🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionAceclofenac is rapidly absorbed from the gastrointestinal tract after oral administration. Chlorzoxazone is also well absorbed from the gastrointestinal tract. Food may slightly delay the absorption of aceclofenac but does not significantly affect the extent of absorption.
DistributionAceclofenac is highly protein-bound and distributes into synovial fluid, which is beneficial for joint pain. Chlorzoxazone is widely distributed in the body, including the central nervous system.
Protein BindingAceclofenac is approximately 99% bound to plasma proteins. Chlorzoxazone is about 70% bound to plasma proteins.
MetabolismAceclofenac is metabolised in the liver, primarily by cytochrome P450 enzymes, to several metabolites including 4'-hydroxyaceclofenac. Chlorzoxazone is extensively metabolised in the liver, mainly by CYP2E1, to 6-hydroxychlorzoxazone, which is inactive.
Half-LifeThe elimination half-life of aceclofenac is approximately 3 to 4 hours. The elimination half-life of chlorzoxazone is approximately 1 to 2 hours.
ExcretionAceclofenac and its metabolites are excreted primarily in the urine and to a lesser extent in the faeces. Chlorzoxazone is excreted mainly in the urine as its glucuronide conjugate.
BioavailabilityThe oral bioavailability of aceclofenac is approximately 80 to 100%. The bioavailability of chlorzoxazone is not well established but is considered adequate for therapeutic effect.
Onset of ActionThe onset of pain relief from aceclofenac is typically within 30 to 60 minutes after oral administration. The muscle relaxant effect of chlorzoxazone usually begins within 1 hour.
Peak Plasma TimeAceclofenac reaches peak plasma concentration in about 1.5 to 2 hours. Chlorzoxazone reaches peak plasma concentration in about 1 to 2 hours.
Duration of ActionThe analgesic and anti-inflammatory effects of aceclofenac last for about 6 to 8 hours. The muscle relaxant effect of chlorzoxazone lasts for about 4 to 6 hours. The combination is usually taken two to three times daily.

How It Works

This medicine combines two active ingredients with complementary mechanisms. Aceclofenac is a non-steroidal anti-inflammatory drug that inhibits the cyclooxygenase enzymes, particularly COX-2, thereby reducing the production of prostaglandins that mediate pain, inflammation, and fever. Chlorzoxazone is a centrally acting skeletal muscle relaxant that primarily acts on the spinal cord and subcortical areas of the brain to reduce muscle spasm. It inhibits polysynaptic and monosynaptic reflexes in the spinal cord, leading to relaxation of skeletal muscles. Together, these actions provide relief from both inflammation and muscle spasm, which is beneficial in musculoskeletal pain conditions.

Mechanism Steps

1
Aceclofenac inhibits COX enzymes: Aceclofenac blocks the cyclooxygenase enzymes, especially COX-2, reducing the conversion of arachidonic acid to prostaglandins.
2
Reduced prostaglandin synthesis: Lower prostaglandin levels decrease inflammation, pain, and swelling at the site of injury.
3
Chlorzoxazone acts centrally: Chlorzoxazone acts on the spinal cord and brain to inhibit polysynaptic reflexes, reducing muscle spasm.
4
Muscle relaxation: Inhibition of reflexes leads to relaxation of skeletal muscles, relieving spasm and associated pain.
5
Combined analgesic effect: The combination provides both anti-inflammatory and muscle relaxant effects, improving overall pain relief.
