Diclofenac is one of the most widely used anti-inflammatory drugs. It is available in any pharmacy. It is part of the non-steroidal anti-inflammatory drugs (NSAIDs).
The use of antibiotics, anti-inflammatory drugs and analgesics was almost nil a little more than a century ago. These types of drugs became known relatively few decades ago. In fact, their first uses caused more problems than relief.
With regard to diclofenac, its use is considered safe. However, there are certain precautions and side effects to be aware of, so that the OTC drug does not cause health problems, but rather brings benefits.

WHAT IS DICLOFENAC?
Diclofenac is a cyclooxygenase inhibitor of proven effectiveness. It belongs to the group of NSAIDs (non-steroidal anti-inflammatory drugs).
It is widely used to relieve pain and inflammation, including joint pain, postoperative pain, pain due to kidney and gallstones, menstrual cramps, among others.
There are two presentations of this drug: diclofenac sodium and diclofenac potassium.
DIFFERENCE BETWEEN DICLOFENAC SODIUM AND DICLOFENAC POTASSIUM
These two drugs contain the same effectiveness, since their base is diclofenac. However, the difference between one and the other is the way it is absorbed in the body. For this reason, some specialists prefer the use of one over the other.
Diclofenac potassium is absorbed faster than diclofenac sodium, since it is soluble in water. Therefore, if pain needs to be treated immediately, the potassium is best.
However, sodium, being of slower absorption, it is effective and prolonged in reducing inflammation. It is prescribed to treat arthritis. It should be noted that low doses are generally recommended.
Diclofenac potassium is better than diclofenac sodium when it comes to acute pain, thanks to its fast response time.
On the other hand, sodium diclofenac potassium is better for patients with chronic pain, ideal for reducing inflammation and can be used for a longer period of time.
