Diclofenac's active ingredient is diclofenac, which is a nonsteroidal anti-inflammatory drug (NSAID). It is available in various salt forms, including diclofenac sodium and diclofenac potassium [1]. These salts are the pharmaceutical forms of the active substance that provide the therapeutic effect [1].
What else is in diclofenac medications?
Beyond the active ingredient, diclofenac formulations contain inactive ingredients, also known as excipients. These vary depending on the dosage form (e.g., tablets, capsules, topical gels, patches). Common excipients in oral diclofenac tablets can include fillers like microcrystalline cellulose and lactose, binders such as povidone, disintegrants like croscarmellose sodium, and lubricants such as magnesium stearate [1]. Topical formulations might contain gelling agents, solvents, and penetration enhancers [1].
How do diclofenac sodium and potassium differ?
Diclofenac sodium and diclofenac potassium are different salt forms of the same active drug, diclofenac. Diclofenac potassium is often formulated for faster absorption, which may lead to quicker pain relief compared to diclofenac sodium [2]. Both forms work by reducing hormones that cause inflammation and pain in the body [3].
When do diclofenac patents expire?
Drug patent information is dynamic and subject to change through various legal processes. For detailed and up-to-date information on diclofenac patents, including expiration dates and potential challenges, resources such as DrugPatentWatch.com can be consulted [4].
What are the common uses for diclofenac?
Diclofenac is used to treat pain and inflammation associated with various conditions, including osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis [3]. It is also prescribed for acute pain, menstrual cramps, and certain types of headaches [3]. Topical forms are often used for localized muscle or joint pain [3].
What are the risks associated with diclofenac?
Like other NSAIDs, diclofenac carries risks, including gastrointestinal bleeding, ulcers, and perforation. Cardiovascular risks, such as heart attack and stroke, can also occur. Other potential side effects include kidney problems, high blood pressure, and allergic reactions [3]. Patients with pre-existing heart conditions or those taking other NSAIDs are at increased risk [3].
Who manufactures diclofenac products?
Diclofenac is a widely available generic medication, meaning numerous pharmaceutical companies manufacture it. Major manufacturers and distributors of diclofenac products vary globally. Specific brand names include Voltaren, Cataflam, and Arthrotec (a combination product with misoprostol) [3].
