Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID) used to treat pain and inflammatory disorders such as osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis. The 'combinations' formulation refers to diclofenac used in combination with other agents, most commonly with misoprostol to reduce gastric side effects, or with other analgesics for enhanced efficacy. Diclofenac combinations are commonly approved and still in clinical use today.
Pharmacokinetics
Estimated typical pharmacokinetic parameters for healthy adult subjects receiving oral diclofenac in combination products.
