How Does Tiaprofenic Acid Work?

Tiaprofenic acid is a type of drug called a non-steroidal anti-inflammatory drug (NSAID). It works by stopping the production of compounds called prostaglandins in the body, which have a number of effects, including to cause inflammation.

As a result, tiaprofenic acid can help to reduce pain and inflammation by stopping the production of prostaglandins. This is why it is usually used to relieve painful inflammatory conditions, such as rheumatoid arthritis and osteoarthritis.

How does Tiaprofenic acid work?

Tiaprofenic acid works by inhibiting COX-1 and COX-2, which are needed to produce the different prostaglandins in your body. You have many different types of prostaglandins in your body, and there are some in almost every tissue of your body. They each have different effects, such as to cause:

• the tissues in your body to become inflamed

• your blood vessels to relax and widen

• the platelets in your blood to come together to form a clot
