Complex mechanism of action
The pharmacological effects of Nimesulidum are determined by multiple biochemical targets. The drug not only blocks COX-2, but also inhibits the activity of type IV phosphodiesterase and matrix metalloproteinases — enzymes that degrade articular cartilage.
In addition, the active substance reduces the synthesis and release of TNF-α (tumor necrosis factor-alpha), decreases neutrophil activity, and potentially interacts with glucocorticoid receptors. This multi-level approach provides a powerful anti-inflammatory result with a lower incidence of adverse reactions compared to non-selective agents.
Indications for use
The drug is in demand in medical practice due to its ability to rapidly cope with inflammation and pain of various origins. Main indications for prescription:
- Rheumatic diseases of articular and extra-articular nature.
- Various pain syndromes, including dental and menstrual pain, as well as spastic pain.
Safety profile and limitations
The key advantages of Nimesulidum include low gastrointestinal toxicity and chondroneutrality — the absence of negative impact on articular cartilage.
Nevertheless, the safety profile has important nuances:
- Side effects: dyspeptic disorders (nausea, epigastric pain), central nervous system reactions (headache, dizziness), and allergic manifestations are possible.
- Time limitations: the total duration of a continuous treatment course is no more than 15 days.
- Dangerous risks: the drug has potential hepatotoxicity (up to the development of severe hepatic failure). Because of this risk, the drug is especially dangerous in children and is completely banned for use in a number of countries.
Briefly: answers to topical questions
What are the absolute contraindications to prescribing nimesulide?
An absolute contraindication to prescribing nimesulide is age under 12 years for the tablet form. Nimesulide is also restricted due to the risk of hepatotoxicity and hepatic failure; in a number of countries, it is banned for use for this reason, especially in children.
With which drugs does nimesulide enter into clinically significant drug interactions?
Nimesulide should not be prescribed concomitantly with other NSAIDs. Co-administration with glucocorticoids, anticoagulants, methotrexate, bisphosphonates, and low-dose aspirin increases the risk of NSAID-induced gastropathy.

Class and exam questions
What main mechanism of action distinguishes Nimesulide from classical NSAIDs?
The drug acts comprehensively: in addition to selective COX-2 inhibition, it suppresses type IV phosphodiesterase, inhibits cartilage-destroying matrix metalloproteinases, and reduces the production of tumor necrosis factor-alpha (TNF-α).
What are the main limitations and risks when prescribing the drug?
The course of treatment is strictly limited and must not exceed 15 days. The main serious risk is associated with hepatotoxicity and the possible development of hepatic failure, especially in children.
How does Nimesulide affect articular cartilage?
The drug possesses the property of chondroneutrality: it inhibits metalloproteinase enzymes that destroy cartilage and generally does not exert a negative effect on joint tissues.
