Diclofenac Sodium 50mg + Paracetamol 325mg (Bilayer) is a bilayer tablet formulation designed to provide extended pain relief. The first layer contains diclofenac sodium, a nonsteroidal anti-inflammatory drug (NSAID) that works by inhibiting the production of chemicals that cause inflammation, pain, and fever. The second layer contains paracetamol (acetaminophen), which helps to relieve pain and reduce fever. This combination is typically used to manage moderate to severe pain, such as in osteoarthritis, rheumatoid arthritis, muscle pain, or post-operative pain, offering both immediate and extended pain relief.
