🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionFollowing intramuscular injection, nimesulide is rapidly and completely absorbed. The bioavailability is high, and peak plasma concentrations are reached within 30 to 60 minutes. The rate of absorption may vary depending on the injection site and blood flow.
DistributionNimesulide is highly bound to plasma proteins and distributes extensively into body tissues, including synovial fluid. It crosses the placental barrier and is excreted in breast milk. The volume of distribution is approximately 0.2 L/kg.
Protein BindingNimesulide is approximately 99% bound to plasma proteins, primarily to albumin.
MetabolismNimesulide is extensively metabolized in the liver, mainly by cytochrome P450 enzymes, particularly CYP2C9. The primary metabolite is 4-hydroxynimesulide, which is pharmacologically active but less potent than the parent drug.
Half-LifeThe elimination half-life of nimesulide is approximately 2 to 5 hours, but it may be prolonged in patients with liver or kidney impairment.
ExcretionNimesulide and its metabolites are excreted primarily through the kidneys (about 70%) and in feces (about 30%).
BioavailabilityThe bioavailability of intramuscular nimesulide is approximately 90% or higher, indicating near-complete absorption.
Onset of ActionPain relief typically begins within 15 to 30 minutes after intramuscular injection.
Peak Plasma TimePeak plasma concentration is reached approximately 30 to 60 minutes after intramuscular administration.
Duration of ActionThe analgesic effect lasts for about 6 to 8 hours, and the anti-inflammatory effect may persist longer.

How It Works

This medicine works by selectively inhibiting the cyclooxygenase-2 (COX-2) enzyme, which is responsible for producing prostaglandins that mediate pain, inflammation, and fever. By blocking COX-2, it reduces the synthesis of these prostaglandins, leading to analgesic, anti-inflammatory, and antipyretic effects. Unlike non-selective NSAIDs, it has less effect on COX-1, which may reduce gastrointestinal side effects, but the risk is not eliminated, especially with injectable use.

Mechanism Steps

1
Inhibition of COX-2 enzyme: This medicine binds to and inhibits the COX-2 enzyme, preventing the conversion of arachidonic acid to prostaglandin H2.
2
Reduced prostaglandin synthesis: This leads to decreased production of prostaglandins such as PGE2 and PGI2, which are key mediators of pain and inflammation.
3
Analgesic and anti-inflammatory effects: The reduction in prostaglandins results in less pain, swelling, and fever.
