Main applications
Naproxen is a non steroidal anti-inflammatory and analgesic drug used to alleviate fever, inflammation, and pain associated with arthritis or other symptoms. It has anti-inflammatory, antipyretic, and analgesic effects. Naproxen USP works by inhibiting cyclooxygenase, an enzyme associated with the production of prostaglandins, an inflammatory mediator. Naproxen also has the following uses:
1. Naproxen can enhance the body's resistance and play a significant role in supplementing symptoms such as kidney qi deficiency and gastrointestinal motility fatigue caused by physical weakness.
2. Naproxen has a good inhibitory effect on Helicobacter pylori. It can effectively treat atrophic gastritis, superficial gastritis, and duodenal ulcers. In addition, improving the function of the gastrointestinal motility system can also promote the metabolism of gastric acid. Assist the body in digestion and absorption.
3. Naproxen also has excellent treatment for rheumatism and its symptoms. Many people who suffer from rheumatic diseases for a long time feel significantly relieved after taking Naproxen, so Naproxen is used for long-term control to prevent its recurrence.
4. Clinical trials have found that Naproxen USP can reasonably increase pancreatic activity, and the obvious practical effect is that it can lower the level of blood glucose volume, thereby restoring the volume of blood glucose to above normal levels.

FAQ
Q1:What is the difference between Naproxen and Ibuprofen?
A1:Both Ibuprofen and Naproxen can block cyclooxygenase-2 (COX-2) involved in pain signal transduction and inflammation, as well as cyclooxygenase-1 (COX-1) associated with protecting the gastric wall. The difference is that Naproxen has a long-lasting analgesic effect on pain caused by bone sprains, contusions, muscle injuries, arthritis, gout, etc. Naproxen has less gastrointestinal irritation.
Q2:How to produce Naproxen?
A2:2-Acetyl-6-methoxynaphthole is obtained by methylation and acetylation of 2-Naphthol, followed by condensation with chloroacetate, isomerization, hydrolysis, oxidation, neutralization, and separation reactions.
Q3: What are the chemical properties and characteristics of Naproxen?
A3:Almost insoluble in water, gradually changing color when exposed to light.
