Difference between Diclofenac and Diclofenac Potassium?

My doctor has given me both medications (at seperate times) for my rheumatoid arthritis, but I want to know the difference between Diclofenac and Diclofenac Potassium.
Thanks
Answer:
When a doctor states "diclofenac" on a prescription (s)he is generally refering to diclofenac sodium. Diclofenac potassium is the same drug but it is prepared as a different salt. Diclofenac potassium generally considered to be faster acting than the sodium salt as it goes into solution faster so it gets to it's site of action faster.
The two names refer to the same drug. Diclofenac is available either as the sodium or the potassium salt, never on its own. If your doctor wrote "Diclofenac" on the prescription, the pharmacist understands that he is referring to either the sodium or the potassium salt. Whichever is available in your country.
