Diclofenac sodium is also known by its brand name, Voltaren [1].
What are the different forms of diclofenac?
Diclofenac is available in various formulations, including oral tablets, extended-release tablets, topical gels, patches, and suppositories [2].
How does diclofenac work?
Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID) that works by inhibiting cyclooxygenase (COX) enzymes. These enzymes are responsible for the production of prostaglandins, which are involved in pain, inflammation, and fever [3]. By reducing prostaglandin synthesis, diclofenac alleviates these symptoms [3].
When does the patent for diclofenac expire?
Diclofenac is an older drug, and its original patents have long since expired [4]. This has allowed for the development and marketing of generic versions [4].
Who manufactures generic diclofenac?
Numerous pharmaceutical companies produce generic diclofenac sodium. Specific manufacturers can vary by region and availability [5].
What is diclofenac used to treat?
Diclofenac is prescribed to treat pain and inflammation associated with conditions such as arthritis, osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, gout, and menstrual cramps [2][6]. The topical formulations are often used for localized muscle and joint pain [2].
What are the potential side effects of diclofenac?
Common side effects of diclofenac can include stomach upset, nausea, diarrhea, constipation, dizziness, and headache [7]. More serious side effects, though less common, can involve gastrointestinal bleeding, heart problems, kidney issues, and allergic reactions [7].
Are there alternatives to diclofenac?
Yes, other NSAIDs like ibuprofen, naproxen, and celecoxib are available as alternatives for pain and inflammation [8]. Acetaminophen is another option for pain relief, though it does not have significant anti-inflammatory properties [8]. For some types of pain, other classes of medication may be considered [8].
How does diclofenac compare to other NSAIDs?
Diclofenac is generally considered a potent NSAID with effective anti-inflammatory and analgesic properties [3]. Like other NSAIDs, it carries risks for gastrointestinal and cardiovascular side effects [3][7]. The specific choice of NSAID often depends on individual patient factors, including medical history and tolerance [3].
