🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionNimesulide is rapidly absorbed after oral administration. Paracetamol is also well absorbed from the gastrointestinal tract. However, specific absorption data for this fixed-dose combination tablet are not established from the available information.
DistributionNimesulide is highly protein-bound and distributes into tissues. Paracetamol distributes widely into body fluids. Specific distribution data for this combination are not established from the available information.
Protein BindingNimesulide is approximately 95% bound to plasma proteins. Paracetamol is only weakly bound to plasma proteins. Specific protein binding data for this combination are not established from the available information.
MetabolismNimesulide is extensively metabolized in the liver, primarily by CYP2C9, to several metabolites. Paracetamol is metabolized in the liver via glucuronidation and sulfation, and a small fraction via CYP2E1 to a toxic metabolite (NAPQI) that is normally detoxified by glutathione. Specific metabolism data for this combination are not established from the available information.
Half-LifeThe elimination half-life of Nimesulide is approximately 2 to 5 hours. The elimination half-life of Paracetamol is approximately 2 to 3 hours. Specific half-life data for this combination are not established from the available information.
ExcretionNimesulide and its metabolites are excreted primarily in urine and feces. Paracetamol metabolites are excreted mainly in urine. Specific excretion data for this combination are not established from the available information.
BioavailabilityThe oral bioavailability of Nimesulide is approximately 80% to 90%. The oral bioavailability of Paracetamol is approximately 80% to 90%. Specific bioavailability data for this combination are not established from the available information.
Onset of ActionThe onset of analgesic and antipyretic effects is typically within 30 to 60 minutes after oral administration. Specific onset data for this combination are not established from the available information.
Peak Plasma TimePeak plasma concentrations of Nimesulide are reached in about 1.5 to 3 hours. Peak plasma concentrations of Paracetamol are reached in about 0.5 to 2 hours. Specific peak plasma time for this combination is not established from the available information.
Duration of ActionThe duration of analgesic and antipyretic effects is typically 4 to 6 hours. Specific duration data for this combination are not established from the available information.

How It Works

This medicine combines two active ingredients with complementary mechanisms. Nimesulide is a non-steroidal anti-inflammatory drug that selectively inhibits cyclooxygenase-2 (COX-2) and also has additional effects on neutrophil function and cytokine production, leading to reduced prostaglandin synthesis and decreased inflammation and pain. Paracetamol acts primarily in the central nervous system by inhibiting prostaglandin synthesis and modulating pain perception, and it also affects the hypothalamic heat-regulating center to reduce fever. Together, they provide analgesic, anti-inflammatory, and antipyretic effects.

Mechanism Steps

1
COX-2 inhibition by Nimesulide: Nimesulide selectively inhibits the cyclooxygenase-2 enzyme, reducing the production of prostaglandins that mediate inflammation and pain.
2
Additional anti-inflammatory actions of Nimesulide: Nimesulide also inhibits neutrophil activation, reduces cytokine release, and scavenges free radicals, contributing to its anti-inflammatory effect.
3
Central analgesic and antipyretic action of Paracetamol: Paracetamol acts on the central nervous system to inhibit prostaglandin synthesis and modulate pain perception, and it reduces fever by acting on the hypothalamic heat-regulating center.
4
Combined effect: The combination provides enhanced relief from pain and fever compared to either agent alone, with a relatively lower dose of each component.
