Cyclooxygenase Inhibitors.)


5.3 ATC Code

M - Musculo-skeletal system

M01 - Antiinflammatory and antirheumatic products

M01A - Antiinflammatory and antirheumatic products, non-steroids

M01AX - Other antiinflammatory and antirheumatic agents, non-steroids

M01AX17 - Nimesulide


M - Musculo-skeletal system

M02 - Topical products for joint and muscular pain

M02A - Topical products for joint and muscular pain

M02AA - Antiinflammatory preparations, non-steroids for topical use

M02AA26 - Nimesulide


5.4 Absorption, Distribution and Excretion

Absorption

Rapidly absorbed following oral administration.


Route of Elimination

Renal (50%), fecal (29%)


5.5 Metabolism/Metabolites

Hepatic. Extensive biotransformation, mainly to 4-hydroxynimesulide (which also appears to be biologically active).


5.6 Biological Half-Life

1.84.7 hours


5.7 Mechanism of Action

The therapeutic effects of Nimesulide are the result of its complete mode of action which targets a number of key mediators of the inflammatory process such as: COX-2 mediated prostaglandins, free radicals, proteolytic enzymes and histamine.
