🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionChlorzoxazone is absorbed from the gastrointestinal tract. Diclofenac is rapidly and completely absorbed after oral administration. Food may delay the rate but not the extent of absorption of diclofenac.
DistributionChlorzoxazone is distributed widely in the body. Diclofenac is highly bound to plasma proteins and distributes into synovial fluid.
Protein BindingChlorzoxazone: not established from the available information. Diclofenac: greater than 99% bound to plasma proteins, primarily albumin.
MetabolismChlorzoxazone is extensively metabolized in the liver, primarily by CYP2E1 to 6-hydroxychlorzoxazone. Diclofenac is metabolized in the liver by CYP2C9 to 4'-hydroxydiclofenac and by other pathways.
Half-LifeChlorzoxazone: approximately 1-2 hours. Diclofenac: approximately 1-2 hours.
ExcretionChlorzoxazone metabolites are excreted mainly in urine as glucuronide conjugates. Diclofenac metabolites are excreted in urine and bile.
BioavailabilityChlorzoxazone: not established from the available information. Diclofenac: approximately 50-60% due to first-pass metabolism.
Onset of ActionChlorzoxazone: within 1 hour. Diclofenac: within 30 minutes to 1 hour.
Peak Plasma TimeChlorzoxazone: 1-2 hours. Diclofenac: 1-2 hours (immediate-release).
Duration of ActionChlorzoxazone: 3-6 hours. Diclofenac: 4-6 hours.

How It Works

This medicine combines two active ingredients. Chlorzoxazone is a centrally acting muscle relaxant that primarily acts on the spinal cord and brainstem to inhibit polysynaptic reflexes, thereby reducing skeletal muscle spasm. Diclofenac is a non-steroidal anti-inflammatory drug that reversibly inhibits cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzymes, leading to decreased production of prostaglandins, which are mediators of pain and inflammation.

Mechanism Steps

1
Chlorzoxazone acts centrally: Chlorzoxazone inhibits polysynaptic reflexes in the spinal cord and brainstem, reducing muscle spasm.
2
Diclofenac inhibits COX enzymes: Diclofenac reversibly inhibits COX-1 and COX-2, decreasing prostaglandin synthesis.
3
Reduced prostaglandins: Lower prostaglandin levels reduce inflammation, pain, and fever.
4
Combined effect: Muscle relaxation and anti-inflammatory action together alleviate musculoskeletal pain and spasm.
