Voltaren (diclofenac): uses and effects

The Voltaren is the trademark of an active ingredient known as diclofenac. An active substance is a chemical that triggers an effect on the body. In this sense, diclofenac is a drug that belongs to the family of NSAIDs or non-steroidal anti-inflammatory drugs.

In this way, this drug It is indicated to reduce inflammations and treat pain, that is, the same pathologies as the rest of the drugs in their chemical category. An example of its use is to reduce menstrual cramps.

However, Other indications of diclofenac are different rheumatic diseases, which we will see later, gout attacks and kidney stones.

Next, we will explain some of the indications of the Voltaren in order to better understand its effects on the organism.

How does Voltaren exert its effect on the organism?

The Voltaren or Diclofenac It is a phenylacetic derivative that has a mechanism of action like that of other NSAIDs. As with them, this mechanism is not fully known.

It seems to involve the inhibition of enzymes known as cyclooxygenases. Cyclooxygenase or COX is an enzyme that allows the body to synthesize substances called prostaglandins from another chemical, arachidonic acid.

However, the mechanism of action of diclofenac may also be related to the inhibition of prostaglandin synthesis, which are substances that participate in inflammatory responses and stimulate the nerve terminals of pain.

Thus, Diclofenac acts by inhibiting cyclooxygenase and, thus, the production of prostaglandins Finally, reduce pain and inflammation.

On the other hand, these substances also have another series of functions such as maintain the integrity and proliferation of the gastric mucosa, as they ensure adequate blood flow.

This mucosa is responsible for protecting the stomach from irritating substances or microorganisms. Therefore, since this synthesis of prostaglandins is inhibited, the gastric mucosa is unprotected and it is the reason why these drugs can trigger a peptide ulcer.

Rheumatoid arthritis and Voltaren

In addition to fighting menstrual cramps, This drug is widely used for arthritic diseases.. Rheumatoid arthritis is a chronic inflammatory disorder that mostly affects the joints.

In some people, the disorder can damage different parts of the body In addition to joints such as skin, eyes or lungs. Rheumatoid arthritis is an autoimmune disorder that appears when the immune system mistakenly attacks body tissues triggered episodes of pain and inflammation.

It is another rheumatic disease for which Voltaren is used. Unlike rheumatoid arthritis, osteoarthritis only affects the joints and not to other parts of the body. It is the most common type of arthritis.

This disease damages the cartilage of the joints. Thus, the bone ceases to have protection against friction with other bones and these begin to collide directly. This friction involves pain, inflammation and loss of movement in the joint.

Over time, the joint usually loses its normal appearance. Additional bone spurs or bone growth may appear at the edges of the joint. Further, some structures of the joint can break off causing more pain.

And ankylosing spondylitis?

This is another indication of the Votaren. It is a rheumatic disease that course with inflammation of the joints of the spine and sacroiliac. It usually manifests with pain pictures in the lower back that can affect the entire spine and peripheral joints.

Ankylosing spondylitis may be accompanied by extra-articular symptoms as inflammation in the eyes or heart valves.

Today the cause of this disease is not known, but it has been linked to genetic factors. Further, it affects men more than women and usually manifests in adolescence or youth.
