Diclofenac sodium is available under several brand names, with Voltaren being one of the most recognized [1]. Other brand names for diclofenac sodium include Cataflam and Solaraze [1].
What forms does diclofenac sodium come in?
Diclofenac sodium is formulated in various strengths and forms, including oral tablets, extended-release tablets, topical gels, ophthalmic solutions, and suppositories [1].
How long does diclofenac sodium stay in your system?
The duration diclofenac sodium remains in your system depends on the formulation and individual metabolism. For oral immediate-release tablets, the half-life is typically around 1.2 to 1.8 hours, meaning its concentration in the body reduces by half within that timeframe [2]. Extended-release formulations have a longer absorption period [1].
What are the common side effects of diclofenac sodium?
Common side effects associated with diclofenac sodium include gastrointestinal issues such as stomach pain, nausea, vomiting, diarrhea, indigestion, and constipation [2]. Other potential side effects can involve dizziness, headache, and skin rash [2].
Can diclofenac sodium cause serious health problems?
Yes, diclofenac sodium, like other nonsteroidal anti-inflammatory drugs (NSAIDs), carries a risk of serious health problems. These include an increased risk of cardiovascular events such as heart attack and stroke, especially with prolonged use or in individuals with pre-existing heart conditions [2]. It can also lead to serious gastrointestinal bleeding and ulcers [2]. Kidney problems and liver issues are also potential concerns [2].
When does the patent for diclofenac sodium expire?
Diclofenac sodium is an older medication, and its original patents have long expired, making it available as a generic drug [3].
Are there alternatives to diclofenac sodium for pain relief?
Yes, there are several alternatives to diclofenac sodium for pain relief. Other NSAIDs like ibuprofen and naproxen are available, as well as acetaminophen. For certain types of pain, opioids may be prescribed, and non-pharmacological treatments such as physical therapy, exercise, and acupuncture can also be considered [4].
How does diclofenac sodium work?
Diclofenac sodium works by inhibiting cyclooxygenase (COX) enzymes, specifically COX-1 and COX-2 [2]. These enzymes are involved in the production of prostaglandins, which are chemicals that contribute to inflammation, pain, and fever [2]. By reducing prostaglandin synthesis, diclofenac sodium effectively reduces these symptoms.
What is the difference between diclofenac sodium and diclofenac potassium?
The primary difference between diclofenac sodium and diclofenac potassium lies in their absorption rates. Diclofenac potassium is absorbed more rapidly, leading to a quicker onset of pain relief compared to diclofenac sodium [2].
Can diclofenac sodium be used during pregnancy?
The use of diclofenac sodium during pregnancy is generally advised against, particularly in the third trimester, due to potential risks to the fetus, including premature closure of the ductus arteriosus [2]. It is essential to consult a healthcare professional for guidance regarding medication use during pregnancy.
