🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionAceclofenac is rapidly absorbed after oral administration, with peak plasma concentrations reached within 1.5 to 2 hours. Paracetamol is also rapidly and completely absorbed from the gastrointestinal tract, with peak plasma levels occurring within 0.5 to 2 hours. Food may delay the absorption of aceclofenac but does not significantly affect the extent of absorption.
DistributionAceclofenac is highly protein-bound (greater than 99%) and distributes well into synovial fluid, which is beneficial for joint pain relief. Paracetamol distributes widely throughout most body tissues, with a volume of distribution of approximately 0.9 L/kg.
Protein BindingAceclofenac: greater than 99% bound to plasma proteins. Paracetamol: approximately 10-25% bound to plasma proteins.
MetabolismAceclofenac is metabolized in the liver primarily by cytochrome P450 enzymes (CYP2C9) to 4'-hydroxyaceclofenac and other metabolites. Paracetamol is metabolized in the liver via glucuronidation and sulfation, with a small fraction metabolized by CYP2E1 to a toxic intermediate (NAPQI) that is normally detoxified by glutathione.
Half-LifeAceclofenac: approximately 3-4 hours. Paracetamol: approximately 2-3 hours.
ExcretionAceclofenac and its metabolites are excreted primarily in the urine (about 70-80%) and feces (about 20%). Paracetamol metabolites are excreted mainly in the urine.
BioavailabilityAceclofenac: approximately 80-100%. Paracetamol: approximately 80-100%.
Onset of ActionPain relief typically begins within 30-60 minutes after oral administration.
Peak Plasma TimeAceclofenac: 1.5-2 hours. Paracetamol: 0.5-2 hours.
Duration of ActionPain relief lasts approximately 4-6 hours, requiring dosing every 8-12 hours as prescribed.

How It Works

This medicine combines two active ingredients with complementary mechanisms. Aceclofenac, an NSAID, inhibits the cyclooxygenase (COX) enzymes, particularly COX-2, leading to decreased synthesis of prostaglandins, which are mediators of pain, inflammation, and fever. Paracetamol, though its exact mechanism is not fully understood, primarily acts centrally to inhibit prostaglandin synthesis in the brain and may also modulate pain perception through other pathways. Together, they provide effective analgesia and anti-inflammatory action.

Mechanism Steps

1
Inhibition of cyclooxygenase enzymes: Aceclofenac inhibits COX-1 and COX-2 enzymes, reducing the conversion of arachidonic acid to prostaglandins.
2
Reduced prostaglandin synthesis: Decreased prostaglandin levels lead to reduced inflammation, pain, and fever.
3
Central analgesic action of paracetamol: Paracetamol acts on the central nervous system to inhibit prostaglandin synthesis and modulate pain perception.
4
Combined analgesic and anti-inflammatory effect: The dual action provides enhanced pain relief and anti-inflammatory benefits compared to either agent alone.
