How Does Diclofenac 75mg/3ml Injection Works?
Diclofenac 75mg/3ml Injection works by inhibiting cyclooxygenase (COX) enzymes responsible for prostaglandin synthesis in the body. Prostaglandins are chemical mediators that trigger pain, inflammation, and swelling at sites of injury or tissue damage, contributing to discomfort and reduced mobility.
By reducing prostaglandin production, Diclofenac Injection provides rapid relief from pain and inflammation. This helps improve movement, decrease swelling, and restore comfort in acute conditions. Its injectable form allows faster onset of action compared to oral medications in emergency situations.
