🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
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
