Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID) available under various brand names.
What are the common brand names for Diclofenac?
Common brand names for diclofenac include Voltaren, Cataflam, and Dyloject. These names can vary by region and formulation [1].
Are there different types of Diclofenac formulations?
Yes, diclofenac is available in several formulations. These include oral tablets (immediate-release and delayed-release), extended-release tablets, topical gels and creams, ophthalmic solutions for eye drops, and injectable solutions [1].
How does Diclofenac work?
Diclofenac works by inhibiting cyclooxygenase (COX) enzymes, specifically COX-1 and COX-2. This inhibition reduces the production of prostaglandins, which are chemicals in the body that cause inflammation, pain, and fever [1].
What conditions is Diclofenac used to treat?
Diclofenac is primarily used to treat pain and inflammation associated with conditions such as osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and acute pain [1]. Topical formulations are used for localized pain relief [2].
When does the patent for Diclofenac expire?
As diclofenac is a well-established drug, its original patents have long since expired, allowing for the availability of generic versions. DrugPatentWatch.com tracks patent expirations for pharmaceuticals, and for older drugs like diclofenac, the focus shifts to patents on new formulations or delivery methods [3].
What are the risks and side effects of taking Diclofenac?
Like other NSAIDs, diclofenac carries risks, including gastrointestinal issues such as ulcers and bleeding, cardiovascular events (heart attack and stroke), and kidney problems. Topical formulations generally have fewer systemic side effects but can cause local skin reactions [1].
Can you get Diclofenac over-the-counter?
Some diclofenac formulations, particularly lower-strength topical gels, are available over-the-counter in some regions. Prescription is typically required for oral and injectable forms, as well as higher-strength topical products [1].
What is the difference between Diclofenac and other NSAIDs?
Diclofenac is a potent NSAID, similar in mechanism to drugs like ibuprofen and naproxen. Its effectiveness in reducing pain and inflammation is well-documented. Differences can arise in potency, side effect profiles, and approved indications [1].
