Diclofenac is a non-steroidal anti-inflammatory drugs (NSAID) used to relieve pain and reduce inflammation.
Diclofenac exists in two forms - the sodium salt (diclofenac sodium) and the potassium salt (diclofenac potassium). Each has the same amount of diclofenac base - the main difference is that diclofenac potassium is slightly more soluble in water than diclofenac sodium.
Diclofenac potassium is generally considered to be more quickly absorbed and have a faster onset of analgesic activity than diclofenac sodium.
Diclofenac exists in the following branded products for oral use
Cambia 50 mg (diclofenac potassium for oral solution)
Cataflam 50 mg (diclofenac potassium immediate-release tablets)
Voltaren 75 mg (diclofenac sodium enteric-coated tablets)
Voltaren-XR 100 mg (diclofenac sodium extended-release tablets)
Zipsor 25 mg (diclofenac potassium) Liquid Filled Capsules
The different formulations of diclofenac cannot be considered equivalent even if the dose is the same.
